Fuel
Notes on fuelgradesforvehicles with agas‐oline engineObservethe notes on operatingfluids(page 425).
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 (page159).
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 output andincrease fuel consumption.
Neverrefuel usinggasoline with aneven lowerRON.

NOTEPrematurewear causedbyunlea‐dedregulargasoline
Unleadedregulargasoline can causetheenginetowear morequickly and impair lon‐gevity and performance.
If unleaded premium gradegasoline isunavailable andyou havetorefuel usingunleadedregulargasoline:
Onlyfillthe fueltanktohalf full withunleadedregulargasoline andrefill assoon as possible with unleaded pre‐miumgradegasoline.
Do not drive atthe maximum speed.

Only add cleaning additivesrecommen‐dedbyMercedes-Benztothe fuel.
Mercedes-Benzrecommendsthatyou use fuelbrandsthat haveadditives.
In some countries,the fuelavailable may nothavesufficient additives.Residue could build upinthe fuel injection system as aresult. Inthiscase, in consultation with an authorizedMercedes-Benz Center,the fuel may be mixedwiththe cleaning additiverecommendedbyMercedes-Benz.

Notes on brakefluid
Observethe notes on operatingfluids(page 425).
\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.

If antifreeze comes into contact withhotcomponent parts inthe engine compart‐ment, it may ignite.
Allowthe enginetocool down beforeadding antifreeze.
Makesurethat no antifreeze spills outnexttothefiller opening.
Thoroughly clean off any antifreezefrom component parts beforestartingthevehicle.
