Occupant safety

Overview of occupant safetyIn this section, you will learn the mostimportant facts about the restraint systemcomponents of the vehicle.The restraint system consists of:Rseat beltsRchild restraint systemsRLATCH-type (ISOFIX) child seat anchorsAdditional protection is provided by:RSRS (Supplemental Restraint System)RNECK-PRO head restraintsRAir bag system components with:

- PASSENGER AIR BAG OFF indicator lamp- front-passenger seat with Occupant

Classification System (OCS)The different air bag systems workindependently of each other. The protectivefunctions of the system work in conjunctionwith each other. Not all air bags are deployedin an accident.

G WARNINGModifications to or work improperlyconducted on restraint system componentsor their wiring, as well as tampering withinterconnected electronic systems, can lead

to the restraint systems no longer functioningas intended.Air bags or Emergency Tensioning Devices(ETDs), for example, could deployinadvertently or fail to deploy in accidentsalthough the deceleration threshold for airbag deployment is exceeded. Therefore,never modify the restraint systems. Do nottamper with electronic components or theirsoftware.

i See "Children in the vehicle"(Y page 52) for more information oninfants and children traveling with you inthe vehicle and restraints for infants andchildren.

SRS (Supplemental Restraint System)

IntroductionSRS consists of:Rthe 6 SRS warning lampRair bagsRair bag control unit (with crash sensors)REmergency Tensioning DevicesRbelt force limitersSRS reduces the risk of occupants cominginto contact with the vehicle's interior in theevent of an accident. It can also reduce theeffect of the forces to which occupants aresubjected during an accident.

SRS warning lampSRS functions are checked regularly whenyou switch on the ignition and when theengine is running. Therefore, malfunctionscan be detected in good time.The 6 SRS warning lamp in the instrumentcluster lights up when the ignition is switchedon. It goes out no later than a few secondsafter the engine is started.The SRS components are in operationalreadiness when the 6 SRS warning lampis not lit while the engine is running .

G WARNINGThe SRS self-check has detected amalfunction if the 6 SRS warning lamp:Rdoes not come on at allRfails to go out approximately 4 seconds

after the engine was startedRcomes on after the engine was started or

while drivingFor your safety, Mercedes-Benz stronglyrecommends that you have the systemchecked as soon as possible at an authorizedMercedes-Benz Center. Otherwise the SRSmay not be activated when it is needed in anaccident, which could result in serious or fatalinjury. The SRS might also deployunexpectedly and unnecessarily which couldalso result in injury.In addition, improper work on the SRS createsa risk of rendering the SRS inoperative orcausing unintended air bag deployment. Workon the SRS must therefore only be performedby qualified technicians. Contact anauthorized Mercedes-Benz Center.If it is necessary to modify an air bag systemto accommodate a person with disabilities,contact an authorized Mercedes-Benz Centerfor details.

Safety guidelines for seat belts,Emergency Tensioning Devices (ETDs)and air bags

G WARNINGRDamaged seat belts or seat belts that have

been subjected to stress in an accidentmust be replaced. Their anchoring pointsmust also be checked. Only use seat beltsinstalled or supplied by an authorizedMercedes-Benz Center.RAir bags and pyrotechnic Emergency

Tensioning Devices (ETDs) containperchlorate material, which may requirespecial handling and regard for the

environment. Check your national disposalguidelines. California residents, seewww.dtsc.ca.gov/HazardousWaste/Perchlorate/index.cfm.RAir bags and ETDs are designed to function

on a one-time-only basis. An air bag or ETDthat has deployed must be replaced.RDo not pass seat belts over sharp edges.

They could tear.RDo not make any modification that could

change the effectiveness of the seat belts.RDo not bleach or dye seat belts as this may

severely weaken them. In a crash they maynot be able to provide adequate protection.RNo modifications of any kind may be made

to any components or wiring of the SRS.RDo not change or remove any component

or part of the SRS.RDo not install additional trim material, seat

covers, badges, etc. over the steeringwheel hub, front-passenger front air bagcover, outer sides of the seat backrests,door trim panels, or door frame trims.RDo not install additional electrical/

electronic equipment on or near SRScomponents and wiring.RKeep area between air bags and occupants

free of objects (e.g. packages, purses,umbrellas, etc.).RDo not hang items such as coat hangers

from the coat hooks or handles over thedoor. These items may be thrown around inthe vehicle and cause head and otherinjuries when the window curtain air bag isdeployed.RAir bag system components will be hot after

an air bag has inflated. Do not touch them.RNever place your feet on the instrument

panel, dashboard, or on the seat. Alwayskeep both feet on the floor in front of theseat.RImproper repair work on the SRS creates a

risk of rendering the SRS inoperative orcausing unintended air bag deployment.Work on the SRS must therefore only be

performed by qualified technicians.Contact an authorized Mercedes-BenzCenter.RFor your protection and the protection of

others, when scrapping the air bag unit orETD, our safety instructions must befollowed. These instructions are availablefrom any authorized Mercedes-BenzCenter.RGiven the considerable deployment speed,

required inflation volume, and the materialof the air bags, there is the possibility ofabrasions or other, potentially more seriousinjuries resulting from air bag deployment.

If you sell your vehicle, Mercedes-Benzstrongly recommends that you inform thesubsequent owner that the vehicle isequipped with SRS. Also, refer them to theapplicable section in the Operator's Manual.

Air bags

Important safety notes

G WARNINGAir bags are designed to reduce the incidenceof injuries and fatalities in certain situations:Rfrontal impacts (driver's and front-

passenger front air bags and driver's kneebag)Rside impacts (side impact air bags, window

curtain air bags and pelvis air bags)However, no system available today cancompletely eliminate injuries and fatalities.When the air bags are deployed, a smallamount of powder is released. The powdergenerally does not constitute a health hazardand does not indicate that there is a fire in thevehicle. In order to prevent potentialbreathing difficulties, you should leave thevehicle as soon as it is safe to do so. If youhave any breathing difficulty but cannot getout of the vehicle after the air bag inflates,then get fresh air by opening a window ordoor.

G WARNINGTo reduce the risk of injuries during front airbag inflation, the driver and front-passengermust always be seated correctly and havetheir seat belts fastened accordingly.For maximum protection in the event of acollision, you must always be in the normalseat position with your back against thebackrest. Fasten your seat belt and make surethat it is correctly positioned on your body.Since the air bag inflates with considerablespeed and force, a proper seating positionand correct positioning of the hands on thesteering wheel will help to keep you at a safedistance from the air bag. Occupants who arenot wearing their seat belt, are not seatedproperly or are too close to the air bag can beseriously injured or killed by an air bag as itinflates with great force instantaneously:RSit with the seat belt properly fastened in a

position that is as upright as possible withyour back against the seat backrest.RMove the driver's seat as far back as

possible, still permitting proper operationof vehicle controls. The distance from thecenter of the driver's chest to the center ofthe air bag cover on the steering wheelmust be at least 10 inches(25 cm) or more.You should be able to accomplish this byadjusting the seat and steering wheel. Ifyou have any difficulties, please contact anauthorized Mercedes-Benz Center.RDo not lean your head or chest close to the

steering wheel or dashboard.ROnly hold the steering wheel by the rim.

Placing hands and arms inside the rim canincrease the risk and potential severity ofhand/arm injury when the driver front airbag inflates.RAdjust the front-passenger seat as far back

as possible from the dashboard when theseat is occupied.ROccupants, especially children, should

never place their bodies or lean their headsin the area of the door or the rear side trimpanel where the side impact air bag


fety

inflates. This could result in serious injuriesor death should the side impact air bag bedeployed. Always sit as upright as possible,wear the seat belt properly and use anappropriately sized child restraint, infantrestraint or booster seat recommended forthe size and weight of the child.

Failure to follow these instructions can resultin severe injuries to you or other occupants.If you sell your vehicle, it is important that youmake the buyer aware of this safetyinformation. Be sure to give the buyer thisOperator's Manual.

G WARNINGAccident research shows that the safest placefor children in an automobile is in a rear seat.A side impact air bag related injury may occurif occupants, especially children, are notproperly seated or restrained when next to aside impact air bag which needs to deployrapidly in a side impact in order to do its job.To help avoid the possibility of injury, pleasefollow these guidelines:

(1) Always sit as upright as possibleand use the seat belts properly.Make sure that children 12 yearsold and under use an appropriatelysized child restraint, infantrestraint, or booster seatrecommended for the size andweight of the child.

(2) Always wear seat belts properly.

The air bags are only deployed if the air bagcontrol unit detects the need for deployment.Only in the event of such a situation will theyprovide their supplemental protection.The driver and passenger should always weartheir seat belts. Otherwise, it is not possiblefor the air bags to provide their supplementalprotection.In the event of other types of impacts andimpacts below air bag deploymentthresholds, the air bags will not deploy. Thedriver and passengers will then be protected

to the extent possible by a properly fastenedseat belt. A properly fastened seat belt is alsoneeded to provide the best possibleprotection in a rollover.Air bags provide additional protection; theyare not, however, a substitute for seat belts.All vehicle occupants must fasten their seatbelts regardless of whether your vehicle isequipped with air bags or not.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.

Front air bagsThe front air bags increase protection for thedriver's and front-passenger's head andchest.

Driver's air bag : deploys in front of thesteering wheel; front-passenger front airbag ; deploys in front of and above the glovebox.They are deployed:Rin the event of certain frontal impactsRif the system determines that air bag

Your vehicle has adaptive, two-stage front airbags. In the event of a collision, the air bagcontrol unit evaluates the vehicledeceleration. In the first deployment stage,the front air bag is filled with enoughpropellant gas to reduce the risk of injuries.The front air bag is fully deployed if a seconddeployment threshold is exceeded within afew milliseconds.The deployment of the front-passenger frontair bag is also influenced by the weightcategory of the front passenger, which isdetermined by the Occupant ClassificationSystem (OCS) (Y page 42).The lighter the passenger side occupant, thehigher the vehicle deceleration rate required(predicted at the start of the impact) forsecond stage inflation of the front-passengerfront air bag. In the second stage, the frontair bags are inflated with the maximumamount of propellant gas available.The front air bags are not deployed insituations where a low impact severity ispredicted. You will then be protected by thefastened seat belt.The front-passenger front air bag will onlydeploy if:Rthe system, based on the OCS weight

sensor readings, detects that the front-passenger seat is occupied.Rthe 45 indicator lamp in the center

console is not lit, (Y page 42).Rthe air bag control unit predicts a high

impact severity.

Driver's knee bag

Driver's knee bag : provides additionalprotection for the driver against:Rknee injuriesRthigh injuriesRlower leg injuriesDriver's knee bag : deploys below thesteering wheel. During a frontal impact, if thesystem determines that air bag deploymentcan offer additional protection to thatprovided by the seat belt, driver's kneebag : is deployed along with the driver's airbag. The driver's knee bag : operates bestin conjunction with a properly positioned andfastened seat belt.

Side impact air bags

G WARNINGThe pressure sensors for side impact air bagcontrol are located in the doors. Do notmodify any components of the doors or doortrim panels including, for example, theaddition of door speakers.Improper repair work on the doors or themodification or addition of components to thedoors create a risk of rendering the sideimpact air bags inoperative or causingunintended air bag deployment. Work on thedoors must therefore only be performed byqualified technicians. Contact an authorizedMercedes-Benz Center.


fety

G WARNINGOnly use seat covers which have been testedand approved by Mercedes-Benz for yourvehicle model. Using seat covers or other seatcoverings can cause a malfunction of the sideimpact air bags and/or the pelvis air bags.Contact an authorized Mercedes-Benz Centerfor availability.

When deployed, the side impact air bags offeradditional protection for the thorax of thevehicle occupants on the side of the vehicleon which the impact occurs. However, theydo not protect the:RheadRneckRarms

Front side impact air bags : and rear sideimpact air bags ; deploy next to the outerseat cushions.The side impact air bags are deployed:Ron the side on which an impact occursRat the start of an accident with a high rate

You will then beprotected by the fastened seat belt.

If the OCS detects that the front-passengerseat is not occupied and the front-passengerseat belt is not fastened (the belt tongue isnot engaged in the seat belt buckle), the sideimpact air bag on the front-passenger sidewill not deploy. The side impact air bag on thefront-passenger side will deploy if the front-passenger seat belt is fastened, regardless ofwhether the front-passenger seat is occupiedor not.

Pelvis air bags

G WARNINGOnly use seat covers which have been testedand approved by Mercedes-Benz for yourvehicle model. Using seat covers or other seatcoverings can cause a malfunction of the sideimpact air bags and/or the pelvis air bags.Contact an authorized Mercedes-Benz Centerfor availability.

Pelvis air bag deployment enhances the levelof protection of the vehicle occupants on theside of the vehicle on which the impactoccurs.

Window curtain air bags : will not deploy inimpacts with deceleration rates which do notexceed the system's preset deploymentthresholds for vehicle deceleration oracceleration. You will then be protected bythe fastened seat belt.

Occupant Classification System(OCS)

How the occupant classificationsystem worksThe Occupant Classification System (OCS)categorizes the occupant on the front-passenger seat by means of a weight sensor.The front-passenger front air bag isdeactivated automatically for certain weightcategories. The 45 indicator lampshows you the current status. If the45 indicator lamp is illuminated, thefront-passenger front air bag is deactivated.The system does not deactivate:Rthe side impact air bagRthe pelvis air bagRthe window curtain air bagRthe Emergency Tensioning DevicesTo be classified correctly, the front passengermust sit:Rwith the seat belt fastened correctlyRin a position that is as upright as possible

with their back against the seat backrestRwith their feet on the floorIf the front-passenger's weight is transferredto another object in the vehicle (e.g. byleaning on armrests), OCS may not be able toapproximate the occupant's weight category.If the front-passenger seat, the seat cover orthe seat cushion are damaged, have thenecessary repair work carried out at anauthorized Mercedes-Benz Center.For safety reasons, Mercedes-Benzrecommends that you only use seataccessories which have been approved byMercedes-Benz.

Both the driver and the passenger shouldalways use the 45 indicator lamp asan indication of whether or not the passengeris properly positioned.

G WARNINGIf the 45 indicator lamp illuminateswhen an adult or someone larger than a smallindividual is in the front passenger seat, havethe front passenger reposition himself orherself in the seat until the 45indicator lamp goes out.In the event of a collision, the air bag controlunit will not allow front passenger front air bagdeployment when the OCS has classified thefront passenger seat occupant as weighing asmuch as or less than a typical 12-month-oldchild in a standard child restraint or if the frontpassenger seat is classified as being empty.When the OCS senses that the frontpassenger seat occupant is classified asbeing up to or less than the weight of a typical12-month-old child in a standard childrestraint, the 45 indicator lamp willilluminate when the engine is started andremain illuminated. This indicates that thefront passenger front air bag is deactivated.When the OCS senses that the frontpassenger seat is classified as being empty,the 45 indicator lamp will illuminatewhen the engine is started and remainilluminated. This indicates that the frontpassenger front air bag is deactivated.When the OCS senses that the frontpassenger seat occupant is classified asbeing heavier than the weight of a typical 12-month-old child seated in a standard childrestraint or as being a small individual (suchas a young teenager or a small adult), the45 indicator lamp will illuminate forapproximately 6 seconds when the engine isstarted. Depending on occupant weightsensor readings from the seat, it will thenremain illuminated or go out. With the45 indicator lamp illuminated, thefront passenger front air bag is deactivated.

With the 45 indicator lamp out, thefront passenger front air bag is activated.When the OCS senses that the frontpassenger seat occupant is classified as anadult or someone larger than a smallindividual, the 45 indicator lamp willilluminate for approximately six secondswhen the engine is started and then go out.This indicates that the front passenger frontair bag is activated.If the 45 indicator lamp is illuminated,the front passenger front air bag isdeactivated and will not be deployed.If the 45 indicator lamp is notilluminated, the front passenger front air bagis activated and will be deployedRin the event of certain frontal impactsRif the impact exceeds a predetermined

For further information, see "Air bag displaymessages" (Y page 209).

G WARNINGAccording to accident statistics, children aresafer when properly restrained on the rearseats than on the front-passenger seat. Thus,we strongly recommend that children beplaced in the rear seats whenever possible.Regardless of seating position, children 12years old and under must be seated andproperly secured in an appropriate infantrestraint, toddler restraint, or booster seatrecommended for the size and weight of thechild.

The infant or child restraint must be properlysecured with the vehicle's seat belt, the seatbelt and Top Tether strap, or lower anchorsand Top Tether strap, fully in accordance withthe child seat manufacturer's instructions.Occupants, especially children, should alwayssit as upright as possible, wear the seat beltproperly and use an appropriately sized infantrestraint, toddler restraint, or booster seatrecommended for the size and weight of thechild.Children can be killed or seriously injured byan inflating air bag. Note the followingimportant information when circumstancesrequire you to place a child in the front-passenger seat:RYour vehicle is equipped with air bag

technology designed to deactivate thefront-passenger front air bag in your vehiclewhen the system senses the weight of atypical 12-month-old child or less alongwith the weight of a standard appropriatechild restraint on the front-passenger seat.RA child in a rear-facing child restraint on the

front-passenger seat will be seriouslyinjured or even killed if the front-passengerfront air bag inflates in a collision whichcould occur under some circumstances,even with the air bag technology installedin your vehicle. The only means to eliminatethis risk completely is never to place a childin a rear-facing child restraint in the front-passenger seat. We therefore stronglyrecommend that you always place a childin a rear-facing child restraint on the rearseat.RIf you install a rear-facing child restraint on

the front-passenger seat, make sure the45 indicator lamp is illuminated,indicating that the front-passenger front airbag is deactivated. Should the 45indicator lamp not illuminate or go out whilethe restraint is installed, please checkinstallation. Periodically check the45 indicator lamp while driving tomake sure that the 45 indicator

lamp is illuminated. If the 45indicator lamp goes out or remains out, donot transport a child on the front-passengerseat until the system has been repaired.A child in a rear-facing child restraint on thefront-passenger seat will be seriouslyinjured or even killed if the front-passengerfront air bag inflates.RIf you place a child in a forward-facing child

restraint on the front-passenger seat:- move the seat as far back as possible- use the proper child restraint

recommended for the age, size andweight of the child

- secure child restraint with the vehicle'sseat belt according to the child seatmanufacturer's instructions

RFor children larger than the typical 12-month-old child, the front-passenger frontair bag may or may not be activated.

If the driver's air bag deploys, this does notmean that the front-passenger front air bagalso has to deploy.The OCS may have detected that the seat:Rwas empty or occupied by a person with a

weight of up to or less than that of a typical12-month-old child seated in a standardchild restraintRwas occupied by a small individual, such as

a young teenager or a small adultRwas occupied by a child in a child restraint

system, whose weight is greater than thatof a typical 12-month-old child.

These are examples of when the OCSdeactivates the front-passenger front air bag.Deactivation takes place although thecollision fulfills the criteria for deploying thedriver's air bag.

NECK-PRO head restraintsThe NECK-PRO head restraints increaseprotection to the driver's and frontpassenger's head and neck. To this end, theNECK-PRO head restraints on the driver's andfront-passenger seats are moved forwardsand upwards in the event of a rear-endcollision of a certain severity. This providesbetter head support.

G WARNINGDo not secure any objects (e.g. coat hangers)on the NECK-PRO head restraints. Otherwise,the NECK-PRO head restraints may notfunction properly, or in the event of a rear-endcollision may not be able offer the level ofprotection they are designed to provide.

G WARNINGSeat or head restraint covers can cause amalfunction when the NECK-PRO headrestraints are activated or when the sideimpact air bags or pelvis air bags aredeployed, or they can prevent this completely.The NECK-PRO head restraints or side impactair bags/pelvis air bags can therefore notprovide the intended protection. Do not useany seat or head restraint covers.

If the NECK-PRO head restraints have beentriggered in an accident, reset the NECK-PROhead restraints on the driver’s and front-passenger seat (Y page 47). Otherwise, theadditional protection will not be available inthe event of another rear-end collision. Youcan recognize when NECK-PRO headrestraints have been triggered by the fact thatthey have moved forwards and can no longerbe adjusted.

G WARNINGFor your protection, drive only with properlypositioned head restraints.Adjust the head restraint so that it is as closeto the head as possible and the center of thehead restraint supports the back of the headat eye level. This will reduce the potential for

injury to the head and neck in the event of anaccident or similar situation.

Resetting triggered NECK-PRO headrestraints

G WARNINGFor safety reasons, have the NECK-PRO headrestraints checked at an authorizedMercedes-Benz Center after a rear-endcollision.

G WARNINGWhen pushing back the NECK-PRO headrestraint cushion, make sure your fingers donot become caught between the headrestraint cushion and the cover. Failure toobserve this could result in injuries.

i Resetting the NECK-PRO head restraintsrequires a lot of strength. If you havedifficulty resetting the NECK-PRO headrestraints, have this work carried out at aqualified specialist workshop, e.g. anauthorized Mercedes-Benz Center.

G WARNINGAlways fasten your seat belt before driving off.Always make sure all of your passengers areproperly restrained. You and your passengersshould always wear seat belts.Failure to wear and properly fasten andposition your seat belt greatly increases yourrisk of injuries and their likely severity in anaccident.If you are ever in an accident, your injuries canbe considerably more severe without yourseat belt properly buckled. Without your seatbelt buckled, you are much more likely to hitthe interior of the vehicle or be ejected fromit. You can be seriously injured or killed.In the same crash, the possibility of injury ordeath is lessened if you are properly wearingyour seat belt. The air bags can only protectas intended if the occupants are properlywearing their seat belts.

G WARNINGNever ride in a moving vehicle with the seatbackrest in an excessively reclined position as

this can be dangerous. You could slide underthe seat belt in a collision. If you slide underit, the seat belt would apply force at theabdomen or neck. That could cause seriousor even fatal injuries. The seat backrest andseat belt provide the best restraint when thewearer is in a position that is as upright aspossible and the seat belt is properlypositioned on the body.

G WARNINGNever let more people ride in the vehicle thanthere are seat belts available. Make sureeveryone riding in the vehicle is correctlyrestrained with a separate seat belt. Neveruse a seat belt for more than one person at atime.

G WARNINGDamaged seat belts or seat belts that havebeen subjected to stress in an accident mustbe replaced and their anchoring points mustalso be checked.Only use seat belts which have been approvedby Mercedes-Benz.Do not make any modifications to the seatbelts. This can lead to unintended activationof the ETDs or to their failure to activate whennecessary.Do not bleach or dye seat belts as this mayseverely weaken them. In a crash they maynot be able to provide adequate protection.Have all work carried out only by qualifiedtechnicians. Contact an authorizedMercedes-Benz Center.

Correct use of the seat belts

G WARNINGUSE SEAT BELTS PROPERLYRSeat belts can only work when used

properly. Never wear seat belts in any otherway than as described in this section, as


fety

that could result in serious injuries in theevent of an accident.REach occupant should wear their seat belt

at all times, because seat belts help reducethe likelihood of and potential severity ofinjuries in accidents, including rollovers.The integrated restraint system includesSRS (driver front air bag, driver's side kneebag, front-passenger front air bag, sideimpact air bags, pelvis air bags, windowcurtain air bags for the side windows),Emergency Tensioning Devices, seat beltforce limiters, and front seat knee bolsters.The system is designed to enhance theprotection offered to properly beltedoccupants in certain frontal (front air bags,driver's side knee bag, and ETDs) and side(side impact air bags, pelvis air bags,window curtain air bags, and ETDs) impactswhich exceed preset deploymentthresholds.RNever wear the shoulder belt under your

arm, across your neck or off your shoulder.In a frontal crash, your body would movetoo far forward. That would increase thechance of head and neck injuries. The seatbelt would also apply too much force to theribs or abdomen, which could severelyinjure internal organs such as your liver orspleen.Adjust the seat belt so that the shouldersection is located as close as possible tothe middle of the shoulder. It should nottouch the neck. Never pass the shoulderportion of the seat belt under your arm.RPosition the lap belt as low as possible on

your hips and not across the abdomen. Ifthe lap belt is positioned across yourabdomen, it could cause serious injuries ina crash.RNever wear seat belts over rigid or

breakable objects in or on your clothing,such as eyeglasses, pens, keys etc., asthese might cause injuries.

RMake sure the seat belt is always fittedsnugly. Take special care of this whenwearing loose clothing.RNever use a seat belt for more than one

person at a time. Do not fasten a seat beltaround a person and another person orother objects at the same time.RSeat belts should not be worn twisted. In a

crash, you would not have the full width ofthe seat belt to distribute impact forces.The twisted seat belt against your bodycould cause injuries.RPregnant women should also always use a

lap-shoulder belt. The lap belt portionshould be positioned as low as possible onthe hips to avoid any possible pressure onthe abdomen.RPlace the seat backrest in a position that is

as upright as possible.RCheck your seat belt during travel to make

sure it is properly positioned.RNever place your feet on the instrument

panel, dashboard, or on the seat. Alwayskeep both feet on the floor in front of theseat.RWhen using a seat belt to secure infant

restraints, toddler restraints, or children inbooster seats, always follow the child seatmanufacturer's instructions.

G WARNINGDo not pass seat belts over sharp edges. Theycould tear.Do not allow the seat belt to get caught in thedoor or in the seat adjustment mechanism.This could damage the seat belt.Never attempt to make modifications to seatbelts. This could impair the effectiveness ofthe seat belts.

Belt warning for the driver and frontpassengerRegardless of whether the driver and frontpassenger have fastened their seat beltsalready, the 7 seat belt warning lamplights up for 6 seconds after every enginestart. It then goes out if the driver and thefront passenger have fastened their seatbelts.If the driver's seat belt is not fastened afterthe engine is started, an additional warningtone will sound. The warning tone goes outafter approximately six seconds or once thedriver's seat belt is fastened.


fety

If the driver or front passenger have notfastened their seat belt after 6 seconds andthe doors are closed, the 7 seat beltwarning lamp lights up.Runtil the driver or the front passenger have

fastened their seat beltsRif a vehicle speed of 15 mph (25 km/h) is

exceeded once, a warning tone withincreasing intensity sounds additionally fora maximum of 60 seconds or until the driveror front passenger have fastened their seatbelts.

If the driver or front passenger undo their seatbelts during the journey, the 7 seat beltwarning lamp lights up and the warning tonesounds again.The warning tone ceases even if the driver orfront passenger have still not fastened theirseat belt after 60 seconds. The 7 seat beltwarning lamp stops flashing but continues tobe lit.Once the vehicle is stationary, the warningtone is reactivated and the 7 seat beltwarning lamp starts to flash again if thevehicle speed exceeds 15 mph (25 km/h)once.The 7 seat belt warning lamp only goesout if:Rboth the driver and the front passenger

have fastened their seat belts.orRthe vehicle is stationary and a door is open.

i For more information on the 7 seatbelt warning lamp, see "Warning andindicator lamps in the instrument cluster,seat belt" (Y page 227).

Emergency Tensioning Devices, beltforce limitersThe seat belts are equipped with ETDs andseat belt force limiters.The ETDs tighten the seat belts in an accident,pulling them close against the body.

The ETDs do not correct incorrect seatpositions or incorrectly fastened seat belts.The ETDs do not pull vehicle occupants backtowards the backrest.Seat belt force limiters, when triggered, helpto reduce the peak force exerted by the seatbelt on the vehicle occupant.The seat belt force limiters for the front seatsare synchronized with the front air bags.These take on a part of the deceleration force.Thus, the force exerted on the occupant isdistributed over a greater area.The ETDs can only be activated when:Rthe ignition is switched on.Rthe restraint systems are operational; see

"SRS warning lamp" (Y page 36).Rthe belt tongue is engaged in the buckle on

each of the lap-shoulder belts in the front.Rthe front-passenger seat is occupied and

the belt tongue is engaged in the buckle onthe front-passenger side.

The ETDs on the seats in the rearcompartment are triggered independently ofthe lock status of the seat belts.The ETDs are triggered depending on the typeand severity of an accident:Rif, in the event of a head-on or rear-end

collision, the vehicle decelerates oraccelerates rapidly in a longitudinaldirection during the initial stages of theimpactRif, in the event of a side impact, on the side

opposite the impact the vehicledecelerates or accelerates rapidly in alateral direction

If the Emergency Tensioning Devices (ETDs)are triggered, you will hear a bang, and a smallamount of smoke may also be released. Onlyin rare cases will the bang affect your hearing.The smoke that is released generally does notconstitute a health hazard. The 6 SRSwarning lamp lights up.

Child restraint systems

Important safety notesWe recommend that all infants and childrenbe properly secured in an infant or childrestraint system at all times while the vehicleis in motion.The use of seat belts and infant and childrestraint systems is required by law in all 50states, the District of Columbia, the U.S.territories and all Canadian provinces.Infants and children must always be seated inan appropriate infant or child restraint systemrecommended for the size and weight of thechild. The infant or child restraint systemmust be properly secured in accordance withthe manufacturer's instructions. All infant orchild restraint systems must meet U.S.Federal Motor Vehicle Safety Standards 213and 225 and Canadian Motor Vehicle SafetyStandards 213 and 210.2.An information label on the child restraintsystem indicates whether it meets thesestandards. This information is also providedin the installation instructions supplied withthe child restraint system.Always read and follow the manufacturer'sinstructions when using an infant or childrestraint system or booster seat.

Observe all warning signs in the vehicleinterior and on the infant or child restraint.

G WARNINGAccording to accident statistics, children aresafer when properly restrained in the rearseating positions than in the front seatingposition. Thus, we strongly recommend thatchildren be placed in the rear seats wheneverpossible. Regardless of seating position,children 12 years old and under must beseated and properly secured in an appropriateinfant restraint, toddler restraint, or boosterseat recommended for the size and weight ofthe child.The infant or child restraint must be properlysecured with the vehicle's seat belt, the seatbelt and top tether strap, or lower anchors andtop tether strap, fully in accordance with thechild seat manufacturer's instructions.Occupants, especially children, should alwayssit as upright as possible, wear the seat beltproperly and use an appropriately sized infantrestraint, toddler restraint, or booster seatrecommended for the size and weight of thechild.Children can be killed or seriously injured byan inflating air bag. Note the followingimportant information when circumstancesrequire you to place a child in the frontpassenger seat:RYour vehicle is equipped with air bag

technology designed to deactivate the frontpassenger front air bag in your vehiclewhen the system senses the weight of atypical 12-month-old child or less alongwith the weight of a standard appropriatechild restraint on the front passenger seat.RFor children larger than the typical

injured or even killed if the front passengerfront air bag inflates in a collision whichcould occur under some circumstances,even with the air bag technology installedin your vehicle. The only means tocompletely eliminate this risk is to neverplace a child in a rear-facing child restraintin the front seat. We therefore stronglyrecommend that you always place a childin a rear-facing child restraint in a backseat.RIf you must install a rear-facing child

restraint on the front passenger seatbecause circumstances require you to doso, make sure the 4 5 indicatorlamp is illuminated, indicating that the frontpassenger front air bag is deactivated.Should the 4 5 indicator lamp notilluminate or go out while the restraint isinstalled, please check installation.Periodically check the 4 5 indicatorlamp while driving to make sure the 45 indicator lamp is illuminated. If the4 5 indicator lamp goes out orremains out, do not transport a child on thefront passenger seat until the system hasbeen repaired.A child in a rear-facing child restraint on thefront passenger seat will be seriouslyinjured or even killed if the front passengerfront air bag inflates.RIf you have to place a child in a forward-

facing child restraint on the front passengerseat, move the seat as far back as possible,use the proper child restraintrecommended for the age, size and weightof the child, and secure child restraint withthe vehicle's seat belt according to thechild seat manufacturer's instructions.

G WARNINGInfants and small children should never sharea seat belt with another occupant. During anaccident, they could be crushed between theoccupant and seat belt.A child's risk of serious or fatal injuries issignificantly increased if the child restraints

are not properly secured in the vehicle and/or the child is not properly secured in the childrestraint.Children too big for a toddler restraint mustride in seats using regular seat belts. Positionthe shoulder belt across the chest andshoulder, not face or neck. A booster seatmay be necessary to achieve proper seat beltpositioning for children over 41 lb (18 kg) untilthey reach a height where a lap/shoulder beltfits properly without a booster.When the child restraint is not in use, removeit from the vehicle or secure it with the seatbelt to prevent the child restraint frombecoming a projectile in the event of anaccident.

If an infant or child is traveling in the vehicle:X Secure the infant or child with an

appropriate infant or child restraintrecommended for the child's age andweight.

X Make sure that the infant or child isproperly secured at all times while thevehicle is in motion.

front, for vehicle speed and for braking ingood time. Always adapt your driving style tosuit the prevailing road/weather conditions,as well as the traffic conditions and maintaina safe distance to the vehicle in front. Drivecarefully.

i Please note that the driving safetysystems described only work as effectivelyas possible when there is adequate contactbetween the tires and the road surface. Payparticular attention to the informationregarding tires, recommended minimumtire tread depths etc. in the "Wheels andtires" section (Y page 294).In wintry driving conditions, always usewinter tires (M+S tires) and if necessary,snow chains. Only in this way will thedriving safety systems described in thissection work as effectively as possible.

ABS (Anti-lock Braking System)

Important safety notesi Observe the "Important safety notes"

section (Y page 56).ABS regulates brake pressure in such a waythat the wheels do not lock when you brake.This allows you to continue steering thevehicle when braking.ABS works from a speed of about 5 mph(8 km/h) upwards, regardless of road-surfaceconditions. ABS works on slippery surfaces,even when you only brake gently.

G WARNINGIf the ABS malfunctions, other driving systemssuch as the BAS or the ESP® are also switchedoff. Observe indicator and warning lamps thatmay come on as well as messages in themultifunction display that may appear.If the ABS malfunctions, the wheels may lockduring hard braking, reducing the steeringcapability and extending the braking distance.

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

BrakingIf ABS intervenes when braking, you will feela pulsing in the brake pedal.X If ABS intervenes: continue to depress the

brake pedal with force until the brakingsituation is over.

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

The pulsating brake pedal can be anindication of hazardous road conditions, andfunctions as a reminder to take extra carewhile driving.

G WARNINGDo not pump the brake pedal. Use firm, steadybrake pedal pressure instead. Pumping thebrake pedal defeats the purpose of the ABSand significantly reduces brakingeffectiveness.

BAS (Brake Assist System)i Observe the "Important safety notes"

section (Y page 56).BAS operates in emergency brakingsituations. If you depress the brake pedalquickly, BAS automatically boosts the brakingforce, thus shortening the stopping distance.X Keep the brake pedal firmly depressed until

the 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.

G WARNINGIf the BAS malfunctions, the brake system stillfunctions, but without the additional brakeboost available that the BAS would normallyprovide in an emergency braking maneuver.Therefore, the braking distance may increase.

BAS PLUS (Brake Assist System Plus)BAS PLUS is only available in vehiclesequipped with DISTRONIC PLUS.

i Observe the "Important safety notes"section (Y page 56).

At speeds above approximately20 mph (30 km/h), BAS PLUS assists youwhen braking in hazardous situations anduses the radar sensor system to evaluate thetraffic conditions.

i This device has been approved by the FCCas a "Vehicular Radar System". The radarsensor is intended for use in an automotiveradar system only. Removal, tampering, oraltering of the device will void anywarranties, and is not permitted by theFCC. Do not tamper with, alter, or use inany non-approved way.Any unauthorized modification to thisdevice could void the user's authority tooperate the equipment.

With the help of the radar sensor system, BASPLUS can detect obstacles that are in thepath of your vehicle for an extended period oftime.At speeds up to approximately40 mph (70 km/h), BAS PLUS can also detectstationary obstacles, for example stopped orparked vehicles.Should you approach an obstacle and BASPLUS has detected a risk of collision, BASPLUS calculates the braking force necessaryto avoid a rear-end collision. Should you applythe brakes forcefully, BAS PLUS canautomatically increase the braking force to alevel suitable for the traffic conditions.X Keep the brake pedal depressed until the

emergency 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 rear-end

collision.Rno obstacle is detected in front of your

vehicle.BAS PLUS is then deactivated.For BAS PLUS to assist you when driving, theradar sensor system must be switched on andoperational, see "Radar sensor system" in theindex.

G WARNINGBAS PLUS cannot always clearly identifyobjects and complex traffic situations. BASPLUS cannot intervene in these cases.There is a risk of an accident. Always paycareful attention to the traffic situation and beready to brake.

In particular, the detection of obstacles canbe impaired if there is:Rdirt on the sensors or anything else

covering the sensorsRsnow or heavy rainRinterference by other radar sourcesRthe possibility of strong radar reflections,

for example in parking garagesRa narrow vehicle traveling in front, e.g. a

motorbikeRa vehicle traveling in front on a different line

G WARNINGBAS PLUS does not react:Rto people or animalsRto oncoming vehiclesRto crossing trafficRin curvesAs a result, BAS PLUS cannot intervene incritical situations. There is a risk of anaccident. Always pay careful attention to thetraffic situation and be ready to brake.

Following damage to the front end of thevehicle, have the configuration and operation


fety

of the radar sensors checked at a qualifiedspecialist workshop. This also applies tocollisions at low speeds where there is novisible damage to the front of the vehicle.If BAS PLUS is not available due to amalfunction in the radar sensor system, thebrake system remains available with fullbrake boosting effect and BAS.

ESP® (Electronic Stability Program)

Important safety notesi See the "Important safety notes" section

(Y page 56).

If ESP® detects that the vehicle is deviatingfrom the direction desired by the driver, oneor more wheels are braked to stabilize thevehicle. If necessary, the engine output is alsomodified to keep the vehicle on the desiredcourse within physical limits. ESP® assiststhe driver when pulling away on wet orslippery roads. ESP® can also stabilize thevehicle during braking.If ESP® intervenes, the ÷ ESP® warninglamp flashes in the instrument cluster.

G WARNINGUnder no circumstances should youdeactivate ESP® when the ÷ ESP®

warning lamp in the instrument clusterflashes. Proceed as follows:Rwhen driving off, apply as little throttle as

possible.Rwhile driving, ease up on the accelerator

pedal.Radapt your speed to suit the prevailing road

and weather conditions.Failure to observe these guidelines couldcause the vehicle to skid. ESP® cannotprevent accidents resulting from excessivespeed.

! Switch the ignition off when:Rthe parking brake is being tested using a

dynamometerRthe vehicle is being towed with the front

or rear axle raisedApplication of the brakes by ESP® mayotherwise destroy the brake system.

i Only use wheels with the recommendedtire sizes. Only then will ESP® functionproperly.

ETS (Electronic Traction System)i Observe the "Important safety notes"

section (Y page 56).

Traction control is part of ESP®.If the drive wheels spin, traction controlbrakes them individually. This enables you topull away and accelerate on slippery surfaces,for example if the road surface is slippery onone side.Traction control remains active if youdeactivate ESP®.

"ESP® OFF" is designed for driving on closedtracks when the vehicle's natural oversteerand understeer characteristics are desiredand requires a highly skilled and experienceddriver able to handle these critical drivingsituations.You could lose control of your vehicle andcause an accident.Please be aware of these limits when youswitch off the ESP®.Do not switch off the ESP® when a sparewheel is mounted.

ESP® is activated automatically when theengine is started.It may be best to deactivate ESP® in thefollowing situations:Rwhen using snow chainsRin deep snowRon sand or gravel

G WARNINGSwitch on ESP® immediately if one of thepreviously stated conditions is no longer met.Otherwise, ESP® cannot stabilize the vehicleif it begins to lurch or when a wheel spins.

If you deactivate ESP®:RESP® no longer improves driving stability.Rthe engine's torque is no longer limited and

the drive wheels are able to spin. Thespinning of the wheels results in a cuttingaction, which provides better grip.Rtraction control is still activated.RPRE-SAFE® Brake is no longer available,

nor is it activated if you brake firmly andESP® intervenes.RESP® still provides support when you brake

firmly.If ESP® is deactivated and one or more wheelsstart to spin, the ÷ ESP® warning lamp inthe instrument cluster does not flash. In suchsituations, ESP® will not stabilize the vehicle.

EBD (electronic brake forcedistribution)


EBD monitors and controls the brakepressure on the rear wheels to improvedriving stability while braking.

G WARNINGIf EBD has malfunctioned, the braking systemremains available with full brake boostingeffect. However, the rear wheels can still lock,e.g. under full braking. This could cause youto lose control of your vehicle and cause anaccident. You should therefore adapt yourdriving style to the different handlingcharacteristics.

X Observe the notes on warning and indicatorlamps (Y page 230) as well as displaymessages (Y page 204).

ADAPTIVE BRAKEADAPTIVE BRAKE enhances braking safetyand offers increased braking comfort. Inaddition to the braking function, ADAPTIVEBRAKE also has the HOLD function(Y page 159) and hill start assist(Y page 128). For further information, seeDriving tips (Y page 143).

PRE-SAFE® BrakePRE-SAFE® Brake is only available in vehicleswith DISTRONIC PLUS.


PRE-SAFE® Brake can help you to minimizethe risk of a frontal collision with a vehicleahead or reduce the effects of such acollision. If PRE-SAFE® Brake has detected arisk of collision, you will be warned visuallyand acoustically as well as by automaticbraking. PRE-SAFE® Brake cannot prevent acollision without your intervention.At speeds above approximately20 mph (30 km/h), this function warns youwhen you are rapidly approaching the vehiclein front. An intermittent warning tone will


fety

then sound and the · distance warninglamp in the instrument cluster will light up.X Brake immediately in order to increase the

distance from the vehicle in front.orX Take evasive action provided it is safe to do

so.If the driver and front passenger have theirseat belt fastened, PRE-SAFE® Brake can alsobrake the vehicle automatically at speedsfrom approximately 20 mph (30 km/h) toapproximately 124 mph (200 km/h).Due to the nature of the system, particularlycomplicated driving conditions may causeunnecessary warnings or the unnecessaryintervention of PRE-SAFE® Brake. To stop thebraking action, you can either depress theaccelerator pedal further, activate kickdownor release the brake pedal.The braking action of PRE-SAFE® Brake isended automatically if:Ryour speed drops below approximately

9 mph (15 km/h).Ryou maneuver to avoid the obstacle.Rthere is no longer any danger of a rear-end

collision.Rthere is no longer an obstacle detected in

front of your vehicle.

G WARNINGIn order to avoid possible loss of vehiclecontrol, all seat, head restraint, steeringwheel and rear view mirror adjustments, aswell as fastening of seat belts, must be donebefore setting the vehicle in motion.

G WARNINGDo not adjust the driver's seat while driving.Adjusting the seat while driving could causethe driver to lose control of the vehicle.Never travel in a moving vehicle with the seatbackrest in an excessively reclined position asthis can be dangerous. You could slide underthe seat belt in a collision. If you slide underit, the seat belt would apply force at theabdomen or neck. This could cause serious orfatal injuries. The seat backrest and seat beltsprovide the best restraint when the wearer isin a position that is as upright as possible andseat belts are properly positioned on thebody.

G WARNINGYour seat belt must be adjusted so that youcan correctly fasten your seat belt.Observe the following points:Radjust the seat backrest until your arms are

slightly angled when holding the steeringwheel.Radjust the seat to a comfortable seating

position that still allows you to reach theaccelerator/brake pedal safely. Theposition should be as far back as possible

with the driver still able to operate thecontrols properly.Radjust the head restraint so that it is as

close to the head as possible and the centerof the head restraint supports the back ofthe head at eye level.Rnever place hands under the seat or near

any moving parts while a seat is beingadjusted.

Failure to do so could result in an accidentand/or serious personal injury.

G WARNINGThe electrically adjustable seats can beoperated at any time. Therefore, do not leavechildren unattended in the vehicle, or withaccess to an unlocked vehicle. A child'sunsupervised access to a vehicle could resultin an accident and/or serious personal injury.

Important safety notesFor reasons of safety, Mercedes-Benzrecommends that you drive with the lightsswitched on even during the daytime. In somecountries, operation of the headlamps variesdue to legal requirements and self-imposedobligations.

Information about driving abroadConverting to symmetrical low beam when driving abroad: switch the headlampsto symmetrical low beam in countries inwhich traffic drives on the opposite side of theroad to the country where the vehicle isregistered. This prevents glare to oncomingtraffic. Symmetrical lights do not illuminateas large an area of the edge of the road.Have the headlamps converted at a qualifiedspecialist workshop, e.g. an authorizedMercedes-Benz Center, as close to the borderas possible before driving in these countries.Converting to asymmetrical low beam after returning: have the headlampsconverted back to asymmetrical low beam ata qualified specialist workshop, e.g. anauthorized Mercedes-Benz Center, as soon aspossible after crossing the border again.

Overview of climate control systems


G WARNINGSevere conditions (e.g. strong air pollution)may require replacement of the filter beforeits scheduled replacement interval. A cloggedfilter will reduce the air volume to the interiorand the windows could fog up, impairingvisibility and endangering you and others.Have a blocked filter replaced at a Mercedes-Benz Center as soon as possible.

G WARNINGFollow the recommended settings for heatingand cooling given on the following pages.Otherwise, the windows could fog up,impairing visibility and endangering you andothers.

Automatic climate control controls thetemperature and the humidity in the vehicleinterior and filters undesirable substancesfrom the air.Automatic climate control is only operationalwhen the engine is running. Optimumoperation is only achieved if you drive with theside windows and panorama roof with powertilt/sliding panel closed.

i Ventilate the vehicle for a brief periodduring warm weather, e.g. using the

convenience opening feature (Y page 82).This will speed up the cooling process andthe desired vehicle interior temperaturewill be reached more quickly.

i The integrated filter can filter out mostparticles of dust and completely filters outpollen. A clogged filter reduces the amountof air supplied to the vehicle interior. Forthis reason, you should always observe theinterval for replacing the filter, which isspecified in the Service Booklet. As itdepends on environmental conditions, e.g.heavy air pollution, the interval may beshorter than stated in the Service Booklet.

i It is possible that the residual heatfunction may be activated automatically anhour after the SmartKey is removed. Thevehicle is then ventilated for 30 minutes todry the air-conditioning system.

Useful information



Breaking-in notes

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.RDrive at varying vehicle speeds and engine

speeds for the first 1000 miles (1500 km)for this reason.RAvoid overstraining the vehicle during this

period, e.g. driving at full throttle.RChange gear in good time, at the latest

when the tachometer needle is 2/3 of theway to the red area in the tachometerdisplay.RIf possible, drive in drive program E (in AMG

vehicles in drive program C) for the first1000 miles (1500 km).RDo not manually shift to a lower gear to

brake the vehicle.RIf possible, do not depress the accelerator

pedal past the point of resistance(kickdown).ROnly select shift ranges 3, 2 or 1 when

driving slowly, e.g. in mountainous terrain.After 1000 miles (1500 km), you can increasethe engine speed gradually and bring thevehicle up to full speed.

Additional breaking-in notes for AMGvehicles:Rdo not drive faster than 85 mph

(140 km/h) in the first 1000 miles(1500 km).Ronly allow the engine to reach a maximum

engine speed of 4500 rpm briefly.Rchange gear in good time.

i You should also observe these notes onrunning in if the engine or parts of the drivetrain on your vehicle have been replaced.

i Always observe the respective speedrestrictions.

AMG vehicles with rear axle lockingdifferential

Your vehicle is equipped with a self-lockingdifferential on the rear axle. For betterprotection of the differential on the rear axle,carry out an oil change after a breaking-inphase of 2000 miles (3000 km). This oilchange extends the service life of thedifferential. Have the oil change carried outat a qualified specialist workshop. Mercedes-Benz recommends that you use an authorizedMercedes-Benz Center for this purpose.

G WARNINGMake sure absolutely no objects areobstructing the pedals' range of movement.Keep the driver's footwell clear of allobstacles. If there are any floormats orcarpets in the footwell, make sure the pedalsstill have sufficient clearance.During sudden driving or braking maneuversthe objects could get caught between thepedals. You could then no longer brake oraccelerate. This could lead to accidents andinjury.

G WARNINGOn slippery road surfaces, never downshift inorder to obtain braking action. This couldresult in drive wheel slip and reduced vehiclecontrol. Your vehicle's ABS will not preventthis type of loss of control.

G WARNINGIt is dangerous to shift the automatictransmission out of parking position P orneutral position N if the engine speed ishigher than idle speed. If your foot is not firmlyon the brake pedal, the vehicle couldaccelerate quickly forward or in reverse. Youcould lose control of the vehicle and hitsomeone or something. Only shift into gearwhen the engine is idling normally and whenyour right foot is firmly on the brake pedal.

! Warm up the engine quickly. Do not usethe engine's full performance until it hasreached operating 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 oiltemperatures (below 68 ‡ (+20 †), themaximum engine speed is restricted inorder to protect the engine. To protect theengine and maintain smooth engineoperation, avoid driving at full throttle whenthe engine is cold.

General driving tips


G WARNINGAlways remember that you must concentrateprimarily on driving the vehicle. The driver'sconcentration must always be directedprimarily at road traffic. For your own safetyand that of others, we recommend that youstop the vehicle at a safe place and inaccordance with the traffic conditions beforemaking or accepting a phone call.Comply with all legal requirements if you usethe telephone while driving. Use the hands-free system and only use the telephone whenroad, weather and traffic conditions permit. Insome jurisdictions, it is forbidden for driversto use mobile phones while driving.Only operate the audio system or COMAND(Cockpit Management and Data System) incompliance with all legal requirements andwhen the road, weather and traffic conditionspermit. You may otherwise not be able toobserve the traffic conditions, endangeringyourself and others.Remember that your vehicle covers a distanceof 44 feet (approximately 14 m) a secondwhen it is traveling at only 30 mph(approximately 50 km/h).

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

recommended tire pressure.X Remove unnecessary loads.X Remove roof racks when they are not

needed.X Warm up the engine at low engine speeds.X Avoid frequent acceleration or braking.X Have all maintenance work carried out as

indicated by the service intervals in theService Booklet or by the service intervaldisplay.

Fuel consumption also increases whendriving in cold weather, in stop-and-go trafficand in mountainous 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 andjudgment.The possibility of a serious or even fatalaccident are greatly increased when you drinkor take drugs and drive.Do not drink or take drugs and drive or allowanyone to drive who has been drinking ortaking drugs.

Pedals

G WARNINGMake sure absolutely no objects areobstructing the pedals' range of movement.Keep the driver's footwell clear of allobstacles. If there are any floormats orcarpets in the footwell, make sure that thepedals still have sufficient clearance.During sudden driving or braking maneuvers,the objects could get caught between thepedals. You could then no longer brake oraccelerate. This could lead to accidents andinjury.

Rolling with the engine switched off

G WARNINGThere is no power assistance for the steeringand the brake when the engine is not running.Steering and braking requires significantlymore effort and you could lose control of thevehicle and cause an accident as a result.Do not turn off the engine while the vehicle isin motion.

Exhaust check

G WARNINGInhalation of exhaust gas is hazardous to yourhealth. All exhaust gas contains carbonmonoxide (CO), and inhaling it can causeunconsciousness and possible death.Do not run the engine in confined areas (suchas a garage) which are not properly ventilated.If you think that exhaust gas fumes areentering the vehicle while driving, have thecause determined and correctedimmediately. If you must drive under theseconditions, drive only with at least onewindow fully open at all times.

Certain engine systems are designed to keepthe level of poisonous components in exhaustfumes within legal limits.These systems only work at peak efficiencywhen they are maintained exactly inaccordance with the manufacturer'sspecifications. For this reason, all work on theengine must be carried out only by qualifiedand authorized Mercedes-Benz technicians.The engine settings must not be changed inany circumstances. Furthermore, all specificservice work must be carried out at regularintervals and in accordance with theMercedes-Benz service requirements. Detailscan be found in the Service Booklet.

Brakes



G WARNINGMake sure that you do not endanger otherroad users when you apply the brakes.

Downhill gradients! On long and steep gradients, you must

reduce 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 roadsurface. This could cause damage to thedrive train. This type of damage is notcovered by the Mercedes-Benz warranty.

Heavy and light loads

G WARNINGDepressing the brake pedal constantly resultsin excessive and premature wear to the brakepads.It may also cause the brakes to overheat,seriously impairing their effectiveness. It maythen not be possible to stop the vehicle insufficient time to avoid an accident.

If the brakes have been subjected to a heavyload, do not stop the vehicle immediately, butdrive on for a short while. This allows theairflow to cool the brakes more quickly.

Wet roads

G WARNINGAfter driving in heavy rain for some timewithout applying the brakes or through waterdeep enough to wet brake components, thefirst braking action may be somewhatreduced. You have to depress the brake pedalmore firmly. Maintain a safe distance fromvehicles in front.

After driving on a wet road or having thevehicle washed, brake firmly while payingattention to the traffic conditions. This willwarm up the brake discs, thereby drying themmore quickly and protecting them againstcorrosion.

Limited braking performance on salt-treated roads

G WARNINGThe layer of salt on the brake discs and thebrake pads/linings may cause a delay in thebraking effect, resulting in a significantlylonger braking distance, which could lead toan accident.To avoid this danger, you should:Roccasionally brake carefully, without

putting other road users at risk, when youare driving on salted roads. This helps toremove any salt that may have started tobuild up on the brake discs and the brakepads/linings.Rmaintain a greater distance to the vehicle

ahead and drive with particular care.Rcarefully apply the brakes at the end of a

trip and immediately after commencing anew trip, so that salt residues are removedfrom the brake discs.

Servicing the brakes! If the red brake warning lamp lights up in

the instrument cluster and you hear awarning tone while the engine is running,the brake fluid level may be too low.Observe additional warning messages inthe multifunction display.The brake fluid level may be too low due tobrake pad wear or leaking brake lines.Have the brake system checkedimmediately. This work should be carriedout at an authorized Mercedes-BenzCenter.

All checks and maintenance work on thebrake system must be carried out at aqualified specialist workshop. This workshould be carried out at an authorizedMercedes-Benz Center.Have the brake pads replaced and the brakefluid renewed at a qualified specialistworkshop, e.g. an authorized Mercedes-BenzCenter.

G WARNINGIf brake pads or brake fluid other than thoserecommended are used, the brakingproperties of the vehicle can be degraded toan extent that safe braking is substantiallyimpaired. This could result in an accident.

! A function or performance test shouldonly be carried out on a 2-axledynamometer. If you are planning to havethe vehicle tested on such a dynamometer,contact an authorized Mercedes-BenzCenter to obtain further information first.Otherwise, you could damage the drivetrain or the brake system.

! As the ESP® system operatesautomatically, the engine and the ignitionmust be switched off (SmartKey in position0 or 1 in the ignition lock or Start/Stopbutton in position 0 or 1) while the parkingbrake is being tested on a brakedynamometer (maximum 10 seconds).Braking maneuvers triggered automaticallyby ESP® may seriously damage the brakesystem.

! As the ESP® system operatesautomatically, the engine and the ignitionsystem must be switched off (SmartKey inposition 0 or 1 in the ignition lock or Start/Stop button in position 0 or 1) when:Rtesting the parking brake on a brake

dynamometer.Ryou intend to have the vehicle towed with

the front axle raised.Braking maneuvers triggered automaticallyby ESP® may seriously damage the brakesystem.

If your brake system is subject only tomoderate loads, you should test thefunctionality of your brakes at regularintervals by pressing firmly on the brake pedalat high speeds. This improves the grip of thebrake pads.

High-performance brake system forAMG vehiclesThe high-performance brake system isinstalled only on the C 63 AMG.

G WARNINGNew vehicle brake pads and discs, andreplacement brake pads and discs may takeseveral hundred miles of driving until theyprovide optimum braking efficiency. Until thattime, you may need to use increased brakepedal pressure while braking. Please be awareof this and adjust your driving and brakingaccordingly during this break-in period.Excessive high-demand braking will causecorrespondingly high brake wear. Please beattentive to the brake warning lamp in theinstrument cluster and brake conditionmessages in the multifunction display.Especially for high performance driving, it isimportant to maintain and have the brakesystem checked regularly.

The high-performance brake system isdesigned for heavy loads. This may lead tonoise when braking. This will depend on:RspeedRbraking forceRenvironmental conditions, such as

temperature and humidityThe wear of individual components of thebrake system, such as the brake pads/liningsor brake discs, depends on the individualdriving style and operating conditions.For this reason, it is impossible to state amileage that will be valid under allcircumstances. An aggressive driving stylewill lead to high wear. You can obtain further

information about this from your authorizedMercedes-Benz Center.

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 orin conditions in which hydroplaning can occuryou must drive in the following manner:Rreduce your speedRavoid rutsRbrake carefully

Driving on flooded roads! Do not drive through flooded areas.

Check the depth of any water before drivingthrough it. Drive slowly through standingwater. Otherwise, water may enter thevehicle interior or the engine compartment.This can damage the electroniccomponents in the engine or the automatictransmission. Water can also be drawn inby the engine's air suction nozzles and thiscan cause engine damage.

Cruise control

Important safety notesCruise control maintains a constant roadspeed for you. It brakes automatically in orderto avoid exceeding the set speed. On long andsteep downhill gradients, especially if thevehicle is laden, you must select shift range1, 2 or 3 in good time. By doing so, you willmake use of the braking effect of the engine,which relieves the load on the brake systemand prevents the brakes from overheatingand wearing too quickly.Use cruise control only if road and trafficconditions make it appropriate to maintain asteady speed for a prolonged period. You canset any road speed above 20 mph(30 km/h).

G WARNINGThe cruise control is a convenience systemdesigned to assist the driver during vehicleoperation. The driver is and must alwaysremain responsible for the vehicle's speedand for safe brake operation.Only use the cruise control if the road, traffic,and weather conditions make it advisable totravel at a constant speed.RThe use of the cruise control can be

dangerous on winding roads or in heavytraffic because conditions do not allow safedriving at a constant speed.RThe use of the cruise control can be

dangerous on slippery roads. Rapidchanges in tire traction can result in wheelspin and loss of control.RDeactivate the cruise control when driving

you ?, or briefly press up : or down ;.DISTRONIC PLUS is selected.

i DISTRONIC PLUS can only be activated atunder 20 mph (30 km/h) if a vehicle in fronthas been detected. Therefore, theDISTRONIC PLUS distance display in theinstrument cluster should be activated(Y page 192).

X Keep the cruise control lever pressedup : or down ; until the desired speedis set.

i You can use the cruise control lever to setthe stored speed and the control on thecruise control lever to set the specifiedminimum distance (Y page 155).

Pulling awayX If the vehicle in front pulls away: remove

your foot from the brake pedal.X Briefly pull the cruise control lever towards

you ?.orX Accelerate briefly.

Your vehicle pulls away and adapts itsspeed to that of the vehicle in front.

DrivingIf there is no vehicle in front, DISTRONICPLUS operates in the same way as cruisecontrol.If a slower-moving vehicle is detected in front,DISTRONIC causes your vehicle to brake. Thismaintains the preset distance to the vehiclein front.If DISTRONIC PLUS detects a faster-movingvehicle in front, it increases the driving speed

of your vehicle, but only up to the desiredspeed you have stored.

G WARNINGIf you depress the brake, DISTRONIC PLUS isdeactivated unless your vehicle is stationary.DISTRONIC PLUS then no longer brakes yourvehicle. In such cases, control the distancefrom vehicles travelling in front with the brakealone. You could otherwise cause an accidentand thereby injure yourself and others. Thedriver remains fully responsible for thevehicle's distance from other vehicles, thespeed being driven and for braking in goodtime.

Changing lanesIf you wish to change to the passing lane (inleft-hand-drive vehicles, the passing lane isthe left-hand lane), DISTRONIC PLUSsupports you if:Ryou are driving faster than 40 mph

(60 km/h).RDISTRONIC PLUS is maintaining the

distance to a vehicle in front.Ryou switch on the appropriate turn signals.RDISTRONIC PLUS does not detect a danger

of collision.If these conditions are met, your vehicle isaccelerated. Acceleration will be interruptedif changing lanes takes too long or if thedistance between your vehicle and thevehicle in front becomes too small.

G WARNINGDISTRONIC PLUS and Active Blind Spot Assistare only aids designed to assist driving.They do not relieve you of the responsibilityof paying attention. The driver remains fullyresponsible for the vehicle's distance fromother vehicles, the vehicle's speed and forbraking in good time. Always pay attention totraffic conditions and your surroundings.Otherwise, you may fail to recognize dangersin time, cause an accident and injure yourselfand others.

Vehicles with COMANDi The following function is not operational

in all countries.DISTRONIC PLUS uses additional informationfrom your navigation system so that it canreact appropriately to certain trafficsituations. This is the case if, while followinga vehicle, DISTRONIC PLUS is active and you:Rapproach or drive through a traffic circleRapproach a T intersectionRturn off at a freeway exitEven if the vehicle in front leaves thedetection range, DISTRONIC PLUStemporarily maintains the current drivingspeed and does not accelerate. This is basedon the current map data in the navigationsystem.

Example: traffic circle

The current speed is maintained:Rapproximately 10 seconds before the

traffic circle/T intersection and forapproximately 1.5 seconds when driving onthe traffic circleRapproximately 12 seconds before reaching

a freeway exit and approximately4 seconds after the freeway exit

Tips for driving with DISTRONIC PLUS

Important safety notesThe following contains descriptions of certainroad and traffic conditions in which you mustbe particularly attentive. In such situations,brake if necessary. DISTRONIC PLUS is thendeactivated.

G WARNINGThe DISTRONIC PLUS works to maintain thespeed selected by the driver unless a movingobstacle proceeding directly ahead of it in thesame travel direction is detected (e.g.following another vehicle ahead of you at yourset distance).

This means that:RYour vehicle can pass another vehicle after

you have changed lanes.RWhile in a sharp turn or if the preceding

vehicle is in a sharp turn, the DISTRONICPLUS could lose sight of the precedingvehicle. Your vehicle could then accelerateto the previously selected speed.

The DISTRONIC PLUS regulates only thedistance between your vehicle and thosedirectly ahead of it. It may not registerstationary objects in the road, e.g.:Ra stopped vehicle in a traffic jamRa disabled vehicleRan oncoming vehicleThe driver must always be alert, observe alltraffic and intercede as required by means ofsteering or braking the vehicle.

G WARNINGThe DISTRONIC PLUS should not be used insnowy or icy road conditions.

Cornering, going into and coming out of abend

The ability of DISTRONIC PLUS to detectvehicles when cornering is limited. Yourvehicle may 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 lane

DISTRONIC PLUS has not detected thevehicle cutting in yet. The distance to thisvehicle will 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 forobstacles or stationary vehicles. If, forexample, the detected vehicle turns a cornerand reveals an obstacle or stationary vehicle,DISTRONIC PLUS will not brake for these.

Crossing vehicles

DISTRONIC PLUS may mistakenly detectvehicles that are crossing your lane.Activating DISTRONIC PLUS at traffic lightswith crossing traffic, for example, could causeyour vehicle to pull away unintentionally.

cause an accident and injure yourself andothers.Safety always remains your responsibility andyou must continue paying careful attention toyour immediate surroundings when parkingand maneuvering.

G WARNINGObjects located above the height range ofParking Guidance will not be detected whenthe parking space is measured. These objectsare not taken into account when the parkingprocedure is calculated, e.g. overhangingloads, tail sections or loading ramps of goodsvehicles. Under some circumstances, ParkingGuidance might therefore issue steeringinstructions too soon. This may lead to acollision. For this reason, you should avoidusing Parking Guidance in such situations.

G WARNINGMake sure that no persons or animals are inthe maneuvering range. Otherwise, theycould be injured.

! Pay particular attention to low objects orobjects with flat surfaces, such as trailerdrawbars, posts, cross beams and curbs.These types of objects cannot be detectedby Parking Guidance and may damage thevehicle.

When PARKTRONIC is deactivated, ParkingGuidance is also unavailable.Use Parking Guidance for parking spaces:Rthat are parallel to the direction of travelRthat are on straight roads, not bendsRthat are on the same level as the road, i.e.

not on the pavement, for example. ParkingGuidance may not detect flat curbs

Parking tips:Ron narrow roads, drive past the parking

space as close as possible.Rparking spaces that are littered, overgrown

or partially occupied by trailer drawbarsmight be identified incorrectly or not at all.

Rsnowfall or heavy rain may lead to a parkingspace being measured inaccurately.Rpay attention to the PARKTRONIC

(Y page 163) warning messages during theparking procedure.Rwhen transporting a load which protrudes

from your vehicle, you must not use ParkingGuidance.Rnever use Parking Guidance with snow

chains or an emergency spare wheelmounted.Rmake sure that the tire pressures are

always correct. This has a direct effect onthe steering instructions.Rthe way your vehicle is positioned in the

parking space after parking is dependenton various factors. These include theposition and shape of the vehicles parkedin front and behind it and the conditions ofthe location. In some cases, ParkingGuidance may guide you too far or not farenough into a parking space. In somecases, it may also lead you across or ontothe curb. If necessary, cancel the parkingprocedure with Parking Guidance.

! If unavoidable, you should drive overobstacles such as curbs slowly and not ata sharp angle. Otherwise, you may damagethe wheels or tires.

ATTENTION ASSIST

Important safety notesATTENTION ASSIST helps you during long,monotonous journeys such as on freewaysand interstate highways. It is active in therange between 50 mph (80 km/h) and112 mph (180 km/h).If ATTENTION ASSIST detects typicalindicators of fatigue or increasing lapses inconcentration on the part of the driver, itsuggests you take a break.

G WARNINGATTENTION ASSIST is only an aid and maydetect your tiredness or lapses inconcentration too late or not at all. It is not asubstitute for a well-rested and attentivedriver.Fatigue may cause you to recognizehazardous situations too late, misjudge asituation or react more slowly. For thisreason, make sure you feel rested before youbegin driving and during your journey. Makesure that you take regular breaks in time,particularly on long journeys. Otherwise, youmay fail to recognize dangers in time, causean accident and injure yourself and others.

ATTENTION ASSIST assesses your level offatigue or lapses in concentration by takingthe following criteria into account:Ryour personal driving style, e.g. steering

characteristicsRdriving conditions, e.g. time, driving time

Lane Tracking package

General notesThe Lane Tracking package consists of BlindSpot Assist (Y page 170) and Lane KeepingAssist (Y page 172).

Blind Spot Assist

Important safety notesBlind Spot Assist uses a radar sensor systemto monitor the areas on both sides of yourvehicle. It supports you from speeds ofapproximately 20 mph (30 km/h). A warningdisplay in the exterior mirrors draws yourattention to vehicles detected in themonitored area. If you then switch on thecorresponding turn signal to change lane, youwill also receive an optical and audiblecollision warning. Blind Spot Assist usessensors in the rear bumper for monitoringpurposes.

G WARNINGBlind Spot Assist is only an aid designed toassist driving. It may fail to detect somevehicles and is no substitute for attentivedriving.Blind Spot Assist cannot detect road andtraffic conditions. It may fail to detect narrowvehicles, such as motorcycles or bicycles, ormay only detect them too late.Monitoring may be affected by dirty sensors,strong spray or poor visibility caused by snow,

rain or mist, for example. In this case, vehiclesare detected late or not at all.Always pay attention to traffic conditions andyour surroundings. Otherwise, you may fail torecognize dangers in time, cause an accidentand injure yourself and others.


For Blind Spot Assist to assist you whendriving, the radar sensor system must beactivated (Y page 196) and operational.

Monitoring range of the sensorsBlind Spot Assist monitors the area shown inthe figure up to 10 ft (3 m) behind andimmediately adjacent to your vehicle.

G WARNINGBlind Spot Assist monitors certain areas in theimmediate vicinity of your vehicle. Vehicles

that approach and drive past at high speedsare not detected. There is no display and nowarning.If the lanes are very wide, it may not bepossible to monitor the complete width of theneighboring lane. For this reason, vehicles inthe next lane may not be detected, especiallyif they are driving in a staggered formation.This may be the case if vehicles are driving atthat edge of their lane which is furthest awayfrom your vehicle.Always pay attention to traffic conditions andyour surroundings. Otherwise, you may fail torecognize dangers in time, cause an accidentand injure yourself and others.

If the lanes are narrow, vehicles driving in thelane beyond the lane next to your vehicle maybe indicated, especially if the vehicles are notdriving in the middle of their lane. This maybe the case if the vehicles are driving on theinner side of their lane.Due to the nature of the system:Rwarnings may be issued in error when

driving close to crash barriers or similarsolid lane borders.Rwarnings may be interrupted when driving

alongside long vehicles, such as trucks, fora prolonged time.

The two sensors for Blind Spot Assist areintegrated into the sides of the rear bumper.Make sure that the bumper is free from dirt,ice or slush around the sensors. The rearsensors must not be covered, for example bybicycle racks or overhanging loads. Followinga severe impact or in the event of damage tothe bumpers, have the function of the radarsensors checked at a qualified specialistworkshop, e.g. an authorized Mercedes-BenzCenter. Blind Spot Assist may otherwise notwork properly.

The tire pressure monitor is faulty.X Observe the additional display messages in the multifunction

G WARNINGEach tire, including the spare (if provided), should be checked at least every two weeks whencold and inflated to the pressure recommended by the vehicle manufacturer on the Tire andLoading Information placard on the driver's door B-pillar or, if available, the tire pressure labelon the inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicatedon the Tire and Loading Information placard or the tire pressure label, you should determine theproper tire pressure for those tires.As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pressure telltale when one or more of your tires aresignificantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible, and inflate them to the proper pressure. Drivingon a significantly underinflated tire causes the tire to overheat and can lead to tire failure.Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handlingand stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance,and it is the driver's responsibility to maintain correct tire pressure, even if underinflation hasnot reached the level to trigger illumination of the TPMS low tire pressure telltale.USA only:Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS malfunction indicator is combined with the low tirepressure telltale. When the system detects a malfunction, the telltale will flash for approximately1 minute and then remain continuously illuminated. This sequence will be repeated every time

the vehicle is started as long as the malfunction exists. When the malfunction indicator isilluminated, the system may not be able to detect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety of reasons, including the installation of incompatiblereplacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioningproperly. Always check the TPMS malfunction telltale after replacing one or more tires or wheelson your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS tocontinue to function properly.

For this reason, youalso should not pull or push the battery overcarpets or other synthetic materials.Never touch the battery first. First, touch theoutside body of the vehicle in order to releaseany possible electrostatic charges.Do not rub the battery with rags or cloths. Thebattery could explode if touched due to

electrostatic charge or due to sparkformation.

! Before working on the battery, e.g.loosening the battery terminals, switch offthe engine and remove the SmartKey fromthe ignition. On vehicles with KEYLESS-GO,make sure that the ignition is switched off.Check that all the indicator lamps in theinstrument cluster are off. You mayotherwise destroy electronic components,such as the alternator.

! Like other batteries, the vehicle batterymay discharge over time if you do not usethe vehicle. In this case have the batterychecked at a qualified specialist workshop,such as an authorized Mercedes-BenzCenter. You can also charge the batterywith a charger recommended by Mercedes-Benz. Contact an authorized Mercedes-Benz Center for more information.The battery and the cover of the positiveterminal clamp must be installed securelyduring operation.

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

Mercedes-Benz recommends that you do notcarry out work on batteries yourself, e.g.removing or charging. Always have this workperformed at a qualified specialist workshop,e.g. an authorized Mercedes-Benz Center.

i If the power supply has been interrupted,e.g. if the battery has been reconnected,you must carry out the following tasks:Rset the clock; see the separate operating

instructions.Rreset the function for automatically

Jump-starting

G WARNINGFailure to follow these directions will cause damage to the electronic components, and can leadto a battery explosion and severe injury or death.Never lean over batteries while connecting or jump starting. You might get injured.Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin orclothing. In case it does, immediately flush affected area with water, and seek medical help ifnecessary.A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames orsparks away from battery, avoid improper connection of jumper cables, smoking, etc.Attempting to jump start a frozen battery can result in it exploding, causing personal injury.Read all instructions before proceeding.

! Avoid repeated and lengthy starting attempts. Otherwise, non-combusted fuel maydamage the catalytic converter18 and create a risk of fire.Do not use a rapid-charging device to start the engine.Make sure the jumper cables are not damaged.Make sure the jumper cables are not touching any other metal objects when they areconnected to the battery.

If your vehicle's battery is discharged, the engine can be jump-started from another vehicleor from a second battery using jumper cables.Observe the following points:X The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,

jump-start the vehicle using a second battery or a jump-starting device.X Only jump-start the vehicle when the engine is cold and the catalytic converter system has

cooled down19.X Do not start the engine if the battery is frozen. Let the battery thaw first.X Jump-starting may only be performed from batteries with a nominal voltage of 12 V.X Only use jumper cables which have a sufficient cross-section and insulated terminal clamps.X Make sure that the jumper cables cannot come into contact with parts, such as the pulley

or the fan. These parts move when the engine is started and while it is running.X If the battery is fully discharged, leave the battery that is being used to jump-start connected

for a few minutes before attempting to start. This charges the empty battery a little.

Useful information




Consult an authorized Mercedes-Benz Centerif you require information on approved andrecommended tires and wheels for summerand winter operation. Advice on purchasingand caring for tires is also available there.

G WARNINGReplace rims or tires with the samedesignation, manufacturer and type as shownon the original part. For further informationcontact an authorized Mercedes-Benz Center.If incorrectly sized rims and tires aremounted, the wheel brakes or suspensioncomponents can be damaged. Also, theoperating clearance of the wheels and thetires may no longer be correct.

G WARNINGWorn, old tires can cause accidents. If the tiretread is worn to minimum tread depth, or ifthe tires have sustained damage, replacethem.When replacing rims, only use genuineMercedes-Benz wheel bolts specified for theparticular rim type. Failure to do so can resultin the bolts loosening and possibly anaccident.Retreaded tires are not tested orrecommended by Mercedes-Benz, sinceprevious damage cannot always be

recognized on retreads. The operating safetyof the vehicle cannot be assured when suchtires are used.

G WARNINGIf you feel a sudden significant vibration orride disturbance, or you suspect that possibledamage to your vehicle has occurred, youshould turn on the hazard warning flashers,carefully slow down, and drive with caution toan area which is a safe distance from the road.Inspect the tires and the vehicle underbodyfor possible damage. If the vehicle appearsunsafe, have the vehicle towed to the nearestauthorized Mercedes-Benz Center or tiredealer for repairs.

G WARNINGDo not drive with a flat tire. A flat tire affectsthe ability to steer or brake the vehicle. Youmight lose control of the vehicle. Continueddriving with a flat tire or driving at high speedwith a flat tire will cause excessive heat build-up and possibly a fire.

i Further information about Tires andwheels can be obtained from anyauthorized Mercedes-Benz Center.

Operation

Notes on drivingRIf the vehicle is heavily laden, check the tire

pressures and correct them if necessary.RWhen parking your vehicle, make sure that

the tires do not get deformed by the curbor other obstacles. If it is necessary to driveover curbs, speed humps or similarelevations, try to do so slowly and at anobtuse angle. Otherwise, the tires,particularly the sidewalls, can getdamaged.

Notes on regularly inspecting wheelsand tires

G WARNINGRegularly check the tires for damage.Damaged tires can cause tire inflationpressure loss. As a result, you could losecontrol of your vehicle.Worn, old tires can cause accidents. If the tiretread is worn to minimum tread depth, or ifthe tires have sustained damage, replacethem.

RRegularly check the wheels and tires ofyour vehicle for damage (e.g. cuts,punctures, tears, bulges on tires anddeformation or cracks or severe corrosionon wheels) at least once a month, as wellas after driving off-road or on rough roads.Damaged wheels can cause a loss of tirepressure.RRegularly check the tire tread depth and

the condition of the tread across the wholewidth of the tire (Y page 295). If necessary,turn the front wheels to full lock in order toinspect the inner side of the tire surface.RAll wheels must have a valve cap to protect

the valve against dirt and moisture. Do notmount anything onto the valve (such as tirepressure monitoring systems) other thanthe standard valve cap or other valve capsapproved by Mercedes-Benz for yourvehicle.RRegularly check the pressure of all the tires

including the emergency spare wheel or thespare wheel, particularly prior to long trips,and correct the pressure as necessary(Y page 297).

Tire tread

G WARNINGAlthough the applicable federal motor vehiclesafety laws consider a tire to be worn whenthe tread wear indicators (TWI) becomevisible at approximately 1/16 in (1.6 mm), we

recommend that you do not allow your tiresto wear down to that level. As tread depthapproaches 1/8 in (3 mm), the adhesionproperties on a wet road are sharply reduced.Depending upon the weather and/or roadsurface (conditions), the tire traction varieswidely.

Do not use tires that are excessively worn asthe tire traction on wet road surfacesdecreases significantly when the tread depthis less than 1/8 inch (3 mm).Tread wear indicators (TWI) are required bylaw. Six indicators are positioned on the tiretread. They become visible as soon as a treaddepth of approximately 1/16 inch (1.6 mm)has been reached. If this is the case, the tireis so worn that it must be replaced.The recommended tread depth for summertires is at least 1/8 inch (3 mm). Therecommended tread depth for winter tires isat least 1/6 inch (4 mm).

Bar marking : for tread wear is integratedinto the tire tread.

Notes on selecting, mounting andreplacing tiresROnly mount tires and wheels of the same

type and make.ROnly mount tires of the correct size onto

the wheels.RAfter mounting new tires, run them in at

as the tire traction on wet road surfacesdecreases significantly when the treaddepth is less than 1/8 inch (3 mm).RReplace the tires after six years at the

latest, regardless of wear. This also appliesto the spare wheel/emergency sparewheel.

The service life of tires depends on thefollowing factors amongst other things:Rdriving styleRtire pressureRmileage

MOExtended tires (tires with run-flatproperties)

MOExtended tires (tires with run-flatproperties) allow you to continue driving yourvehicle even if one or more tires are entirelydeflated.MOExtended tires may be used only inconjunction with the activated tire pressureloss warning system or the activated tirepressure monitoring system and only onwheels specifically tested by Mercedes-Benz.You will find notes on driving withMOExtended tires in the "Breakdownassistance" section (Y page 283).

Winter operation

Please bear the following in mindAt the onset of winter, have your vehiclewinterproofed at a qualified specialistworkshop, e.g. at an authorized Mercedes-Benz Center.Observe the notes in the "Changing a wheel"section (Y page 318).

Driving with summer tiresAt temperatures below 45 ‡ (+7 †), theelasticity of summer tires and therefore alsotraction and braking capability are reducedconsiderably — equip your vehicle withM+S tires. Using summer tires at very coldtemperatures could cause tears to form,thereby damaging the tires permanently.Mercedes-Benz cannot accept responsibilityfor this type of damage.

M+S tiresAt temperatures below 45 ‡(+7 †), usewinter tires or all-season tires. Both types oftire are identified by the M+S marking.Only winter tires bearing the i snowflakesymbol in addition to the M+S markingprovide the best possible grip in wintry roadconditions. Only these tires will allow drivingsafety systems such as ABS and ESP® tofunction optimally in winter. These tires havebeen developed specifically for driving insnow.Use M+S tires of the same make and tread onall wheels to maintain safe handlingcharacteristics.

G WARNINGM+S tires with a tread depth of less than1/6 inch (4 mm) must be replacedimmediately. They are no longer suitable foruse in winter.

Always observe the maximum permissiblespeed specified for the M+S tires you havemounted.When you have mounted M+S tires:X Check the tire pressures (Y page 301).X Vehicles for Canada: restart the tire

pressure loss warning system(Y page 301).

X Restart the tire pressure monitor(Y page 303).

G WARNINGIf you use your spare wheel when M+S tiresare mounted on the other wheels, be awarethat the difference in tire characteristicsimpairs cornering ability and reduces drivingstability. Adapt your driving style accordingly.Have the spare wheel replaced by a normalwheel with an M+S tire at the nearestMercedes-Benz Center.

Snow chainsFor safety reasons, Mercedes-Benzrecommends that you only use snow chainswhich have been specially approved for yourvehicle by Mercedes-Benz, or are of acorresponding standard of quality.

! There is not enough space for snowchains on some wheel sizes. Observe theinformation under "Tires and wheels" in the"Technical Data" section to avoid damageto the vehicle or the wheels.ROnly use snow chains when driving on

roads completely covered by snow. Do notexceed the maximum permissible speed of30 mph (50 km/h). Remove the snowchains as soon as possible when you are nolonger driving on snow-covered roads.RLocal regulations may restrict the use of

snow chains. Applicable regulations mustbe observed if you wish to mount snowchains.RSnow chains must not be mounted on

emergency spare wheels.If you intend to mount snow chains, pleasebear the following points in mind:Ryou may not attach snow chains to all

wheel-tire combinations; see theinformation under "Wheel and tirecombinations" in the "Wheels and tires"section.Rmount snow chains only in pairs and only

to the rear wheels. Observe themanufacturer's installation instructions.

! If snow chains are mounted on the frontwheels, the snow chains could grindagainst the bodywork or components of thechassis. This could result in damage to thevehicle or the tires.

! Vehicles with steel wheels: if you wishto mount snow chains on steel wheels,make sure that you remove the respectivewheels' hubcaps first. The hubcaps mayotherwise be damaged.

i You may wish to deactivateESP®(Y page 59) when pulling away withsnow chains mounted. This way you canallow the wheels to spin in a controlledmanner, achieving an increased drivingforce (cutting action).

Important notes on tire pressure

G WARNINGShould the tire pressure drop repeatedly:Rcheck the tire for foreign bodies.Rcheck whether the wheel is losing air or the

valve is leaking.Rmake sure that only a valve cap approved

by Mercedes-Benz is used on the tire valve.Tire pressures that are too low have anegative effect on vehicle safety, which couldlead you to cause an accident.

To test tire pressure, use a suitable tirepressure gauge. The outer appearance of atire does not permit any reliable conclusionabout the tire pressure. On vehicles equippedwith the electronic tire pressure monitoringsystem, the tire pressure can be checkedusing the on-board computer.The tire temperature and pressure increasewhen the vehicle is in motion. This isdependent on the driving speed and the load.Therefore, you should only correct tirepressures when the tires are cold.The tires are cold:Rif the vehicle has been parked without

direct sunlight on the tires for at least threehours andRif the vehicle has not been driven more than

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 whenchecking the pressure of warm tires and onlycorrect the tire pressure if it is too low for thecurrent operating conditions. If you check thetire pressure when the tires are warm, theresulting value will be higher than if the tireswere cold. This is normal. Do not reduce thetire pressure to the value specified for coldtires. The tire pressure would otherwise betoo low.

Tire pressure loss warning system(Canada only)

Important safety notesWhile the vehicle is in motion, the tirepressure loss warning system monitors theset tire pressure using the rotational speed ofthe wheels. This enables the system to detectsignificant pressure loss in a tire. If the speedof rotation of a wheel changes as a result ofa loss of pressure, a corresponding warningmessage will appear in the multifunctiondisplay.

G WARNINGIf the Check Tire Pressure Soon messageappears in the multifunction display, one ormore tires are significantly underinflated.Stop the vehicle as soon as possible andinflate the tires to the pressure specified onthe vehicle's Tire and Loading Informationplacard or (where available) in the tirepressure table.Driving on a significantly underinflated tirecauses the tire to overheat and can lead totire failure. Underinflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle's handling and stopping ability.Check all tires when cold, including the sparetire, at least once a month. The tires shouldbe inflated to the recommended pressure.This information can be found:Ron the Tire and Loading Information placard

G WARNINGThe tire pressure loss warning system doesnot provide a warning for wrongly selected tireinflation pressures. Always adjust tireinflation pressure according to the Tire andLoading Information placard on the driver'sdoor B-pillar or on the tire inflation pressurelabel located on the inside of the fuel filler flap.The tire pressure loss warning system doesnot replace regular checks of the tire inflationpressures since a gradual pressure loss inmore than one tire cannot be detected by thetire pressure loss warning system.The tire pressure loss warning system is notable to issue a warning due to a suddendramatic loss of tire inflation pressure (e.g.tire blowout caused by a foreign object). Inthis case bring the vehicle to a halt by carefullyapplying the brakes and avoiding abruptsteering maneuvers.

The function of the tire pressure loss warningsystem is limited or delayed if:Rsnow chains are mounted to your vehicle's

tires.Rroad conditions are wintry.Ryou are driving on sand or gravel.Ryou adopt a very sporty driving style

(cornering at high speeds or driving withhigh rates of acceleration).Ryou are driving with a heavy load (in the

Tire pressure monitor

Important safety notesIf a tire pressure monitor system is installed,the vehicle's wheels have sensors thatmonitor the tire pressures in all four tires. Thetire pressure monitor warns you if thepressure drops in one or more of the tires. Thetire pressure monitor only functions if thecorrect wheel electronics units are installedon all wheels.The tire pressure monitor has a yellowwarning lamp in the instrument cluster forindicating pressure loss/malfunctions (USA)or pressure loss (Canada). Whether thewarning lamp flashes or lights up indicateswhether a tire pressure is too low or the tirepressure monitoring system ismalfunctioning:Rif the warning lamp is lit continuously, the

tire pressure on one or more tires issignificantly too low. The tire pressuremonitor is not malfunctioning.RUSA only: if the warning lamp flashes for

60 seconds and then remains lit constantly,the tire pressure monitor is malfunctioning.

G WARNINGEach tire, including the spare (if provided),should be checked at least once a monthwhen cold and inflated to the pressurerecommended by the vehicle manufactureron the Tire and Loading Information placardon the driver's door B-pillar or the tirepressure label on the inside of the fuel fillerflap. If your vehicle has tires of a different sizethan the size indicated on the Tire and LoadingInformation placard or the tire pressure label,you should determine the proper tire pressurefor those tires.

As an added safety feature, your vehicle hasbeen equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires are significantly underinflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop and checkyour tires as soon as possible, and inflatethem to the proper pressure. Driving on asignificantly underinflated tire causes the tireto overheat and can lead to tire failure.Underinflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability.Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver's responsibility to maintain correct tirepressure, even if underinflation has notreached the level to trigger illumination of theTPMS low tire pressure telltale.USA only: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 thesystem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will be repeated every time thevehicle is started as long as the malfunctionexists.When the malfunction indicator is illuminated,the system may not be able to detect or signallow tire pressure as intended. TPMSmalfunctions may occur for a variety ofreasons, including the installation ofincompatible replacement or alternate tiresor wheels on the vehicle that prevent theTPMS from functioning properly. Alwayscheck the TPMS malfunction telltale afterreplacing one or more tires or wheels on yourvehicle to ensure that the replacement oralternate tires and wheels allow the TPMS tocontinue to function properly.

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

combined 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 XXXkilograms or XXX lbs.

X Step 4: The resulting figure equals theavailable amount of cargo and luggage loadcapacity. For example, if the "XXX" amountequals 1400 lbs and there will be five150 lbs passengers in your vehicle, theamount of available cargo and luggage loadcapacity is 650 lbs (1400 - 750 (5 x 150) =650 lbs).

X Step 5: Determine the combined weight ofluggage and cargo being loaded on thevehicle. That weight may not safely exceedthe available cargo and luggage loadcapacity calculated in step 4.

X Step 6 (if applicable): If your vehicle willbe towing a trailer, load from your trailerwill be transferred to your vehicle. Consultthis manual to determine how this reducesthe available cargo and luggage loadcapacity of your vehicle (Y page 309).

Uniform Tire Quality GradingStandards

Overview of Tire Quality GradingStandards

The Uniform Tire Quality Grading is a U.S.Government requirement. Their purpose is toprovide drivers with consistent and reliableinformation regarding tire performance. Tiremanufacturers are required to grade tiresusing three performance factors: treadwear :, tire traction ;, and temperatureresistance =. Although not a Government ofCanada requirement, all tires made for sale inNorth America have these grades branded onthe sidewall.

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

Where applicable, the tire gradinginformation can be found on the tire sidewallbetween the tread shoulder and maximumtire width.For example:

Tread wear Traction Temperature

200 AA A

All passenger car tires must conform to thestatutory safety requirements in addition tothese grades.

Tread wearThe tread wear grade is a comparative ratingbased on the wear rate of the tire when testedunder controlled conditions on a specifiedU.S. Government test course. For example, atire graded 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,however, and may depart significantly fromthe norm, due to variations in driving habits,service practices and differences in roadcharacteristics and climate conditions.

Traction

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

The traction grades, from highest to lowest,are AA, A, B, and C. Those grades representthe tire's ability to stop on a wet surface asmeasured under controlled conditions onspecified government test surfaces of asphaltand concrete. A tire marked C may have poortraction performance.

G WARNINGIf ice has formed on the road, tire traction willbe substantially reduced. Under such weatherconditions, drive, steer and brake withextreme caution.

The safe speed on a wet, snow covered or icyroad is always lower than on dry roadsurfaces.You should pay special attention to roadconditions when temperatures are aroundthe freezing point.Mercedes-Benz recommends a minimum tiretread depth of 1/6 in (4 mm) for all four winter

tires (Y page 296) to maintain normal drivingcharacteristics in winter. Winter tires canreduce the braking distance on snow coveredsurfaces in comparison to summer tires.Stopping distance, however, is stillconsiderably greater than when the road isnot covered with ice or snow. Takeappropriate care when driving.

! Avoid wheelspin. This can lead to damageto the drive train.

Temperature

G WARNINGThe temperature grade for this tire isestablished for a tire that is properly inflatedand not overloaded. Excessive speed,underinflation, or excessive loading, eitherseparately or in combination, can causeexcessive heat build-up and possible tirefailure.

The temperature grades are A (the highest),B, and C. These represent the tire'sresistance to the generation of heat and itsability to dissipate heat when tested undercontrolled conditions on a specified indoorlaboratory test wheel. Sustained hightemperature can cause the material of the tireto degenerate and reduce tire life, andexcessive temperature can lead to suddentire failure. The grade C corresponds to a levelof performance which all passenger car tiresmust meet under the Federal Motor VehicleSafety Standard No. 109. Grades B and Arepresent higher levels of performance on thelaboratory test wheel than the minimumrequired by law.

Increased vehicle weight due tooptional equipment

This is the combined weight of all standardand optional equipment available for thevehicle, regardless of whether it is actuallyinstalled on the vehicle or not.

RimThis is the part of the wheel on which the tireis mounted.

GAWR (Gross Axle Weight Rating)The GAWR is the maximum permissible axleweight. The actual load on an axle must neverexceed the gross axle weight rating. Thegross axle weight rating can be found on thevehicle identification plate on the B-pillar onthe driver's side.

Speed ratingThe speed rating is part of the tireidentification. It specifies the speed range forwhich the tire is approved.

GVW (Gross Vehicle Weight)The gross vehicle weight comprises theweight of the vehicle including fuel, tools, thespare wheel, accessories installed,occupants, luggage and the drawbarnoseweight, if applicable. The gross vehicleweight must not exceed the gross vehicleweight rating GVWR as specified on thevehicle identification plate on the B pillar onthe driver's side.

GVWR (Gross Vehicle Weight Rating)The GVWR is the maximum permissible grossweight of a fully loaded vehicle (the weight ofthe vehicle including all accessories,occupants, fuel, luggage and the drawbar

noseweight, if applicable). The gross vehicleweight rating is specified on the vehicleidentification plate on the B-pillar on thedriver's side.

Maximum loaded vehicle weightThe maximum weight is the sum of the curbweight of the vehicle, the weight of theaccessories, the total load limit and theweight of the optional equipment installed atthe factory.

Kilopascal (kPa)Metric unit for tire pressure. 6.9 kPa is theequivalent of 1 psi. Another unit for tirepressure is bar. There are 100 kilopascals(kPa) to 1 bar.

Load indexIn addition to the load bearing index, the loadindex may also be imprinted on the sidewallof the tire. This specifies the load bearingcapacity more precisely.

Curb weightThe weight of a vehicle with standardequipment including the maximum capacityof fuel, oil and coolant. It also includes the air-conditioning system and optional equipmentif these are installed in the vehicle, but doesnot include passengers or luggage.

Maximum load ratingThe maximum load rating in kilograms orpounds is the maximum weight for which atire is approved.

Maximum permissible tire pressureMaximum permissible tire pressure for onetire.

Maximum load on one tireMaximum load on one tire. This is calculatedby dividing the maximum axle load of one axleby two.

PSI (pounds per square inch)A standard unit of measure for tire pressure.

Aspect ratioRelationship between tire height and tirewidth in percent.

Tire pressureThis is pressure inside the tire applying anoutward force to each square inch of the tire'ssurface. The tire pressure is specified inpounds per square inch (psi), in kilopascal(kPa) or in bar. The tire pressure should onlybe corrected when the tires are cold.

Tire pressure of cold tiresThe tires are cold:Rif the vehicle has been parked without

direct sunlight on the tires for at least threehours andRif the vehicle has not been driven more than

1 mile (1.6 km).

TreadThe part of the tire that comes into contactwith the road.

BeadThe tire bead ensures that the tire sitssecurely on the wheel. There are several steelwires in the bead to prevent the tire fromcoming loose from the wheel rim.

SidewallThe part of the tire between the tread and thebead.

Weight of optional extrasThe combined weight of those optional extrasthat weigh more than the replaced standardpart and more than 2.3 kilograms (5 lbs).These optional extras, such as high-performance brakes, level control, a roof rackor a high-performance battery, are notincluded in the curb weight and accessoryweight.

TIN (Tire Identification Number)This is a unique identifier which can be usedby a tire manufacturer to identify tires, forexample for a product recall, and thus identifythe purchasers. The TIN is made up of themanufacturer's identity code, tire size, tiretype code and the manufacturing date.

Load bearing indexThe load bearing index (also load index) is acode that contains the maximum load bearingcapacity of a tire.

TractionTraction is the result of friction between thetires and the road surface.

Total load limitRated cargo and luggage load plus68 kilograms (150 lbs) times the vehicle'sdesignated seating capacity.

Changing a wheel

Flat tireThe "Breakdown assistance" section(Y page 279) contains information and noteson how to deal with a flat tire. It also providesinstructions on changing a wheel or mountingthe spare wheel/emergency spare wheel.

Interchanging the wheels

G WARNINGRotate front and rear wheels only if the tiresare of the same dimension.If your vehicle is equipped with mixed-sizetires (different tire dimensions front vs. rear),tire rotation is not possible.

G WARNINGHave the tightening torque checked afterchanging a wheel. Wheels could becomeloose if not tightened with a torque of96 lb-ft (130 Nm).Only use genuine Mercedes-Benz wheel boltsspecified for your vehicle's rims.

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 theintervals in the tire manufacturer's warrantybook in your vehicle documents. If this is notavailable, the tires should then be replacedevery 3000 to 6000 miles(5000 to 10,000 km), or earlier if the tire wearrequires this. Do not change the direction ofwheel rotation.Clean the contact surfaces of the wheel andthe brake disc thoroughly every time a wheelis interchanged. Check the tire pressures.Information on changing a wheel andmounting the spare wheel (Y page 279).

! On vehicles equipped with a tire pressuremonitor, electronic components arelocated in the wheel.Tire-mounting tools should not be usednear the valve. This could damage theelectronic components.Always have the tires changed at a qualifiedspecialist workshop, e.g. an authorizedMercedes-Benz Center.

Direction of rotationTires with a specified direction of rotationhave additional benefits, e.g. if there is a riskof hydroplaning. You will only gain thesebenefits if the correct direction of rotation ismaintained.An arrow on the sidewall of the tire indicatesits correct direction of rotation.You may mount a spare wheel/emergencyspare wheel against the direction of rotation.Observe the time restriction on use as well asthe speed limit specified on the spare wheel/emergency spare wheel.

G WARNINGGasoline is highly flammable and poisonous.It burns violently and can cause seriouspersonal injury.Never allow sparks, flames or smokingmaterials near gasoline.Turn off the engine before refueling.

Whenever you are around gasoline, avoidinhaling fumes and any skin or clothingcontact.Direct skin contact with fuels and theinhalation of fuel vapors are damaging to yourhealth.

Premium-grade unleaded gasoline! To ensure the longevity and full

performance of the engine, only premium-grade unleaded gasoline may be used.

If there is no premium-grade unleadedgasoline available and regular-gradeunleaded gasoline may be used; pleaseobserve the following precautions:Ronly fill the fuel tank to half full with

regular-grade unleaded gasoline and fillthe rest with premium-grade unleadedgasoline as soon as possible.Rdo not drive at the maximum speed.Ravoid sudden acceleration.Rif the vehicle is carrying a light load, e.g.

two passengers without luggage, do notallow the engine to rev above3,000 rpm.Rif the vehicle is fully loaded or is being

operated in mountainous terrain, do notdepress the accelerator pedal furtherthan Ô of the pedal travel.

Fuel requirementsUse only premium-grade unleaded gasoline.The octane number should be at least 91.Details can be found on the gas pump. Theoctane number is the average value of theResearch Octane Number (RON) and theMotor Octane Number (MON): (RON +MON) / 2, also known as knock resistance.Reformulated gasoline (RFG) and/orunleaded gasoline with additives can be used.However, the concentration of additives inthe fuel must be less than 10%, e.g.REthanolRTAMERETBERIPARTBAFor MTBE, the concentration should notexceed 15%.The concentration of methanol in gasolineincluding other additives must not exceed 3%.Using mixtures of methanol and ethanol is notpermitted. Gasohol, a mixture of 10% ethanoland 90% unleaded gasoline, can be used.

All of these mix fuels must fulfill the fuelrequirements, e.g.:Rknock resistanceRboiling pointRvapor pressure

Additives in gasolineOne of the main problems of poor fuel qualityis the forming of deposits that are createdduring the gasoline combustion process.Mercedes-Benz recommends that you usefuel brands that have the additives.Deposits may form if you use fuels withoutadditives over a longer period of time. Thesedeposits are most likely to form on the inletvalves and in the combustion chamber.This could lead to engine problems, e.g.:Rlonger engine warm-up phaseRuneven idleRengine noiseRmisfiringRloss of powerCarbon deposits may form if the availabilityof gasoline with relevant additives isinsufficient (in certain regions). In this case,Mercedes-Benz recommends the use ofadditives that have been approved forMercedes-Benz vehicles.Consult an authorized Mercedes-Benz Centeror go to the Internet sitehttp://www.mbusa.com (USA only) for a listof approved products. Comply with theinstructions for use on the product label.Do not mix other fuel additives with fuel. Thiscauses unnecessary costs and could damagethe engine.

! Do not refuel with low-grade fuel and donot use fuel additives that are not testedand approved for Mercedes-Benz vehicles.Damage to or malfunctions of the fuelsystem may otherwise occur.

Engine oil

Please bear the following in mindThe engine oils are matched to theperformance of Mercedes-Benz engines andservice intervals. You should therefore onlyuse engine oils and oil filters that areapproved for vehicles with maintenancesystems.For a list of approved engine oils and oil filters,consult an authorized Mercedes-BenzCenter. Or visit http://www.mbusa.com(USA only).

! Never use engine oil or an oil filter of aspecification other than is necessary tofulfill the prescribed service intervals. Donot change the engine oil or oil filter inorder to achieve longer replacementintervals than those prescribed. You couldotherwise cause engine damage or damageto the exhaust gas aftertreatment.Follow the instructions in the serviceinterval display regarding the oil change.Otherwise, you may damage the engine andthe exhaust gas aftertreatment.

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

This could damage the engine.

Engine oil viscosityViscosity 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 (viscosity)classification suitable for the prevailingoutside temperatures. The following tableshows the correct SAE classification to beused. The low-temperature characteristics ofengine oils can deteriorate significantly, e.g.as a result of aging, soot and fuel deposits. Itis therefore strongly recommended that youcarry out regular oil changes using anapproved engine oil with the appropriate SAEclassification.

Refrigerant of the air-conditioningsystem

The air-conditioning system is filled withR134a refrigerant and a special PAGlubricant.

! Never use refrigerant R 12 (CFC) ormineral lubricants. Otherwise, you coulddamage the air-conditioning system.

27 Restriction: only SAE 0W-40 or SAE 5W-40 engine oils may be used.

Brake fluid

G WARNINGOver a period of time, the brake fluid absorbsmoisture from the air; this lowers its boilingpoint.If the boiling point of the brake fluid is too low,vapor pockets may form in the brake systemwhen the brakes are applied hard (e.g. whendriving downhill). This would impair brakingefficiency.You should have the brake fluid renewed atregular intervals. The brake fluid changeintervals can be found in the Service Booklet.

Only use brake fluid approved by Mercedes-Benz. Information about approved brakefluids can be obtained from any authorizedMercedes-Benz Center or on the Internet athttp://bevo.mercedes-benz.com.

Coolant

Important safety notesThe coolant is a mixture of water andantifreeze/corrosion inhibitor. It performsthe following tasks:Rcorrosion protectionRantifreeze protectionRraising the boiling pointThe engine cooling system is filled at thefactory with coolant that contains anantifreeze/corrosion inhibitor that ensuresprotection down to approximately -35 ‡(-37 †).

! Only add coolant that has been premixedwith the desired antifreeze protection.Otherwise, the engine could be damaged.Further information on coolants and onfilling can be found in the Mercedes-BenzSpecifications for Service Products, MBApproval 310.1, e.g. on the Internet athttp://bevo.mercedes-benz.com. You canalso consult an authorized Mercedes-BenzCenter.

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

If the coolant has antifreeze protection downto -35 ‡ (-37 †), the boiling point of thecoolant under operating conditions isapproximately 266 ‡ (130 †).Your vehicle has a range of aluminumcomponents. Aluminum components in theengine make it necessary to use antifreeze/corrosion inhibitor coolant that has beenspecifically formulated to protect thealuminum parts. Using other antifreeze/corrosion inhibitors without thesecharacteristics affects the service life.The coolant must be used throughout the yearin order to maintain the necessary corrosionprotection and to provide protection fromoverheating. In the Service Booklet, you canfind information on the intervals for renewal.The renewal interval is determined by thecoolant type and the engine cooling systemdesign. The renewal interval in the ServiceBooklet is only valid if the coolant is renewedor filled up with Mercedes-Benz approvedproducts. Therefore, only use MB 325.0 or326.0 anticorrosion/antifreeze or anotherMercedes-Benz approved product of thesame specification.The coolant is checked at every maintenanceinterval at an authorized Mercedes-BenzCenter.The antifreeze/corrosion inhibitorconcentration in the engine cooling systemshould:Rbe at least 50%. This will protect the engine

cooling system against freezing down toapproximately -35 ‡ (-37 † ).Rnot exceed 55% (antifreeze protection to
