Sports Utility Vehicle

G WARNINGDue to the high center of gravity, the vehiclemay start to skid and roll over in the event ofan abrupt steering maneuver and/or whenthe vehicle's speed is not adapted to the roadconditions. There is a risk of an accident.Always adapt your speed and driving style tothe vehicle's driving characteristics and to theprevailing road and weather conditions.

Utility vehicles have a significantly higher roll-over rate than other types of vehicles.Failure to operate this vehicle safely may resultin an accident, rollover of the vehicle, and severeor fatal injury.In a rollover crash, an unbelted person is signif-icantly more likely to die than a person wearinga seat belt.You and all vehicle occupants should alwayswear your seat belts.

Event data recordersThis vehicle is equipped with an event datarecorder (EDR). This vehicle is equipped with anevent data recorder (EDR). The main purpose ofan EDR is to record, in certain crash or nearcrash-like situations, such as an air bag deploy-ment or hitting a road obstacle, data that willassist in understanding how a vehicle's systemsperformed. The EDR is designed to record datarelated to vehicle dynamics and safety systemsfor a short period of time, typically 30 secondsor less.The EDR in this vehicle is designed to recordsuch data as:RHow various systems in your vehicle wereoperatingRWhether or not the driver and passengersafety belts were buckled/fastenedRHow far (if at all) the driver was depressing theaccelerator and/or brake pedal andRHow fast the vehicle was travelingThese data can help provide a better under-standing of the circumstances in which crashesand injuries occur.

Occupant safety

Introduction to the restraint systemThe restraint system can reduce the risk of vehi-cle occupants coming into contact with parts ofthe vehicle's interior in the event of an accident.The restraint system can also reduce the forcestowhich vehicle occupants are subjected duringan accident.The restraint system comprises:Rseat belt systemRair bagsRchild restraint systemRchild seat securing systemsThe components of the restraint system work inconjunction with each other. They can onlydeploy their protective function if, at all times, allvehicle occupants:Rhave fastened their seat belts correctly(Y page 46)Rhave adjusted their seat and head restraintproperly (Y page 98).

As the driver, you also have to make sure thatthe steering wheel is adjusted correctly.Observe the information relating to the correctdriver's seat position (Y page 98).You also have to make sure that an air bag caninflate properly if deployed (Y page 48).An air bag supplements a correctly worn seatbelt. As an additional safety device, the air bagincreases the level of protection for vehicleoccupants in the event of an accident. For exam-ple, if, in the event of an accident, the protectionoffered by the seat belt is sufficient, the air bagsare not deployed.When an accident occurs, onlythe air bags that increase protection in that par-ticular accident situation are deployed. How-ever, seat belts and air bags generally do notprotect against objects penetrating the vehiclefrom the outside.Information on restraint system operation canbe found under "Triggering of the EmergencyTensioning Devices and air bags" (Y page 55).For information on children traveling with you inthe vehicle and on child restraint systems, see"Children in the vehicle" (Y page 59).


G WARNINGModifications to the restraint system maycause it to no longer work as intended. Therestraint system may then not perform itsintended protective function andmay fail in anaccident or trigger unexpectedly, for example.This poses an increased risk of injury or evenfatal injury.Never modify parts of the restraint system.Never tamper with the wiring, the electroniccomponents or their software.If it is necessary to modify components of therestraint system to accommodate a personwith disabilities, contact an authorizedMercedes-Benz Center for details. USA only:for further information contact our CustomerAssistance Center at 1-800-FOR-MERCedes(1‑800‑367‑6372).

Mercedes-Benz recommends that you only usedriving aids which have been approved specifi-cally for your vehicle by Mercedes-Benz.

Restraint system warning lampThe functions of the restraint system arechecked after the ignition is switched on and atregular intervals while the engine is running.Therefore, malfunctions can be detected ingood time.The 6 restraint system warning lamp in theinstrument cluster lights up when the ignition isswitched on. It goes out no later than a few sec-onds after the vehicle is started. The compo-nents of the restraint system are in operationalreadiness.Amalfunction has occurred if the 6 restraintsystem warning lamp:Rdoes not light up after the ignition is switchedonRdoes not go out after a few seconds with theengine runningRlights up again while the engine is running

G WARNINGIf the restraint system is malfunctioning,restraint system components may be trig-gered unintentionally or may not deploy asintended during an accident. This can affectfor example the Emergency TensioningDevice or the air bag. This poses an increasedrisk of injury or even fatal injury.Have the restraint system checked andrepaired in a qualified specialist workshop assoon as possible.

PASSENGER AIR BAG indicator lamp

PASSENGER AIR BAG ON indicator lamp: andPASSENGER AIR BAGOFF indicator lamp; arepart of the Occupant Classification System(OCS).

The indicator lamps display the status of thefront-passenger front air bag.RPASSENGER AIR BAG ON lights up for 60 sec-onds, subsequently both indicator lamps areoff (PASSENGER AIR BAG ON and OFF): thefront-passenger front air bag is able to deployin the event of an accident.RPASSENGER AIR BAGOFF lights up: the front-passenger front air bag is deactivated. It willthen not be deployed in the event of an acci-dent.

If the PASSENGER AIR BAG ON indicator lamp isoff, only the PASSENGER AIR BAG OFF indicatorlamp shows the status of the front-passengerfront air bag. The PASSENGER AIR BAG OFFindicator lamp may be lit continuously or be off.Depending on the person in the front-passengerseat, the front-passenger front air bag musteither be deactivated or enabled; see the fol-lowing points. You must make sure of this bothbefore and during a journey.RChildren in a child restraint system:whether the front-passenger front air bag isenabled or deactivated depends on the instal-led child restraint system, and the age andsize of the child. Therefore, be sure to observethe notes on the "Occupant ClassificationSystem (OCS)" (Y page 51) and on "Chil-dren in the vehicle" (Y page 59). There youwill also find instructions on rearward andforward-facing child restraint systems on thefront-passenger seat.RAll other persons: depending on the classi-fication of the person in the front-passengerseat, the front-passenger front air bag is ena-bled or deactivated (Y page 51). Be sure toobserve the notes on "Seatbelts“ (Y page 44) and "Air bags"(Y page 48). There you can also find infor-mation on the correct seat position.

Seat belts

IntroductionSeat belts are the most effective means ofrestricting the movement of vehicle occupantsin the event of an accident or the vehicle rollingover. This reduces the risk of vehicle occupantscoming into contact with parts of the vehicleinterior or being ejected from the vehicle. Fur-thermore, the seat belt helps to keep the vehicle

occupant in the best position in relation to theair bag.The seat belt system comprises:RSeat beltsREmergency Tensioning Devices for the frontseat belts and the outer seat belts in the rearRSeat belt force limiters for the front seat beltsand the outer seat belts in the rear

If the seat belt is pulled out of the belt outletquickly or with a jerky movement, the beltretractor locks. The belt strap cannot be extrac-ted any further.The Emergency Tensioning Device tightens theseat belt in an accident, pulling the belt closeagainst the body. However it does not pull thevehicle occupant back in the direction of thebackrest.The Emergency Tensioning Device does not cor-rect an incorrect seat position or the routing ofan incorrectly fastened seat belt.When triggered, a seat belt force limiter helps toreduce the force exerted by the seat belt on thevehicle occupant.The seat belt force limiters for the front seats aresynchronized with the front air bags, whichabsorb part of the deceleration force. This canreduce the force exerted on the vehicle occu-pants during an accident.

! If the front-passenger seat is unoccupied,do not insert the belt tongue into the buckle ofthe front-passenger seat. This may otherwiselead to the triggering of the Emergency Ten-sioning Device in the event of an accident,which will then need to be replaced.

Important safety notesThe use of seat belts and child restraint systemsis required by law in:Rall 50 statesRthe U.S. territoriesRthe District of ColumbiaRall Canadian provincesEvenwhere this is not required by law, all vehicleoccupants should correctly fasten their seatbelts before starting the journey.

G WARNINGIf the seat belt is not worn correctly, it cannotperform its intended protective function. Anincorrectly fastened seat belt can also cause

injuries, for example, in the event of an acci-dent or when braking or changing directionabruptly. This poses an increased risk of injuryor even fatal injury.Always ensure that all vehicle occupants havetheir seat belts fastened correctly and are sit-ting properly.

G WARNINGThe seat belt does not offer the intended levelof protection if you have not moved the back-rest to an almost vertical position.When brak-ing or in the event of an accident, you couldslide underneath the seat belt and sustainabdomen or neck injuries, for example. Thisposes an increased risk of injury or even fatalinjury.Adjust the seat properly before beginningyour journey. Always ensure that the backrestis in an almost vertical position and that theshoulder section of your seat belt is routedacross the center of your shoulder.

G WARNINGPersons less than 5 ft (1.50 m) tall cannotwear the seat belt correctly without an addi-tional and suitable restraint system. If theseat belt is not worn correctly, it cannot per-form its intended protective function. Anincorrectly fastened seat belt can also causeinjuries, for example, in the event of an acci-dent or when braking or changing directionabruptly. This poses an increased risk of injuryor even fatal injury.For this reason, always secure persons under5 ft (1.50m) tall in suitable additional restraintsystems.

If a child younger than twelve years old andunder 5 ft (1.50 m) in height is traveling in thevehicle:Ralways secure the child in a child restraintsystem suitable for this Mercedes-Benz vehi-cle. The child restraint systemmust be appro-priate to the age, weight and size of the childRalways observe the instructions and safetynotes on "Children in the vehicle"(Y page 59) in addition to the child restraint

G WARNINGThe seat belts may not perform their intendedprotective function if:Rthey are damaged, modified, extremelydirty, bleached or dyedRthe seat belt buckle is damaged orextremely dirtyRthe Emergency Tensioning Devices, beltanchorages or inertia reels have beenmodi-fied.

Seat belts may be damaged in an accident,although the damage may not be visible, e.g.due to splinters of glass.Modified or damagedseat belts may tear or fail, e.g. in an accident.Modified Emergency Tensioning Devicescould accidentally trigger or fail to deploywhen necessary. This poses an increased riskof injury or even fatal injury.Never modify the seat belts, Emergency Ten-sioning Devices, belt anchorages and inertiareels. Make sure that the seat belts areundamaged, not worn out and clean. Follow-ing an accident, have the seat belts checkedimmediately at a qualified specialist work-shop.

Only use seat belts that have been approved foryour vehicle by Mercedes-Benz.AMG Performance seat: this seat is designedfor the standard three-point seat belt. If youinstall anothermulti-point seat belt, e.g. sport orracing seat belts, the restraint system cannotprovide the best level of protection.

G WARNINGIf you feed seat belts through the opening inthe seat backrest, the seat backrest may bedamaged or may even break in the event of anaccident. This poses an increased risk ofinjury or even fatal injury.Only use the standard three-point seat belt.Never modify the seat belt system.

Proper use of the seat beltsObserve the safety notes on the seat belt(Y page 45).All vehicle occupants must be wearing the seatbelt correctly before beginning the journey. Alsomake sure that all vehicle occupants are alwayswearing the seat belt correctly while the vehicleis in motion.When fastening the seat belt, always make surethat:Rthe seat belt tongue is only inserted to the beltbuckle belonging to that seat.Rthe seat belt is tight across your body.Avoid wearing bulky clothing, e.g. a wintercoat.Rthe seat belt is not twisted.Only then can the forces which occur be dis-tributed over the area of the belt.Rthe shoulder section of the belt is alwaysrouted across the center of your shoulder.The shoulder section of the belt must notcome into contact with your neck or be routedunder your arm. Where possible, adjust theseat belt to the appropriate height.Rthe lap belt passes tightly and as low down aspossible across your lap.The lap belt must always be routed acrossyour hip joints and not across your abdomen.This applies particularly to pregnant women.If necessary, push the lap belt down to yourhip joint and pull it tight using the shouldersection of the belt.Rthe seat belt is not routed across sharp, poin-ted or fragile objects.If you have such items located on or in yourclothing, e.g. pens, keys or eyeglasses, storethese in a suitable place.Ronly one person is using a seat belt at a time.Infants and children must never travel sittingon the lap of a vehicle occupant. In the eventof an accident, they could be crushedbetween the vehicle occupant and seat belt.Robjects are never secured with a seat belt ifthe seat belt is also being used by one of thevehicle's occupants.Also ensure that there are never objectsbetween a person and the seat, e.g. cushions.

Seat belts are only intended to secure andrestrain vehicle occupants. Always observe the"Loading guidelines" for securing objects, lug-gage or loads (Y page 278).


Fastening and adjusting the seat beltsObserve the safety notes on the seat belt(Y page 45) and the notes on correct use of seatbelts (Y page 46).If the center rear seat belt is being used, alsoobserve the information about the seat belt forthe center rear seat (Y page 47).

Regardless of whether the driver's seat belt hasalready been fastened, the 7 seat belt warn-ing lamp lights up for six seconds each time theengine is started. If, after six seconds, the driveror front-passenger seat belt has not been fas-tened and the doors are closed, the 7 seatbelt warning lamp lights up. As soon as the driv-er's and front-passenger seat belts are fastenedor a front door is opened again, the 7 seatbelt warning lamp goes out.If the driver's seat belt is not fastened after theengine is started, an additional warning tone willsound. The warning tone switches off after sixseconds or once the driver's seat belt is fas-tened.If the vehicle's speed exceeds 15 mph(25 km/h) once and the driver's and front-passenger seat belts are not fastened, awarningtone sounds. A warning tone also sounds withincreasing intensity for 60 seconds or until thedriver or front passenger have fastened theirseat belts.If the driver or front passenger unfasten theirseat belts during the journey, the seat belt warn-ing is activated again.

Air bags

IntroductionThe installation point of an air bag can be rec-ognized by the AIR BAG symbol.An air bag complements the correctly fastenedseat belt. It is no substitute for the seat belt. Theair bag provides additional protection in appli-cable accident situations.Not all air bags are deployed in an accident. Thedifferent air bag systems function independ-ently from one another (Y page 55).However, no system available today can com-pletely eliminate injuries and fatalities.It is also not possible to rule out a risk of injurycaused by an air bag due to the high speed atwhich the air bag must be deployed.


G WARNINGIf you do not sit in the correct seat position,the air bag cannot protect as intended andcould even cause additional injury when

deployed. This poses an increased risk ofinjury or even fatal injury.To avoid hazardous situations, always makesure that all of the vehicle's occupants:Rhave fastened their seat belts correctly,including pregnant womenRare sitting correctly andmaintain the great-est possible distance to the air bagsRfollow the following instructionsAlways make sure that there are no objectsbetween the air bag and the vehicle's occu-pants.

RAdjust the seats properly before beginningyour journey. Always make sure that the seatis in an almost upright position. The center ofthe head restraint must support the head atabout eye level.RMove the driver's and front-passenger seatsas far back as possible. The driver's seat posi-tionmust allow the vehicle to be driven safely.ROnly hold the steering wheel on the outside.This allows the air bag to be fully deployed.RAlways lean against the backrest while driv-ing. Do not lean forwards or lean against thedoor or side window. Youmay otherwise be inthe deployment area of the air bags.RAlways keep your feet in the footwell in frontof the seat. Do not put your feet on the dash-board, for example. Your feet may otherwisebe in the deployment area of the air bag.RFor this reason, always secure persons lessthan 5 ft (1.50 m) tall in suitable restraint sys-tems. Up to this height, the seat belt cannotbe worn correctly.

If a child is traveling in your vehicle, alsoobserve the following notes:RAlways secure children under twelve years ofage and less than 5 ft (1.50 m) tall in suitablechild restraint systems.RChild restraint systems should be installed onthe rear seats.ROnly secure a child in a rearward-facing childrestraint system on the front-passenger seatwhen the front-passenger front air bag isdeactivated. If the PASSENGER AIR BAG OFFindicator lamp is permanently lit, the front-


passenger front air bag is deactivated(Y page 44).RAlways observe the instructions and safetynotes on the "Occupant Classification System(OCS)" (Y page 51) and on "Children in thevehicle" (Y page 59) in addition to the childrestraint system manufacturer's installationand operating instructions.

Objects in the vehicle interior may preventan air bag from functioning correctly. Beforestarting your journey and to avoid risks resultingfrom the speed of the air bag as it deploys, makesure that:Rthere are no people, animals or objectsbetween the vehicle occupants and an airbag.Rthere are no objects between the seat, doorand B-pillar.Rno hard objects, e.g. coat hangers, hang onthe grab handles or coat hooks.Rno accessories, such as cup holders, areattached to the vehicle within the deploymentarea of an air bag, e.g. to doors, side windows,rear side trim or side walls.Rno heavy, sharp-edged or fragile objects are inthe pockets of your clothing. Store suchobjects in a suitable place.

G WARNINGIf you modify the air bag cover or affix objectssuch as stickers to it, the air bag can no longerfunction correctly. There is an increased riskof injury.Never modify an air bag cover or affix objectsto it.

G WARNINGSensors to control the air bags are located inthe doors. Modifications or work not per-formed correctly to the doors or door panel-ing, as well as damaged doors, can lead to thefunction of the sensors being impaired. The airbags might therefore not function properlyanymore. Consequently, the air bags cannotprotect vehicle occupants as they aredesigned to do. There is an increased risk ofinjury.Never modify the doors or parts of the doors.Always have work on the doors or door pan-

eling carried out at a qualified specialist work-shop.

Front air bags! Do not place heavy objects on the front-passenger seat. This could cause the systemto identify the seat as being occupied. In theevent of an accident, the restraint systems onthe front-passenger side may be triggeredand have to be replaced.

Driver's air bag: deploys in front of the steer-ing wheel. Front-passenger front air bag;deploys in front of and above the glove box.When deployed, the front air bags offer addi-tional head and thorax protection for the occu-pants in the front seats.The PASSENGER AIR BAG OFF indicator lampinforms you about the status of the front-passenger front air bag (Y page 44).The front-passenger front air bag will onlydeploy if:Rthe system, based on the OCS weight sensorreadings, detects that the front-passengerseat is occupied (Y page 51).

Side impact air bags

G WARNINGUnsuitable seat covers can obstruct or pre-vent deployment of the air bags integratedinto the seats. Consequently, the air bagscannot protect vehicle occupants as they aredesigned to do. In addition, the operation ofthe occupant classification system (OCS)could be adversely affected. This poses anincreased risk of injury or even fatal injury.You should only use seat covers that havebeen approved for the respective seat byMercedes-Benz.

Front side impact air bags: and rear sideimpact air bags; deploy next to the outer bol-ster of the seat backrest.

When deployed, the side impact air bag offersadditional thorax protection. However, it doesnot protect the:RheadRneckRarmsIn the event of a side impact, the side impact airbag is deployed on the side on which the impactoccurs.The side impact air bag on the front-passengerside deploys under the following conditions:Rthe OCS system detects that the front-passenger seat is occupied orRthe seat belt buckle tongue is engaged in thebelt buckle of the front-passenger seat

If the belt tongue is engaged in the belt buckle,the side impact air bag on the front-passengerside deploys if an appropriate accident situationoccurs. In this case, deployment is independentof whether the front-passenger seat is occupiedor not.

Window curtain air bags

Window curtain air bags: are integrated intothe side of the roof frame and deployed in thearea from the A-pillar to the C-pillar.When deployed, the window curtain air bagenhances the level of protection for the head.However, it does not protect the chest or arms.In the event of a side impact, the window curtainair bag is deployed on the side on which theimpact occurs.If the system determines that they can offeradditional protection to that provided by theseat belt, a window curtain air bag may bedeployed in other accident situations(Y page 55).


Occupant Classification System(OCS)

IntroductionThe Occupant Classification System (OCS) cat-egorizes the person in the front-passenger seat.Depending on that result, the front-passengerfront air bag is either enabled or deactivated.The system does not deactivate:Rthe side impact air bagRthe window curtain air bagRthe Emergency Tensioning Devices

RequirementsTo be classified correctly, the front passengermust sit:Rwith the seat belt fastened correctlyRin an almost upright position with their backagainst the seat backrestRwith their feet resting on the floor, if possibleIf the front passenger does not observe theseconditions, OCS may produce a false classifica-tion, e.g. because the front passenger:Rtransfers their weight by supporting them-selves on a vehicle armrestRsits in such a way that their weight is raisedfrom the seat cushion

If it is absolutely necessary to install a childrestraint system on the front-passenger seat, besure to observe the correct positioning of thechild restraint system. Never place objectsunder or behind the child restraint system, e.g. acushion. Fully retract the seat cushion length.The entire base of the child restraint systemmust always rest on the seat cushion of thefront-passenger seat. The backrest of theforward-facing child restraint systemmust lie asflat as possible against the backrest of the front-passenger seat.The child restraint system must not touch theroof or be subjected to a load by the headrestraint. Adjust the angle of the seat backrestand the head restraint position accordingly.Only then can OCS be guaranteed to functioncorrectly. Always observe the child restraint sys-tem manufacturer's installation and operatinginstructions.

G WARNINGIf the PASSENGER AIR BAG OFF indicatorlamp is lit, the front-passenger front air bag isdisabled. It will not be deployed in the event ofan accident and cannot perform its intendedprotective function. A person in the front-passenger seat could then, for example, comeinto contact with the vehicle's interior, espe-cially if the person is sitting too close to thedashboard. This poses an increased risk ofinjury or even fatal injury.When the front-passenger seat is occupied,always ensure that:Rthe classification of the person in the front-passenger seat is correct and the front-passenger front air bag is enabled or disa-bled in accordance with the person in thefront-passenger seatRthe front-passenger seat has been movedback as far back as possible.Rthe person is seated correctly.Make sure, both before and during the jour-ney, that the status of the front-passengerfront air bag is correct.

G WARNINGIf you secure a child in a rearward-facing childrestraint system on the front-passenger seatand the PASSENGER AIR BAG OFF indicatorlamp is off, the front-passenger front air bagmay deploy in the event of an accident. Thechild could be struck by the air bag. This posesan increased risk of injury or even fatal injury.Make sure that the front-passenger front airbag has been disabled. The PASSENGER AIRBAG OFF indicator lamp must be lit.

If the PASSENGER AIR BAG OFF indicator lampstays off, do not install a rearward-facing childrestraint system on the front-passenger seat.You can find more information on OCS under"Problemswith theOccupant Classification Sys-tem" (Y page 54).

G WARNINGIf you secure a child in a forward-facing childrestraint system on the front-passenger seatand you position the front-passenger seat tooclose to the dashboard, in the event of anaccident, the child could:Rcome into contact with the vehicle's inte-rior if the PASSENGER AIR BAG OFF indi-cator lamp is lit, for exampleRbe struck by the air bag if the PASSENGERAIR BAG OFF indicator lamp is off

This poses an increased risk of injury or evenfatal injury.Always move the front-passenger seat as farback as possible and fully retract the seatcushion length. Always make sure that theshoulder belt strap is correctly routed fromthe vehicle belt sash guide to the shoulderbelt guide on the child restraint system. Theshoulder belt strap must be routed forwardsand downwards from the vehicle belt sashguide. If necessary, adjust the vehicle beltsash guide and the front-passenger seataccordingly. Always observe the childrestraint system manufacturer's installationinstructions.

If OCS determines that:Rthe front-passenger seat is unoccupied, thePASSENGER AIR BAG OFF indicator lamplights up after the system self-test andremains lit. This indicates that the front-passenger front air bag is deactivated.Rthe front-passenger seat is occupied by achild of up to twelvemonths old, in a standardchild restraint system, the PASSENGER AIRBAG OFF indicator lamp lights up after thesystem self-test and remains lit. This indi-cates that the front-passenger front air bag isdeactivated.But even in the case of a twelve-month-oldchild, in a standard child restraint system, thePASSENGER AIR BAG OFF indicator lamp cango out after the system self-test. This indi-cates that the front-passenger front air bag isactivated. The result of the classification isdependent on, among other factors, the childrestraint system and the child's stature. It is


recommended that you install the childrestraint system on a suitable rear seat.Rthe front-passenger seat is occupied by a per-son of smaller stature (e.g. a teenager orsmall adult), the PASSENGER AIR BAG OFFindicator lamp lights up and remains lit afterthe system self-test depending on the resultof the classification or, alternatively, goes out.- If the PASSENGER AIR BAG OFF indicatorlamp is off, move the front-passenger seatas far back as possible. Alternatively, a per-son of smaller stature can sit on a rear seat.

- If the PASSENGER AIR BAG OFF indicatorlamp is lit, a person of smaller statureshould not use the front-passenger seat.

Rthe front-passenger seat is occupied by anadult or a person of adult stature, thePASSENGER AIR BAG OFF indicator lampgoes out after the system self-test. This indi-cates that the front-passenger front air bag isactivated.

If children are traveling in the vehicle, be sure toobserve the notes on "Children in the vehicle"(Y page 59).When the occupant classification system (OCS)is malfunctioning, the red 6 restraint systemwarning lamp in the instrument cluster and thePASSENGER AIR BAG OFF indicator lamp lightup simultaneously. The front-passenger front airbag is deactivated in this case and does notdeploy during an accident. Have the OccupantClassification System (OCS) checked andrepaired immediately at a qualified specialistworkshop. Mercedes-Benz recommends thatyou use an authorized Mercedes-Benz Centerfor this purpose.If the front-passenger seat, the seat cover or theseat cushion are damaged, have the necessaryrepair work carried out at a qualified specialistworkshop. Mercedes-Benz recommends thatyou use an authorized Mercedes-Benz Centerfor this purpose.For safety reasons, Mercedes-Benz recom-mends that you only use seat accessories thathave been approved by Mercedes-Benz.If the driver's air bag deploys, this does notmean that the front-passenger front air bag willalso deploy. The Occupant Classification Sys-tem (OCS) categorizes the occupant in the front-passenger seat. Depending on that result, thefront-passenger front air bag is either enabled ordeactivated.

System self-test

G DANGERIf both the PASSENGER AIR BAG OFF andPASSENGER AIR BAG ON indicator lamps donot light up during the system self-test, thesystem is malfunctioning. The front-passenger front air bag might be triggeredunintentionally or might not be triggered at allin the event of an accident with high deceler-ation.

Deployment of Emergency TensioningDevices and air bags


G WARNINGThe air bag parts are hot after an air bag hasbeen deployed. There is a risk of injury.Do not touch the air bag parts. Have adeployed air bag replaced at a qualified spe-cialist workshop as soon as possible.

G WARNINGA deployed air bag no longer offers any pro-tection and cannot provide the intended pro-tection in an accident. There is an increasedrisk of injury.Have the vehicle towed to a qualified special-ist workshop in order to have a deployed airbag replaced.

It is important for your safety and that of yourpassenger to have deployed air bags replaced

and to have any malfunctioning air bagsrepaired. This will help to make sure the air bagscontinue to perform their protective function forthe vehicle occupants in the event of a crash.

G WARNINGEmergency Tensioning Devices that havedeployed pyrotechnically are no longer opera-tional and are unable to perform their inten-ded protective function. This poses anincreased risk of injury or even fatal injury.Have pyrotechnically triggered EmergencyTensioning Devices replaced immediately at aqualified specialist workshop.

An electric motor is used by PRE-SAFE® to trig-ger the tightening of the seat belt in hazardoussituations. This procedure is reversible.If Emergency Tensioning Devices are triggeredor air bags are deployed, you will hear a bang,and a small amount of powder may also bereleased. The 6 restraint system warninglamp lights up.Only in rare cases will the bang affect your hear-ing. The powder that is released generally doesnot constitute a health hazard, but it may causeshort-term breathing difficulties in people withasthma or other respiratory problems. Providedit is safe to do so, you should leave the vehicleimmediately or open the window in order to pre-vent breathing difficulties.Air bags and pyrotechnic Emergency TensioningDevices (ETDs) contain perchlorate material,which may require special handling and regardfor the environment. National guidelines mustbe observed during disposal. In California, seewww.dtsc.ca.gov/HazardousWaste/Perchlorate/index.cfm.

Method of operationDuring the first stage of a collision, the restraintsystem control unit evaluates important physi-cal data relating to vehicle deceleration or accel-eration, such as:RdurationRdirectionRintensityBased on the evaluation of this data, therestraint system control unit triggers the Emer-gency Tensioning Devices during a frontal orrear collision.

An Emergency Tensioning Device can only betriggered, if:Rthe ignition is switched onRthe components of the restraint system areoperational. You can find further informationunder: "Restraint system warning lamp"(Y page 44)Rthe seat belt buckle tongue has engaged inthe belt buckle of the respective front seat

The Emergency Tensioning Devices in the rearcompartment are triggered independently of thelock status of the seat belts.If the restraint system control unit detects amore severe accident, further components ofthe restraint system are activated independ-ently of each other in certain frontal collisionsituations:RFront air bags and driver's knee bagRWindow curtain air bag, if the system deter-mines that deployment can offer additionalprotection to that provided by the seat belt

The front-passenger front air bag is activated ordeactivated depending on the person on thefront-passenger seat. The front-passenger frontair bag can only deploy in an accident if thePASSENGER AIR BAG OFF indicator lamp is off.Observe the information on the PASSENGERAIRBAG indicator lamps (Y page 44).Your vehicle has two-stage front air bags. Duringthe first deployment stage, the front air bag isfilled with propellant gas to reduce the risk ofinjuries. The front air bag is fully deployed withthe maximum amount of propellant gas if a sec-ond deployment threshold is reached within afew milliseconds.The activation threshold of the Emergency Ten-sioning Devices and the air bag are determinedby evaluating the rate of vehicle deceleration oracceleration which occurs at various points inthe vehicle. This process is pre-emptive innature. Deployment should take place in goodtime at the start of the collision.The rate of vehicle deceleration or accelerationand the direction of the force are essentiallydetermined by:Rthe distribution of forces during the collisionRthe collision angleRthe deformation characteristics of the vehicleRthe characteristics of the object with whichthe vehicle has collided

Factors which can only be seen and measuredafter a collision has occurred do not play a deci-


sive role in the deployment of an air bag. Nor dothey provide an indication of air bag deploy-ment.The vehicle can be deformed considerably, with-out an air bag being deployed. This is the case ifonly parts which are relatively easily deformedare affected and the rate of deceleration is nothigh. Conversely, air bagsmay be deployed eventhough the vehicle suffers only minor deforma-tion. This is the case if, for example, very rigidvehicle parts such as longitudinal body mem-bers are hit, and sufficient deceleration occursas a result.If the restraint system control unit detects a sideimpact or if the vehicle rolls over, the applicablecomponents of the restraint system are activa-ted independently of each other depending onthe apparent type of accident.RSide impact air bags on the side where theimpact takes place, independently of theEmergency Tensioning Device and the use ofthe seat belt on the driver's seat and outerseats in the second rowThe side impact air bag on the front-passenger side deploys under the followingconditions:- the OCS system detects that the front-passenger seat is occupied or

Children in the vehicle

Important safety notesAccident statistics show that children securedin the rear seats are safer than children securedin the front-passenger seat. For this reason,Mercedes-Benz strongly advises that you installa child restraint system on a rear seat. Childrenare generally better protected there.If a child younger than twelve years old andunder 5 ft (1.50 m) in height is traveling in thevehicle:Ralways secure the child in a child restraintsystem suitable for Mercedes-Benz vehicles.The child restraint system must be appropri-ate to the age, weight and size of the childRbe sure to observe the instructions and safetynotes in this section in addition to the childrestraint system manufacturer's installationinstructionsRbe sure to observe the instructions and safetynotes on the "Occupant classification system(OCS)" (Y page 51)

G WARNINGIf you leave children unsupervised in the vehi-cle, they could set it inmotion by, for example:Rrelease the parking brake.Rshift the automatic transmission out of theparking position P.Rstart the engine.In addition, they may operate vehicle equip-ment and become trapped. There is a risk ofan accident and injury.When leaving the vehicle, always take theSmartKeywith you and lock the vehicle. Neverleave children unsupervised in the vehicle.

G WARNINGIf persons, particularly children are subjectedto prolonged exposure to extreme heat orcold, there is a risk of injury, possibly evenfatal. Never leave children unattended in thevehicle.

G WARNINGIf the child restraint system is subjected todirect sunlight, parts may get very hot. Chil-

dren may burn themselves on these parts,particularly on the metal parts of the childrestraint system. There is a risk of injury.If you leave the vehicle, taking the child withyou, always ensure that the child restraintsystem is not exposed to direct sunlight. Pro-tect it with a blanket, for example. If the childrestraint system has been exposed to directsunlight, let it cool down before securing thechild in it. Never leave children unattended inthe vehicle.

Always ensure that all vehicle occupants havetheir seat belts fastened correctly and are sittingproperly. Particular attention must be paid tochildren.Observe the safety notes on the seat belt(Y page 45) and the notes on correct use of seatbelts (Y page 46).A booster seat may be necessary to achieveproper seat belt positioning for children over41 lbs (18 kg) until they reach a height where athree-point seat belt can be properly fastenedwithout a booster seat.

Special seat belt retractor

G WARNINGIf the seat belt is released while driving, thechild restraint system will no longer besecured properly. The special seat belt retrac-tor is disabled and the inertia real draws in aportion of the seat belt. The seat belt cannotbe immediately refastened. There is anincreased risk of injury, possibly even fatal.Stop the vehicle immediately, paying atten-tion to road and traffic conditions. Reactivatethe special seat belt retractor and secure thechild restraint system properly.

All seat belts in the vehicle, except the driver'sseat belt, are equipped with a special seat beltretractor. When activated, the special seat beltretractor ensures that the seat belt cannotslacken once the child seat is secured.

64 Driving safety systemsSafety

Important safety notesIf you fail to adapt your driving style or if you areinattentive, the driving safety systems can nei-ther reduce the risk of an accident nor overridethe laws of physics. Driving safety systems aremerely aids designed to assist driving. You areresponsible for maintaining the distance to thevehicle in front, for vehicle speed, for braking ingood time, and for staying in lane. Always adaptyour driving style to suit the prevailing road andweather conditions andmaintain a safe distancefrom the vehicle in front. Drive carefully.The driving safety systems described only workas effectively as possible when there is ade-quate contact between the tires and the roadsurface. Pay particular attention to the informa-tion regarding tires, recommended minimumtire tread depths etc. in the "Wheels and tires"section (Y page 336).In wintry driving conditions, always use wintertires (M+S tires) and if necessary, snow chains.Only in this way will the driving safety systemsdescribed in this section work as effectively aspossible.

ABS (Anti-lock Braking System)

General informationABS regulates brake pressure in such a way thatthe wheels do not lock when you brake. Thisallows you to continue steering the vehiclewhenbraking.The ! ABS warning lamp in the instrumentcluster lights up when the ignition is switchedon. It goes out when the engine is running.ABS works from a speed of about 5 mph(8 km/h), regardless of road-surface conditions.ABS works on slippery surfaces, even when youonly brake gently.

Important safety notesi Observe the "Important safety notes" sec-tion (Y page 65).

G WARNINGIf ABS is faulty, the wheels could lock whenbraking. The steerability and braking charac-teristics may be severely impaired. Addition-ally, further driving safety systems are deac-

tivated. There is an increased danger of skid-ding and accidents.Drive on carefully. Have ABS checked imme-diately at a qualified specialist workshop.

When ABS is malfunctioning, other systems,including driving safety systems, will alsobecome inoperative. Observe the informationon the ABS warning lamp (Y page 259) and dis-play messages which may be shown in theinstrument cluster (Y page 228).

BrakingX If ABS intervenes: continue to depress thebrake pedal vigorously until the braking sit-uation is over.

X To make a full brake application: depressthe brake pedal with full force.

If ABS intervenes when braking, you will feel apulsing in the brake pedal.The pulsating brake pedal can be an indicationof hazardous road conditions, and functions as areminder to take extra care while driving.

BAS (Brake Assist System)

General informationBAS operates in emergency braking situations.If you depress the brake pedal quickly, BASautomatically boosts the braking force, thusshortening the stopping distance.


G WARNINGIf BAS is malfunctioning, the braking distancein an emergency braking situation isincreased. There is a risk of an accident.In an emergency braking situation, depressthe brake pedal with full force. ABS preventsthe wheels from locking.

General informationBAS PLUS can help you to minimize the risk of acollision with a vehicle or a pedestrian andreduce the effects of such a collision. If BASPLUS detects a danger of collision, you areassisted when braking.

i Pay attention to the important safety notesin the "Driving safety systems" section(Y page 65).

BAS PLUS is only available on vehicles with theDriving Assistance package.For BAS PLUS to assist you when driving, theradar sensor system and the camera systemmust be operational.With the help of a sensor system and a camerasystem, BAS PLUS can detect obstacles:Rthat are in the path of your vehicle for anextended period of timeRthat cross the path of your vehicleIn addition, pedestrians in the path of your vehi-cle can be detected.BAS PLUS detects pedestrians by using typicalcharacteristics such as the body contours andposture of a person standing upright.If the radar sensor system or the camera systemis malfunctioning, BAS PLUS functions arerestricted or no longer available. The brake sys-tem is still available with complete brake boost-ing effect and BAS.

i Observe the restrictions described in the"Important safety notes" section(Y page 66).


G WARNINGBAS PLUS cannot always clearly identifyobjects and complex traffic situations.In such cases, BAS PLUS may:Rintervene unnecessarilyRnot interveneThere is a risk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake. Terminate theintervention in a non-critical driving situation.

G WARNINGBAS PLUS cannot always clearly identify peo-ple, this is especially the case if they are mov-ing. BAS PLUS cannot intervene in thesecases. There is a risk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake.

G WARNINGBAS PLUS does not react:Rto small people, e.g. childrenRto animalsRto oncoming vehiclesRwhen corneringAs a result, BAS PLUSmay not intervene in allcritical situations. There is a risk of an acci-dent.Always pay careful attention to the traffic sit-uation and be ready to brake.

In the event of snowfall or heavy rain, the rec-ognition can be impaired.Recognition by the radar sensor system is alsoimpaired if:Rthere is dirt on the sensors or anything elsecovering the sensorsRthere is interference by other radar sourcesRthere are strong radar reflections, for exam-ple in parking garagesRa narrow vehicle is traveling in front, e.g. amotorbike


Ra vehicle is traveling in front on a different lineRvehicles quickly move into the radar sensorsystem detection range

Recognition by the camera system is alsoimpaired in the event of:Rdirt on the camera or if the camera is coveredRglare on the camera system, e.g. from the sunbeing low in the skyRdarknessRor if:

- pedestriansmove quickly, e.g. into the pathof the vehicle

- the camera system no longer recognizes apedestrian as a person due to special cloth-ing or other objects

- a pedestrian is concealed by other objects- the typical outline of a pedestrian is notdistinguishable from the background

Following damage to the front end of the vehicle,have the configuration and operation of theradar sensors checked at a qualified specialistworkshop. This also applies to collisions at slowspeeds where there is no visible damage to thefront of the vehicle.Following damage to the windshield, have theconfiguration and operation of the camera sys-tem checked at a qualified specialist workshop.

FunctionTo avoid a collision, BAS PLUS calculates thebrake force necessary if:Ryou approach an obstacle, andRBAS PLUS has detected a danger of collisionAt speeds of more than20 mph(30 km/h): ifyou depress the brake pedal, BAS PLUS is acti-vated. The increase in brake pressure will becarried out at the last possible moment.At speeds of above20 mph(30 km/h): if youdepress the brake pedal sharply, BAS PLUSautomatically increases the brake pressure to adegree suited to the traffic situation.BAS PLUS provides braking assistance in haz-ardous situations with vehicles in front within aspeed range between 4 mph (7 km/h) and155 mph (250 km/h).

At speeds of up to approximately 44 mph(70 km/h), BAS PLUS can react to:Rstationary objects in the path of your vehicle,e.g. stopped or parked vehiclesRpedestrians in the path of your vehicleRobstacles crossing your path, which move inthe detection range of the sensors and arerecognized by them

i If BAS PLUS demands particularly high brak-ing force, preventative passenger protectionmeasures (PRE-SAFE®) are activated simulta-neously (Y page 57).

X Keep the brake pedal depressed until theemergency braking situation is over.ABS prevents the wheels from locking.

BAS PLUS is deactivated and the brakes func-tion as usual, if:Ryou release the brake pedal.Rthere is no longer a risk of collision.Rno obstacle is detected in front of your vehi-cle.Ryou depress the accelerator pedal.Ryou activate kickdown.

When deactivated, the dis-tance warning function and the autonomousbraking function are also deactivated.If COLLISION PREVENTION ASSIST PLUS isdeactivated, theæ symbol appears in theassistance graphics display.

Distance warning function

General informationThe distance warning function can help you tominimize the risk of a front-end collision with avehicle ahead or reduce the effects of such acollision. If the distance warning functiondetects that there is a risk of a collision, you willbe warned visually and acoustically.

Important safety notesi Observe the "Important safety notes" sec-tion for driving safety systems (Y page 65).

G WARNINGThe distance warning function does not react:Rto people or animalsRto oncoming vehiclesRto crossing trafficRwhen corneringThus, the distance warning function cannotprovide a warning in all critical situations.There is a risk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake.

G WARNINGThe distance warning function cannot alwaysclearly identify objects and complex trafficsituations.In such cases, the distance warning functionmay:Rgive an unnecessary warningRnot give a warningThere is a risk of an accident.Always pay careful attention to the traffic sit-uation and do not rely solely on the distancewarning function.

FunctionStarting at a speed of approximately 4 mph(7 km/h), the distance warning function warnsyou if you are rapidly approaching a vehicle infront. An intermittent warning tone will thensound, and the· distance warning lamp willlight up in the instrument cluster.X Brake immediately in order to increase thedistance from the vehicle in front.

orX Take evasive action, provided it is safe to doso.

Due to the nature of the system, particularlycomplicated but non-critical driving conditionsmay also cause the system to display a warning.With the help of the radar sensor system, thedistance warning function can detect obstaclesthat are in the path of your vehicle for an exten-ded period of time.Up to a speed of approximately 44 mph(70 km/h), the distance warning function can


also react to stationary obstacles, such as stop-ped or parked vehicles.

Autonomous braking functionIf the driver does not react to the distance warn-ing signal in a critical situation, COLLISION PRE-VENTION ASSIST PLUS can assist with theautonomous braking function.Vehicles without DISTRONIC PLUS: theautonomous braking function is available in thefollowing speed ranges:R4–65 mph (7–105 km/h) for moving objectsR4–31mph (7–50 km/h) for stationary objectsVehicles with DISTRONIC PLUS: the autono-mous braking function is available in the follow-ing speed ranges:R4–124mph (7–200 km/h) for moving objectsR4–31mph (7–50 km/h) for stationary objectsDue to the nature of the system, particularlycomplicated but non-critical driving conditionsmay also cause the Autonomous Braking Func-tion to intervene.If the autonomous braking function requires aparticularly high braking force, preventativepassenger protection measures (PRE-SAFE®)are activated simultaneously (Y page 57).

Adaptive Brake Assist

General informationi Observe the "Important safety notes" sec-tion (Y page 65).

With the help of adaptive Brake Assist, the dis-tance warning signal can detect obstacles thatare in the path of your vehicle for an extendedperiod of time.If adaptive Brake Assist detects a risk of colli-sion with the vehicle in front, it calculates thebraking force necessary to avoid a collision. Ifyou apply the brakes forcefully, adaptive BrakeAssist will automatically increase the brakingforce to a level suitable for the traffic conditions.Adaptive Brake Assist provides braking assis-tance in hazardous situations at speeds above4mph (7 km/h). It uses radar sensor technologyto assess the traffic situation.Up to a speed of approximately 155 mph(250 km/h), Adaptive Brake Assist is capable ofreacting to moving objects that have already

been detected as such at least once over theperiod of observation.Up to a speed of approximately 44 mph(70 km/h), Adaptive Brake Assist reacts to sta-tionary obstacles.If adaptive Brake Assist demands particularlyhigh braking force, preventative passenger pro-tection measures (PRE-SAFE®) are activatedsimultaneously (Y page 57).X Keep the brake pedal depressed until theemergency braking situation is over.ABS prevents the wheels from locking.

The brakes will work normally again if:Ryou release the brake pedal.Rthere is no longer any danger of a collision.Rno obstacle is detected in front of your vehi-cle.

Adaptive Brake Assist is then deactivated.

Important safety notesi Observe the "Important safety notes" sec-tion for driving safety systems (Y page 65).

G WARNINGAdaptive Brake Assist cannot always clearlyidentify objects and complex traffic situa-tions.In such cases, Adaptive Brake Assist can:Rintervene unnecessarilyRnot interveneThere is a risk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake. Terminate theintervention in a non-critical driving situation.

G WARNINGAdaptive Brake Assist does not react:Rto people or animalsRto oncoming vehiclesRto crossing trafficRwhen corneringAs a result, the Adaptive Brake Assist may notintervene in all critical conditions.

Due to the nature of the system, particularlycomplicated but non-critical driving conditionsmay also cause Brake Assist to intervene.If adaptive Brake Assist is not available due to amalfunction in the radar sensor system, thebrake system remains available with full brakeboosting effect and BAS.

ESP® (Electronic Stability Program)

General notesi Observe the "Important safety notes" sec-tion (Y page 65).

ESP® monitors driving stability and traction, i.e.power transmission between the tires and theroad surface.If ESP® detects that the vehicle is deviating fromthe direction desired by the driver, one or morewheels are braked to stabilize the vehicle. Theengine output is also modified to keep the vehi-cle on the desired course within physical limits.ESP® assists the driver when pulling away onwet or slippery roads. ESP® can also stabilizethe vehicle during braking.

ETS/4ETS (Electronic Traction System)i Observe the "Important safety notes" sec-tion (Y page 65).

ETS traction control is part of ESP®. On vehicleswith 4MATIC, 4ETS is part of ESP®.Traction control brakes the drive wheels indi-vidually if they spin. This enables you to pullaway and accelerate on slippery surfaces, forexample if the road surface is slippery on oneside. In addition, more drive torque is transfer-red to the wheel or wheels with traction.Traction control remains active, even if youdeactivate ESP®.


G WARNINGIf ESP® is malfunctioning, ESP® is unable tostabilize the vehicle. Additionally, further driv-ing safety systems are deactivated. Thisincreases the risk of skidding and an accident.

Drive on carefully. Have ESP® checked at aqualified specialist workshop.

If the å ESP® OFF warning lamp lights upcontinuously, ESP® is deactivated.If the ÷ ESP® warning lamp lights up contin-uously, ESP® is not available due to a malfunc-tion.Observe the information on warning lamps(Y page 259) and display messages which maybe shown in the instrument cluster(Y page 228).Only use wheels with the recommended tiresizes. Only then will ESP® function properly.

Characteristics of ESP®

ESP® trailer stabilization

General informationIf your vehicle/trailer combination begins toswerve, ESP® assists you in this situation. ESP®slows the vehicle down by braking and limitingthe engine output until the vehicle/trailer com-bination has stabilized.

Important safety notesG WARNINGIf road and weather conditions are poor,trailer stabilization will not be able to preventthe vehicle/trailer combination from swerv-ing. Trailers with a high center of gravity cantip over before ESP® can detect this. There isa risk of an accident.Always adapt your driving style to the prevail-ing road and weather conditions.

If your vehicle with trailer (vehicle/trailer com-bination) begins to lurch, you can only stabilizethe vehicle/trailer combination by depressingthe brake firmly.ESP® trailer stabilization is active above speedsof approximately 40 mph (65 km/h).ESP® trailer stabilization does not work if ESP®is deactivated or malfunctioning.

Crosswind Assist

General informationStrong crosswind gusts can impair the ability ofyour vehicle to drive straight ahead. The cross-wind driving assistance function integrated inESP® noticeably reduces these impairments.ESP® intervenes automatically according to thedirection and intensity of the crosswinds affect-ing your vehicle.ESP® intervenes with stabilizing braking toassist you in keeping the vehicle in the lane.Crosswind Assist is active at vehicle speedsabove 50 mph (80 km/h) when driving straightahead or cornering gently.

Important safety notesCrosswind Assist does not work if ESP® isswitched off or deactivated because of a mal-function.

EBD (electronic brake force distribu-tion)

General informationEBD monitors and controls the brake pressureon the rear wheels to improve driving stabilitywhile braking.


G WARNINGIf EBD is malfunctioning, the rear wheels canlock, e.g. under full braking. This increases therisk of skidding and an accident.You should therefore adapt your driving styleto the different handling characteristics. Havethe brake system checked at a qualified spe-cialist workshop.

Overview of climate control systems

General notesObserve the settings recommended on the fol-lowing pages. The windows could otherwise fogup.To prevent the windows from fogging up:Rswitch off climate control only brieflyRswitch on air-recirculation mode only brieflyRswitch on the cooling with air dehumidifica-tion functionRactivate the "Windshield defrosting" functionbriefly, if required

Climate control regulates the temperature andair humidity in the vehicle interior. The interiorfilter cleans the air, thus improving the interiorclimate.The "Cooling with air dehumidification" functionis only available when the engine is running.Optimum climate control is only achieved withthe side windows and roof closed.If you start the engine using your smartphone,the last selected climate control setting is reac-tivated (Y page 134).

The integrated filter filters out most particles ofdust and soot and completely filters out pollen.It also reduces gaseous pollutants and odors. Aclogged filter reduces the amount of air suppliedto the vehicle interior. For this reason, youshould always observe the interval for replacingthe filter, which is specified in the MaintenanceBooklet. As it depends on environmental condi-tions, e.g. heavy air pollution, the interval maybe shorter than stated in theMaintenance Book-let.

i Ventilate the vehicle for a brief period duringwarm weather, e.g. using the convenienceopening feature (Y page 91). This will speedup the cooling process and the desired inte-rior temperature will be reached morequickly.

i It is possible that the blower may be activa-ted automatically 60minutes after the Smart-Key has been removed depending on variousfactors, e.g. the outside temperature. Thevehicle is then ventilated for 30minutes to drythe automatic climate control.

Notes on breaking-in a new vehicle

Important safety notesThe sensor system of some driving and drivingsafety systems adjusts automatically while acertain distance is being driven after the vehiclehas been delivered or after repairs. Full systemeffectiveness is not reached until the end of thisteach-in procedure.New and replaced brake pads and discs onlyreach their optimum braking effect after severalhundred kilometers of driving. Compensate forthis by applying greater force to the brake pedal.

The first 1000 miles (1500 km)The more you look after the engine when it isnew, the more satisfied you will be with its per-formance in the future.RYou should therefore drive at varying vehicleand engine speeds for the first 1000 miles(1500 km).RAvoid heavy loads, e.g. driving at full throttle,during this period.RWhen changing gears manually, change up ingood time, before the tachometer needle rea-chesÔ of the way to the red area of the tach-ometer.RDo not manually shift to a lower gear to brakethe vehicle.RTry to avoid depressing the accelerator pedalbeyond the pressure point (kickdown).RIdeally, for the first 1,000 miles (1,500 km),drive in program E.

After 1000 miles (1500 km), you can increasethe engine speed gradually and accelerate thevehicle to full speed.You should also observe these notes on break-ing in if the engine or parts of the drive train onyour vehicle have been replaced.Always observe the maximum permissiblespeed.

i Have the DEF tank refilled at a qualified spe-cialist workshop.

Use the special DEF refill bottle when addingDEF betweenmaintenance intervals. Contact anauthorized Mercedes-Benz Center with anyquestions or, if necessary, contact RoadsideAssistance (Y page 29).If the outside temperature is below12‡ (Ò11†)it may be difficult to top up. If DEF is frozen andthere is an active warning indicator, it may notbe possible to add DEF. Park the vehicle in awarmer place, e.g. in a garage, until DEF hasbecome fluid again. It will then be possible toadd DEF again. Alternatively, have the DEF tankrefilled at a qualified specialist workshop.Further information about BlueTEC exhaust gasaftertreatment and DEF is available at anyauthorized Mercedes-Benz Center.

Important safety notesDEF is a water-soluble fluid for the exhaust gasaftertreatment of diesel engines. It is:Rnot poisonousRcolorless and odorlessRnot flammableWhen you open the DEF container, smallamounts of ammonia vapor may be released.Ammonia vapors have a pungent odor and areparticularly irritating to the skin, to mucousmembranes and to the eyes. You may experi-ence a burning sensation in your eyes, nose andthroat. Coughing and watering of the eyes arepossible.Do not inhale ammonia vapors. Fill the DEF tankonly in well-ventilated areas.

DEF must not come into contact with your skin,eyes or clothing and must not be swallowed.Keep DEF away from children.If you or other persons come into contact withDEF, observe the following:RRinse DEF from your skin immediately withsoap and water.RIf DEF comes into contact with your eyes,immediately rinse them thoroughly with cleanwater. Seek medical assistance withoutdelay.RIf DEF has been swallowed, rinse your mouthout immediately. Drink plenty of water. Seekmedical assistance without delay.RChange out of clothing contaminated withDEF immediately.

! Only use DEF in accordance withISO 22241. Do not mix any additives withDEF, and do not dilute DEF with water. Thismay destroy the BlueTEC exhaust gas after-treatment system.

! The vehicle must be parked on level groundto fill the DEF tank. The DEF tank can only befilled as intended with the vehicle parked on alevel surface. This avoids false level readings.Filling the tank is not permitted if the vehicleis not parked on a level surface. There is adanger of overfilling, which could result indamage to components of the BlueTECexhaust gas aftertreatment.

! Rinse surfaces that have come into contactwith DEF immediately with water or removeDEF using a damp cloth and cold water. If theDEF has already crystallized, use a spongeand cold water to clean it. DEF residues crys-tallize after time and contaminate the affec-ted surfaces.

! DEF is not a fuel additive and must not beadded to the fuel tank. If DEF is added to thefuel tank, this can lead to engine damage.

Have the DEF tank refilled at a qualified special-ist workshop. However, you can also refill theDEF tank:Rat a gas station with a DEF filling pumpRwith DEF refill bottlesRwith a DEF refill canisterWhen the pump nozzle switches off automati-cally during filling at a filling pump, the DEF tankhas been completely filled.

Driving tips

General driving tips


G WARNINGIf you switch off the ignition while driving,safety-relevant functions are only availablewith limitations, or not at all. This could affect,for example, the power steering and the brakeboosting effect. You will require considerably

more effort to steer and brake. There is a riskof an accident.Do not switch off the ignition while driving.

G WARNINGIf you operate mobile communication equip-ment while driving, you will be distracted fromtraffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.Only operate this equipment when the vehicleis stationary.

Observe the legal requirements for the countryin which you are driving. Some jurisdictions pro-hibit the driver from using a mobile phone whiledriving a vehicle.If you make a call while driving, always usehands-free mode. Only operate the telephonewhen the traffic situation permits. If you areunsure, pull over to a safe location and stopbefore operating the telephone.Bear in mind that at a speed of only 30 mph(approximately 50 km/h), the vehicle covers adistance of 44 ft (approximately 14 m) per sec-ond.

Drive sensibly – save fuelObserve the following tips to save fuel:X The tires should always be inflated to the rec-ommended tire pressure.

X Remove unnecessary loads.X Remove roof racks when they are not needed.X Warm up the engine at low engine speeds.X Avoid frequent acceleration or braking.X Have all maintenance work carried out asindicated by the service intervals in the Main-tenance Booklet or by the service interval dis-play.

Fuel consumption also increaseswhen driving incold weather, in stop-start traffic and in hilly ter-rain.

affect your reflexes, perceptions and judg-ment.The possibility of a serious or even fatal acci-dent is greatly increased when you drink ortake drugs and drive.Do not drink or take drugs and drive or allowanyone to drive who has been drinking or tak-ing drugs.

Emission control


Certain engine systems are designed to keepthe level of poisonous components in exhaustfumes within legal limits.These systems only work at peak efficiency ifthey are serviced exactly in accordance with themanufacturer's specifications. Always havework on the engine carried out at a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose. In particular, workrelevant to safety or on safety-related systemsmust be carried out at a qualified specialistworkshop.The engine settings must not be changed underany circumstances. Furthermore, all specificservice work must be carried out at regularintervals and in accordance with the Mercedes-Benz service requirements. Details can be foundin the Maintenance Booklet.

The ECO display consists of three sections, withan inner and outer area. The sections corre-spond to the following three categories:

: Acceleration (evaluation of all accel-eration processes):Rthe outer area fills up and the innerarea lights up green: moderateacceleration, especially at higherspeedsRthe outer area empties and theinner area is gray: sporty acceler-ation

; Coasting (evaluation of all decelera-tion processes):Rthe outer area fills up and the innerarea lights up green: anticipatorydriving, keeping your distance andearly release of the accelerator.The vehicle can coast without useof the brakes.Rthe outer area empties and theinner area is gray: frequent heavybraking

= Constant(continuous evaluationover the entire journey):Rthe outer area fills up and the innerarea lights up green: constantspeed and avoidance of unneces-sary acceleration and decelerationRthe outer area empties and theinner area is gray: fluctuations inspeed

The three inner areas display the current drivingstyle and light up green as a result of a particu-larly economical driving style. Depending on thedriving situation, up to two areas may light upsimultaneously.At the beginning of the journey, the three outerareas are empty and fill up as a result of eco-nomical driving. A higher level indicates a moreeconomical driving style. If the three outer areasare completely filled at the same time, the driverhas adopted the most economical driving stylefor the selected settings and prevailing condi-tions. The ECO display border lights up.The ECOdisplay does not indicate the actual fuelconsumption. The additionally achieved rangedisplayed under Bonus fr.

In addition to driving style, the actual consump-tion is affected by other factors, such as:RloadRTire pressureRCold startRChoice of routeRActive electrical consumersThese factors are not included in the ECO dis-play.An economical driving style specially requiresdriving at moderate engine speeds.Achieving a higher value in the categories"Acceleration" and "Constant":Robserve the gearshift recommendationsRdrive using drive program EOn long journeys at a constant speed, e.g. on thehighway, only the outer area for "constant" willchange.The ECO display summarizes the driving stylefrom the start of the journey to its completion.Therefore, there are more marked changes inthe outer areas at the start of a journey. On lon-ger journeys, there are fewer changes. For moremarked changes, perform a manual rest(Y page 214).For further information on the ECO display, see(Y page 213).

Braking


G WARNINGIf you shift down on a slippery road surface inan attempt to increase the engine's brakingeffect, the drive wheels could lose their grip.There is an increased danger of skidding andaccidents.Do not shift down for additional engine brak-ing on a slippery road surface.

Downhill gradients! On long and steep gradients, you mustreduce the load on the brakes by shifting to alower gear in good time. This allows you totake advantage of the engine's braking effect.This helps you to avoid overheating thebrakes and wearing them out excessively.

Driving tips 159

Drivingandparking

Z

When you take advantage of engine braking, adrive wheel may not turn for some time, e.g.on a slippery road surface. This could causedamage to the drive train. This type of damageis not covered by the Mercedes-Benz war-ranty.

Heavy and light loads

G WARNINGIf you rest your foot on the brake pedal whiledriving, the braking system can overheat. Thisincreases the stopping distance and can evencause the braking system to fail. There is arisk of an accident.Never use the brake pedal as a footrest. Neverdepress the brake pedal and the acceleratorpedal at the same time.

! Depressing the brake pedal constantlyresults in excessive and premature wear tothe brake pads.

If the brakes have been subjected to a heavyload, do not stop the vehicle immediately. Driveon for a short while. This allows the airflow tocool the brakes more quickly.

Wet roadsIf you have driven for a long time in heavy rainwithout braking, there may be a delayed reac-tion from the brakes when braking for the firsttime. This may also occur after the vehicle hasbeen washed or driven through deep water.You have to depress the brake pedal morefirmly. Maintain a greater distance from thevehicle in front.After driving on a wet road or having the vehiclewashed, brake firmly while paying attention tothe traffic conditions. This will warm up thebrake discs, thereby drying them more quicklyand protecting them against corrosion.

Limited braking performance on salt-treated roadsIf you drive on salted roads, a layer of salt resi-due may form on the brake discs and brakepads. This can result in a significantly longerbraking distance.

RIn order to prevent any salt build-up, apply thebrakes occasionally while paying attention tothe traffic conditions.RCarefully depress the brake pedal and thebeginning and end of a journey.RMaintain a greater distance to the vehicleahead.

Servicing the brakes! The brake fluid level may be too low, if:Rif the red brake warning lamp lights up inthe instrument cluster andRyou hear a warning tone while the engine isrunning

Observe additional warning messages in themultifunction display.The brake fluid level may be too low due tobrake pad wear or leaking brake lines.Have the brake system checked immediately.Consult a qualified specialist workshop toarrange this.

! Vehicles with 4MATIC: function or per-formance testsmay only be carried out on a 2-axle dynamometer. If you wish to operate thevehicle on such a dynamometer, please con-sult a qualified specialist workshop inadvance. You could otherwise damage thedrive train or the brake system.

! Vehicles with 4MATIC: the ESP® systemoperates automatically. If the electric parkingbrake is tested on a brake dynamometer, theengine and ignitionmust be switched off: turnthe SmartKey in the ignition lock to positionu or1 or press the Start/Stop buttonrepeatedly in accordance with the givenSmartKey positions.Braking triggered automatically by ESP® maycause severe damage to the brake system.

All checks and maintenance work on the brakesystem must be carried out at a qualified spe-cialist workshop.Have brake pads installed and brake fluidreplaced at a qualified specialist workshop.If the brake system has only been subject tomoderate loads, you should test the functional-ity of your brakes at regular intervals.Information on BAS (Brake Assist) (Y page 65)and BAS PLUS (Brake Assist PLUS) (Y page 66).

For safety reasons, Mercedes-Benz recom-mends only installing the following brake disksand brake pads/linings:Rbrake disks that have been approved byMercedes-BenzRbrake pads/linings that have been approvedbyMercedes-Benz or that are of an equivalentstandard of quality

Other brake disks or brake pads/linings cancompromise the safety of your vehicle.Always replace all brake disks and brake pads/linings on an axle at the same time. Alwaysinstall new brake pads/linings when replacingbrake disks.The vehicle is equipped with lightweight brakedisks to which the wheel assembly with rim andthreaded connection is matched.The use of brake disks other than thoseapproved by Mercedes-Benz can change thetrack width and is subject to approval, if appli-cable.Shock-type loads when handling the brakediscs, such as when changing wheels, can leadto a reduction in comfort when driving with light-weight brake discs. Avoid shock-type loads onthe lightweight brake disks, particularly on thebrake plate.Mercedes-Benz recommends that you only usebrake fluid that has been specially approved foryour vehicle by Mercedes-Benz, or which corre-sponds to an equivalent quality standard. Brakefluid which has not been approved forMercedes-Benz vehicles or which is not of anequivalent quality could affect your vehicle'soperating safety.

Driving on wet roads

HydroplaningIf water has accumulated to a certain depth onthe road surface, there is a danger of hydro-planing occurring, even if:Ryou drive at low speedsRthe tires have adequate tread depthFor this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:Rlower your speedRavoid ruts

Ravoid sudden steering movementsRbrake carefully

Driving on flooded roads! Bear in mind that vehicles traveling in frontor in the opposite direction createwaves. Thismay cause the maximum permissible waterdepth to be exceeded.Failure to observe these notes may result indamage to the engine, electrical systems andtransmission.

If you have to drive on stretches of road onwhichwater has collected, please bear in mind that:Rin the case of standing water, the water levelmay be no higher than the lower edge of thevehicle bodyRyou should drive no faster than walking pace

Winter driving

G WARNINGIf you shift down on a slippery road surface inan attempt to increase the engine's brakingeffect, the drive wheels could lose their grip.There is an increased danger of skidding andaccidents.Do not shift down for additional engine brak-ing on a slippery road surface.

G DANGERIf the exhaust pipe is blocked or adequateventilation is not possible, poisonous gasessuch as carbon monoxide (CO) may enter thevehicle. This is the case, e.g. if the vehiclebecomes trapped in snow.

Cruise control

General notesCruise control maintains a constant road speedfor you. It brakes automatically in order to avoidexceeding the set speed. Change into a lower

gear in good time on long and steep downhillgradients. This is especially important if thevehicle is laden or towing a trailer. By doing so,you will make use of the braking effect of theengine. This relieves the load on the brake sys-tem and prevents the brakes from overheatingand wearing too quickly.Use cruise control only if road and traffic con-ditions make it appropriate to maintain a steadyspeed for a prolonged period. You can store anyroad speed above 20 mph (30 km/h).

Important safety notesCruise control can neither reduce the risk of anaccident if you fail to adapt your driving style noroverride the laws of physics. Cruise control can-not take into account the road, traffic andweather conditions. Cruise control is only anaid. You are responsible for maintaining a safedistance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inlane.Do not use cruise control:Rin road and traffic conditions which do notallow you tomaintain a constant speed, e.g. inheavy traffic or on winding roadsRon slippery road surfaces. Braking or accel-erating could cause the drive wheels to losetraction and the vehicle could then skidRwhen there is poor visibility, e.g. due to fog,heavy rain or snow

If there is a change of drivers, advise the newdriver of the speed stored.

DISTRONIC PLUS

General notesDISTRONIC PLUS regulates the speed and auto-matically helps you maintain the distance fromthe vehicle detected in front. Vehicles are detec-ted with the aid of the radar sensor system.DISTRONIC PLUS brakes automatically so thatthe set speed is not exceeded.Change into a lower gear in good time on longand steep downhill gradients. This is especiallyimportant if the vehicle is laden. By doing so, youwill make use of the braking effect of the engine.This relieves the load on the brake system andprevents the brakes from overheating and wear-ing too quickly.If DISTRONIC PLUS detects that there is a risk ofa collision, you will be warned visually andacoustically. DISTRONIC PLUS cannot prevent acollision without your intervention. An intermit-tent warning tone will then sound and the dis-tance warning lamp will light up in the instru-ment cluster. Brake immediately in order toincrease the distance to the vehicle in front ortake evasive action provided it is safe to do so.DISTRONIC PLUS operates in the speed rangebetween 0 mph (0 km/h) and 120 mph(200 km/h).Do not use DISTRONIC PLUS while driving onroads with steep gradients.As DISTRONIC PLUS transmits radar waves, itcan resemble the radar detectors of the respon-sible authorities.

Activating at the current speed/laststored speedG WARNINGIf you call up the stored speed and it differsfrom the current speed, the vehicle acceler-ates or decelerates. If you do not know thestored speed, the vehicle could accelerate orbrake unexpectedly. There is a risk of an acci-dent.Pay attention to the road and traffic condi-tions before calling up the stored speed. If youdo not know the stored speed, store thedesired speed again.


X Remove your foot from the accelerator pedal.DISTRONIC PLUS is activated. The first time itis activated, the current speed is stored. Oth-

erwise, it sets the vehicle speed to the previ-ously stored value.

Driving with DISTRONIC PLUS

Pulling away and drivingX If you want to pull away with DISTRONICPLUS: remove your foot from the brake pedal.


orX Accelerate briefly.The vehicle pulls away and adapts its speed tothat of the vehicle in front. If no vehicle isdetected in front, your vehicle accelerates tothe stored speed.

The vehicle can also pull away when it is facingan unidentified obstacle or is driving on a differ-ent line from another vehicle. The vehicle thenbrakes automatically.If DISTRONIC PLUS does not detect a vehicle infront, the system operates like a cruise control.If DISTRONIC PLUS detects that the vehicle infront is driving slower, your vehicle brakes. Inthis way, the specified minimum distance youhave selected is maintained.If DISTRONIC PLUS detects that the vehicle infront is driving faster, your vehicle acceleratesto the stored speed.

Selects the drive programDISTRONIC PLUS supports a sporty driving stylewhen you have selected the S or S+ driving pro-gram (Y page 144). Acceleration behind thevehicle in front or to the set speed is then notice-ablymore dynamic. If you have selected theC orE driving program, the vehicle accelerates moregently. This setting is recommended in stop-and-start traffic.

Changing lanesDISTRONIC PLUS aids you when switching tothe overtaking lane, if:Ryou are driving faster than 45 mph (70 km/h)Ryou switch on the appropriate turn signalRDISTRONIC PLUS does not currently detect adanger of a collision

If these conditions are fulfilled, your vehicle isaccelerated. Acceleration will be interrupted ifchanging lanes takes too long or if the distance


between your vehicle and the vehicle in frontbecomes too small.When you change lanes, DISTRONIC PLUSmon-itors the left lane (on left-hand-drive vehicles) orthe right lane (on right-hand-drive vehicles).

StoppingG WARNINGWhen leaving the vehicle, even if it is brakedonly by DISTRONIC PLUS, it could roll away if:Rthere is a malfunction in the system or inthe voltage supply.RDISTRONIC PLUS has been deactivatedwith the cruise control lever, e.g. by a vehi-cle occupant or from outside the vehicle.Rthe electrical system in the engine com-partment, the battery or the fuses havebeen tampered with.Rthe battery is disconnected.Rthe accelerator pedal has been depressed,e.g. by a vehicle occupant.

There is a risk of an accident.If you wish to exit the vehicle, always turn offDISTRONIC PLUS and secure the vehicleagainst rolling away.

For further information on deactivatingDISTRONIC PLUS (Y page 169).If DISTRONIC PLUS detects that the vehicle infront has stopped, it will cause your vehicle tobrake and come to a halt.Once your vehicle is stationary, it remains sta-tionary and you do not need to depress thebrake.After a time, the electric parking brake securesthe vehicle and relieves the service brake.Depending on the specified minimum distance,your vehicle will come to a standstill at a suffi-cient distance behind the vehicle in front. Thespecified minimum distance is set using thecontrol on the cruise control lever.

When DISTRONIC PLUS is activated, the trans-mission is shifted automatically to positionj,if:Rthe driver's seat belt is not fastened and thedriver's door is open.Rthe engine is switched off, unless it is auto-matically switched off by the ECO start/stopfunction.

The electric parking brake secures the vehicleautomatically if DISTRONIC PLUS is activatedwhen the vehicle is stationary and:Ra system malfunction occurs.Rthe power supply is insufficient.If a malfunction occurs, the transmission mayalso be shifted to positionj automatically.

Setting a speedX Push the cruise control lever up: for ahigher speed or down; for a lower speed.

X To adjust the set speed in 1 mph incre-ments (1 km/h increments): briefly pushthe cruise control lever up: or down; tothe pressure point.Every time the cruise control lever is pressedup: or down; the last speed stored isincreased or reduced.

X To adjust the set speed in 5 mph incre-ments (10 km/h increments): briefly pushthe cruise control lever up: or down;beyond the pressure point.Every time the cruise control lever is pressedup: or down;, the last speed stored isincreased or reduced.

i If you accelerate to overtake, DISTRONICPLUS adjusts the vehicle's speed back to thelast speed stored after you have finished over-taking.

Setting a specified minimum distanceYou can set the specified minimum distance forDISTRONIC PLUS by varying the time spanbetween one and two seconds. With this func-tion, you can set the minimum distance thatDISTRONIC PLUS maintains to the vehicle infront, depending on the driving speed. You cansee this distance in the multifunction display(Y page 168).Make sure that you maintain the minimum dis-tance to the vehicle in front as required by law.

Tips for driving with DISTRONIC PLUS

General notesPay particular attention in the following trafficsituations:RCornering, entering and exiting a bend: theability of DISTRONIC PLUS to detect vehicleswhen cornering is limited. Your vehicle maybrake unexpectedly or late.RDriving on a different line: DISTRONIC PLUSmay not detect vehicles which are not drivingin the middle of their lane. The distance to thevehicle in front will be too short.ROther vehicles changing lane: DISTRONICPLUS has not detected the vehicle cutting inyet. The distance to this vehicle will be tooshort.RNarrow vehicles: DISTRONIC PLUS does notdetect the vehicle in front on the edge of theroad because of its narrow width. The dis-tance to the vehicle in front will be too short.RObstacles and stationary vehicles:DISTRONIC PLUS does not brake for obsta-cles or stationary vehicles. If, for example, thedetected vehicle turns a corner and reveals anobstacle or stationary vehicle, DISTRONICPLUS will not brake for these.RCrossing vehicles: DISTRONIC PLUSmaymis-takenly detect vehicles that are crossing yourlane. Activating DISTRONIC PLUS at trafficlights with crossing traffic, for example, couldcause your vehicle to pull away unintention-ally.

In such situations, brake if necessary.DISTRONIC PLUS is then deactivated.

DISTRONIC PLUS with Steering Assist andStop&Go Pilot helps you keep the vehicle in thecenter of the lane by means of moderate steer-ing interventions in a speed range from0–125 mph (0–200 km/h).It monitors the area in front of your vehicle bymeans of multifunction camera:, at the top ofthe windshield.In a speed range from 0 - 37 mph (0 - 60 km/h),Stop&Go Pilot focuses on the vehicle in front,taking into account lane markings, e.g. whenyou are following vehicles in a traffic jam.At speeds of more than 37 mph (60 km/h),Steering Assist focuses on clear lane markings(left and right), only focusing on the vehicle infront if clear lane markings are not present.If these conditions are not present, SteeringAssist and Stop&Go Pilot cannot provide assis-tance.DISTRONIC PLUSmust be active in order for thefunction to be available.

Important safety notesIf you fail to adapt your driving style, DISTRONICPLUS with Steering Assist and Stop&Go Pilotcan neither reduce the risk of an accident noroverride the laws of physics. It cannot takeaccount of road, weather and traffic conditions.DISTRONIC PLUS with Steering Assist andStop&Go Pilot is only an aid. You are responsiblefor maintaining a safe distance to the vehicle infront, for vehicle speed, for braking in good timeand for staying in lane.DISTRONIC PLUS with Steering Assist andStop&Go Pilot does not detect road and trafficconditions and does not detect all road users. Ifyou are following a vehicle which is drivingtowards the edge of the road, your vehicle couldcome into contact with the curb or other roadboundaries. Be particularly aware of other roadusers, e.g. cyclists, that are directly next to yourvehicle.Obstacles such as traffic pylons on the lane orprojecting out into the lane are not detected.An inappropriate steering intervention, e.g. afterintentionally driving over a lane marking, can becorrected at any time if you steer slightly in theopposite direction.DISTRONIC PLUS with Steering Assist andStop&Go Pilot cannot continuously keep yourvehicle in lane. In some cases, steering inter-vention is not sufficient to bring the vehicle backto the lane. In such cases, you must steer the

vehicle yourself to ensure that it does not leavethe lane.The systemmay be impaired ormay not functionif:Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or sprayRthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)Rthewindshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the cameraRthere are no, several or unclear lanemarkingsfor a lane, e.g. in areas with road constructionworkRthe lanemarkings are worn away, dark or cov-ered up, e.g. by dirt or snowRthe distance to the vehicle in front is too smalland the lane markings thus cannot be detec-tedRthe lane markings change quickly, e.g. lanesbranch off, cross one another or mergeRthe road is narrow and windingRthere are highly variable shade conditions onthe roadway

Active Parking Assist

General notesActive Parking Assist is an electronic parking aidwith ultrasound. It measures the road on bothsides of the vehicle. A parking symbol indicatesa suitable parking space. Active steering inter-vention and brake application can assist youduring parking and when exiting a parkingspace. You may also use PARKTRONIC(Y page 175).

Important safety notesActive Parking Assist is merely an aid. It is not areplacement for your attention to your immedi-ate surroundings. You are always responsiblefor safe maneuvering, parking and exiting aparking space. Make sure that no persons, ani-mals or objects are in the maneuvering range.When PARKTRONIC is switched off, Active Park-ing Assist is also unavailable.For vehicles with a trailer tow hitch installed, theminimum length for parking spaces is slightlylonger.If you have attached a trailer to your vehicle, youshould not use Active Parking Assist. Once theelectrical connection is established between

your vehicle and the trailer, Active ParkingAssist is no longer available. PARKTRONIC isdeactivated for the rear area.

G WARNINGWhile parking or pulling out of a parkingspace, the vehicle swings out and can driveonto areas of the oncoming lane. This couldresult in a collision with another road user.There is a risk of an accident.Pay attention to other road users. Stop thevehicle if necessary or cancel the Active Park-ing Assist parking procedure.

! If unavoidable, you should drive over obsta-cles such as curbs slowly and not at a sharpangle. Otherwise, you may damage thewheels or tires.

Active Parking Assist may possibly indicateparking spaces which are not suitable for park-ing, for example:Rwhere parking or stopping is prohibitedRin front of driveways or entrances and exitsRon unsuitable surfaces


Parking tips:ROn narrow roads, drive as close to the parkingspace as possible.RParking spaces that are littered or overgrownmight be identified or measured incorrectly.RParking spaces that are partially occupied bytrailer drawbars might not be identified assuch or be measured incorrectly.RSnowfall or heavy rain may lead to a parkingspace being measured inaccurately.RPay attention to the PARKTRONIC(Y page 177) warning messages during theparking procedure.RYou can intervene in the steering procedureto correct it at any time. Active Parking Assistis then deactivated.RWhen transporting a load which protrudesfrom your vehicle, you should not use ActiveParking Assist.RNever use Active Parking Assist when snowchains are installed.RAlways pay attention to the specified tirepressure for your vehicle. This has a directinfluence on the parking characteristics of thevehicle.

Use Active Parking Assist for parking spaces:Rparallel or at right angles to the direction oftravelRon straight roads, not bendsRon the same level as the road, e.g. not on thepavement

Detecting parking spacesObjects located above the height range of ActiveParking Assist will not be detected when theparking space is measured. These are not takeninto account when the parking procedure is cal-culated, e.g. overhanging loads, truck over-hangs or loading ramps.

G WARNINGIf there are objects above the detection range:RActive Park Assist may steer too earlyRthe vehicle may not stop in front of theseobjects

You may cause a collision as a result. There isa risk of an accident.

If objects are located above the detectionrange, stop and deactivate Active ParkingAssist.

For further information on the detection range(Y page 176).Active Parking Assist does not assist you park-ing in spaces at right angles to the direction oftravel if:Rtwo parking spaces are located directly nextto one anotherRthe parking space is directly next to a lowobstacle such as a low curbRyou forward-parkActive Parking Assist does not assist you park-ing in spaces that are parallel or at right anglesto the direction of travel if:Rthe parking space is on a curbRthe system reads the parking space as beingblocked, for example by foliage or grass pav-ing blocksRthe area is too small for the vehicle to maneu-ver intoRthe parking space is bordered by an obstacle,e.g. a tree, a post or a trailer

: Detected parking space on the left; Parking symbol= Detected parking space on the rightActive Parking Assist is switched on automati-cally when driving forwards. The system isoperational at speeds of up to approximately22 mph (35 km/h). While in operation, the sys-tem independently locates and measures park-ing spaces on both sides of the vehicle.

Active Parking Assist will only detect parkingspaces:Rparallel or at right angles to the direction oftravelRthat are parallel to the direction of travel andat least 59 in (1.5 m) wideRthat are parallel to the direction of travel andat least 39.5 in (1.0 m) longer than your vehi-cleRat right angles to the direction of travel and atleast 39.5 in (1.0 m) wider than your vehicle

i Note that Active Parking Assist cannotmeasure the size of a parking space if it is atright angles to the direction of travel. You willneed to judge whether your vehicle will fit intothe parking space.

When driving at speeds below 19 mph(30 km/h), you will see parking symbol; as astatus indicator in the instrument cluster. Whena parking space has been detected, an arrowtowards the right or the left also appears. Bydefault, Active Parking Assist only displays park-ing spaces on the front-passenger side. Parkingspaces on the driver's side are displayed assoon as the turn signal on the driver's side isactivated. When parking on the driver's side,this must remain switched on until you acknowl-edge the use of Active Parking Assist by press-ing thea button on the multifunction steer-ing wheel. The system automatically determineswhether the parking space is parallel or at rightangles to the direction of travel.A parking space is displayed while you are driv-ing past it, and until you are approximately 50 ft(15 m) away from it.

ATTENTION ASSIST

General notesATTENTION ASSIST helps you during long,monotonous journeys, such as on highways. It isactive in the 37 mph (60 km/h) to 124 mph(200 km/h) speed range. If ATTENTION ASSISTdetects typical indicators of fatigue or increas-ing lapses in concentration on the part of thedriver, it suggests taking a break.

Important safety notesATTENTION ASSIST is only an aid to the driver. Itmight not always recognize fatigue or increasinginattentiveness in time or fail to recognize themat all. The system is not a substitute for a well-rested and attentive driver.The functionality of ATTENTION ASSIST isrestricted and warnings may be delayed or notoccur at all:Rif the length of the journey is less than approx-imately 30 minutesRif the road condition is poor, e.g. if the surfaceis uneven or if there are potholesRif there is a strong side windRif you have adopted a sporty driving style withhigh cornering speeds or high rates of accel-erationRif you are predominantly driving at a speedbelow 37 mph (60 km/h) or above 124 mph(200 km/h)Rif you are drivingwith DISTRONIC PLUSSteer-ing Assist activatedRif the time has been set incorrectlyRin active driving situations, such as when youchange lanes or change your speed

Displaying the attention level

In the Assistance menu (Y page 220) of the on-board computer, you can call up the current sta-tus information.X Select the Assistance display for ATTENTIONASSIST using the on-board computer(Y page 219).

The following information appears:Rthe length of the journey since the last break.Rthe attention level determined by ATTENTIONASSIST (Attention Level), displayed in abar display in five levels from high to low.Rif ATTENTION ASSIST is unable to calculatethe attention level and cannot issue a warn-ing, the System Suspended messageappears. The bar display then changes thedisplay, e.g. if you are driving at a speed below37 mph (60 km/h) or above 124 mph(200 km/h).

Activating ATTENTION ASSISTX Activate ATTENTION ASSIST using the on-board computer (Y page 221).The system determines the attention level ofthe driver depending on the setting selected:

Selection Standard: the sensitivity with whichthe system determines the attention level is setto normal.Selection Sensitive: the sensitivity is sethigher. The attention level detected by AttentionAssist is adapted accordingly and the driver iswarned earlier.When ATTENTION ASSIST is deactivated, theé symbol appears in the multifunction dis-play in the assistance graphic display.WhenATTENTIONASSIST has been deactivated,it is automatically reactivated after the enginehas been stopped. The sensitivity selected cor-

responds to the last selection activated (stand-ard/sensitive).

Warning in the multifunction displayIf fatigue or increasing lapses in concentrationare detected, a warning appears in the multi-function display: ATTENTION ASSIST Take aBreak!.In addition to the message shown in the multi-function display, you will then hear a warningtone.X If necessary, take a break.X Confirm the message by pressing theabutton on the steering wheel.

On long journeys, take regular breaks in goodtime to allow yourself to rest properly. If you donot take a break and ATTENTION ASSIST con-tinues to detect increasing lapses in concentra-tion, you will be warned again after 15 minutesat the earliest. This will only happen if ATTEN-TION ASSIST still detects typical indicators offatigue or increasing lapses in concentration.Vehicles with COMANDmultimedia system:if a warning appears in themultifunction display,a service station search is performed in the mul-timedia system. You can select a service stationand navigation to this service station will thenbegin. This function can be activated and deac-tivated in the COMANDmultimedia system (seethe Digital Operator's Manual).

Traffic Sign Assist

General notesTraffic Sign Assist displays the maximum speedpermitted to the driver in the instrument cluster.The data and general traffic regulations stored inthe navigation system are used to determine thecurrent speed limit.Traffic Sign Assist is a map-based system, andfor this reason, traffic signs put up temporarily(e.g. near roadworks) are not detected. There isalso no display for changing traffic signs.Traffic signs with a restriction indicated by anadditional sign (e.g. in wet conditions) are alsoshown.


The sign indicating the end of a restriction onlyappears with the restriction in the instrumentcluster when:RThe regulation must be observed with therestriction, orRTraffic Sign Assist is unable to determinewhether the restriction applies

If Traffic Sign Assist is unable to determine amaximumpermitted speed fromany of the avail-able sources, no speed limit appears in theinstrument cluster either.

Traffic Sign Assist is not available in all coun-tries. In this case, display: appears in theassistance graphic (Y page 219).

Important safety notesTraffic SignAssist is only an aid and is not alwaysable to correctly display speed limits. Trafficsigns always have priority over the Traffic SignAssist display.The system may be either functionally impairedor temporarily unavailable if the information inthe digital streetmap of the navigation system isincorrect or out of date.

General notesThe Lane Tracking package consists of BlindSpot Assist (Y page 193) and Lane KeepingAssist (Y page 195).

Blind Spot Assist

General notesBlind Spot Assist monitors the areas on eitherside of the vehicle that are not visible to thedriver with two lateral, rear-facing radar sen-sors. A warning lamp lights up in the exteriormirrors and draws your attention to vehiclesdetected in the monitored area. If you thenswitch on the corresponding turn signal tochange lane, you will also receive an optical andaudible warning.Blind Spot Assist supports you from a speed ofapproximately 20 mph (30 km/h).

Active Blind Spot Assist

General notesActive Blind Spot Assist uses a radar sensorsystem, pointed toward the rear of the vehicle,to monitor the area to the sides of the vehiclewhich the driver is unable to see. Awarning lamp

lights up in the exterior mirrors and draws yourattention to vehicles detected in the monitoredarea. If you then switch on the correspondingturn signal to change lane, you will also receivean optical and audible warning. If a risk of lateralcollision is detected, corrective braking mayhelp you avoid a collision. Before a course-cor-recting brake application, Active Blind SpotAssist evaluates the space in the direction oftravel and at the sides of the vehicle. For this,Active Blind Spot Assist uses the forward-facingradar sensors.Active Blind Spot Assist supports you from aspeed of approximately 20 mph (30 km/h).

Important safety notesActive Blind Spot Assist is only an aid and is nota substitute for attentive driving.

G WARNINGActive Blind Spot Assist does not react to:Rvehicles overtaken too closely on the side,placing them in the blind spot areaRvehicles which approach with a large speeddifferential and overtake your vehicle

As a result, Active Blind Spot Assist may nei-ther give warnings nor intervene in such sit-uations. There is a risk of an accident.Always observe the traffic conditions care-fully, and maintain a safe lateral distance.

This can be accomplished by checking the trailerlighting.

Towing a trailer


G WARNINGInstalling an unsuitable ball coupling mayresult in overloading of the trailer tow hitchand the rear axle. This applies especially if theball coupling in question is longer or angleddifferently. This could seriously impair thedriving characteristics and the trailer cancome loose. There is a risk of an accident.You should only ever install a ball couplingthat has the permissible dimensions and thatis designed to meet your trailer-towingrequirements. Do not modify the ball couplingor the trailer tow hitch.

You will find the values approved by the manu-facturer on the vehicle identification plates andthose for the towing vehicle under "Technicaldata" (Y page 371).

G WARNINGWhen the vehicle/trailer combination beginsto lurch, you could lose control of it. The vehi-cle/trailer combination could even rollover.There is a risk of an accident.On no account should you attempt tostraighten up the vehicle/trailer combinationby increasing the speed. Reduce vehiclespeed and do not countersteer. Apply thebrake as necessary.

! If you have a trailer tow hitch retrofitted,changes to the engine cooling systemmay benecessary, depending on the vehicle type.If you have a trailer tow hitch retrofitted,observe the anchorage points on the chassisframe.

The installation of a trailer tow hitch is only per-missible if a towing weight is specified in yourvehicle documents. If this is not the case, thenthe vehicle is not approved for the towing of atrailer.

202 Towing a trailerDrivingandparking

For more information, please contact a qualifiedspecialist workshop.Please observe the manufacturer's operatinginstructions for the trailer coupling if a detach-able trailer coupling is used.Couple and uncouple the trailer carefully. If youdo not couple the trailer to the towing vehiclecorrectly, the trailer could become detached.Make sure that the following values are notexceeded:Rthe permissible trailer drawbar noseweightRthe permissible trailer loadRthe permissible rear axle load of the towingvehicleRthe maximum permissible gross vehicleweight of both the towing vehicle and thetrailer

The applicable permissible values, which mustnot be exceeded, can be found:Rin the vehicle documentsRon the type plate for the trailerRon the vehicle identification plateIf the values differ, the lowest value applies.When towing a trailer, your vehicle's handlingcharacteristics will be different in comparisonwith when driving without a trailer.The vehicle/trailer combination:Ris heavierRis restricted in its acceleration and gradient-climbing capabilityRhas an increased braking distanceRis affected more by strong crosswindsRdemands more sensitive steeringRhas a larger turning circleThis could impair the handling characteristics.When towing a trailer, always adjust your speedto the current road and weather conditions. Donot exceed the maximum permissible speed foryour vehicle/trailer combination.

Notes on towing a trailer

General notesRDo not exceed the maximum permissiblespeed for vehicle/trailer combinations in therelevant country.

This lowers the risk of an accident.ROnly install an approved trailer coupling onyour vehicle.Further information on availability and oninstallation is available from any authorizedMercedes-Benz Center.RThe bumpers of your vehicle are not suitablefor installing detachable trailer couplings.RDo not install hired trailer couplings or otherdetachable trailer couplings on the bumpersof your vehicle.RIf you no longer need the ball coupling,remove it from the ball coupling recess. Thiswill reduce the risk of damage to the ball cou-pling.

When towing a trailer, set the tire pressure onthe rear axle of the towing vehicle for a maxi-mum load; see the tire pressure table in the fuelfiller flap (Y page 354).Please note that when towing a trailer, the fol-lowing driving systems have limited availabilityor are not available at all:RPARKTRONIC (Y page 175)RBlind Spot Assist (Y page 193)RActive Lane Keeping Assist (Y page 200)On vehicles without level control, the height ofthe ball coupling will alter according to the loadplaced on the vehicle. If necessary, use a trailerwith a height-adjustable drawbar.You will find permissible trailer loads under"Technical data" (Y page 371).

Driving tipsObserve the information on ESP® trailer stabili-zation (Y page 73) and on pulling away with atrailer (Y page 135).The maximum permissible speed for vehicle/trailer combinations depends on the type oftrailer. Before beginning the journey, check thetrailer's documents to see what the maximumpermitted speed is. Observe the maximum per-missible speed in the relevant country.For certain Mercedes-Benz vehicles, the maxi-mum permissible rear axle load is increasedwhen towing a trailer. See the "Technical data"section to find out whether this applies to yourvehicle (Y page 371). In the event of increasedrear axle load, the vehicle/trailer combinationmay not exceed a maximum speed of 60 mph(100 km/h) for reasons concerning the operat-ing permit. This also applies in countries in

Towing a trailer 203

Z

which the maximum permissible speed for vehi-cle/trailer combinations is above 60 mph(100 km/h).When towing a trailer, your vehicle's handlingcharacteristics will be different in comparison towhen driving without a trailer and it will con-sume more fuel.Shift to a lower gear on long and steep downhillgradients.This also applies to:Ractivated DISTRONIC PLUSRactivated cruise controlThis will use the braking effect of the engine, sothat less braking will be required tomaintain thespeed. This relieves the load on the brake sys-tem and prevents the brakes from overheatingand wearing too quickly. If you need additionalbraking, depress the brake pedal repeatedlyrather than continuously.

Driving tipsIf the trailer swings from side to side:X Do not accelerate.X Do not counter-steer.X Brake if necessary.RMaintain a greater distance from the vehiclein front than when driving without a trailer.RAvoid braking abruptly. If possible, brake gen-tly at first to allow the trailer to run on. Then,increase the braking force rapidly.RThe values given for gradient-climbing capa-bilities from a standstill refer to sea level.When driving in mountainous areas, note thatthe power output of the engine and, conse-quently, the vehicle's gradient-climbing capa-bility, decreases with increasing altitude.

Installing the ball coupling

G WARNINGIf the ball coupling is not correctly installedand secured, it could come loose while drivingand endanger other road users. There is a riskof an accident and injury.Install and secure the ball coupling as descri-bed in the ball coupling manufacturer's instal-lation instructions. Make sure that the ball

coupling is correctly installed and securedbefore every journey.

G WARNINGIf the ball coupling is not installed and securedcorrectly the trailer may come loose. There isa risk of an accident.Install and secure the ball coupling as descri-bed in the ball coupling installation instruc-tions. Make sure that the ball coupling isinstalled and secured correctly before everyjourney.

X Pull protective cap: in the direction of thearrow, out of the ball coupling recess.

X Stow protective cap: so that it cannot bethrown around.

X Observe the manufacturer's installationinstructions.Observe the loading guidelines (Y page 278)and the safety notes regarding stowagespaces (Y page 278).

Coupling up a trailer! Do not connect the trailer's brake system (iffeatured) to the hydraulic brake system of thetowing vehicle, as the latter is equipped withan anti-lock brake system. Doing so will resultin a loss of function of the brake systems ofboth the vehicle and the trailer.

X Apply the vehicle's electric parking brakemanually.

X Start the engine.X Shift the transmission to positionj.X Vehicles with AIR BODY CONTROL: selectthe Comfort drive program.


X Switch off the engine.X Close the doors and tailgate.X Couple up the trailer.X Establish the electrical connection betweenthe vehicle and the trailer.

X Check that the trailer lighting system is work-ing.

X Push the combination switch upwards/down-wards and check whether the correspondingturn signal on the trailer flashes.

A trailer that is connected is recognized onlywhen the electrical connection is establishedcorrectly and when the lighting system is work-ing properly. The function of other systems alsodepends on this, for example:RESP®RPARKTRONICRActive Parking AssistRActive Blind Spot AssistRActive Lane Keeping AssistVehicles with AIR BODYCONTROL: if you coupleup a trailer, the vehicle always remains at high-way level. Observe the following note when cou-pling up a trailer:RUnless highway level has been set manually,the vehicle is automatically lowered to high-way level. If a speed of 5 mph (8 km/h) hasbeen reached, this may be the case.

These restrictions apply to accessories that aresupplied with power via the trailer socket in yourvehicle, e.g. a rear bicycle rack.Observe the maximum permissible trailerdimensions (width and length).Most U.S. states and all Canadian provincesrequire by law:RSafety chains between the towing vehicle andthe trailer. The chains should be cross-woundunder the trailer drawbar.

Check thespecific legal requirements applicable to yourstate.If the trailer becomes detached from the tow-ing vehicle, the safety feature applies thetrailer brakes.

Towing a trailerThere are several legal requirements for towinga trailer, e.g. the maximum permissible speed.Make sure that your car/trailer combinationcomplies with the local regulations:Rin your place of residenceRat your destinationThe police and local authorities can provide reli-able information.To accumulate driving experience and accustomyourself to the new handling characteristics,practice the following at a location where thereis no traffic:RCorneringRStoppingRBacking upCheck the following before the journey:RTrailer tow hitchRSafety switch for braked trailersRSafety chainsRElectrical connectionsRLighting systemRWheels and tiresRLoad securingAdjust the exterior mirrors so that you have aclear view of the rear section of the trailer.If the trailer is equipped with electronically con-trolled brakes, pull away carefully in the car/trailer combination. Brake manually using thebrake controller and check whether the brakesfunction correctly.Regularly check that the load is secure.When towing a trailer, your vehicle's handlingcharacteristics will be different in comparisonwith when driving without a trailer.The vehicle/trailer combination:Ris heavierRis restricted in its acceleration and gradient-climbing capabilityRhas an increased braking distanceRis affected more by strong crosswindsRdemands more sensitive steeringRhas a larger turning circleAvoid sudden steering movements.Avoid braking abruptly. If possible, brake gentlyat first to allow the trailer to run on. Then,increase the braking force rapidly.

When overtaking, pay particular attention to theextended length of your vehicle/trailer combi-nation.Due to the length of the vehicle/trailer combi-nation, you require additional road space whenovertaking before you can change back to theoriginal lane.If the automatic transmission repeatedly shiftsbetween gears on uphill or downhill gradients,shift to a lower gear.Driving in a lower gear and at a reduced speeddecreases the risk of engine damage.If the coolant temperature increases signifi-cantly when climate control is switched on,switch climate control off.Coolant heat can also be dissipated by openingthe windows and switching the ventilationblower and the interior temperature to the high-est level.

Decoupling a trailer

G WARNINGIf you uncouple a trailer with the overrunbrake engaged, you could trap your handbetween the vehicle and the trailer drawbar.There is a risk of injury.Do not uncouple a trailer if the overrun brakeis engaged.

G WARNINGVehicles with level control:The vehicle is lowered as soon as you discon-nect the trailer cable. This could result in yourlimbs or those of other people that arebetween the vehicle body and tires or under-neath the vehicle being trapped. There is arisk of injury.Make sure that nobody is in the immediatevicinity of the wheel housings or under thevehicle when you disconnect the trailer cable.

! Do not disconnect a trailer with an engagedoverrun brake. Otherwise, your vehicle couldbe damaged by the rebounding of the overrunbrake.

X Apply the vehicle's parking brake manually.X Shift the transmission to positionj.

X Close all doors and the tailgate.X Switch off the engine.X Secure the vehicle and trailer against rollingaway.

X Remove the trailer cable.X Remove the safety chains, if there are any.X Uncouple the trailer.

Removing the ball couplingX Observe the manufacturer's installationinstructions.

X Press the protective cap into the ball couplingrecess.

X Make sure that the protective cap is firmly inplace.

Observe the loading guidelines (Y page 278)and the safety notes regarding stowage spaces(Y page 278).Information on cleaning and care of the trailertow hitch (Y page 316).

Trailer power supply! Accessories with a maximum power con-sumption of 180 W can be connected to thepermanent power supply.Youmust not charge a trailer battery using thepower supply.

The trailer socket of your vehicle is equipped atthe factory with a permanent power supply.The permanent power supply is supplied viatrailer socket pin 4.The trailer's permanent power supply isswitched off in the event of low vehicle supplyvoltage and after six hours at the latest.A qualified specialist workshop can providemore information about installing the trailerelectrics.

Permissible trailer loads and trailerdrawbar noseweights

Weight specificationsThe gross trailer weight is calculated as theweight of the trailer plus the weight of the loadand the trailer's equipment.


You will find permissible trailer loads under"Technical data" (Y page 371).

Loading a trailerRWhen loading the trailer, make sure that nei-ther the permissible gross trailer weight northe permissible gross vehicle weight areexceeded. The permissible gross vehicleweight is indicated on the identification plateon the B-pillar on the driver's side of the vehi-cle.You can find themaximum permissible valueson the type plates of your vehicle and thetrailer. When calculating how much weightthe vehicle and trailer may carry, pay atten-tion to the respective lowest values.RThe trailer drawbar load on the ball couplingmust be added to the rear axle load to avoidexceeding the permissible gross axle weight.The permissible gross vehicle weight is indi-cated on the identification plate on the B-pil-lar on the driver's side of the vehicle.

Mercedes-Benz recommends a trailer loadwhere the trailer drawbar noseweight accountsfor 8% to 15% of the permissible gross trailerweight.Additional accessories, passengers and loadreduce the permissible trailer load and nose-weight that your vehicle can tow.

Checking the vehicle and trailer weightRHave the towing vehicle, including the driver,passengers and load, and completely loadedtrailer weighed on a suitable weighingmachine. This will allow you to ensure that theweights of the towing vehicle and trailer com-ply with the maximum permissible values.RCheck the gross axleweight rating of the frontand rear axles, the gross weight of the trailerand trailer drawbar load.

General notes

The multimedia system section in this Opera-tor's Manual describes the basic principles foroperation. More information can be found in theDigital Operator's Manual.



Youmust observe the legal requirements for thecountry in which you are currently driving whenoperating the multimedia system.The multimedia system calculates the route tothe destination without taking the following intoaccount, for example:Rtraffic lightsRstop and yield signsRparking or stopping restrictionsRroad narrowingRother road and traffic rules and regulationsThe multimedia system may give incorrect nav-igation recommendations if the actual street/traffic situation does not correspond with thedigital map's data.For example:Ra diverted routeRthe road layout or the direction of a one-waystreet has been changed

For this reason, you must always observe roadand traffic rules and regulations during yourjourney. Road and traffic rules and regulationsalways have priority over multimedia systemdriving recommendations.Navigation announcements are intended todirect you while driving without diverting yourattention from the road and driving.

Please always use this feature instead of con-sulting the map display for directions. Lookingat the icons ormap display can distract you fromtraffic conditions and driving, and increase therisk of an accident.This equipment complies with FCC radiationexposure limits set forth for uncontrolled equip-ment and meets the FCC radio frequency (RF)Exposure Guidelines in Supplement C to OET65.This equipment has very low levels of RF energythat is deemed to comply without maximumpermissive exposure evaluation (MPE). How-ever, it is recommended to install it at a distanceof at least 8 inches (approx. 20 cm) between theradiation source and a person's body (notincluding limbs such as hands, wrists, feet andlegs).

G WARNINGModifications to electronic components, theirsoftware as well as wiring can impair theirfunction and/or the function of other net-worked components. In particular, systemsrelevant to safety could also be affected. As aresult, these may no longer function as inten-ded and/or jeopardize the operating safety ofthe vehicle. There is an increased risk of anaccident and injury.Never tamper with the wiring as well as elec-tronic components or their software. Youshould have all work to electrical and elec-tronic equipment carried out at a qualifiedspecialist workshop.

Function restrictions

For safety reasons, some functions are restric-ted or unavailable while the vehicle is in motion.You will notice this, for example, because eitheryou will not be able to select certain menu itemsor a message will appear to this effect.

Operation

Information on drivingCheck the tire pressure when the vehicle isheavily laden and adjust prior to a trip.While driving, pay attention to vibrations, noisesand unusual handling characteristics, e.g. pull-ing to one side. This may indicate that thewheels or tires are damaged. If you suspect thata tire is defective, reduce your speed immedi-ately. Stop the vehicle as soon as possible tocheck the wheels and tires for damage. Hiddentire damage could also be causing the unusualhandling characteristics. If you find no signs ofdamage, have the tires and wheels checked at aqualified specialist workshop.When parking your vehicle, make sure that thetires do not get deformed by the curb or otherobstacles. If they cannot be avoided, drive overobstacles such as curbs slowly and at an obtuseangle. Otherwise, you may damage the wheelsor tires.

Regular checking of wheels and tires

G WARNINGDamaged tires can cause tire inflation pres-sure loss. As a result, you could lose control ofyour vehicle. There is a risk of accident.Check the tires regularly for signs of damageand replace any damaged tires immediately.

Checkwheels and tires for damage at least oncea month. Check wheels and tires after driving

off-road or on rough roads. Damaged wheelscan cause a loss of tire pressure.Pay particular attention to damage such as:Rcuts in the tiresRpunctures in the tiresRtears in the tiresRbulges on tiresRdeformation or severe corrosion on wheelsRegularly check the tire tread depth and thecondition of the tread across the whole width ofthe tire (Y page 337). If necessary, turn thefront wheels to full lock in order to inspect theinner side of the tire surface.All wheels must have a valve cap to protect thevalve against dirt and moisture. Do not mountanything onto the valve other than the standardvalve cap or other valve caps approved byMercedes-Benz for your vehicle. Do not use anyother valve caps or systems, e.g. tire pressuremonitoring systems.Regularly check the pressure of all the tires par-ticularly prior to long trips. Adjust the tire pres-sure as necessary (Y page 339).The service life of tires depends, among otherthings, on the following factors:RDriving styleRTire pressureRDistance covered

Notes on tire tread

G WARNINGInsufficient tire tread will reduce tire traction.The tire is no longer able to dissipate water.This means that on wet road surfaces, the riskof hydroplaning increases, in particular wherespeed is not adapted to suit the driving con-ditions. There is a risk of accident.If the tire pressure is too high or too low, tiresmay exhibit different levels of wear at differ-ent locations on the tire tread. Thus, youshould regularly check the tread depth andthe condition of the tread across the entirewidth of all tires.Minimum tire tread depth for:RSummer tires:â in (3 mm)RM+S tires:ã in (4 mm)

For safety reasons, replace the tires beforethe legally prescribed limit for the minimumtire tread depth is reached.

Marking: shows where the bar indicator(arrow) for tread wear is integrated into the tiretread.Treadwear indicators (TWI) are required by law.Six indicators are positioned on the tire tread.They are visible once a tread depth of approx-imatelyá in (1.6mm) has been reached. If thisis the case, the tire is so worn that it must bereplaced.

Selecting, mounting and replacingtiresROnly mount tires and wheels of the same typeand make.Exception: it is permissible to install a differ-ent type or make in the event of a flat tire.Observe the "MOExtended tires (tires withrun-flat characteristics" section (Y page 321).ROnly mount tires of the correct size onto thewheels.RBreak in new tires at moderate speeds for thefirst 60 miles (100 km). The new tires onlyreach their full performance after this dis-tance.RDo not drive with tires which have too littletread depth, as this significantly reduces thetraction on wet roads (hydroplaning).RReplace the tires after six years at the latest,regardless of wear.

Winter operation

General notesHave your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.Observe the notes in the "Changing a wheel"section (Y page 356).

Driving with summer tiresAt temperatures below 45 ‡ (+7 †), summertires lose elasticity and therefore traction andbraking power. Change the tires on your vehicleto M+S tires. Using summer tires at very coldtemperatures could cause cracks to form,thereby damaging the tires permanently.Mercedes-Benz cannot accept responsibility forthis type of damage.

G WARNINGDamaged tires can cause tire inflation pres-sure loss. As a result, you could lose control ofyour vehicle. There is a risk of accident.Check the tires regularly for signs of damageand replace any damaged tires immediately.

M+S tires

G WARNINGM+S tires with a tire tread depth of less thanã in (4 mm) are not suitable for use in winterand do not provide sufficient traction. There isa risk of an accident.M+S tires with a tread depth of less thanã in(4 mm) must be replaced immediately.

At temperatures below 45 ‡ (+7†), use wintertires or all-season tires. Both types of tire areidentified by the M+S marking.Only winter tires bearing thei snowflakesymbol in addition to the M+S marking providethe best possible grip in wintry road conditions.Only these tires will allow driving safety systemssuch as ABS and ESP® to function optimally inwinter. These tires have been developed specif-ically for driving in snow.UseM+S tires of the samemake and tread on allwheels to maintain safe handling characteris-tics.Always observe the maximum permissiblespeed specified for the M+S tires you havemounted.When you have mounted the M+S tires:X Check the tire pressures (Y page 342).X Vehicles for Canada: restart the tire pres-sure loss warning system (Y page 343).

X Restart the tire pressure monitor(Y page 345).

Snow chains

G WARNINGIf snow chains are installed to the frontwheels, they may drag against the vehiclebody or chassis components. This couldcause damage to the vehicle or the tires.There is a risk of an accident.To avoid hazardous situations:Rnever install snow chains to the frontwheelsRalways install snow chains in pairs to therear wheels.

The tire pressure table contains the recommen-ded pressures for cold tires for various operat-ing conditions, i.e. differing load and speed con-ditions.If a tire size precedes a tire pressure, the fol-lowing tire pressure information is only valid forthat tire size; see illustration (example).

The load conditions "partially laden" and "fullyladen" are defined in the table for different num-bers of occupants and amounts of luggage. Theactual number of seats may differ.

Some tire pressure tables show only the rimdiameters instead of the full tire size, e.g. R18.The rim diameter is part of the tire size and canbe found on the tire sidewall (Y page 351).If the tire pressures have been set to the lowervalues for lighter loads and/or lower roadspeeds, the pressures should be reset to thehigher values:Rif you want to drive with an increased loadand/orRif you want to drive at higher road speedsThe tire pressures for increased loads and/orhigher road speeds, shown in the tire pressuretable, may have a negative effect on drivingcomfort.If the tire pressure is not set correctly, this canlead to an excessive build up of heat and a sud-den loss of pressure.For more information, contact a qualified spe-cialist workshop.

Important notes on tire pressure

G WARNINGIf the tire pressure drops repeatedly, thewheel, valve or tire may be damaged. Tirepressure that is too low may result in a tireblow-out. There is a risk of an accident.RCheck the tire for foreign objects.RCheck whether the wheel is losing air or thevalve is leaking.

If you are unable to rectify the damage, con-tact a qualified specialist workshop.

G WARNINGIf you fit unsuitable accessories onto tirevalves, the tire valves may be overloaded andmalfunction, which can cause tire pressureloss. Due to their design, retrofitted tire pres-sure monitors keep the tire valve open. Thiscan also result in tire pressure loss. There is arisk of an accident.Only screw the standard valve cap or othervalve caps approved by Mercedes-Benz foryour vehicle onto the tire valve.

Use a suitable pressure gauge to check the tirepressure. The outer appearance of a tire doesnot permit any reliable conclusion about the tirepressure. On vehicles equipped with the elec-tronic tire pressure monitor, the tire pressurecan be checked in the on-board computer.The tire temperature and pressure increasewhen the vehicle is in motion. This is dependenton the driving speed and the load.Therefore, you should only correct tire pres-sures when the tires are cold.The tires are cold:Rif the vehicle has been parked with the tiresout of direct sunlight for at least three hoursandRif the vehicle has not been driven further than1 mile (1.6 km)

The tire temperature changes depending on theoutside temperature, the vehicle speed and thetire load. If the tire temperature changes by18 ‡ (10 †), the tire pressure changes byapproximately 10 kPa (0.1 bar/1.5 psi). Takethis into account when checking the pressure ofwarm tires. Only correct the tire pressure if it is

too low for the current operating conditions. Ifyou check the tire pressure when the tires arewarm, the resulting value will be higher than ifthe tires were cold. This is normal. Do notreduce the tire pressure to the value specifiedfor cold tires. The tire pressure would otherwisebe too low.Observe the recommended tire pressures forcold tires:Ron the Tire and Loading Information placardon the B-pillar on the driver's sideRin the tire pressure table on the fuel filler flap(Y page 149)

Underinflated or overinflated tires

Underinflated tires

G WARNINGTires with pressure that is too low can over-heat and burst as a consequence. In addition,they also suffer from excessive and/or irreg-ular wear, which can severely impair the brak-ing properties and the driving characteristics.There is a risk of an accident.Avoid tire pressures that are too low in all thetires, including the spare wheel.

Underinflated tires may:Roverheat, leading to tire defectsRadversely affect handlingRwear excessively and/or unevenlyRhave an adverse effect on fuel consumption

Overinflated tires

G WARNINGTires with excessively high pressure can burstbecause they are damaged more easily byroad debris, potholes etc. In addition, theyalso suffer from irregular wear, which canseverely impair the braking properties and thedriving characteristics. There is a risk of anaccident.Avoid tire pressures that are too high in all thetires, including the spare wheel.

Checking the tire pressures

Important safety notesObserve the notes on tire pressure(Y page 339).Information on air pressure for the tires on yourvehicle can be found:Ron the vehicle's Tire and Loading Informationplacard on the B-pillarRin the tire pressure table in the fuel filler flap(Y page 149)Rin the "Tire pressure" section

Checking tire pressures manuallyTo determine and set the correct tire pressure,proceed as follows:X Remove the valve cap of the tire that is to bechecked.

X Press the tire pressure gauge securely ontothe valve.

X Read the tire pressure and compare it to therecommended value on the Tire and LoadingInformation placard or the tire pressure table(Y page 339).

X If the tire pressure is too low, increase the tirepressure to the recommended value.

X If the tire pressure is too high, release air. Todo so, press down the metal pin in the valve,using the tip of a pen for example. Then checkthe tire pressure again using the tire pressurechecker.

X Screw the valve cap onto the valve.X Repeat these steps for the other tires.

Tire pressure loss warning system

General notesWhile the vehicle is in motion, the tire pressureloss warning system monitors the set tire pres-sure using the rotational speed of the wheels.This enables the system to detect significantpressure loss in a tire. If the speed of rotation ofa wheel changes as a result of a loss of pressure,a corresponding warningmessage will appear inthe multifunction display.You can recognize the tire pressure losswarningby the Run Flat Indicator Active Press'OK' to Restart message which appears inthe Service menu of the multifunction display.Information on the message display can befound in the "Restarting the tire pressure losswarning system" section (Y page 343).

Important safety notesThe tire pressure warning system does not warnyou of an incorrectly set tire pressure. Observethe notes on the recommended tire pressure(Y page 339).The tire pressure loss warning does not replacethe need to regularly check the tire pressure. Aneven loss of pressure on several tires at the


same time cannot be detected by the tire pres-sure loss warning system.The tire pressuremonitor is not able to warn youof a sudden loss of pressure, e.g. if the tire ispenetrated by a foreign object. In the event of asudden loss of pressure, bring the vehicle to ahalt by braking carefully. Avoid abrupt steeringmovements.The function of the tire pressure loss warningsystem is limited or delayed if:Rsnow chains are mounted on your vehicle'stires.Rroad conditions are wintry.Ryou are driving on sand or gravel.Ryou adopt a very sporty driving style (corner-ing at high speeds or driving with high rates ofacceleration).Ryou are towing a very heavy or large trailer.Ryou are driving with a heavy load (in the vehi-cle or on the roof).

Tire pressure monitor

General notesIf a tire pressure monitor is installed, the vehi-cle's wheels have sensors that monitor the tirepressures in all four tires. The tire pressuremon-itor warns you if the pressure drops in one ormore of the tires. The tire pressure monitor onlyfunctions if the corresponding sensors areinstalled in all wheels.Information on tire pressures is displayed in themultifunction display. After a few minutes ofdriving, the current tire pressure of each tire isshown in the Servicemenu of themultifunctiondisplay; see illustration (example).

Information on the message display can befound in the "Checking the tire pressure elec-tronically" section (Y page 345).


G WARNINGEach tire, including the spare (if provided),should be checked at least once every twoweeks when cold and inflated to the pressurerecommended by the vehicle manufactureron the Tire and Loading Information placardon the driver's door B-pillar or the tire pres-sure label on the inside of the fuel filler flap. Ifyour vehicle has tires of a different size thanthe size indicated on the Tire and LoadingInformation placard or, if available, the tirepressure label, you should determine theproper tire pressure for those tires.As an added safety feature, your vehicle hasbeen equippedwith a tire pressuremonitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tiresare significantly underinflated. Accordingly,when the low tire pressure telltale lights up,you should stop and check your tires as soonas possible, and inflate them to the properpressure. Driving on a significantly underin-flated tire causes the tire to overheat and canlead to tire failure.Underinflation also reduces fuel efficiencyand tire tread life, andmay affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tiremaintenance, and it is the driver's responsi-bility to maintain correct tire pressure, even ifunderinflation has not reached the level to

trigger illumination of the TPMS low tire pres-sure telltale.Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the sys-tem detects a malfunction, the warning lampwill flash for approximately a minute and thenremain continuously illuminated. Thissequencewill be repeated every time the vehi-cle is started as long as the malfunctionexists. When the malfunction indicator is illu-minated, the systemmay not be able to detector signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation of incom-patible replacement or alternate tires orwheels on the vehicle that prevent the TPMSfrom functioning properly. Always check theTPMS malfunction telltale after replacing oneor more tires or wheels on your vehicle toensure that the replacement or alternate Tiresand wheels allow the TPMS to continue tofunction properly.

It is the driver's responsibility to set the tirepressure to that recommended for cold tireswhich is suitable for the operating situation(Y page 339). Note that the correct tire pressurefor the current operating situation must first betaught-in to the tire pressure monitor. If a sub-stantial loss of pressure occurs, the warningthreshold for the warning message is aligned tothe taught-in reference values. Restart the tirepressuremonitor after adjusting the pressure ofthe cold tires (Y page 345). The current pres-sures are saved as new reference values. As aresult, a warning message will appear if the tirepressure drops significantly.The tire pressure monitor does not warn you ofan incorrectly set tire pressure. Observe thenotes on the recommended tire pressure(Y page 339).The tire pressuremonitor is not able to warn youof a sudden loss of pressure, e.g. if the tire ispenetrated by a foreign object. In the event of asudden loss of pressure, bring the vehicle to ahalt by braking carefully. Avoid abrupt steeringmovements.


The tire pressure monitor has a yellow warninglamp in the instrument cluster for indicatingpressure loss or a malfunction. Whether thewarning lamp flashes or lights up indicateswhether a tire pressure is too low or the tirepressure monitor is malfunctioning:Rif the warning lamp is lit continuously, the tirepressure on one or more tires is significantlytoo low. The tire pressure monitor is not mal-functioning.Rif the warning lamp flashes for around aminute and then remains lit constantly, thetire pressure monitor is malfunctioning.

In addition to the warning lamp, a messageappears in the multifunction display. Observethe information on display messages(Y page 250).It may take up to ten minutes for a malfunctionof the tire pressure monitor to be indicated. Amalfunction will be indicated by the tire pres-sure warning lamp flashing for approximatelyone minute and then remaining lit. When themalfunction has been rectified, the tire pressurewarning lamp goes out after a few minutes ofdriving.The tire pressure values indicated by the on-board computer may differ from those meas-ured at a gas station with a pressure gauge. Thetire pressures shown by the on-board computerrefer to those measured at sea level. At highaltitudes, the tire pressure values indicated by apressure gauge are higher than those shown bythe on-board computer. In this case, do notreduce the tire pressures.The operation of the tire pressure monitor canbe affected by interference from radio transmit-ting equipment (e.g. radio headphones, two-wayradios) thatmay be being operated in or near thevehicle.

G WARNINGOverloaded tires can overheat, causing ablowout. Overloaded tires can also impair thesteering and driving characteristics and leadto brake failure. There is a risk of accident.Observe the load rating of the tires. The loadrating must be at least half of the GAWR ofyour vehicle. Never overload the tires byexceeding the maximum load.

Two instruction labels on your vehicle show themaximum possible load.(1) The Tire and Loading Information placard is

on the B-pillar on the driver's side. The Tireand Loading Information placard shows themaximum permissible number of occu-pants and themaximumpermissible vehicleload. It also contains details of the tire sizesand corresponding pressures for tiresmounted at the factory.

(2) The vehicle identification plate is on the B-pillar on the driver's side. The vehicle iden-tification plate informs you of the grossvehicle weight rating. It is made up of thevehicle weight, all vehicle occupants, thefuel and the cargo. You can also find infor-mation about the maximum gross axleweight rating on the front and rear axle.The maximum gross axle weight rating isthe maximum weight that can be carried byone axle (front or rear axle). Never exceedthe maximum load or the maximum grossaxle weight rating for the front or rear axle.

Determining the correct load limit

Step-by-step instructionsThe following steps have been developed asrequired of all manufacturers under Title 49,Code of U.S. Federal Regulations, Part 575 pur-suant to the "National Traffic and Motor VehicleSafety Act of 1966".X Step 1: Locate the statement "The combinedweight of occupants and cargo should neverexceed XXX kg or XXX lbs." on your vehicle'sTire and Loading Information placard.

X Step 2: Determine the combined weight ofthe driver and passengers that will be riding inyour vehicle.

X Step 3: Subtract the combined weight of thedriver and passengers from XXX kilograms orXXX lbs.

X Step 4: The resulting figure equals the avail-able amount of cargo and luggage load capa-city. For example, if the "XXX" amount equals1400 lbs and there will be five 150-lb pas-sengers in your vehicle, the amount of avail-

able cargo and luggage load capacity is650 lbs (1400 - 750 (5 x 150) = 650 lbs).

X Step 5: Determine the combined weight ofluggage and cargo being loaded on the vehi-

cle. That weight may not safely exceed theavailable cargo and luggage load capacity cal-culated in step 4.

Example: steps 1 to 3The following table shows examples on how to calculate total and cargo load capacities with varyingseating configurations and number and size of occupants. The following examples use a load limit of1500 lbs (680 kg). This is for illustration purposes only.Make sure you are using the actual loadlimit for your vehicle stated on your vehicle's Tire and Loading Information placard (Y page 346).The greater the combined weight of the occupants, the lower the maximum luggage load.Step 1

Uniform Tire Quality Grading Stand-ards

Overview of Tire Quality Grading Stand-ards

Uniform Tire Quality Grading Standards are U.S.government specifications. Their purpose is toprovide drivers with uniform reliable informationon tire performance data. Tire manufacturershave to grade tires using three performance fac-tors:: tread wear grade,; traction grade and= temperature grade. These regulations do notapply to Canada. Nevertheless, all tires sold inNorth America are provided with the corre-sponding quality grading markings on the side-wall of the tire.Quality grades can be found, where applicable,on the tire sidewall between tread shoulder andmaximum section width.Example:RTreadwear grade: 200RTraction grade: AARTemperature grade: AAll passenger car tiresmust conform to the stat-utory safety requirements in addition to thesegrades.

TreadwearThe treadwear grade is a comparative ratingbased on the wear rate of the tire when testedunder controlled conditions on a specified U.S.government course. For example, a tire graded150 would wear one and one-half times as wellon the government course as a tire graded 100.The relative performance of tires depends uponthe actual conditions of their use, however, andmay depart significantly from the norm due tovariations in driving habits, service practicesand differences in road characteristics and cli-mate.

Traction

G WARNINGThe traction grade assigned to this tire isbased on straight-ahead braking tractiontests, and does not include acceleration, cor-nering, hydroplaning, or peak traction char-acteristics.

! Avoid wheelspin. This can lead to damage tothe drive train.

The traction grades – from highest to lowest –are AA, A, B and C. Those grades represent thetire's ability to stop on wet pavement as meas-ured under controlled conditions on specifiedgovernment test surfaces of asphalt and con-crete. A tire marked C may have poor tractionperformance.The safe speed on a wet, snow covered or icyroad is always lower than on dry road surfaces.You should pay special attention to road condi-tions when temperatures are around freezingpoint.Mercedes-Benz recommends a minimum treaddepth ofã in (4 mm) on all four winter tires.Observe the legally required minimum tire treaddepth (Y page 337). Winter tires can reduce thebraking distance on snow-covered surfaces incomparison with summer tires. The braking dis-tance is still much further than on surfaces thatare not icy or covered with snow. Take appro-priate care when driving.

Further information on winter tires (M+S tires)(Y page 338).

Temperature

G WARNINGThe temperature grade for this tire is estab-lished for a tire that is properly inflated andnot overloaded. Excessive speed, underinfla-tion, or excessive loading, either separately orin combination, can cause excessive heatbuild-up and possible tire failure.

The temperature grades are A (the highest), B,and C, representing the tire's resistance to thegeneration of heat and its ability to dissipateheat when tested under controlled conditionson a specified indoor laboratory test wheel. Sus-tained high temperature can cause the materialof the tire to degenerate and reduce tire life, andexcessive temperature can lead to sudden tirefailure. The grade C corresponds to a level ofperformance which all passenger car tires mustmeet under the Federal Motor Vehicle SafetyStandard No. 109. Grades B and A representhigher levels of performance on the laboratorytest wheel than the minimum required by law.

The speed rating of tires mounted at the factorymay be higher than themaximum speed that theelectronic speed limiter permits.Make sure that your tires have the requiredspeed rating, e.g. when buying new tires. Youcan find information on this under "Tires"(Y page 360).Further information about reading tire data canbe obtained from any qualified specialist work-shop.

Load index

In addition to the load-bearing index, loadindex: may also be imprinted on the sidewallof the tire. You will find this after the letter thatidentifies the speed rating (Y page 351).RIf no specification is given: no text (as in theexample above), represents a standard load(SL) tireRXL or Extra Load: represents a reinforced tireRLight Load: represents a light load tireRC, D, E: represents a load range that dependson themaximum load that the tire can carry ata certain pressure


Maximum load rating

Maximum tire load: is the maximum permis-sible weight for which the tire is approved.Do not overload the tires by exceeding thespecified load limit. The maximum permissibleload can be found on the vehicle's Tire andLoading Information placard on the B-pillar onthe driver's side (Y page 346).


DOT, Tire Identification Number (TIN)US tire regulations stipulate that every tire man-ufacturer or retreadermust imprint a TIN in or onthe sidewall of each tire produced.

The TIN is a unique identification number. TheTIN enables the tiremanufacturers or retreadersto inform purchasers of recalls and other safety-relevant matters. It makes it possible for thepurchaser to easily identify the affected tires.The TIN is made up of manufacturer identifica-tion code;, tire size=, tire type code? andmanufacturing dateA.DOT (Department of Transportation): tiresymbol:marks that the tire complies with the

Changing a wheel

Flat tireThe "Breakdown assistance" section(Y page 321) contains information and notes onhow to deal with a flat tire. Information on driv-ing with MOExtended tires in the event of a flattire can be found under "MOExtended tires (tireswith run-flat characteristics" (Y page 321).

Rotating the wheels

G WARNINGInterchanging the front and rear wheels mayseverely impair the driving characteristics ifthe wheels or tires have different dimensions.The wheel brakes or suspension componentsmay also be damaged. There is a risk of acci-dent.Rotate front and rear wheels only if thewheelsand tires are of the same dimensions.

! On vehicles equipped with a tire pressuremonitor, electronic components are locatedin the wheel.Tire-mounting tools should not be used nearthe valve. This could damage the electroniccomponents.Only have tires changed at a qualified spe-cialist workshop.

Always observe the instructions and safetynotes in the "Mounting a wheel" section(Y page 357).The wear patterns on the front and rear tiresdiffer, depending on the operating conditions.Rotate the wheels before a clear wear patternhas formed on the tires. Front tires typicallywear more on the shoulders and the rear tires inthe center.On vehicles that have the same size front andrear wheels, you can rotate the tires accordingto the intervals in the tire manufacturer's war-ranty book in your vehicle documents. If no war-ranty book is available, the tires should be rota-ted every 3,000 to 6,000 miles (5,000 to10,000 km). Depending on tire wear, this maybe required earlier. Do not change the directionof wheel rotation.Clean the contact surfaces of the wheel and thebrake disc thoroughly every time awheel is rota-ted. Check the tire pressure and, if necessary,restart the tire pressure loss warning system(Y page 343) or the tire pressure monitor(Y page 345).

Direction of rotationTires with a specified direction of rotation haveadditional benefits, e.g. if there is a risk of hydro-planing. These advantages can only be gained if

356 Changing a wheelWheelsandtires

the tires are installed corresponding to thedirection of rotation.An arrow on the sidewall of the tire indicates itscorrect direction of rotation.

Storing wheelsStore wheels that are not being used in a cool,dry and preferably dark place. Protect the tiresfrom oil, grease, gasoline and diesel.

Wheel/tire combination

You can ask for information regarding permittedwheel/tire combinations at an authorizedMercedes-Benz Center.

! For safety reasons, Mercedes-Benz recom-mends that you only use tires and wheelswhich have been approved byMercedes-Benzspecifically for your vehicle.These tires have been specially adapted foruse with the control systems, such as ABS orESP®, and are marked as follows:RMO = Mercedes-Benz OriginalRMOE = Mercedes-Benz Original Extended(tires featuring run-flat characteristics)RMO1 = Mercedes-Benz Original (only cer-tain AMG tires)

Mercedes-Benz Original Extended tires mayonly be used on wheels that have been spe-cifically approved by Mercedes-Benz.Only use tires, wheels or accessories testedand approved by Mercedes-Benz. Certaincharacteristics, e.g. handling, vehicle noiseemissions or fuel consumption, may other-wise be adversely affected. In addition, whendriving with a load, tire dimension variationscould cause the tires to come into contactwith the bodywork and axle components. Thiscould result in damage to the tires or the vehi-cle.Mercedes-Benz accepts no liability for dam-age resulting from the use of tires, wheels oraccessories other than those tested andapproved.Information on tires, wheels and approvedcombinations can be obtained from any quali-fied specialist workshop.

! Retreaded tires are neither tested nor rec-ommended by Mercedes-Benz, since previ-ous damage cannot always be detected onretreaded tires. As a result, Mercedes-Benzcannot guarantee vehicle safety if retreadedtires are mounted. Do not mount used tires ifyou have no information about their previoususage.

Low outside temperaturesDEF freezes at a temperature of approximately-11 †. The vehicle is delivered from the factoryequipped with a DEF preheating system. Winteroperation can thus be guaranteed even at tem-peratures below -11 †.

Additives! Only use DEF in accordance with ISO22241. Do not use additives with DEF and donot dilute DEF with water. This may destroythe BlueTEC exhaust gas aftertreatment sys-tem.

Purity! Impurities in DEF (e.g. due to other serviceproducts, cleaning agents or dust) lead to:Rincreased emission valuesRdamage to the catalytic converterRengine damageRmalfunctions in the BlueTEC exhaust gasaftertreatment system

Assuring the purity of DEF is particularly impor-tant with respect to avoidingmalfunctions in theBlueTEC exhaust gas aftertreatment system.If DEF is pumped out of the DEF tank, e.g. duringrepair work, it must not be returned to the tank.The purity of the fluid can no longer be guaran-teed.

Additives! Do not use any additives in the engine oil.This could damage the engine.

Brake fluid

G WARNINGThe brake fluid constantly absorbs moisturefrom the air. This lowers the boiling point ofthe brake fluid. If the boiling point of the brake

fluid is too low, vapor pockets may form in thebrake system when the brakes are appliedhard. This would impair braking efficiency.There is a risk of an accident.You should have the brake fluid renewed atthe specified intervals.

When handling brake fluid, observe the impor-tant safety notes on service products(Y page 364).The brake fluid change intervals can be found inthe Maintenance Booklet.Only use brake fluid approved by Mercedes-Benz in accordance with MB-Freigabe or MB-Approval 331.0.Information about approved brake fluid can beobtained at any qualified specialist workshop oron the Internet athttp://bevo.mercedes-benz.com.

i Have the brake fluid regularly replaced at aqualified specialist workshop in accordancewith the replacement intervals and thereplacement confirmed in the MaintenanceBooklet.

Coolant


G WARNINGIf antifreeze comes into contact with hot com-ponents in the engine compartment, it mayignite. There is a risk of fire and injury.Let the engine cool down before you add anti-freeze.Make sure that antifreeze is not spillednext to the filler neck. Thoroughly clean theantifreeze from components before startingthe engine.

! Only add coolant that has been premixedwith the desired antifreeze protection. Youcould otherwise damage the engine.Further information on coolants can be foundin the Mercedes-Benz Specifications for Ser-vice Products, MB BeVo 310.1, e.g. on theInternet at http://bevo.mercedes-benz.com.Or contact a qualified specialist workshop.

! Always use a suitable coolant mixture, evenin countries where high temperatures prevail.


Otherwise, the engine cooling system is notsufficiently protected from corrosion andoverheating.

i Have the coolant regularly replaced at aqualified specialist workshop and the replace-ment confirmed in the Maintenance Booklet.

Comply with the important safety notes for ser-vice products when handling coolant(Y page 364).The coolant is a mixture of water and anti-freeze/corrosion inhibitor. It performs the fol-lowing tasks:RAnti-corrosion protectionRAntifreeze protectionRRaising the boiling pointIf the coolant has antifreeze protection down to-35 ‡ (-37 †), the boiling point of the coolantduring operation is approximately 266 ‡(130 †).The antifreeze concentrate/corrosion inhibitorconcentration in the engine cooling systemshould:Rbe at least 50%. This will protect the enginecooling system against freezing down toapproximately -35 ‡ (-37 †).Rnot exceed 55% (antifreeze protection downto -49 ‡ [-45 †]). Otherwise, heat will not bedissipated as effectively.

Mercedes-Benz recommends an antifreeze/corrosion inhibitor concentrate in accordancewith MB Specifications for Service Products310.1.

i When the vehicle is first delivered, it is filledwith a coolant mixture that ensures adequateantifreeze and anti-corrosion protection.

i The coolant is checked with every mainte-nance interval at a qualified specialist work-shop.
