2019 MERCEDES-BENZ E CLASS brakes

these 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 hours
without 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 wheelrim. There are several wire cores inthe tire beadtopreventthe tire fromchanging length onthewheelrim.
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.
Load-bearing index:the load-bearing index is acodethat containsthe maximum load-bearingcapacity of a tire.
Traction:traction isthe gripresulting from fric‐tion betweenthe tires andtheroad surface.
Wear indicator:narrowbars (treadwear bars)that are distributedoverthe tire contact surface.Ifthe tire tread is level withthe bars,thewearlimit of 1/16in (1.6 mm) has beenreached.
Distribution ofvehicle occupants:distributionofvehicle occupantsover designated seat posi‐tions in avehicle.
Maximum permissible payloadweight:nomi‐nal load and luggage load plus150 lb (68kg)multipliedbythe number of seats inthevehicle.

Mercedes-AMGvehicles:observethe notes inthe Supplement. Otherwise,you may notrecog‐nize dangers.
You can askfor informationregarding permittedwheel/tire combinations at an authorizedMercedes-Benz Center.
\nWARNINGRisk of accident duetoincor‐rect dimensions of wheels and tires
If wheels and tires ofthe wrong size areinstalled,the wheel brakes or wheel suspen‐sion components may be damaged.
Alwaysreplace wheels and tires withthosethat fulfillthe specifications ofthe original part.
Whenreplacing wheels, make suretofitthecorrect:

RModel
Whenreplacing tires, make suretoinstallthecorrect:

RManufacturer
RModel
\nWARNINGRisk of injurythroughexceed‐ingthe specified tire loadrating orthepermissible speedrating
Exceedingthe specified tire loadrating orthe permissible speedrating may leadtotiredamageandtothe tires bursting.
Therefore, only use tire types and sizesapprovedforyourvehicle model.
Observethe tire loadrating and speedratingrequiredforyourvehicle.
NOTEVehicle and tire damagethroughtire types and sizesthat havenot beenapproved
For safetyreasons, onlyuse tires, wheelsand accessories which havebeen speciallyapprovedbyMercedes-Benzforyourvehicle.
These tires are specially adaptedtothe con‐
trol systems, such as ABS, ESP®and4MATIC, and marked asfollows:
RMO = Mercedes-Benz Original
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.
Wheels and tires405

Observethefollowing when selecting, installingandreplacing tires:
ROnly use tires and wheels ofthe same type(summer tires, winter tires, MOExtendedtires) andthe same make.
ROnly install wheels ofthe same size on oneaxle (left andright).
It is only permissibletoinstall a differentwheel size intheevent of aflat tire in ordertodrivetothe specialistworkshop.
ROnly install tires ofthe correct size ontothewheels.
RVehicles with a tire pressure monitoringsystem:All installed wheels must be equip‐ped with functioning sensorsforthe tirepressure monitoring system.
RAttemperatures below 45 °F (7 °C), use win‐ter tires or all-season tires marked M+Sforall wheels.
Winter tires bearingtheMsnowflake sym‐bol in additiontothe M+S marking providethe best possible grip in wintryroad condi‐tions.
RFor M+S tires, only use tires withthe sametread.
RObservethe maximum permissible speedforthe M+S tires installed.
Ifthis is belowthevehicle's maximum speed,this must be indicatedbyan appropriatelabel inthe driver'sfield of vision.
RBreak in new tires at moderate speedsforthefirst 60 miles (100 km).
RReplacethe tires after sixyears atthe latest,regardless ofwear.
RWhenreplacing with tires that do notfea‐turerun-flatcharacteristics:vehicles withMOExtended tires are not equipped with aTIREFIT kit atthefactory.Equipthevehiclewith a TIREFIT kit afterreplacing with tiresthat do notfeaturerun-flatcharacteristics,e.g. winter tires.

\nWARNINGRisk of injurythrough differ‐ent wheel sizes
Interchangingthe front andrear wheels ifthewheels or tires havedifferent dimensionsmay severelyimpairthe drivingcharacteris‐tics.
The wheel brakes or wheel suspension com‐ponents may also be damaged.
Rotatefront andrear wheels onlyifthewheels and tires are ofthe same dimen‐sions.

Notes on brakefluid
Observethe notes on operatingfluids(→page419).
\nWARNINGRisk of an accident duetovapor pocketsforming inthe brake sys‐tem
The brakefluid constantly absorbs moisturefromthe air. This lowersthe boiling point ofthe brakefluid. Ifthe boiling point istoo low,vapor pockets mayforminthe brake systemwhenthe brakes are applied hard.
This causesthe braking effecttobeimpaired.
Havethe brakefluidrenewed atthespecified intervals.
Havethe brakefluidregularlyreplaced at aqualified specialistworkshop.Only use brakefluid approvedbyMercedes-BenzaccordingtoMB-Freigabe or MB-Approval 331.0.

Brakeswarning lamp (Can‐ada)
Thered brake systemwarning lamp is lit whilethe engine isrunning.
Possible causes are:
RThe brakeforce boosting is malfunctioning andthe brakingcharacteristics may be affected.
RThereis not enough brakefluid inthe brakefluidreservoir.
\nWARNINGRisk of accident and injuryif brakeforce boosting is malfunctioning
If brakeforce boosting is malfunctioning, increased brake pedalforce may be necessaryfor braking. The brakingcharacteristics may be impaired. The braking distance can increase in emergency braking situations.
Stop in a safe location immediately. Do not continue driving.
Consult aqualified specialistworkshop.
\nWARNINGRisk of an accident duetolow brakefluid level
Ifthe brakefluid level istoo low,the braking effect andthe brakingcharacteristics may be impaired.
Pullover andstopthevehicle safely as soon as possible, paying attentiontoroad and traffic conditions. Donot continue driving under any circumstances.
