Cleaning and care
Information onwashingthevehicle in a carwash
\nWARNINGRisk of accident duetoreduced braking effect afterwashingthevehicle
The braking effect isreduced afterwashingthevehicle.
Afterthevehicle has beenwashed,brake carefully while paying attentiontothe traffic conditions untilthe brakingeffect has been fullyrestored.
NOTEDamageduetounsuitable carwash
Before driving into a carwash makesurethatthe carwash is suitableforthevehicle dimensions.
Ensurethere is sufficient ground clear‐ance betweenthe underbody andtheguiderails ofthe carwash.
Ensurethatthe clearance width ofthecarwash, in particularthe width oftheguiderails, is sufficient.
Toavoid damageto yourvehicle when using acarwash, ensurethefollowing beforehand:
RActive Distance AssistDISTRONIC andtheHOLD function are deactivated.
Rthe 360° Camera ortherear view camera isswitched off.
Rthe side windowsand sliding sunroof arecompletelyclosed.
Rthe blowerfortheventilation/heating isswitched off.
Rthe windshield wiper switch is in positionZ.
Rin carwashes with a conveyor system: neu‐tral\\is engaged.
Rthe SmartKeyis at a minimum distance of10ft(3 m)awayfromthevehicle,otherwisethe trunk lid could open unintentionally.
Ifyouwould liketoleavethevehicle while itis beingwashed, make surethe SmartKeyis
located inthevehicle. The]gear isother‐wise automatically engaged.
If, afterthe carwash,youremovethewaxfromthe windshield and wiperrubbers,thiswill prevent smearing andreduce wipernoise.
Information on using a powerwasher
\nWARNINGRisk of accident when usinghigh-pressure cleaning equipment withround-spraynozzles
Thewater jet from around-spraynozzle (dirtgrinder) may cause damagetotires and sus‐pension componentsthat is not visible.
Components damaged inthisway mayfailunexpectedly.
Do not use high-pressurecleaningequipment withround-spraynozzlestocleanyourvehicle.
Damaged tires or suspension compo‐nents must bereplaced immediately.
Maintenance and care359

Notes on noise or unusual handlingcharac‐teristics
While driving, pay attentiontovibrations, noisesand unusual handlingcharacteristics, e.g. pullingtoone side. This may indicatethatthe wheels ortires are damaged. Ifyou suspectthat a tire isdefective,reduceyour speed immediately.Stopthevehicle as soon as possibletocheckthewheels and tiresfor damage. Hidden tire dam‐age could also be causingthe unusual handlingcharacteristics. Ifyoufind no signs of damage,havethe tires and wheelschecked at aqualifiedspecialistworkshop.
Notes onregularlyinspecting wheels andtires
\nWARNINGRisk of accident from dam‐aged tires
Damaged tires can cause tire pressure loss.
As aresult,you could lose control ofyourvehicle.
Checkthe tiresregularlyfor signs ofdamageandreplace any damaged tiresimmediately.
\nWARNINGRisk of aquaplaning duetoinsufficient tire tread
Insufficient tire tread willresult inreducedtire grip. The tire tread is no longer abletodissipatewater.
This meansthat in heavyrain or slushtherisk ofhydroplaning is increased, in particu‐lar ifvehicle speed is not adaptedtosuittheconditions.
Ifthe tire pressure istoo high ortoo low,tires mayexhibit different levels ofwear atdifferent locations onthe tire contact sur‐face.
Thus,you shouldregularlycheckthetread depth andthe condition ofthe tirecontact surface acrossthe entire widthof all tires.

Maximumweight ofthe ladenvehicle:themaximumweight isthe sum ofthe curbweightofthevehicle,theweight ofthe accessories,themaximum load andtheweight of optional equip‐ment installed atthefactory.
Kilopascal (kPa):metric unitfor tire pressure.6.9 kPa correspondsto1 psi. Another unitfortire pressureis bar.100 kilopascal (kPa) equals1 bar.
Load index:in additiontothe load-bearingindex,the load index may also be imprinted onthe sidewall ofthe tire. This specifiesthe load-bearing capacity ofthe tire more precisely.
Curbweight:theweight of avehicle withstand‐ard equipment includingthe maximum capacityof fuel, oil and coolant. It also includesthe airconditioning system and optional equipment ifthese are installed onthevehicle, but does notinclude passengers or luggage.
Maximum tire load:the maximum tire load isthe maximum permissibleweight in kilograms orlbsfor whicha tire is approved.
Maximum permissible tire pressure:maxi‐mum permissible tire pressurefor one tire.
Maximum load on one tire:maximum load onone tire. This is calculatedbydividingthe maxi‐mum axle load of one axlebytwo.
PSI (pounds per square inch):standard unit ofmeasurementfor tire pressure.
Aspectratio:ratio between tire height and tirewidth in percent.
Tirepressure:pressure insidethe tire applyingan outwardforcetoeverysquare inch ofthe tire.The tire pressure is specified in pounds persquare inch (psi), in kilopascals (kPa) or in bar.The tire pressure should only be corrected whenthe tires are cold.
Cold tire pressure:the tires are cold whenthevehicle has been parkedfor at least3 hourswithout direct sunlight onthe tires orthevehiclehas been drivenfor lessthan 1 mile (1.6 km).
Tirecontact surface:the part ofthe tirethatcomes into contact with theroad.
Tirebead:the purpose ofthe tire bead istoensurethatthe tire sits securely onthe wheel

Sidewall:the part ofthe tire betweenthe treadandthe tire bead.
Weight of optional equipment:the combinedweight ofthe optional equipmentweighing morethanthereplacedstandard parts and morethan5 lbs (2.3kg).This optional equipment, such ashigh-performance brakes, level control system, aroof luggagerackor high-performance batteries,is not included inthe curbweight andtheweightofthe accessories.
TIN (Tire IdentificationNumber):a uniqueidentification number which can be usedby atire manufacturertoidentify tires,forexample,in a productrecall, andthus identifythe pur‐chasers. The TIN is made up ofthe manufactur‐er's identity code, tire size, tire type code andthe manufacturing date.

RMOE = Mercedes-Benz Original Extended(run-flat tire onlyfor certain wheels)
RMO1 = Mercedes-Benz Original (only cer‐tain AMG tires)
Certaincharacteristics, such as handling,vehicle noise emissions, fuel consumption,etc. mayotherwise be adversely affected.Furthermore,other tire sizes couldresult inthe tiresrubbing againstthe body and axlecomponents when loaded. This couldresultin damagetothe tire orthevehicle.
Only use tires, wheels and accessoriesthathavebeenchecked andrecommendedbyMercedes-Benz.
NOTERisktodriving safety fromretrea‐ded tires
Retreaded tires are neithertested norrecom‐mendedbyMercedes-Benz, since previousdamage cannot always be detected onretreaded tires.
Forthisreason driving safety cannot be guar‐anteed.
Do not use used tires ifyou havenoinformation abouttheir previous usage.
NOTEPossible damagetowheels or tireswhen drivingover obstacles
Large wheels havea lower tire section width.The lowerthe tire section width,the greateristherisk of damagetowheels or tires whendrivingover obstacles.
Avoid obstacles or drive particularlycarefully.
NOTEDamagetoelectronic componentparts fromthe use of tire-mountingtools
Vehicles with a tire pressure monitoringsystem:Electronic component parts arelocated inthe wheel.Tire-mountingtoolsshould not be used inthe area ofthevalve.
This couldotherwise damagethe electroniccomponent parts.

NOTEDamagetosummer tires at lowambienttemperatures
Atlow ambienttemperatures,tears couldformwhen driving with summer tires, caus‐ing permanent damagetothe tires.
Attemperatures below 45 °F (7 °C),use M+S tires .
Accessory partsthat are not approvedforyourvehiclebyMercedes-Benz or are not being usedcorrectly can impairthe operating safety.
