is to record data that will assist in under-standing how a vehicle’s systems performedin certain crash or near crash-like situations,such as during air bag deployment or whenhitting a road obstacle. The EDR is designedto record data related to vehicle dynamicsand safety systems for a short period of time,typically 30 seconds or less.The EDR in this vehicle is designed to recordsuch data as:Rhow various systems in your vehicle areoperatingRwhether or not the driver and passengerseat belts are fastenedRhow far (if at all) the driver is depressing theaccelerator and/or brake pedal andRhow fast the vehicle is travelingThis data can help provide a better under-standing of the circumstances in whichcrashes and injuries occur. NOTE: EDR data isrecorded by your vehicle only if a non-trivialcrash situation occurs; no data is recorded bythe EDR under normal driving conditions andno personal data (e.g., name, gender, age,and crash location) are recorded. However,other parties, such as law enforcement, cancombine the EDR data with the type of per-sonal identification data routinely acquiredduring a crash investigation.To read data recorded by an EDR, specialequipment is required, and access to the vehi-cle or the EDR is needed. In addition to thevehicle manufacturer, other parties that havethe special equipment, such as law enforce-ment, can read the information by accessingthe vehicle or the EDR.EDR data may be used in civil and criminalmatters as a tool in accident reconstruction,accident claims, and vehicle safety. Since theCrash Data Retrieval CDR tool that is used toextract data from the EDR is commerciallyavailable, Mercedes-Benz USA, LLC("MBUSA") expressly disclaims any and all lia-bility arising from the extraction of this infor-mation by unauthorized Mercedes-Benz per-sonnel.

MBUSA will not share EDR data with otherswithout the consent of the vehicle owners or,if the vehicle is leased, without the consent ofthe lessee. Exceptions to this representationinclude responses to subpoenas by lawenforcement; by federal, state or local gov-ernment; in connection with or arising out oflitigation involving MBUSA or its subsidiariesand affiliates; or, as required by law.Warning: The EDR is a component of theRestraint System Module. Tampering with,altering, modifying or removing the EDR com-ponent may result in a malfunction of theRestraint System Module and other systems.State laws or regulations regarding EDRs thatconflict with federal regulation are pre-emp-ted. This means that in the event of such con-flict, the federal regulation governs. As ofFebruary 2013, 13 states have enacted lawsrelating to EDRs.

Important safety notes

Danger of electric shock

G DANGERThe vehicle's high voltage electrical system isunder high voltage. If you modify componentsin the vehicle's high-voltage electrical systemor touch damaged components, you may beelectrocuted. The components in the vehi-cle's high-voltage electrical system may bedamaged in an accident, although the damageis not visible. There is a risk of fatal injury.Following an accident, do not touch any high-voltage components and never modify thevehicle's high-voltage electrical system. Havethe vehicle towed away after an accident andthe vehicle's high-voltage electrical systemchecked by a qualified specialist workshop.

When towing a vehicle after an accident, besure to observe the following sections:RTransporting the vehicle (Y page 437)RTowing the vehicle with the rear axle raised(Y page 437)RTowing a vehicle with both axles on theground (Y page 436)

Read the safety instructions on towing andtow-starting (Y page 435).

All components of the hybrid system aremarked with yellow warning stickers thatwarn you of the danger of high voltage. Thecables of the vehicle's high-voltage electricalsystem are orange in color.The ignition must be switched off when car-rying out general tasks, such as addingwasher fluid to the windshield washer systemor checking the coolant level.

Automatic deactivation of the hybridsystem

G DANGERIf the restraint system is malfunctioning, indi-vidual restraint system components may betriggered unintentionally or might not be trig-gered at all in the event of an accident with ahigh rate of vehicle deceleration. This couldaffect Emergency Tensioning Devices or airbags, for example. The vehicle's high-voltageelectrical systemmay also not be deactivatedas intended in the event of an accident. Youcould suffer an electric shock if you touch thedamaged components of the vehicle's high-

Occupant safety

Restraint system: introductionThe restraint system reduces the risk of vehi-cle occupants coming into contact with partsof the vehicle's interior in the event of anaccident. The restraint system can alsoreduce the forces to which vehicle occupantsare subjected during an accident.The restraint system comprises:RSeat belt systemRAir bagsRChild restraint systemRChild seat securing systems

The components of the restraint systemworkin conjunction with each other. They can onlydeploy their protective function if, at all times,all vehicle occupants:Rhave fastened their seat belts correctly(Y page 53)Rhave adjusted their seat and head restraintproperly (Y page 121).

As the driver, you also have to make sure thatthe steering wheel is adjusted correctly.Observe the information relating to the cor-rect driver's seat position (Y page 120).You also have tomake sure that an air bag caninflate properly if deployed (Y page 56).An air bag supplements a correctly worn seatbelt. As an additional safety device, the airbag increases the level of protection for vehi-cle occupants in the event of an accident. Forexample, if, in the event of an accident, theprotection offered by the seat belt is suffi-cient, the air bags are not deployed. When anaccident occurs, only the air bags thatincrease protection in that particular accidentsituation are deployed. However, seat beltsand air bags generally do not protect againstobjects penetrating the vehicle from the out-side.Information on restraint system operationcan be found under "Deployment of Emer-gency Tensioning Devices and air bags"(Y page 65).For more information about children travelingwith you in the vehicle and on child restraintsystems, see "Children in the vehicle"(Y page 69).

Important safety notes

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.

Depending on the person in the front-passenger seat, the front-passenger front airbag must either be deactivated or enabled;see the following points. You must make sureof this both before and during a journey.RChildren in a child restraint system:whether the front-passenger front air bag isenabled or deactivated depends on theinstalled child restraint system, and the ageand size of the child. Therefore, be sure toobserve the notes on the "Occupant Clas-sification System (OCS)" (Y page 59) andon "Children in the vehicle" (Y page 69).There youwill also find instructions on rear-ward and forward-facing child restraint sys-tems on the front-passenger seat.RAll other persons: depending on the clas-sification of the person in the front-passenger seat, the front-passenger frontair bag is enabled or deactivated(Y page 59). Be sure to observe the noteson "Seat belts“ (Y page 51) and "Air bags"(Y page 56). 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 occu-pants in the event of an accident or the vehi-cle rolling over. This reduces the risk of vehi-cle occupants coming into contact with partsof the vehicle interior or being ejected fromthe vehicle. Furthermore, the seat belt helpsto keep the vehicle occupant in the best posi-tion in relation to the air bag.

The seat belt system comprises:RSeat beltsREmergency Tensioning Devices for thefront seat belts and the outer seat belts inthe rearRSeat belt force limiters for the front seatbelts and the outer seat belts in the rearRBelt bags for the outer seat belts in the rear,depending on the vehicle's equipment

If the seat belt is pulled out of the belt outletquickly or with a jerky movement, the beltretractor locks. The belt strap cannot beextracted any further.The Emergency Tensioning Device tightensthe seat belt in an accident, pulling the beltclose against the body. However it does notpull the vehicle occupant back in the directionof the backrest.The Emergency Tensioning Device does notcorrect an incorrect seat position or the rout-ing of an incorrectly fastened seat belt.When triggered, seat belt force limiters helpto reduce the force exerted by the seat belt onthe vehicle occupant.The seat belt force limiters for the front seatsare synchronized with the front air bags,which absorb part of the deceleration force.This can reduce the force exerted on the vehi-cle occupants during an accident.

! If the front-passenger seat is unoccupied,do not insert the belt tongue into the buckleof the front-passenger seat. This may oth-erwise lead to the triggering of the Emer-gency Tensioning Device in the event of anaccident, which will then need to bereplaced.

Important safety notesThe use of seat belts and child restraint sys-tems is required by law in:Rall 50 statesRthe U.S. territoriesRthe District of ColumbiaRall Canadian provinces

Even where this is not required by law, allvehicle occupants should correctly fastentheir seat belts before starting the journey.

G WARNINGIf the seat belt is incorrectly fastened, it can-not protect as intended. Furthermore, anincorrectly fastened seat belt can cause addi-tional injury, for example, in an accident, dur-ing braking or when abruptly changing direc-tion. This poses an increased risk of injury oreven fatal injury.Make sure that all vehicle occupants areseated properly with a correctly fastened seatbelt.

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 WARNINGObjects next to the front seat that block thebelt buckle or the moving belt anchorage onthe front seat impair the function of the Emer-gency Tensioning Devices. The EmergencyTensioning Devicesmay not function as inten-ded and the seat belt may no longer providethe intended protection. This poses anincreased risk of injury or even fatal injury.Before starting the journey, make sure thatthere are no objects around the belt buckle orbetween the front seat and door.

G WARNINGPersons under 5 ft (1.50 m) in height cannotfasten the seat belt correctly without an addi-

tional suitable restraint system. If the seatbelt is incorrectly fastened, it cannot protectas intended. Furthermore, an incorrectly fas-tened seat belt can cause additional injury, forexample, in an accident, during braking or anabrupt change of direction. This poses anincreased risk of injury or even fatal injury.For this reason, always secure persons under5 ft (1.50 m) in height in suitable restraintsystems.

If a child younger than 12 years and under 5 ft(1.50 m) in height is traveling in the vehicle:Ralways secure the child in a child restraintsystem suitable for this Mercedes-Benzvehicle. The child restraint system must beappropriate to the age, weight and size ofthe childRalways observe the instructions and safetynotes on the belt bags for the outer seatbelts in the rear (Y page 53)Ralways observe the instructions and safetynotes in the "Children in the vehicle" sec-tion of this Operator's Manual(Y page 69) in addition to the childrestraint system manufacturer's installa-tion instructionsRbe sure to observe the instructions andsafety notes on the "Occupant classifica-tion system (OCS)" (Y page 59)

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

Seat belts may sustain non-visible damage inan accident, e.g. due to glass splinters. Modi-fied or damaged seat belts may tear or fail,e.g. in an accident. Modified Emergency Ten-sioning Devices could accidentally trigger or

Air bags

IntroductionThe installation point of an air bag can be rec-ognized by the AIR BAG symbol.An air bag complements the correctly fas-tened seat belt. It is no substitute for the seat

belt. The air bag provides additional protec-tion in applicable accident situations.Not all air bags are deployed in an accident.The different air bag systems function inde-pendently from one another (Y page 65).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.

Important safety notes

G WARNINGIf you do not sit in the correct seat position,the air bag cannot protect as intended andcould even cause additional injury whendeployed. 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 theseat is in an almost upright position. Thecenter of the head restraint must supportthe head at about eye level.RMove the driver's and front-passengerseats as far back as possible. The driver'sseat position must allow the vehicle to bedriven safely.ROnly hold the steering wheel on the out-side. This allows the air bag to be fullydeployed.RAlways lean against the backrest while driv-ing. Do not lean forwards or lean againstthe door or side window. You may other-

wise be in the deployment area of the airbags.RAlways keep your feet in the footwell infront of the seat. Do not put your feet on thedashboard, for example. Your feet may oth-erwise be in the deployment area of the airbag.RFor this reason, always secure persons lessthan 5 ft (1.50 m) tall in suitable restraintsystems. Up to this height, the seat beltcannot be worn correctly.

If a child is traveling in your vehicle, alsoobserve the following notes:RAlways secure children under 12 years ofage and less than 5 ft (1.50 m) in height insuitable child restraint systems.RChild restraint systems should be installedon the rear seats.ROnly secure a child in a rearward-facingchild restraint system on the front-passenger seat when the front-passengerfront air bag is deactivated. If thePASSENGER AIR BAGOFF indicator lamp ispermanently lit, the front-passenger frontair bag is deactivated (Y page 50).RAlways observe the instructions and safetynotes on the "Occupant Classification Sys-tem (OCS)" (Y page 59) and on "Childrenin the vehicle" (Y page 69) in addition tothe child restraint system manufacturer'sinstallation instructions.

Objects in the vehicle interior may pre-vent an air bag from functioning correctly.Before starting your journey and to avoid risksresulting from the speed of the air bag as itdeploys, make sure 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 deploy-

ment area of an air bag, e.g. to doors, sidewindows, rear side trim or side walls.Rno heavy, sharp-edged or fragile objectsare in the pockets of your clothing. Storesuch objects 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 properlyany more. 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.

Driver's knee bag: deploys under the steer-ing column. The driver's knee bag is alwaysdeployed along with the driver's front air bag.The driver's knee bag offers additional thigh,knee and lower leg protection for the occu-pant in the driver's seat.

Side impact air bags

G WARNINGUnsuitable seat covers could restrict or evenprevent the deployment of the air bags inte-grated into the seats. Consequently, the airbags cannot protect vehicle occupants asthey are designed to do. In addition, the func-tion of the Occupant Classification System

(OCS) could be restricted. 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 outerbolster of the seat backrest.When deployed, the side impact air bag offersadditional thorax protection. It also offersadditional pelvis protection for occupants inthe front seats. However, it does not protectthe:RheadRneckRarmsIn the event of a side impact, the side impactair bag is deployed on the side on which theimpact occurs.The side impact air bag on the front-passenger side (front) deploys in the follow-ing situations:Rthe OCS system detects that the front-passenger seat is occupied orRthe belt tongue is engaged in the beltbuckle of the front-passenger seat

If the belt tongue is engaged in the beltbuckle, the side impact air bag on the front-passenger side deploys if an appropriate acci-dent situation occurs. In this case, deploy-ment is independent of whether the front-passenger seat is occupied or not.

Window curtain air bags

Window curtain air bags: are integratedinto the side of the roof frame and deployed inthe area 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 orarms.In the event of a side impact, the window cur-tain air bag is deployed on the side on whichthe impact 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 65).

Cushion air bags

i Observe the "Important safety notes" sec-tion (Y page 56).

The rear reclining seat is equipped with acushion air bag. If the seat backrest isreclined, the cushion air bag can provide addi-tional occupant protection in the event offrontal collision situations. When triggered,the cushion air bag deploys under the seatcushion. This helps prevent the occupantfrom slipping off the seat cushion.

G WARNINGIf a child restraint system is installed and theseat backrest is reclined too far backwards,the cushion air bag may deploy by mistake inthe event of an accident. There is an increasedrisk of injury.

When using a child restraint system, alwaysensure that the seat is correctly adjusted andthat the backrest is almost vertical.

If you install a child restraint system on therear reclining seat, always observe:Rthe instructions and safety notes in "Chil-dren in the vehicle" (Y page 69)Rthe child restraint system manufacturer'sinstallation instructions.

Occupant Classification System(OCS)

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

PrerequisitesTo be classified correctly, the front passengermust sit:Rwith the seat belt fastened correctlyRin an almost upright position with theirback against the seat backrestRwith their feet resting on the floor, if possi-ble

If the front passenger does not observe theseconditions, OCS may produce a false classi-fication, 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,be sure to observe the correct positioning of

Deployment of Emergency TensioningDevices and air bags

Important safety notes

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 replacedand to have any malfunctioning air bagsrepaired. This will help to make sure the airbags continue to perform their protectivefunction for the vehicle occupants in theevent of a crash.

G WARNINGPyrotechnic Emergency Tensioning Devicesthat have been deployed 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.Therefore, have pyrotechnic Emergency Ten-sioning Devices which have been triggeredimmediately replaced at a qualified specialistworkshop.

An electric motor is used by PRE-SAFE® totrigger the tightening of the seat belt in haz-ardous situations. This procedure is reversi-ble.If Emergency Tensioning Devices are trig-gered or air bags are deployed, you will hear abang, and a small amount of powder may also

be released. The 6 restraint system warn-ing lamp lights up.Only in rare cases will the bang affect yourhearing. The powder that is released gener-ally does not constitute a health hazard, but itmay cause short-term breathing difficulties inpeople with asthma or other respiratory prob-lems. To avoid this, youmay wish to get out ofthe vehicle or open the windows as soon as itis safe to do so.Air bags and pyrotechnic Emergency Tension-ing Devices (ETDs) contain perchlorate mate-rial, which may require special handling andregard for the environment. National guide-lines must be observed during disposal. InCalifornia, see www.dtsc.ca.gov/HazardousWaste/Perchlorate/index.cfm.

Method of operationDuring the first stage of a collision, therestraint system control unit evaluates impor-tant physical data relating to vehicle deceler-ation or acceleration, such as:RdurationRdirectionRintensityBased on the evaluation of this data, therestraint system control unit triggers theEmergency Tensioning Devices during a fron-tal or rear collision.An Emergency Tensioning Device can only betriggered, if:Rthe ignition is switched onRthe components of the restraint system areoperational; see "Restraint system warninglamp" (Y page 50)Rthe belt tongue is engaged in the buckle onthe respective front-passenger seat

The Emergency Tensioning Devices in therear compartment are triggered independ-ently of the lock status of the seat belts.

Vehicles with belt bags: the belt bags arealso deployed depending on the type andseverity of the accident.Vehicles with a rear reclining seat: theEmergency Tensioning Device is only trig-gered if the belt buckle tongue is engaged inthe belt buckle.If the seat backrest is reclined, the cushion airbag will also be deployed depending on thetype and severity of the accident.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 activatedor deactivated depending on the person onthe front-passenger seat. The front-passenger front air bag can only deploy in anaccident if the PASSENGER AIR BAG ON indi-cator lamp is lit. Observe the information onthe PASSENGER AIR BAG indicator lamps(Y page 50).Your vehicle has two-stage front air bags.During the first deployment stage, the frontair bag is filled with propellant gas to reducethe risk of injuries. The front air bag is fullydeployed with the maximum amount of pro-pellant gas if a second deployment thresholdis reached within a few milliseconds.The activation threshold of the EmergencyTensioning Devices and the air bag are deter-mined by evaluating the rate of vehicle decel-eration or acceleration which occurs at vari-ous points in the vehicle. This process is pre-emptive in nature. Deployment should takeplace in good time at the start of the collision.

The rate of vehicle deceleration or accelera-tion and the direction of the force are essen-tially determined by:Rthe distribution of forces during the colli-sionRthe collision angleRthe deformation characteristics of the vehi-cleRthe characteristics of the object with whichthe vehicle has collided

Factorswhich can only be seen andmeasuredafter a collision has occurred do not play adecisive role in the deployment of an air bag.Nor do they provide an indication of air bagdeployment.The vehicle can be deformed considerably,without an air bag being deployed. This is thecase if only parts which are relatively easilydeformed are affected and the rate of decel-eration is not high. Conversely, air bags maybe deployed even though the vehicle suffersonly minor deformation. This is the case if, forexample, very rigid vehicle parts such as lon-gitudinal bodymembers are hit, and sufficientdeceleration occurs as a result.If the restraint system control unit detects aside impact or that the vehicle is rolling over,the relevant restraint system components areactivated independently of one anotherdepending on the apparent type of accident.If the systemdetermines a need for additionalprotection for the vehicle occupants, theEmergency Tensioning Devices are triggered.RSide impact air bags on the side of impact,independently of the Emergency Tension-ing Device and the use of the seat belt onthe driver's seat and outer seats in the sec-ond row

PRE-SAFE® (anticipatory occupantprotection system)

Introduction

In certain hazardous situations, PRE-SAFE®takes pre-emptive measures to protect thevehicle occupants.

Important safety notes

! Make sure that there are no objects in thefootwell under or behind the seats whenmoving the seats back. There is a risk thatthe seats and/or the objects could be dam-aged.

Despite your vehicle being equipped with thePRE-SAFE® system, the possibility of per-sonal injuries occurring as a result of an acci-dent cannot be eliminated. Always adapt yourdriving style to suit the prevailing road andweather conditions and maintain a safe dis-tance from the vehicle in front. Drive care-fully.

Function

PRE-SAFE® intervenes:Rin emergency braking situations, e.g. whenBAS is activatedRin critical driving situations, e.g. when phys-ical limits are exceeded and the vehicleundersteers or oversteers severelyRvehicles with the Driving Assistance pack-age: when a driver assistance system inter-venes powerfully or the radar sensor sys-tem detects an imminent danger of colli-sion in certain situations

PRE-SAFE® takes the following measuresdepending on the hazardous situation detec-ted:Rthe front seat belts are pre-tensioned.Rif the vehicle skids, the panorama roof withpower tilt/sliding panel and the side win-dows are closed so that only a small gapremains.Rthe front-passenger seat is adjusted if it isin an unfavorable position.Rfor vehicles with electrically adjustable rearseats: the outer rear seats are adjusted ifthey are in an unfavorable position.Rvehicles with a multicontour seat: the airpressure in the side bolsters of the seatbackrest is increased.Rvehicles with seat belt extenders: the seatbelts of the outer rear seats are pre-ten-sioned.

PRE-SAFE® PLUS (anticipatory occu-pant protection system PLUS)

Introduction

PRE-SAFE® PLUS is only available in vehicleswith the Driving Assistance package.Using the radar sensor system, PRE-SAFE®PLUS is able to detect that a head-on or rear-end collision is imminent. In certain hazard-ous situations, PRE-SAFE® PLUS takes pre-emptive measures to protect the vehicleoccupants.

Important safety notes

The intervention of PRE-SAFE® PLUS cannotprevent an imminent collision.The driver is not warned when PRE-SAFE®PLUS intervenes.PRE-SAFE® PLUS does not intervene if thevehicle is backing up.PRE-SAFE® PLUS does not perform brakingactions while the vehicle is in motion or whenParking Guidance is active.

Function

PRE-SAFE® PLUS intervenes in certain situa-tions if the radar sensor system detects animminent head-on or rear-end collision.

PRE-SAFE® PLUS takes the following meas-ures depending on the hazardous situationdetected:Rif the radar sensor system detects that ahead-on collision is imminent, the seatbelts are pre-tensioned.Rif the radar sensor system detects that arear-end collision is imminent:- the brake pressure is increased if thedriver applies the brakes when the vehi-cle is stationary.

- the seat belts are pre-tensioned.The PRE-SAFE® PLUS braking application iscanceled:Rif the accelerator pedal is depressed whena gear is engagedRif the risk of a collision passes or is no lon-ger detectedRif DISTRONIC PLUS indicates an intentionto pull away

If the hazardous situation passes withoutresulting in an accident, the original settingsare restored.

Automatic measures after an acci-dentImmediately after an accident, the followingmeasures are implemented, depending onthe type and severity of the impact:Rthe hazard warning lamps are activatedRthe emergency lighting is activatedRthe vehicle doors are unlockedRthe front side windows are loweredRthe electrically adjustable steering wheel israisedRthe engine is switched off and the fuel sup-ply is cut offRvehicles with seat belt extenders: the seat-belt buckles for the outer rear seats areilluminated and extend forwards

Child restraint system on the front-passenger seat

General notesAccident statistics show that childrensecured in the rear seats are safer than chil-dren secured in the front-passenger seat. Forthis reason, Mercedes-Benz strongly advisesthat you install the child restraint system on arear seat.If it is absolutely necessary to install a childrestraint system on the front-passenger seat,be sure to observe the instructions and safetynotes on the "OccupantClassificationSystem(OCS)" (Y page 59).You can thus avoid the risks that could ariseas a result of:Ran incorrectly categorized person in thefront-passenger seatRthe unintentional deactivation of the front-passenger front air bagRthe unsuitable positioning of the childrestraint system, e.g. too close to the dash-board

Rearward-facing child restraint systemIf it is absolutely necessary to install a rear-ward-facing child restraint system on thefront-passenger seat, always make sure thatthe front-passenger front air bag is deactiva-ted. Only if the PASSENGER AIR BAG OFFindicator lamp is permanently lit (Y page 50)is the front-passenger front air bag deactiva-ted.

Always observe the child restraint systemmanufacturer's installation and operatinginstructions.

Forward-facing child restraint systemIf it is absolutely necessary to install aforward-facing child restraint system on thefront-passenger seat, always move the front-passenger seat as far back as possible. Fullyretract the seat cushion length. The entirebase of the child restraint system mustalways rest on the seat cushion of the front-passenger seat. The backrest of the childrestraint system must lie as flat as possibleagainst the backrest of the front-passengerseat. The child restraint system must nottouch the roof or be subjected to a load by thehead restraint. Adjust the angle of the seatbackrest and the head restraint positionaccordingly. Alwaysmake sure that the shoul-der belt strap is correctly routed from thevehicle belt outlet to the shoulder belt guideon the child restraint system. The shoulderbelt strapmust be routed forwards and down-wards from the vehicle belt outlet. If neces-sary, adjust the vehicle belt outlet and thefront-passenger seat accordingly.Always observe the child restraint systemmanufacturer's installation and operatinginstructions.

Driving safety systems

Overview of driving safety systemsIn this section, you will find information aboutthe following driving safety systems:RABS (Anti-lock Braking System)(Y page 76)RBAS (Brake Assist System) (Y page 77)RBASPLUS (BrakeAssistSystemPLUS)withCross-Traffic Assist (Y page 77)

RCOLLISION PREVENTION ASSIST PLUS(distance warning function and AdaptiveBrake Assist) (Y page 79)RESP® (Electronic Stability Program)(Y page 81)REBD (Electronic Brake force Distribution)(Y page 83)RADAPTIVE BRAKE (Y page 84)RPRE-SAFE® Brake (Y page 84)RSTEER CONTROL (Y page 86)

Important safety notesIf you fail to adapt your driving style or if youare inattentive, the driving safety systems canneither reduce the risk of an accident noroverride the laws of physics. Driving safetysystems are merely aids designed to assistdriving. You are responsible for maintainingthe distance to the vehicle in front, for vehiclespeed, for braking in good time and for stay-ing in lane. Always adapt your driving style tosuit the prevailing road and weather condi-tions and maintain a safe distance from thevehicle in front. Drive carefully.The driving safety systems described onlywork as effectively as possible when there isadequate contact between the tires and theroad surface. Please pay special attention tothe notes on tires, recommended minimumtire tread depths, etc. (Y page 442).Inwintry driving conditions, always usewintertires (M+S tires) and if necessary, snowchains. Only in this way will the driving safetysystems described in this section work aseffectively as possible.

ABS (Anti-lock Braking System)

General informationABS regulates brake pressure in such a waythat the wheels do not lock when you brake.This allows you to continue steering the vehi-cle when braking.

The!ABSwarning lamp in the instrumentcluster lights up when the ignition is switchedon. It goes out when the engine is running.

Important safety notes

i Observe the "Important safety notes" sec-tion (Y page 76).

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 358) anddisplay messages which may be shown in theinstrument cluster (Y page 317).ABS works from a speed of about 5 mph(8 km/h), regardless of road-surface condi-tions. ABS works on slippery surfaces, evenwhen you only brake gently.

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

X To make a full brake application:depress the 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 indica-tion of hazardous road conditions, and func-tions as a reminder to take extra care whiledriving.

BAS (Brake Assist System)

General informationBAS operates in emergency braking situa-tions. If you depress the brake pedal quickly,BAS automatically boosts the braking force,thus shortening the stopping distance.

Important safety notes

i Observe the "Important safety notes" sec-tion (Y page 76).

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.

BrakingX Keep the brake pedal firmly depressed untilthe emergency braking situation is over.ABS prevents the wheels from locking.

The brakes will function as usual once yourelease the brake pedal. BAS is deactivated.

Distance warning function

Important safety notesi Observe the "Important safety notes" sec-tion for driving safety systems (Y page 76).

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.

FunctionX To activate/deactivate: activate or deac-tivate the distance warning function in theon-board computer (Y page 309).

If the distance warning function is not activa-ted, theæ symbol appears in the assis-tance graphics display.The distancewarning function can help you tominimize the risk of a front-end collision witha vehicle ahead or reduce the effects of sucha collision. If the distance warning functiondetects that there is a risk of a collision, youwill be warned visually and acoustically.

Starting at a speed of around 4mph (7 km/h),the distance warning function warns you ifyou rapidly approach a vehicle in front. Anintermittent warning tone will then sound,and the· distance warning lamp will lightup 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 condi-tions may also cause the system to display awarning.With the help of the radar sensor system, thedistance warning function can detect obsta-cles that are in the path of your vehicle for anextended period of time.Up to a speed of around 44 mph (70 km/h),the distance warning function can also reactto stationary obstacles, such as stopped orparked vehicles.If you approach an obstacle and the distancewarning function detects a risk of a collision,the system will initially alert you both visuallyand acoustically.

If the autonomous braking function requires aparticularly high braking force, preventativepassenger protection measures (PRE-SAFE®)are activated simultaneously.

Adaptive Brake Assist

i Observe the "Important safety notes" sec-tion (Y page 76).

Adaptive Brake Assist provides braking assis-tance in hazardous situations at speedsabove 4 mph (7 km/h). It uses radar sensortechnology to assess the traffic situation.

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. There is arisk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake.

Due to the nature of the system, particularlycomplicated but non-critical driving condi-tions may also cause Brake Assist to inter-vene.If adaptive Brake Assist is not available due toa malfunction in the radar sensor system, the

brake system remains available with fullbrake boosting effect and BAS.With the help of adaptive Brake Assist, thedistance warning signal can detect obstaclesthat are in the path of your vehicle for anextended period of time.If adaptive Brake Assist detects a risk of col-lision with the vehicle in front, it calculatesthe braking force necessary to avoid a colli-sion. If you apply the brakes forcefully, adap-tive Brake Assist will automatically increasethe braking force to a level suitable for thetraffic conditions.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 yourvehicle.

Adaptive Brake Assist is then deactivated.If adaptive Brake Assist demands particularlyhigh braking force, preventative passengerprotection measures (PRE-SAFE®) are activa-ted simultaneously.Up to a speed of approximately 155 mph(250 km/h), adaptive Brake Assist is capableof reacting to moving objects that havealready been detected as such at least onceover the period of observation.Up to a speed of approximately 44 mph(70 km/h), adaptive Brake Assist reacts tostationary obstacles.

If ESP® detects that the vehicle is deviatingfrom the direction desired by the driver, oneor more wheels are braked to stabilize thevehicle. The engine output is also modified tokeep the vehicle on the desired course withinphysical limits. ESP® assists the driver whenpulling away on wet or slippery roads. ESP®can also stabilize the vehicle during braking.

ETS/4ETS (Electronic Traction System)

i Observe the "Important safety notes" sec-tion (Y page 76).

ETS traction control is part of ESP®. On vehi-cles with 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 trans-ferred to the wheel or wheels with traction.Traction control remains active, even if youdeactivate ESP®.

Important safety notes

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.

Vehicles without 4MATIC: observe the noteson ESP® (Y page 437) when towing the vehi-cle with a raised rear axle.ESP® is only deactivated if the å warninglamp is lit continuously.If the ÷ warning lamp lights up continu-ously, ESP® is not available due to a malfunc-tion.Observe the information on warning lamps(Y page 360) and display messages whichmay be shown in the instrument cluster(Y page 317).

Only use wheels with the recommended tiresizes. Only then will ESP® function properly.

Characteristics of ESP®

G WARNINGPRE-SAFE® Brake does not react:Rto small people, e.g. childrenRto animalsRto oncoming vehiclesRto crossing trafficRwhen corneringAs a result, PRE-SAFE® Brake may neithergive warnings nor intervene in all critical sit-uations. There is a risk of an accident.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 isalso impaired in the event of:Rthere is dirt on the sensors or anything elsecovering the sensorsRthere is interference by other radar sourcesRthere are strong radar reflections, forexample in parking garagesRa narrow vehicle traveling in front, e.g. amotorbikeRa vehicle traveling in front on a different linerelative to the center of your vehicle

Recognition by the camera system is alsoimpaired in the event of:Rdirt on the camera or if the camera is cov-eredRthere is glare on the camera system, e.g.from the sun being low in the skyRdarknessRif:

- pedestrians move quickly, e.g. into thepath of the vehicle

- the camera system no longer recognizesa pedestrian as a person due to specialclothing or other objects

- a pedestrian is concealed by otherobjects

- the typical outline of a person is not dis-tinguishable from the background

Following damage to the front end of the vehi-cle, have the configuration and operation ofthe radar sensors checked at a qualified spe-cialist workshop. This also applies to colli-sions at low speeds where there is no visibledamage to the front of the vehicle.Following damage to the windshield, have theconfiguration and operation of the camerasystemchecked at a qualified specialist work-shop.

FunctionX To activate/deactivate: activate or deac-tivate PRE-SAFE® Brake in the on-boardcomputer (Y page 309).If the PRE-SAFE®Brake is not activated, theæ symbol appears in the multifunctiondisplay.

Starting at a speed of around 4mph (7 km/h),this function warns you if you rapidlyapproach a vehicle in front. An intermittentwarning tone will then sound and the·distance warning lamp will light up in theinstrument cluster.X Brake immediately to defuse the situation.orX Take evasive action provided it is safe to doso.

i If there is an increased risk of collision,preventive passenger protection measures(PRE-SAFE®) are activated.

If the risk of collision with the vehicle in frontremains and you do not brake, take evasiveaction or accelerate significantly, the vehiclemay perform automatic emergency braking,up to the point of full brake application. Auto-matic emergency braking is not performeduntil immediately prior to an imminent acci-dent.You can prevent the intervention of the PRE-SAFE® Brake at any time by:Rdepressing the accelerator pedal further.Ractivating kickdown.Rreleasing the brake pedal.

Useful information

i This Operator's Manual describes allmodels and all standard and optional equip-ment of your vehicle available at the time ofpublication of the Operator's Manual.Country-specific differences are possible.Please note that your vehicle may not beequipped with all features described. Thisalso applies to safety-related systems andfunctions.

Exterior lighting

General notesFor reasons of safety, Mercedes-Benz recom-mends that you drive with the lights switchedon even during the daytime. In some coun-tries, operation of the headlamps varies dueto legal requirements and self-imposed obli-gations.

Driving abroad

Symmetrical low-beam headlampsSwitch the headlamps to symmetrical lowbeam in countries in which traffic drives onthe opposite side of the road from the countrywhere the vehicle is registered. This preventsglare to oncoming traffic. When using sym-metrical lights, the edge of the road is not litas widely and as far ahead as normal.Have the headlamps converted at a qualifiedspecialist workshop as close to the border aspossible before driving in these countries.

Asymmetrical low beamHave the headlamps converted back to asym-metrical low-beam headlamps at a qualifiedspecialist workshop as soon as possible aftercrossing the border again.

Setting the exterior lighting

Adaptive Highbeam Assist Plus

General notes

With Adaptive Highbeam Assist Plus, you canautomatically switch between low-beam, par-tial high-beam and high-beam headlamps.Partial high-beam is a form of illuminationwhereby the high-beam is directed past otherroad users. Other road users are kept out ofthe high-beam. This prevents glare. Whenthere is a vehicle in front, for example, thehigh-beam headlamps illuminate the areas toits right and left, and the vehicle in front isilluminated by the low-beam headlamps.The system automatically adapts the low-beam headlamp range depending on the dis-tance to the other vehicle. Once the systemno longer detects any other vehicles, it reac-tivates the high-beam headlamps.If the high-beam or partial high-beam arecausing too much reflection from trafficsigns, the lights are automatically dimmedand glare for the driver caused by the reflec-tions is thus avoided.The system's optical sensor is located behindthe windshield near the overhead controlpanel.

Important safety notes

G WARNINGAdaptive Highbeam Assist Plus does not rec-ognize road users:Rwho have no lights, e.g. pedestriansRwho have poor lighting, e.g. cyclistsRwhose lighting is blocked, e.g. by a barrierIn very rare cases, Adaptive Highbeam AssistPlus may not recognize road users who dohave lights, or may recognize them too late. Inthis or similar situations, the automatic high-beam headlamps will not be deactivated orwill be activated regardless. There is a risk ofan accident.Always carefully observe the traffic conditionsand switch off the high-beam headlamps ingood time.

Adaptive Highbeam Assist Plus cannot takeinto account road, weather or traffic condi-tions. Adaptive Highbeam Assist Plus is onlyan aid. You are responsible for adjusting thevehicle's lighting to the prevailing light, visi-bility and traffic conditions.In particular, the detection of obstacles canbe restricted if there is:Rpoor visibility, e.g. due to fog, heavy rain orsnowRdirt on the sensors or the sensors areobscured

Replacing bulbs

The front and rear light clusters of your vehi-cle are equipped with LED light bulbs. Do notreplace the bulbs yourself. Contact a qualifiedspecialist workshop which has the necessaryspecialist knowledge and tools to carry outthe work required.Lamps are an important aspect of vehiclesafety. You must therefore make sure thatthese function correctly at all times. Have theheadlamp setting checked regularly.

Windshield wipers

Switching the windshield wiperson/off! Do not operate the windshield wiperswhen the windshield is dry, as this coulddamage the wiper blades. Moreover, dustthat has collected on the windshield canscratch the glass if wiping takes placewhenthe windshield is dry.If it is necessary to switch on thewindshieldwipers in dry weather conditions, alwaysuse washer fluid when operating the wind-shield wipers.

! If the windshield wipers leave smears onthe windshield after the vehicle has beenwashed in an automatic car wash, wax orother residues may be the reason for this.Clean the windshield using washer fluidafter washing the vehicle in an automaticcar wash.

! Vehicles with a rain sensor: if the wind-shield becomes dirty in dry weather condi-tions, the windshield wipers may be activa-ted inadvertently. This could then damagethe windshield wiper blades or scratch thewindshield.For this reason, you should always switchoff the windshield wipers in dry weather.

Useful information

i This Operator's Manual describes allmodels and all standard and optional equip-ment of your vehicle available at the time ofpublication of the Operator's Manual.Country-specific differences are possible.Please note that your vehicle may not beequipped with all features described. Thisalso applies to safety-related systems andfunctions.

i Read the information on qualified special-ist workshops (Y page 29).

Overview of climate control systems

General notesObserve the settings recommended on thefollowing pages. The windows could other-wise fog up.To prevent the windows from fogging up:Rswitch off climate control only brieflyRswitch on air-recirculation mode onlybrieflyRswitch on the cooling with air dehumidifi-cation functionRswitch on the defrost windshield functionbriefly, if required

Climate control regulates the temperatureand air humidity in the vehicle interior. The airfilter cleans the air, thus improving the inte-rior climate.The "Cooling with air dehumidification" func-tion is only available when the engine is run-ning. Optimum climate control is only ach-ieved with the side windows and roof closed.The residual heat function can only be acti-vated or deactivated with the ignitionswitched off (Y page 177).

i Ventilate the vehicle for a brief periodduring warm weather, e.g. using the con-venience opening feature (Y page 107).This will speed up the cooling process and

the desired interior temperature will bereached more quickly.

i The integrated filter filters out most par-ticles of dust and soot and completely fil-ters out pollen. It also reduces gaseous pol-lutants and odors. A clogged filter reducesthe amount of air supplied to the vehicleinterior. For this reason, you should alwaysobserve the interval for replacing the filter,which is specified in the MaintenanceBooklet. As it depends on environmentalconditions, e.g. heavy air pollution, theinterval may be shorter than stated in theMaintenance Booklet.

i It is possible that the blower may be acti-vated automatically 60 minutes after theSmartKey has been removed depending onvarious factors, e.g. the outside tempera-ture. The vehicle is then ventilated for30 minutes to dry the climate control sys-tem.

Notes on breaking-in a new vehicle

Important safety notesThe sensor system of some driving and driv-ing safety systems adjusts automaticallywhile a certain distance is being driven afterthe vehicle has been delivered or afterrepairs. Full system effectiveness is notreached until the end of this teach-in proce-dure.New and replaced brake pads and discs onlyreach their optimum braking effect after sev-eral hundred kilometers of driving. Compen-sate for this by applying greater force to thebrake pedal.

The first 1000 miles (1500 km)The more you look after the engine when it isnew, the more satisfied you will be with itsperformance in the future.RYou should therefore drive at varying vehi-cle and engine speeds for the first1000 miles (1500 km).RAvoid heavy loads, e.g. driving at full throt-tle, during this period.RWhen shifting gears manually, upshift ingood time, before the tachometer needlereachesÔ of the way to the red area of thetachometer.

RDo not manually shift to a lower gear tobrake the vehicle.RTry to avoid depressing the acceleratorpedal beyond the point of resistance (kick-down).RAll vehicles (except AMG vehicles): ide-ally, for the first 1,000 miles (1,500 km),drive in program E.

Additional breaking-in notes for AMG vehi-cles:RDo not drive faster than 85 mph(140 km/h) for the first 1,000 miles(1,500 km).ROnly allow the engine to reach a maximumengine speed of 4,500 rpm briefly.RChange gear in good time.RIdeally, for the first 1,000miles (1,500 km),drive in program C.

After 1000miles (1500 km), you can increasethe engine speed gradually and acceleratethe vehicle to full speed.You should also observe these notes onbreaking in if the engine or parts of the drivetrain on your vehicle have been replaced.Always observe the respective speed limits.

Driving

Important safety notes

G WARNINGObjects in the driver's footwell can restrict thepedal travel or obstruct a depressed pedal.The operating and road safety of the vehicle isjeopardized. There is a risk of an accident.Make sure that all objects in the vehicle arestowed correctly, and that they cannot enterthe driver's footwell. Install the floormatssecurely and as specified in order to ensuresufficient clearance for the pedals. Do not useloose floormats and do not place floormats ontop of one another.

G WARNINGUnsuitable footwear can hinder correct usageof the pedals, e.g.:Rshoes with thick solesRshoes with high heelsRslippersThere is a risk of an accident.Wear suitable footwear to ensure correctusage of the pedals.

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

G WARNINGIf the parking brake has not been fullyreleased when driving, the parking brake can:Roverheat and cause a fireRlose its hold function.There is a risk of fire and an accident. Releasethe parking brake fully before driving off.

! Do not warm up the engine with the vehi-cle stationary. Drive off immediately. Avoidhigh engine speeds and driving at full throt-tle until the engine has reached its operat-ing temperature.Only shift the automatic transmission tothe desired drive position when the vehicleis stationary.Where possible, avoid spinning the drivewheels when pulling away on slipperyroads. You could otherwise damage thedrive train.

! AMG vehicles: at low engine oil temper-atures below 68 ‡ (+20 †), the maximumengine speed is restricted in order to pro-tect the engine. To protect the engine and

maintain smooth engine operation, avoiddriving at full throttle when the engine iscold.

Pulling away

General notes

G WARNINGIf the engine speed is above the idling speedand you engage transmission position D or R,the vehicle could pull away suddenly. There isa risk of an accident.When engaging transmission position D or R,always firmly depress the brake pedal and donot simultaneously accelerate.

Depress the accelerator carefully when pull-ing away.The vehicle locks centrally once you havepulled away. The locking knobs in the doorsdrop down.You can open the doors from the inside at anytime.You can also deactivate the automatic lockingfeature (Y page 98).It is only possible to shift the transmissionfrom position P to the desired position if youdepress the brake pedal. Only then is theparking lock released. If the brake pedal is notdepressed, the DIRECT SELECT lever can stillbe moved but the parking lock remainsengaged.

i Upshifts take place at higher enginespeeds after a cold start. This helps thecatalytic converter to reach its operatingtemperature more quickly.

Driving tips

General driving tips

Important safety notes

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 considerablymore 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 coun-try in which you are driving. Some jurisdic-tions prohibit the driver from using a mobilephone while driving a vehicle.If you make a call while driving, always usehands-freemode. 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 coversa distance of 44 ft (approximately 14 m) persecond.

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

X Remove unnecessary loads.X Remove roof racks when they are not nee-ded.

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 theMaintenance Booklet or by the serviceinterval display.

Fuel consumption also increases when driv-ing in cold weather, in stop-start traffic and inhilly terrain.

Drinking and driving

G WARNINGDrinking and driving and/or taking drugs anddriving are very dangerous combinations.Even a small amount of alcohol or drugs canaffect 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

G WARNINGCombustion engines emit poisonous exhaustgases such as carbon monoxide. Inhalingthese exhaust gases leads to poisoning. Thereis a risk of fatal injury. Therefore never leavethe engine running in enclosed spaces with-out sufficient ventilation.

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 withthe manufacturer's specifications. For thisreason, all work on the enginemust be carriedout by qualified and authorized Mercedes-Benz technicians.The engine settings must not be changedunder any circumstances. Furthermore, allspecific service work must be carried out at

regular intervals and in accordance with theMercedes-Benz service requirements. Detailscan be found in the Maintenance Booklet.

ECO display

The ECO display provides feedback on howeconomical your driving characteristics are.The ECO display assists you in achieving themost economical driving style for the selec-ted settings and prevailing conditions. Yourdriving style can significantly influence thevehicle's consumption.The ECO display consists of three bars:RAccelerationAccelerationRConstantConstantRCoastingCoastingThe percent value is the average value of thethree bars. The three bars and themean valuebegin at the value of 50%. A higher percent-age indicates a more economical drivingstyle.The ECO display does not indicate the actualfuel consumption. A fixed percentage countin the ECO display does not indicate a fixedconsumption.Apart from driving style, consumption isdependent on many factors such as, e.g.:RloadRtire pressureRcold startRchoice of routeRelectrical consumers switched on

These factors are not included in the ECO dis-play.The evaluation of your driving style is carriedout using the following three categories:RAccelerationAcceleration (evaluation of all accelera-tion processes):- The bar fills up: moderate acceleration,especially at higher speeds

- The bar empties: sporty accelerationRConstantConstant (assessment of driving behaviorat all times):- The bar fills up: constant speed andavoidance of unnecessary accelerationand deceleration

- The bar empties: fluctuations in speedRCoastingCoasting (assessment of all decelerationprocesses):- The bar fills up: anticipatory driving,keeping your distance and early releaseof the accelerator. The vehicle can coastwithout use of the brakes.

- The bar empties: frequent brakingAn economical driving style specially requiresdriving at moderate engine speeds.To achieve a higher value in the categoriesAccelerationAcceleration and ConstantConstant:Robserve the gearshift recommendations.Rdrive in drive program E.On long journeys at a constant speed, e.g. onthe highway, only the bar for ConstantConstant willchange.The ECO display summarizes the driving char-acteristics from the start of the journey to itscompletion. For this reason, the bars changedynamically at the beginning of the journey.On longer journeys, there are fewer changes.For more dynamic changes, carry out a man-ual reset.For further information on the ECO display,see (Y page 300).

Braking

Important safety notes

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 shiftingearly to a lower gear. This allows you to takeadvantage of the engine braking effect andhelps avoid overheating and excessivewear of the brakes.When you take advantage of the enginebraking effect, a drive wheel may not turnfor some time, e.g. on a slippery road sur-face. This could cause damage to the drivetrain. This type of damage is not covered bythe Mercedes-Benz warranty.

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.Drive on for a short while. This allows the air-flow to cool the brakes more quickly.

Wet roadsIf you have driven for a long time in heavy rainwithout braking, theremay be a delayed reac-tion from the brakeswhen braking for the firsttime. Thismay 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 vehi-cle washed, brake firmly while paying atten-tion to the traffic conditions. Thiswill warmupthe brake discs, thereby drying them morequickly and protecting them against corro-sion.

Limited braking performance on salt-treated roadsIf you drive on salted roads, a layer of saltresidue may form on the brake discs andbrake pads. This can result in a significantlylonger braking distance.RIn order to prevent any salt build-up, applythe brakes occasionally while paying atten-tion to the traffic conditions.RCarefully depress the brake pedal and thebeginning and end of a journey.RMaintain a greater distance to the vehicleahead.

Servicing the brakes

! If the red brake warning lamp lights up inthe instrument cluster and you hear awarn-ing tone while the engine is running, thebrake fluid level may be too low. Observeadditional warning messages in the multi-function display.The brake fluid level may be too low due tobrake pad wear or leaking brake lines.Have the brake system checked immedi-ately. This work should be carried out at aqualified specialist workshop.

! Vehicles with 4MATIC: function or per-formance tests may only be carried out on

a 2-axle dynamometer. If you wish to oper-ate the vehicle on such a dynamometer,please consult an authorized Mercedes-Benz Center in advance. You could other-wise damage the drive train or the brakesystem.

! Vehicleswith 4MATIC: the ESP® systemoperates automatically. The engine and theignitionmust therefore be switched off (theSmartKey must be in position 0 or 1 in theignition lock or the Start/Stop button mustbe in position 0 or 1) if the electric parkingbrake is tested on a brake dynamometer.Braking triggered automatically by ESP®may cause severe damage to the brakesystem.

! Vehicles without 4MATIC: the ESP®system operates automatically. The engineand the ignitionmust therefore be switchedoff (the SmartKeymust be in position0 or1in the ignition lock or the Start/Stop buttonmust be in position 0 or 1) if:Rthe electric parking brake is tested usinga brake dynamometer.Rthe vehicle is towed with one axle raised.Braking triggered automatically by ESP®may cause severe damage to the brakesystem.

All checks and maintenance work on thebrake system must be carried out at a quali-fied specialist workshop. Consult a qualifiedspecialist workshop to arrange this.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 function-ality of your brakes at regular intervals.Information on BAS (Brake Assist) (Y page 77)and BAS PLUS (Brake Assist PLUS)(Y page 77).

For safety reasons, Mercedes-Benz recom-mends only installing the following brakedisks and brake pads/linings:Rbrake disks that have been approved byMercedes-BenzRbrake pads/linings that have beenapproved by Mercedes-Benz or that are ofan equivalent standard of quality

Other brake disks or brake pads/linings cancompromise the safety of your vehicle.Always replace all brake disks and brakepads/linings on an axle at the same time.Always install new brake pads/linings whenreplacing brake disks.The vehicle is equipped with lightweightbrake disks to which the wheel assembly withrim and threaded connection is matched.The use of brake disks other than thoseapproved by Mercedes-Benz can change thetrackwidth and is subject to approval, if appli-cable.Shock-type loads when handling the brakedisks, such as when changing wheels, canlead to a reduction in comfort when drivingwith lightweight brake disks. Avoid shock-type loads on the lightweight brake disks,particularly on the brake plate.Mercedes-Benz recommends that you onlyuse brake fluid that has been speciallyapproved for your vehicle by Mercedes-Benz,or which corresponds to an equivalent qualitystandard. Brake fluid which has not beenapproved for Mercedes-Benz vehicles orwhich is not of an equivalent quality couldaffect your vehicle's operating safety.

The AMG brake systems are designed forheavy loads. This may lead to noise whenbraking. This will depend on:RspeedRbraking forceRenvironmental conditions, such as temper-ature and humidity

The wear of individual components of thebrake system, such as the brake pads/liningsor brake discs, depends on the individual driv-ing style and operating conditions.For this reason, it is impossible to state amileage that will be valid under all circum-stances. An aggressive driving style will leadto high wear. You can obtain further informa-tion about this from your authorizedMercedes-Benz Center.New and replaced brake pads and discs onlyreach their optimum braking effect after sev-eral hundred kilometers of driving. Compen-sate for this by applying greater force to thebrake pedal. Keep this in mind, and adaptyour driving and braking accordingly duringthis break-in period.Excessive heavy braking results in corre-spondingly high brake wear. Observe thebrake wear warning lamp in the instrumentcluster and note any brake status messagesin the multifunction display. Especially forhigh performance driving, it is important tomaintain and have the brake system checkedregularly.

Driving on wet roads

HydroplaningIf water has accumulated to a certain depthon the road surface, there is a danger ofhydroplaning occurring, even if:Ryou drive at low speeds.Rthe tires have adequate tread depth.

For this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:Rlower your speed.Ravoid ruts.Ravoid sudden steering movements.Rbrake carefully.

Driving on flooded roads

! Do not drive through flooded areas.Check the depth of anywater before drivingthrough it. Drive slowly through standingwater. Otherwise, water may enter thevehicle interior or the engine compartment.This can damage the electronic compo-nents in the engine or the automatic trans-mission. Water can also be drawn in by theengine's air suction nozzles and this cancause engine damage.

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. There is a risk offatal injury.If you leave the engine or the auxiliary heatingrunning, make sure the exhaust pipe and areaaround the vehicle are clear of snow. Toensure an adequate supply of fresh air, open awindow on the side of the vehicle that is notfacing into the wind.

Have your vehicle winterproofed at a qualifiedspecialist workshop at the onset of winter.Drive particularly carefully on slippery roadsurfaces. Avoid sudden acceleration, steeringand brakingmaneuvers. Do not use the cruisecontrol or DISTRONIC PLUS.If the vehicle threatens to skid or cannot bestopped when moving at low speed:X Shift the transmission to position N.The outside temperature indicator is notdesigned to serve as an ice-warning deviceand is therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.Indicated temperatures just above the freez-ing point do not guarantee that the road sur-face is free of ice. The road may still be icy,especially in wooded areas or on bridges.You should pay special attention to road con-ditions when temperatures are around freez-ing point.For more information on driving with snowchains, see (Y page 445).For more information on driving with summertires, see (Y page 444).Observe the notes in the "Winter operation"section (Y page 444).

Further information on driving safety systems(Y page 76).

Cruise control

General notesCruise control maintains a constant roadspeed for you. It brakes automatically in orderto avoid exceeding the set speed. Change intoa lower gear in good time on long and steepdownhill gradients. This is especially impor-tant if the vehicle is laden. By doing so, youwill make use of the braking effect of theengine. This relieves the load on the brakesystem and prevents the brakes from over-heating and wearing too quickly.Use cruise control only if road and traffic con-ditions make it appropriate to maintain asteady speed for a prolonged period. You canstore any road speed above 20 mph(30 km/h).

Important safety notesIf you fail to adapt your driving style, cruisecontrol can neither reduce the risk of an acci-dent nor override the laws of physics. Cruisecontrol cannot take into account the road,traffic and weather conditions. Cruise controlis only an aid. You are responsible for the dis-tance to the vehicle in front, for vehicle speed,for braking in good time and for staying inyour lane.Do not use cruise control:Rin road and traffic conditions which do notallow you to maintain a constant speed e.g.in heavy traffic or on winding roadsRon slippery road surfaces. Braking or accel-erating could cause the drivewheels 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.

Change into a lower gear in good time on longand steep downhill gradients. This is espe-cially important if the vehicle is laden. Bydoing so, you will make use of the brakingeffect of the engine. This relieves the load onthe brake system and prevents the brakesfrom overheating and wearing too quickly.If DISTRONIC PLUS detects that there is a riskof a collision, you will be warned visually andacoustically. DISTRONIC PLUS cannot pre-vent a collision without your intervention. Anintermittent warning tone will then sound andthe distance warning lamp will light up in theinstrument cluster. Brake immediately inorder to increase the distance to the vehiclein front or take evasive action provided it issafe to do so.DISTRONIC PLUS operates in range between0 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 theresponsible authorities. You can refer to therelevant chapter in the Operator's Manual ifquestions are asked about this.

Cornering, going into and coming out of abend

The ability of DISTRONIC PLUS to detect vehi-cles when cornering is limited. Your vehiclemay brake unexpectedly or late.

Vehicles traveling on a different line

DISTRONIC PLUS may not detect vehiclestraveling on a different line. The distance tothe vehicle in front will be too short.

Other vehicles changing lanes

DISTRONIC PLUS has not detected the vehi-cle cutting in yet. The distance to this vehiclewill be too short.

Narrow vehicles

DISTRONIC PLUS has not yet detected thevehicle in front on the edge of the road,because of its narrow width. The distance tothe vehicle in front will be too short.

Obstructions and stationary vehicles

DISTRONIC PLUS does not brake for obsta-cles or stationary vehicles. If, for example, thedetected vehicle turns a corner and revealsan obstacle or stationary vehicle, DISTRONICPLUS will not brake for these.

DISTRONIC PLUS with Steering Assistand Stop&Go Pilot

General notes

DISTRONIC PLUS with Steering Assist andStop&Go Pilot aids you in keeping the vehiclein the center of the driving lane by means ofmoderate steering interventions at speeds of0 - 125 mph (0 - 200 km/h).It monitors the area in front of your vehicle bymeans of camera system: at the top of thewindshield.At speeds of 0 - 37 mph (0 - 60 km/h),Stop&Go Pilot focuses on the vehicle in front,taking into account lane markings, e.g. whenfollowing vehicles in a traffic jam.At speeds of more than 37 mph (60 km/h)Steering Assist focuses on detected lane

markings (left and right), and only on the vehi-cle in front if lane markings are missing.Steering Assist and Stop&Go Pilot do not pro-vide any support if these conditions do notexist.DISTRONIC PLUS must be active in order forthe function to be available.

Important safety notesIf you fail to adapt your driving style,DISTRONIC PLUS with Steering Assist andStop&Go Pilot can neither reduce the risk ofan accident nor override the laws of physics.It cannot take account of road, weather andtraffic conditions. DISTRONIC PLUS withSteering Assist and Stop&Go Pilot is only anaid. You are responsible for the distance tothe vehicle in front, for vehicle speed, forbraking in good time and for staying in yourlane.DISTRONIC PLUS with Steering Assist andStop&Go Pilot does not detect road and traf-fic conditions. If you are following a vehiclewhich is driving towards the edge of the road,your vehicle could come into contact with thecurb or other road boundaries. Be particularlyaware of other road users, e.g. cyclists, thatare directly next to your vehicle.Obstacles such as building site huts on thelane or projecting out into the lane are notdetected.An inappropriate steering intervention, e.g.after intentionally driving over a lanemarking,can be corrected at any time if you steerslightly in the opposite direction.DISTRONIC PLUS with Steering Assist andStop&Go Pilot cannot continuously keep yourvehicle in lane. In some cases, the steeringintervention is not sufficient to bring the vehi-cle back to the lane. In such cases, you muststeer the vehicle yourself to ensure that itdoes not leave the lane.

4MATIC (permanent four-wheel drive)4MATIC ensures that all four wheels are per-manently driven. Together with ESP®, itimproves the traction of your vehicle when-ever a drive wheel spins due to insufficientgrip.

If you fail to adapt your driving style, 4MATICcan neither reduce the risk of accident noroverride the laws of physics. 4MATIC cannottake account of road, weather and traffic con-ditions. 4MATIC is only an aid. You areresponsible for the distance to the vehicle infront, for vehicle speed, for braking in goodtime and for staying in your lane.If a drive wheel spins due to insufficient grip:ROnly depress the accelerator pedal as far asnecessary when pulling away.RAccelerate less when driving.

! Never tow the vehicle with one axleraised. This may damage the transfer case.Damage of this sort is not covered by theMercedes-Benz Limited Warranty. Allwheelsmust remain either on the ground orbe fully raised. Observe the instructions fortowing the vehicle with all wheels in fullcontact with the ground.

i In wintry driving conditions, themaximumeffect of 4MATIC can only be achieved ifyou use winter tires (M+S tires), with snowchains if necessary.

PARKTRONIC

Important safety notesPARKTRONIC is an electronic parking aid withultrasonic sensors. It monitors the areaaround your vehicle using six sensors in thefront bumper and six sensors in the rearbumper. PARKTRONIC indicates visually andaudibly the distance between your vehicleand an object.PARKTRONIC is only an aid. It is not a replace-ment for your attention to your immediatesurroundings. You are always responsible forsafe maneuvering, parking and exiting a park-ing space.

Parking tips:ROn narrow roads, drive as close to the park-ing space as possible.RParking spaces that are littered or over-grown might be identified or measuredincorrectly.RParking spaces that are partially occupiedby trailer drawbars might not be identifiedas such or be measured incorrectly.RSnowfall or heavy rainmay lead to a parkingspace being measured inaccurately.RPay attention to the PARKTRONIC(Y page 250) warning messages during theparking procedure.RYou can intervene in the steering procedureto correct it at any time. Active ParkingAssist will then be canceled.RWhen transporting a load which protrudesfrom your vehicle, you should not useActive Parking Assist.RNever use Active Parking Assist when snowchains are installed.RMake sure that the tire pressures arealways correct. This has a direct influenceon the parking characteristics of the vehi-cle.

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

Detecting parking spacesObjects located above the height range ofActive Parking Assist will not be detectedwhen the parking space is measured. Theseare not taken into account when the parkingprocedure is calculated, e.g. overhangingloads, tail sections or loading ramps of goodsvehicles.

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 there are objects above the detection range,stop and deactivate Active Parking Assist.

For further information on the detectionrange (Y page 249).Active Parking Assist does not assist youparking in spaces at right angles to the direc-tion of travel if:Rtwo parking spaces are located directlynext to one anotherRthe parking space is directly next to a lowobstacle such as a low curbRyou park forwardsActive Parking Assist does not assist youparking in spaces that are parallel or at rightangles to the direction of travel if:Rthe parking space is on a curbRthe system reads the parking space asbeing blocked, for example by foliage orgrass paving blocksRthe area is too small for the vehicle tomaneuver intoRthe parking space is bordered by an obsta-cle, e.g. a tree, a post or a trailer

Driving Assistance PLUS package

General notesThe Active Driving Assistance PLUS packageconsists of DISTRONIC PLUS (Y page 231),Active Blind Spot Assist (Y page 270) andActive Lane Keeping Assist (Y page 273).

Active Blind Spot Assist

General notesActive Blind Spot Assist uses a radar sensorsystem, pointed toward the rear of the vehi-cle, to monitor the area to the sides of thevehicle which the driver is unable to see. Awarning display in the exterior mirrors drawsyour attention to vehicles detected in themonitored area. If you then switch on the cor-responding turn signal to change lanes, youwill also receive a visual and audible collisionwarning. If a risk of lateral collision is detec-

ted, corrective braking may help you avoid acollision. Before a course-correcting brakeapplication, Active Blind Spot Assist evalu-ates the space in the direction of travel and atthe sides of the vehicle. For this, Active BlindSpot Assist uses radar sensors which arepointed in the direction of travel.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 isnot a 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

Active Lane Keeping Assist

General notes

Active Lane Keeping Assist monitors the areain front of your vehicle by means of camerasystem: at the top of the windshield. Vari-ous different areas to the front, rear and sideof your vehicle are alsomonitoredwith the aidof the radar sensor system. Active Lane Keep-ing Assist detects lane markings on the roadand can warn you before you leave your laneunintentionally. If you do not react to thewarning, a lane-correcting application of thebrakes can bring the vehicle back into theoriginal lane.If you select kmkm in the Display UnitDisplay UnitSpeed-/Odometer:Speed-/Odometer: function on the on-boardcomputer (Y page 312), Active Lane KeepingAssist is activated starting at a speed of60 km/h. If the milesmiles display unit is selected,the assistance range begins at 40 mph.

Important safety notesIf you fail to adapt your driving style, ActiveLane Keeping Assist can neither reduce therisk of accident nor override the laws of phys-ics. Active Lane Keeping Assist cannot takeaccount of road and weather conditions. Itmay not recognize traffic situations. ActiveLane Keeping Assist is only an aid. You areresponsible for the distance to the vehicle infront, for vehicle speed, for braking in goodtime and for staying in your lane.Active Lane Keeping Assist cannot continu-ously keep your vehicle in its lane.

PLUG-IN HYBRID operation

Points to remember

General notesHybrid technology combines a fuel efficientinternal combustion engine with a powerfulelectric motor. In HYBRID mode, the hybridsystem automatically selects the most effi-cient operating mode for every driving situa-tion. Drive the vehicle in the usual manner.To save fuel, in HYBRID mode, the hybridsystem switches off the combustion engineas often as possible during the journey whenpower output requirements are low. Whenpower output requirements are low, the elec-tric motor powers the vehicle. The engine isswitched on, even while the vehicle is inmotion, when a higher power output isrequired. The engine is usually switched off

when the vehicle is stationary. Consequently,there is usually no engine idling as with com-bustion engine vehicles.For pulling away and accelerating, the electricmotor supports the internal combustionengine using the power stored in the high-voltage battery. This energy is also used fordriving in partially electric mode, to operatethe electric refrigerant compressor and sup-port the 12 V on-board electrical system. Inthis way the hybrid drive helps to reduce yourvehicle's fuel consumption.Observe the driving tips on PLUG-IN HYBRIDoperation (Y page 287).

Recuperative Brake SystemIf you release the accelerator pedal when thevehicle is in motion, overrun recuperation isinitiated. The electric motor is operated as agenerator when in overrun mode and whenyou brake. Hybrid technology converts thekinetic energy of the vehicle into electricityand stores it in the high-voltage battery.Observe the important safety notes for theRecuperative Brake System (Y page 48).

Important safety notesIf the engine is switched off by the ECO start/stop function and you open the driver's door:Ramessage appears in themultifunction dis-play andRa warning tone soundsFurther information (Y page 340).All of the vehicle's systems remain active, if:Rthe vehicle is stationaryRthe combustion engine is switched off andRthe READY indicator in the instrument clus-ter lights up

If you remove your foot from the brake pedalwhile in transmission position D or R, thevehicle may pull away automatically.Observe the notes on the READY display ofthe ECO start/stop function (Y page 288).

Vehicles with an electric motor generatemuch less driving noise than vehicles withinternal combustion engines. As a result, yourvehicle may not be heard by other road usersin certain situations.Depending on the vehicle's equipment andcountry-specific regulations, the vehicle canbe equippedwith Acoustic Vehicle Indication.Acoustic Vehicle Indication generates a cer-tain sound at a speed between 0 and 20 mph(30 km/h). This helps other road users, par-ticularly pedestrians and cyclists, to hear yourvehicle better. The sound can also be heardinside the vehicle.The volume depends on the engine speed.The faster you accelerate, the louder thesound is. At a speed of over 20 mph(30 km/h) the sound is switched off. Abovethis speed, the natural sounds from the vehi-cle are sufficient that it can be heard in goodtime by other road users.

Haptic accelerator pedal

General notesThe haptic accelerator pedal helps you toreduce the fuel consumption and emissionsof your vehicle.There are two different functions available forthis purpose:Ran additional point of resistance inE-MODEoperating mode (Y page 280)Ra double impulse in E+ operating mode(Y page 285)

Page 289: S-Class - Mercedes-Benz USA · 2020-01-16 · S-Class Operator'sManual Orderno.6515254413 Partno.2225840803 EditionC2015 É2225840803IËÍ 2225840803 S-ClassOperator'sManual

Additional point of resistance in the hap-tic accelerator pedalThe maximum available electric performanceis indicated by a tangible point of resistancein the haptic accelerator pedal.The additional point of resistance is availablein E-MODE operating mode (Y page 280)If you depress the haptic accelerator pedalbeyond the pressure point, the combustionengine is switched on.

Double pulses in the haptic acceleratorpedalA tangible double pulse in the haptic acceler-ator pedal gives you a recommendation torelease the accelerator pedal. By this means,in HYBRID, E-MODE or E-SAVE operatingmode the combustion engine can be switchedoff and disconnected from the power train(overrun mode).The double pulse is available in drive programE+ (Y page 285).After the accelerator pedal has beenreleased, the coasting characteristics of thevehicle are adapted to the traffic conditions.To avoid getting too close to the vehicle infront, you must apply the brakes manuallywhen necessary.

Driving tips

General driving tipsDrive carefully and maintain a safe distancefrom the vehicle in front. Avoid frequent andsudden acceleration as well as abrupt brak-ing.During partial electric driving, pulling awayand acceleration, the electric motor supportsthe internal combustion engine.During overrun in transmission positionD andbraking, the electric motor will operate as agenerator.Further information on the ECO start/stopfunction (Y page 288).Additional driving tips (Y page 224).

Stationary vehicleIf the vehicle is stopped, the combustionengine is, for the most part, switched off.Automatic climate control continues to func-tion. The electromechanically assisted steer-ing gear allows you to use the power steeringwithout reduced comfort.

AccelerationDepending on the operating mode, pullingaway and driving under low load conditionsare performed:Rentirely by electric propulsionRin combination with the internal combus-tion engine

When accelerating at an increased or fullload, boost mode is utilized. The electricmotor supports the internal combustionengine by providing additional torque whenthe accelerator is depressed rapidly.

Overrun mode or brakingThere are three possible operating modeswhen the hybrid vehicle is decelerating:Renergy recovery takes place even when thevehicle is decelerating purely in overrunmode (Y page 276). The electric motoroperates as a generator and stores therecovered energy in the high-voltage bat-tery.Rwhen the brakes are applied lightly, thevehicle is slowed down further by the elec-tric motor. This increases the energy recov-ery taking place (Y page 276). The electricmotor operates as a generator and storesthe recovered energy in the high-voltagebattery.Rwhen the brakes are applied with greaterforce, the service brakes are also used toslow the vehicle down. The two systemswork together.

Urban drivingEnergy is recuperated during frequent decel-eration and stopping in city traffic.

The vehicle can be driven by the electricmotor alone up to a speed of approximately130 km/h.The vehicle is driven by the electric motoralone only when all conditions for the auto-matic engine switch-off are fulfilled.Further information on the automatic engineswitch-off (Y page 288).

Driving on inter-urban roadsThe following phases are possible when driv-ing on inter-urban roads:Rrapid acceleration (boost mode)Rconstant energy consumptionRenergy recuperationRelectric operation modeA great deal of recovered energy may beavailable, depending on the route profile. Thisreduces consumption and emissions.

Highway drivingDuring highway driving, fuel consumption andemissions are favorably influenced in partic-ular by reduced power losses.The internal combustion engine will beswitched off automatically, if:Rthe driver removes his foot from the accel-erator pedal in drive program E and a speedof 130 km/h is not exceededRthe driver removes his foot from the accel-erator pedal in drive program E+ and aspeed of 180 km/h is not exceeded.

Further information on the automatic engineswitch-off (Y page 288).

ECO start/stop function

General notesThe ECO start/stop function switches theinternal combustion engine off automaticallywhen the vehicle stops moving and at highspeeds (Y page 289).All vehicle systems remain active, e.g. theautomatic climate control.

The ECO start/stop function is only availablein drive programs E and E+. Electric-onlyoperation is only possible in drive programs Eand E+. Additional information for drive pro-grams E and E+ (Y page 285).

Automatic engine switch-offThe engine is switched off automatically,including when:Rthe driver removes his foot from the accel-erator in drive program E and a speed of130 km/h is not exceeded (Y page 289)Rthe driver removes his foot from the accel-erator in drive program E+ and a speed of180 km/h is not exceeded (Y page 289)Rthe engine has reached its operating tem-peratureRthe driver’s seat belt is fastened and thedriver’s door is closedRthe driver only slightly depresses the accel-erator pedal in order to, for example, main-tain the current speed for a limited distanceRthe hood is closed and engaged properlyRthe high-voltage battery is charged suffi-cientlyRthere are nomalfunctions in the hybrid sys-tem

The internal combustion engine will not beswitched off automatically, if:Rthe self-diagnosis function of the enginecontrol unit is still activeRthere is a malfunction in the hybrid systemRthe climate control of the vehicle requires itRthe high-voltage battery is being charged(Y page 282)Rautomatic emissions tests are running

Automatic engine startThe automatically switched-off internal com-bustion engine starts automatically in certainsituations, if:Rthe power demand from the driver via theaccelerator pedal is greater than the elec-tric motor alone can provideRthe driver switches to drive program S orMRthe condition of charge of the high-voltagebattery has reached the lower limitRthe settings of the automatic climate con-trol require it, e.g. at external temperaturesabove 30 †

Overrun modeIn overrun mode, the combustion engine isswitched off and is disconnected from thedrive train. The electric motor:Rgenerates low thrust, which corresponds tothe overrun mode of an active combustionengineRfunctions as a generator and produces thenecessary energy for the auxiliary consum-ers and charges the high-voltage battery

Overrun mode is possible in the followingspeed range:Rin drive program E below 130 km/hRin drive program E+ below 180 km/hIn drive program E+, after the acceleratorpedal has been released the coasting char-acteristics of the vehicle are adapted to thetraffic conditions. Further information aboutthe haptic accelerator pedal (Y page 286).

Map-based energy managementFor map-based energy management, the sys-tem factors in information about the expec-ted route when route guidance is active.The information on the route is provided byCOMAND and includes the following:Rroad categoriesRspeed limitationsRdata on downhill gradients

The use of electric energy is automaticallyoptimally distributed from the beginning tothe end of the journey, using informationabout the route. The distribution is pre-emp-tive and takes into consideration:Rthe sections of the journey aheadRthe energy consumption on thewhole routeThe condition of charge of the high-voltagebattery is thus systematically controlled. Inaddition, the control function takes intoaccount that:Rthe fuel saving through the use of electricalenergy can vary, dependent on the route(e.g. urban, interurban or highway)Rthe use of electrical energy is held availablefor electric driving, particularly for urbanroutes

The vehicle thus automatically selects theoptimum driving mode for the respective sec-tion of the route.Map-based energy management is availableunder the following conditions:Rdrive program E+ is selectedRHYBRID driving mode is selectedRactive route guidance is activatedRsuitable map data is availableWhen map-based energy management isengaged, the area in front of the vehicle in themultifunction display will be green.

Whendoing so, vary the distance between remotecontrolA and the rear-view mirror.The required distance between remotecontrolA and the integrated garage dooropener depends on the garage door drivesystem. Several attempts might be neces-sary. You should test every position for atleast 25 seconds before trying anotherposition.

Synchronizing the rolling codePay attention to the "Important safety notes"(Y page 398).If the garage door system uses a rolling code,you will also have to synchronize the garagedoor system with the integrated garage dooropener in the rear-view mirror. To do this youwill need to use the programming button onthe door drive control panel. The program-ming button may be positioned at differentlocations depending on the manufacturer. Itis usually located on the door drive unit on thegarage ceiling.Familiarize yourself with the garage doordrive operating instructions, e.g. under "Pro-

gramming of additional remote controls",before carrying out the following steps.Your vehicle must be within reach of thegarage door or gate opener drive. Make surethat neither your vehicle nor any persons/objects are present within the sweep of thedoor or gate.X Turn the SmartKey to position 2 in the igni-tion lock (Y page 189).

X Get into the vehicle.X Press previously programmed button;,= or? on the integrated garage dooropener until the door closes.The rolling code synchronization is thencomplete.

Notes on programming the remote con-trolCanadian radio frequency laws require a"break" (or interruption) of the transmissionsignals after broadcasting for a few seconds.Therefore, these signals may not last longenough for the integrated garage dooropener. The signal is not recognized duringprogramming. Comparable with Canadianlaw, some U.S. garage door openers also fea-ture a "break".Proceed as follows:Rif you live in CanadaRif you have difficulties programming thegarage door opener (regardless of whereyou live) when using the programmingsteps

For safety reasons, Mercedes-Benz recom-mends that you only use batteries which havebeen tested and approved for your vehicle byMercedes-Benz. These batteries provideincreased impact protection to prevent vehi-

cle occupants from suffering acid burnsshould the battery be damaged in the event ofan accident.In order for the battery to achieve the maxi-mum possible service life, it must always besufficiently charged.Like other batteries, the vehicle battery maydischarge over time if you do not use thevehicle. In this case, have the battery discon-nected at a qualified specialist workshop. Youcan also charge the battery with a chargerrecommended by Mercedes-Benz. Contact aqualified specialist workshop for further infor-mation.Have the battery condition of charge checkedmore frequently if you use the vehicle mainlyfor short trips or if you leave it standing idlefor a lengthy period. Consult a qualified spe-cialist workshop if you wish to leave yourvehicle parked for a long period of time.

i Remove the SmartKey if you park thevehicle and do not require any electricalconsumers. The vehicle will then use verylittle energy, thus conserving batterypower.

i Hybrid vehicles: if the battery conditionof charge is sufficient, the high-voltage bat-tery can also supply the 12 V battery withenergy. This only happens if the conditionof charge of the 12 V battery requires this,e.g. after using electrical consumers for anextended period with the engine switchedoff. As the on-board voltage is continuouslymonitored this can also be performedwhenthe engine is switched off. The condition ofcharge of the 12 V battery and the on-boardvoltage are thereby kept stable for a longerperiod.

Blown fuses must be replaced with fuses ofthe same rating, which you can recognize bythe color and value. The fuse ratings are listedin the fuse allocation chart.The fuse allocation chart is on the fuse box inthe trunk (Y page 440).If a newly inserted fuse also blows, have thecause traced and rectified at a qualified spe-cialist workshop, e.g. an authorizedMercedes-Benz Center.

! Only use fuses that have been approvedfor Mercedes-Benz vehicles and whichhave the correct fuse rating for the systemconcerned. Otherwise, components or sys-tems could be damaged.

The fuses in your vehicle serve to close downfaulty circuits. If a fuse blows, all the compo-nents on the circuit and their functions stopoperating.

Before changing a fuseX Secure the vehicle against rolling away(Y page 220).

X Switch off all electrical consumers.X Make sure that the ignition is switched off(Y page 189).

When parking your vehicle, make sure thatthe tires do not get deformed by the curb orother obstacles. If it is necessary to drive overcurbs, speed humps or similar elevations, tryto do so slowly and at an obtuse angle. Oth-erwise, the tires, particularly the sidewalls,may be damaged.

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.

Regularly check the wheels and tires of yourvehicle for damage at least once a month, aswell as after driving off-road or on roughroads. Damaged wheels can cause a loss oftire pressure. Pay particular attention to dam-age such as:Rcuts in the tiresRpuncturesRtears in the tiresRbulges on tiresRdeformation or severe corrosion on wheelsRegularly check the tire tread depth and thecondition of the tread across the whole widthof the tire (Y page 443). 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 protectthe valve against dirt and moisture. Do notmount anything onto the valve other than thestandard valve cap or other valve capsapproved by Mercedes-Benz for your vehicle.Do not use any other valve caps or systems,e.g. tire pressure monitoring systems.Regularly check the pressure of all the tiresparticularly prior to long trips. Adjust the tirepressure as necessary (Y page 445).

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.

Bar indicator: for tread wear is integratedinto the tire tread.Treadwear indicators (TWI) are required bylaw. Six indicators are positioned on the tiretread. They are visible once a tread depth ofapproximatelyá in (1.6 mm) has been

Selecting, mounting and replacingtiresROnly mount tires and wheels of the sametype and make.Exception: it is permissible to install a dif-ferent type or make in the event of a flattire. Observe the "MOExtended tires (tireswith run-flat characteristics" section(Y page 423).ROnly mount tires of the correct size ontothe wheels.RBreak in new tires at moderate speeds forthe first 60miles (100 km). They only reachtheir full performance after this distance.RDo not drive with tires which have too littletread depth, as this significantly reducesthe traction on wet roads (hydroplaning).RReplace the tires after six years at the lat-est, regardless of wear.

MOExtended tires (tires with run-flatproperties)With MOExtended tires (tires with run flatcharacteristics), you can continue to driveyour vehicle even if there is a total loss ofpressure in one or more tires.MOExtended tires may only be used in con-junction with an active tire pressure losswarning systemorwith an active tire pressuremonitor and on wheels specifically tested byMercedes-Benz.Notes on driving with MOExtended tires witha flat tire (Y page 423).

i Vehicles equippedwithMOExtended tiresare not equipped with a TIREFIT kit at thefactory. It is therefore recommended thatyou additionally equip your vehicle with aTIREFIT kit if you mount tires that do notfeature run-flat properties, e.g. winter tires.

A TIREFIT kit can be obtained from a quali-fied specialist workshop.

Winter operation

General notesHave your vehicle winterproofed at a qualifiedspecialist workshop at the onset of winter.Observe the notes in the "Changing a wheel"section (Y page 465).

Driving with summer tiresAt temperatures below 45‡ (+7†), summertires lose elasticity and therefore traction andbraking power. Change the tires on your vehi-cle to M+S tires. Using summer tires at verycold temperatures could cause cracks toform, thereby damaging the tires perma-nently. Mercedes-Benz cannot acceptresponsibility for this 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 win-ter tires or all-season tires. Both types of tireare identified by the M+S marking.Only winter tires bearing thei snowflakesymbol in addition to the M+S marking pro-vide the best possible grip in wintry road con-

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.

For safety reasons, Mercedes-Benz recom-mends that you only use snow chains thathave been specially approved for your vehicleby Mercedes-Benz, or are of a correspondingstandard of quality.If you intend to mount snow chains, pleasebear the following points in mind:RSnow chains may not be mounted on allwheel/tire combinations. Permissiblewheel-tire combinations (Y page 471).ROnly use snow chains when driving onroads completely covered by snow.Remove the snow chains as soon as possi-

ble when you come to a road that is notsnow-covered.RLocal regulations may restrict the use ofsnow chains. Observe the appropriate reg-ulations if you wish to mount snow chains.RDo not exceed the maximum permissiblespeed of 30 mph (50 km/h).ROn vehicles with AIRMATIC (Y page 246) orActive Body Control (ABC) (Y page 244),you must drive at raised vehicle level ifsnow chains have been installed.

You may wish to deactivate ESP® (Y page 82)when pulling awaywith snow chains installed.You can thereby allow the wheels to spin in acontrolled manner, achieving an increaseddriving force (cutting action).

Tire and Loading Information placard

: Recommended tire pressuresThe Tire and Loading Information placard ison the B-pillar on the driver's side(Y page 453).The Tire and Loading Information placard con-tains the recommended tire pressures forcold tires. The recommended tire pressuresare valid for the maximum permissible loadand up to the maximum permissible vehiclespeed.

Example: tire pressure table for all tires permittedfor this vehicle by the factory

The tire pressure table contains the recom-mended pressures for cold tires for variousoperating conditions, i.e. differing load andspeed conditions.

Example: tire pressure table with tire dimensions

If a tire size precedes a tire pressure, the tirepressure information following is only validfor that tire size. The load conditions "partiallyladen" and "fully laden" are defined in thetable for different numbers of occupants andamounts of luggage. The actual number ofseats 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 sizeand can be found on the tire sidewall(Y page 459).If the tire pressures have been set to thelower values for lighter loads and/or lowerroad speeds, the pressures should be reset tothe higher values:Rif you want to drive with an increased loadand/orRif you want to drive at higher road speeds

i The tire pressures for increased loadsand/or higher road speeds, shown in thetire pressure table, may have a negativeeffect on driving comfort.

If the tire pressure is not set correctly, thiscan lead to an excessive build up of heat anda sudden loss of pressure.Formore 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 thetire pressure. The outer appearance of a tiredoes not permit any reliable conclusion aboutthe tire pressure. On vehicles equipped withthe electronic tire pressure monitor, the tirepressure can be checked in the on-boardcomputer.The tire temperature and pressure increasewhen the vehicle is in motion. This is depend-ent on 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 withoutdirect sunlight on the tires for at least threehours andRif the vehicle has not been driven furtherthan 1 mile (1.6 km)

The tire temperature changes depending onthe outside temperature, the vehicle speedand the tire load. If the tire temperaturechanges by 18 ‡ (10 †), the tire pressurechanges by approximately 10 kPa (0.1 bar/1.5 psi). Take this into account when check-ing the pressure of warm tires. Only correctthe tire pressure if it is too low for the currentoperating conditions. If you check the tirepressure when the tires are warm, the result-ing value will be higher than if the tires werecold. This is normal. Do not reduce the tirepressure to the value specified for cold tires.The tire pressure would otherwise be 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 inside of thefuel filler flap

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.

Overinflated tires may:Rincrease the braking distanceRadversely affect handlingRwear excessively and/or unevenlyRhave an adverse effect on ride comfortRbe more susceptible to damage

Maximum tire pressures

: Example: maximum permissible tire pres-sure

Never exceed the maximum permissible tireinflation pressure. Always observe the rec-ommended tire pressure for your vehiclewhen adjusting the tire pressure(Y page 445).

i The actual values for tires are vehicle-specific and may deviate from the values inthe illustration.

Checking the tire pressures

X If the tire pressure is too low, increase it tothe recommended value.

X If the tire pressure is too high, release air bypressing down the metal pin in the valve.Use the tip of a pen, for example. Then,check the tire pressure again using the tirepressure gauge.

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

Tire pressure monitor

General notesIf a tire pressuremonitor is installed, the vehi-cle's wheels have sensors that monitor thetire pressures in all four tires. The tire pres-sure monitor warns you if the pressure dropsin one or more of the tires. The tire pressuremonitor only functions if the correspondingsensors are installed in all wheels.Information on tire pressures is displayed inthe multifunction display. After a fewminutesof driving, the current tire pressure of eachtire is shown in the ServiceServicemenu of the mul-tifunction display; see illustration (example).

For information on the message display, referto the "Checking the tire pressure electroni-cally" section (Y page 450).

Important safety notes

G WARNINGEach tire, including the spare (if provided),should be checked at least once every twoweeks when cold and inflated to the pressure

recommended 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 totrigger 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 the

It is the driver's responsibility to set the tirepressure to that recommended for cold tireswhich is suitable for the operating situation(Y page 445). Note that the correct tire pres-sure for the current operating situation mustfirst be taught-in to the tire pressure monitor.If there is a substantial loss of pressure, thewarning threshold for the warning message isaligned to the reference values taught-in.Restart the tire pressuremonitor after adjust-ing the pressure of the cold tires(Y page 451). The current pressures aresaved as new reference values. As a result, awarning message will appear if the tire pres-sure drops significantly.The tire pressure monitor does not warn youof an incorrectly set tire pressure. Observethe notes on the recommended tire pressure(Y page 445).The tire pressure monitor is not able to warnyou of a sudden loss of pressure, e.g. if thetire is penetrated by a foreign object. In theevent of a sudden loss of pressure, bring thevehicle to a halt by braking carefully. Avoidabrupt steering maneuvers.The tire pressure monitor has a yellow warn-ing lamp in the instrument cluster for indicat-ing a pressure loss or malfunction. Whetherthe warning lamp flashes or lights up indi-cates whether a tire pressure is too low or thetire pressure monitor is malfunctioning:Rif the warning lamp is lit continuously, thetire pressure on one or more tires is signif-icantly too low. The tire pressure monitor isnot malfunctioning.Rif the warning lamp flashes for around aminute and then remains lit constantly, thetire pressure monitor is malfunctioning.

i In addition to the warning lamp, a mes-sage appears in the multifunction display.

You can find further information under:(Y page 348).

If the tire pressure monitor is malfunctioning,it may take up to ten minutes for the tirepressure warning lamp to inform you of themalfunction by flashing for approximately oneminute and then remaining lit. When the mal-function 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.The tire pressures shown by the on-boardcomputer refer to those measured at sealevel. At high altitudes, the tire pressure val-ues indicated by a pressure gauge are higherthan those shown by the on-board computer.In this case, do not reduce the tire pressures.The operation of the tire pressuremonitor canbe affected by interference from radio trans-mitting equipment (e.g. radio headphones,two-way radios) that may be being operatedin or near the vehicle.

Important safety notesThe tire pressure warning system does notwarn you of an incorrectly set tire pressure.Observe the notes on the recommended tirepressure (Y page 445).

The tire pressure loss warning does notreplace the need to regularly check the tirepressure. An even loss of pressure on severaltires at the same time cannot be detected bythe tire pressure loss warning system.The tire pressure monitor is not able to warnyou of a sudden loss of pressure, e.g. if thetire is penetrated by a foreign object. In theevent of a sudden loss of pressure, bring thevehicle to a halt by braking carefully. Avoidabrupt steering maneuvers.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 (cor-nering at high speeds or driving with highrates of acceleration).Ryou are driving with a heavy load (in thevehicle or on the roof).

Instruction labels for tires and loads

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 showthe maximum possible load.(1) The Tire and Loading Information placard

is on the B-pillar on the driver's side. TheTire and Loading Information placardshows themaximum permissible numberof occupants and the maximum permis-sible vehicle load. It also contains detailsof the tire sizes and corresponding pres-sures for tires mounted at the factory.

(2) The vehicle identification plate is on theB-pillar on the driver's side. The vehicleidentification plate informs you of thegross vehicle weight rating. It is made upof the vehicle weight, all vehicle occu-pants, the fuel and the cargo. You canalso find information about themaximumgross axle weight rating on the front andrear axle.The maximum gross axle weight rating isthe maximum weight that can be carriedby one axle (front or rear axle). Neverexceed the maximum load or the maxi-mum gross axle weight rating for thefront 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 575pursuant to the "National Traffic and MotorVehicle Safety Act of 1966".X Step 1: Locate the statement "The com-bined weight of occupants and cargoshould never exceed XXX kg or XXX lbs." onyour vehicle’s Tire and Loading Informationplacard.

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

X Step 3: Subtract the combined weight ofthe driver and passengers from XXX kilo-grams or XXX lbs.

Uniform Tire Quality Grading Stand-ards

Overview of Tire Quality Grading Stand-ards

Uniform Tire Quality Grading Standards areU.S. government specifications. Their pur-pose is to provide drivers with uniform relia-ble information on tire performance data. Tiremanufacturers have to grade tires using threeperformance factors:: treadwear grade,;traction grade and= temperature grade.These regulations do not apply to Canada.Nevertheless, all tires sold in North Americaare provided with the corresponding qualitygrading markings on the sidewall of the tire.Quality grades can be found, where applica-ble, on the tire sidewall between the treadshoulder and maximum tire width.Example:RTreadwear grade: 200RTraction grade: AARTemperature grade: AAll passenger car tires must conform to thestatutory safety requirements in addition tothese grades.

i The actual values for tires are vehicle-specific and may deviate from the values inthe illustration.

TreadwearThe treadwear grade is a comparative ratingbased on thewear rate of the tire when testedunder controlled conditions on a specifiedU.S. government course. For example, a tiregraded 150 would wear one and one-halftimes as well on the government course as atire graded 100.The relative performance of tires dependsupon the actual conditions of their use, how-ever, and may depart significantly from thenorm due to variations in driving habits, ser-vice practices and differences in road char-acteristics and climate conditions.

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 damageto the drive train.

The traction grades – from highest to lowest –are AA, A, B and C. Those grades representthe tire's ability to stop on wet pavement asmeasured under controlled conditions onspecified government test surfaces of asphaltand concrete. A tire marked C may have poortraction performance.The safe speed on a wet, snow covered or icyroad is always lower than on dry road surfa-ces.You should pay special attention to road con-ditions when temperatures are around freez-ing point.Mercedes-Benz recommends a minimumtread depth ofã in (4 mm) on all four wintertires. Observe the legally required minimumtire tread depth (Y page 443).Winter tires canreduce the braking distance on snow-coveredsurfaces in comparison with summer tires.The braking distance is still much further than

on surfaces that are not icy or covered withsnow. Take appropriate care when driving.Further information on winter tires (M+Stires) (Y page 444).

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. They represent the tire's resistance tothe generation of heat and its ability to dissi-pate heat when tested under controlled con-ditions on a specified indoor laboratory testwheel. Sustained high temperature can causethe material of the tire to degenerate andreduce tire life, and excessive temperaturecan lead to sudden tire failure. The grade Ccorresponds to a level of performance whichall passenger car tires must meet under theFederal Motor Vehicle Safety Standard No.109. Grades B and A represent higher levelsof performance on the laboratory test wheelthan the minimum required by law.

DOT, Tire Identification Number (TIN)US tire regulations stipulate that every tiremanufacturer or retreader must imprint a TINin or on the sidewall of each tire produced.

The TIN is a unique identification number. TheTIN enables the tiremanufacturers or retread-ers to inform purchasers of recalls and othersafety-relevant matters. It makes it possiblefor the purchaser to easily identify the affec-ted tires.The TIN is made up of manufacturer identifi-cation code;, tire size=, tire type code?and manufacturing dateA.DOT (Department of Transportation): tiresymbol: marks that the tire complies withthe requirements of the U.S. Department ofTransportation.Manufacturer identification code: manu-facturer identification code; providesdetails on the tire manufacturer. New tireshave a code with two symbols. Retreadedtires have a code with four symbols.Tire size: identifier= describes the tire size.Tire type code: tire type code? can be usedby the manufacturer as a code to describespecific characteristics of the tire.

Changing a wheel

Flat tireThe "Breakdown assistance" section(Y page 423) contains information and noteson how to deal with a flat tire. Information ondriving with MOExtended tires in the event ofa flat tire can be found under "MOExtendedtires (tires with run-flat characteristics"(Y page 423).

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 rearwheels only if thewheelsand tires are of the same dimensions.

! On vehicles equipped with a tire pressuremonitor, electronic components are loca-ted in the wheel.Tire-mounting tools should not be usednear the valve. This could damage the elec-tronic components.Only have tires changed at a qualified spe-cialist workshop.

Always observe the instructions and safetynotes in the "Mounting a wheel" section(Y page 466).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 tiresin the center.If your vehicle's tire configuration allows, youcan rotate the wheels according to the inter-vals in the tire manufacturer's warranty bookin your vehicle documents. If no warrantybook is available, the tires should be rotatedevery 3,000 to 6,000 miles (5,000 to10,000 km), or earlier if tire wear requires.Ensure the direction of rotation ismaintained.Clean the contact surfaces of the wheel andthe brake disc thoroughly every time a wheelis rotated. Check the tire pressure and, if nec-essary, restart the tire pressure loss warningsystem (Y page 452) or the tire pressuremonitor (Y page 451).

Direction of rotationTires with a specified direction of rotationhave additional benefits, e.g. if there is a riskof hydroplaning. These advantages can onlybe gained if the tires are installed correspond-ing to the direction of rotation.An arrow on the sidewall of the tire indicatesits correct direction of rotation.

Storing wheelsStorewheels that are not being used in a cool,dry and preferably dark place. Protect thetires from oil, grease, gasoline and diesel.

RGasoline with metalliferous additivesRDieselDo not mix such fuels with the fuel recom-mended for your vehicle. Do not use addi-tives. Otherwise, engine damage mayoccur. This does not include cleaning addi-tives for the removal and prevention of res-idue build-up. Gasoline may only be mixedwith cleaning additives recommended byMercedes-Benz; see "Additives". You canobtain further information from any author-ized Mercedes-Benz Center.

! To ensure the longevity and full perform-ance of the engine, only premium-gradeunleaded gasoline must be used.If standard unleaded gasoline is unavaila-ble and you have to refuel with unleadedgasoline of a lower grade, observe the fol-lowing precautions:ROnly fill the fuel tank to half full with reg-ular unleaded gasoline and fill the restwith premium-grade unleaded gasolineas soon as possible.RDo not drive at the maximum speed.RAvoid sudden acceleration and enginespeeds over 3,000 rpm.

Youwill usually find information about the fuelgrade on the pump. If you cannot find thelabel on the pump, ask the staff for assis-tance.

i For further information, consult a quali-fied specialist workshop or visithttp://www.mbusa.com (USA only).

i E10 fuel contains up to 10% bioethanol.Your vehicle is E10-compatible. You canrefuel your vehicle using E10 fuel.

As a temporarymeasure, if the recommendedfuel is not available, you may also use regularunleaded gasoline with an octane rating of87 AKI/91 RON. This may reduce engine per-formance and increase fuel consumption.Avoid driving at full throttle and sudden accel-eration. Never refuel using fuel with a lowerAKI.

Information on refueling (Y page 206).

Additives! Operating the engine with fuel additivesadded later can lead to engine failure. Donot mix fuel additives with fuel. This doesnot include additives for the removal andprevention of residue buildup. gasolinemust only be mixed with additives recom-mended by Mercedes-Benz. Comply withthe instructions for use on the productlabel. More information about recommen-ded additives can be obtained from anyauthorized Mercedes-Benz Center.

Mercedes-Benz recommends that you usebranded fuels that have additives.The quality of the fuel available in some coun-tries may not be sufficient. Residue couldbuild up in the injection system as a result. Insuch cases, and in consultation with anauthorized Mercedes-Benz Center, the gaso-line may be mixed with the cleaning additiverecommended by Mercedes-Benz. You mustobserve the notes and mixing ratios specifiedon the container.

Engine oil

General notes

! Never use engine oil or an oil filter of aspecification other than is necessary to ful-fill the prescribed service intervals. Do notchange the engine oil or oil filter in order toachieve longer replacement intervals thanthose prescribed. You could otherwisecause engine damage or damage to theexhaust gas aftertreatment.Follow the instructions in the service inter-val display regarding the oil change. Other-wise, you may damage the engine and theexhaust gas aftertreatment.

When handling engine oil, observe the impor-tant safety notes on service products(Y page 489).

Additives

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

Engine oil viscosity

Viscosity describes the flow characteristicsof a fluid. If an engine oil has a high viscosity,this means that it is thick; a low viscositymeans that it is thin.Select an engine oil with an SAE classification(viscosity) suitable for the prevailing outsidetemperatures. The table shows you whichSAE classifications are to be used. The low-temperature characteristics of engine oilscan deteriorate significantly, e.g. as a resultof aging, soot and fuel deposits. It is thereforestrongly recommended that you carry out reg-ular oil changes using an approved engine oilwith the appropriate SAE classification.

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 brakefluid 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.

Coolant

Important safety notes

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 befound in the Mercedes-Benz Specificationsfor Service Products, MB BeVo 310.1, e.g.on the Internet athttp://bevo.mercedes-benz.com. Or con-tact a qualified specialist workshop.

! Always use a suitable coolant mixture,even in countries where high temperaturesprevail.Otherwise, the engine cooling system is notsufficiently protected from corrosion andoverheating.

i Have the coolant regularly replaced at aqualified specialist workshop and thereplacement confirmed in theMaintenanceBooklet.

The coolant is a mixture of water and anti-freeze/corrosion inhibitor. It performs thefollowing tasks:Rcorrosion protectionRantifreeze protectionRraising the boiling pointIf the coolant has antifreeze protection downto -35‡ (-37†), the boiling point of the cool-ant during operation is approximately 266 ‡(130 †).The antifreeze/corrosion inhibitor concentra-tion in the engine cooling system should:Rbe at least 50%. This will protect the enginecooling system against freezing down toapproximately -35 ‡ (-37 †).Rnot exceed 55% (antifreeze protectiondown to -49 ‡ [-45 †]). Otherwise, heatwill not be dissipated as effectively.

Mercedes-Benz recommends an antifreeze/corrosion inhibitor concentrate in accord-ance withMB Specifications for Service Products 310.1.

i When the vehicle is first delivered, it is fil-led with a coolant mixture that ensuresadequate antifreeze and corrosion protec-tion.

i The coolant is checked with every main-tenance interval at a qualified specialistworkshop.
