#Keepchildrenawayfrom fuel.
#Keep doors and windowsclosed duringtherefueling process.
Ifyou orother people come into contact withfuel, observethefollowing:
#Immediatelyrinse fuel offyour skin withsoap andwater.
#If fuel comes into contact withyoureyes, immediatelyrinsethemthor‐oughly with cleanwater.Seek medicalattention immediately.
#Ifyou swallow fuel, seek medical atten‐tion immediately.Do not inducevomit‐ing.
#Change immediately out of clothingthathas come into contact withfuel.
&WARNINGRisk offireorexplosion fromelectrostaticcharge
Electrostaticchargecan createsparksandthereby ignite fuelvapors.
#Beforeyou openthe fuelfiller cap ortakehold ofthe pump nozzle,touchthemetallicvehicle body.This discharges any electrostaticchargethat may havebuilt up.
#Do notget intothevehicle again duringtherefueling process.Otherwise, electrostaticchargecouldbuild up again.
*NOTEDamagecausedbythe wrong fuel
Vehicles with agasoline engine:
Even small amounts ofthe wrong fuel couldresult in damagetothe fuel system,theengine andthe emission control system.
#TheRONrequirement is located inthefuelfillerflap.
#Only refuel with low-sulfur unleadedfuel.
This fuel may contain upto10%ethanol.Yourvehicle is suitablefor use with E10 fuel.
Neverrefuel using any 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 accidentallyrefuel withthe wrong fuel:
#Do not switchthe ignition on.
#Consult aqualified specialistworkshop.
*NOTEDo not use dieseltorefuelvehi‐cles with agasoline engine.
Ifyou accidentallyrefuel withthe wrong fuel:
RDo not switchthe ignition on. Otherwisefuel can enterthe engine.
Even small amounts ofthe wrong fuelcouldresult in damagetothe fuel systemandthe engine. Therepair costs are high.
#Consult aqualified specialistworkshop.

Opening/closingthe hood
&WARNINGRisk of accident ifthe enginehood is unlatched while driving
An unlocked engine hood may open up whenthevehicle is in motion and blockyour view.
#Never unlatchthe engine hood whiledriving.
#Beforeevery trip, ensurethattheengine hood is latched.
&WARNINGRisk of accident and injurywhen opening and closingthe enginehood
When opening or closingthe engine hood, itmay suddenly drop intothe end position.
There is arisk of injuryfor anyone intheengine hood'srange of movement.
#Only open or closethe engine hoodwhenthere are no persons intheengine hood'srange of movement.
&WARNINGDanger of burns when open‐ingthe hood
Ifyou openthe hood whenthe engine hasoverheated or during afireinthe enginecompartment,you could come into contactwith hotgases orother escaping operatingfluids.
#Before openingthe hood, allowtheenginetocool down.
#Intheevent of afireinthe engine com‐partment,keepthe hood closed andcallthefireservice.
&WARNINGRisk of injuryduetomovingparts
Certain components inthe engine compart‐ment may continuetomoveor suddenlymoveagaineven afterthe ignition has beenswitched off, e.g.the coolerfan.
Makesure ofthefollowing before performingtasks inthe engine compartment:
#Switchthe ignition off.
#Nevertouchthe danger zone surround‐ing moving component parts, e.g.therotation area ofthefan.
#Removejewelry andwatches.
#Keep items of clothing and hairawayfrom moving parts.
&WARNINGRisk of injuryfromtouchingcomponent parts undervoltage
The ignition system andthe fuel injectionsystemworkunder highvoltage. Ifyoutouchcomponent parts which are undervoltage,you couldreceivean electric shock.
#Nevertouch component parts oftheignition system orthe fuel injection sys‐tem whenthe ignition is switched on.
&WARNINGRisk of burns from hot com‐ponent parts inthe engine compartment
Certain components inthe engine compart‐ment can beveryhot, e.g.the engine,theradiator and parts oftheexhaust system.
Maintenance and care397

&WARNINGRisk of accident causedbyrepeated drop in tire pressure
Ifthe tire pressure dropsrepeatedly,thewheel,valve or tire may be damaged.
Insufficient tire pressure can causethe tirestoburst.
#Inspectthe tirefor signs offoreignobjects.
#Check whetherthe wheel orvalve has aleak.
#Ifyou are unabletorectifythe damage,contact aqualified specialistworkshop.
You canfind information on tire pressureforthevehicle'sfactory-installed tires onthefollowinglabels:
RTireand Loading Information placard ontheB‑pillar ofyourvehicle (→page442).
RTirepressuretable onthe inside ofthe fuelfillerflap (→page 437).
Observethe maximum tire pressure(→page448).
Use a suitable tire pressuregaugetocheckthetire pressure. The outer appearance of a tiredoes not permit anyreliable conclusion aboutthe tire pressure.
Vehicles with a tire pressure monitoring sys‐tem:You can alsocheckthe tire pressure usingthe on-board computer.
Only correct tire pressure whenthe tires arecold. Conditionsfor cold tires:
RThevehicle has been parked withthe tiresout of direct sunlightfor at leastthree hours.
RThevehicle has traveled lessthan 1 mile(1.6 km).
Arise inthe tiretemperature of18°F (10 °C)increasesthe tire pressurebyapprox.10kPa(0.1 bar/1.5 psi).Takethis into account whencheckingthe tire pressure ofwarmtires.
The tire pressure recommendedfor increasedload/speed inthe tire pressuretable can affecttheride comfort.
&WARNINGRisk of accident from unsuita‐ble accessories onthe tirevalves
Ifyou mount unsuitable accessories ontotirevalves,the tirevalves may beoverloaded andmalfunction, which can cause tire pressureloss.Tirepressure monitoring systemsforretrofitting will causethe tirevalvetoremainopen. This can alsoresult in tire pressureloss.
#Only screwstandardvalve caps orvalvecaps specifically approvedbyMercedes-Benzforyourvehicle ontothe tirevalve.

#Onlyfillthe fueltanktohalf full withunleadedregulargasoline andtop up assoon as possible with unleaded pre‐mium gradegasoline.
#Do not drive atthe maximum speed.
#Avoid sudden acceleration and enginespeedsover 3000rpm.
This mayreduce engine performance andincrease fuel consumption. Neverrefuel usinggasoline with a lower octane number.
