Maximum acceleration:depressthe accel‐erator pedal beyondthe pressure point.
The automatic transmission shifts uptothe nextgear whenthe maximum engine speed isreachedtoprotectthe engine fromoverrevving.
Glide mode function
Mercedes-AMGvehicles:observethe notes inthe Supplement. Otherwise,you mayfailtorec‐ognize dangers.
Withan anticipatory drivingstyle,glide modehelpsyoutoreduce fuel consumption.
Glide mode ischaracterizedbythefollowing:
Rthe combustion engine is disconnected fromthe drivetrain andthe engine continuestorun in neutral.
Rthe transmission position[is displayed ingreen inthe multifunction display.
Rvehicles with a 48 V on-board electricalsystem (EQ Boosttechnology):the com‐bustion engine is switched off depending onthe driving situation. All ofthevehicle func‐tionsremain active.
Glide mode is activated ifthefollowing condi‐tions are met:
Rdrive program;is selected.
Rthe speed is within a suitablerange.
Rtheroad's course is suitable, e.g. nosteepuphill or downhill inclines or tight bends.
Ryou are no longer depressingthe acceleratoror brake pedal.
Glide mode can also be activated ifyou haveselectedthe "Eco" settingforthe drive inthedrive program=.
Glide mode is deactivated again if one oftheconditions is no longer met.
Glide mode can also be preventedbythefollow‐ing parameters:

Tirepressure
Notes on tire pressure
\nWARNINGRisk of accident duetoinsuf‐ficient orexcessive tire pressure
Underinflated oroverinflated tires posethefollowingrisks:
RThe tires may burst, especially astheload andvehicle speed increase.
RThe tires maywearexcessively and/orunevenly,which maygreatlyimpair tiretraction.
RThe drivingcharacteristics, aswell assteering and braking, may be greatlyimpaired.
Comply withtherecommended tirepressure andcheckthe tire pressure ofall tires includingthe spare wheelregu‐larly:
Rat least once a month
Rwhenthe loadchanges
Rbefore embarking on a longer journey
Rif operating conditionschange, e.g. off-road driving
Adjustthe tire pressure as necessary.
Driving withtire pressurethat istoo high ortoolow can:
RShortenthe service life ofthe tires.
RCause increased tire damage.
RAdversely affect drivingcharacteristics andthus driving safety,e.g. dueto hydroplaning.
\nWARNINGRisk of an accident duetoinsufficient tire pressure
Tires with pressurethat istoo low canover‐heat and burstas aresult.
In addition,theyalso suffer fromexcessiveand/or irregularwear, which can significantlyimpairthe braking properties andthe han‐dlingcharacteristics.
Avoidexcessively low tire pressures inallthe tires, includingthe spare wheel.
Tirepressure which istoo low can cause:
RTiredefects as aresult ofoverheating
RImpaired handlingcharacteristics
RIrregularwear
RIncreased fuel consumption
\nWARNINGRisk of accident fromexces‐sive tire pressure
Tires withexcessively high pressure canburstbecausetheyare damaged more easilybyhighwayfill, pot holesetc.
In addition,theyalso suffer from irregularwear, which can significantly impairthe brak‐ing properties andthe handlingcharacteris‐tics.
Avoidexcessively high tire pressures inallthe tires, includingthe spare wheel.
Excessively high tire pressure canresult in:
RIncreased braking distance
RImpaired handlingcharacteristics
RIrregularwear

Changing a wheel
Notes on selecting, installing andreplacingtires
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.

NOTEDamagecausedbythe wrong fuel
Even small amounts ofthe wrong fuel couldresult in damagetothe fuel system,theengine andthe emission control system.
Onlyrefuel with low-sulfur unleadedfuel.
This fuel may contain upto10%ethanolbyvolume.Yourvehicle is suitablefor use withE10 fuel.
Neverrefuel with one ofthefollowing fuels:
RDiesel
RGasoline with morethan10%ethanolbyvolume, e.g. E15, E85, E100
RGasoline with morethan 3% methanolbyvolume, e.g. M15, M30, M85, M100
RGasoline with additives containing metal
Ifyou haveaccidentallyrefueled withthewrong fuel:
Do not switchonthe ignition.
Consult aqualified specialistworkshop.
Iftheavailable fuel is not sufficiently low in sul‐fur,this can produce unpleasant odors.
Onlyrefuel with fuelthat has at leastthe octanenumber specified inthe instruction label inthefuelfillerflap (→page154).
Ifyouwant maximum engine output:onlyrefuel with unleaded premium gradegasolinewith an octane number of at least91AKI/95RON.
As atemporary measure, iftherecommendedfuel is notavailable,you may alsorefuel withunleadedregulargasoline with at least87AKI/91RON. This mayreduce engine performanceand increase fuel consumption.
Neverrefuel usinggasoline with aneven lowerRON.
