Rsuspension and climate control settings
Rcustomizations such as interior lighting
Ifyourvehicle is accordingly equipped,you canconnectyour smartphone or another mobile enddevicetothevehicle.You can controlthisbymeans ofthe control elements integrated inthevehicle. Images and audio fromthe smartphonecan be output viathe multimedia system. Cer‐tain information is simultaneously transferredtoyour smartphone.

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.

\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.
