Operating safety
\nWARNINGRisk of accident duetomal‐functions or systemfailures
Ifyou do not havethe prescribed service/maintenanceworkor anyrequiredrepairscarried out,this couldresult in malfunctionsor systemfailures.
Always havethe prescribed service/maintenanceworkaswell anyrequiredrepairs carried out at aqualified spe‐cialistworkshop.
\nWARNINGRisk of accident or injuryduetoincorrect modifications on electroniccomponent parts
Modification of electronic components,theirsoftware or wiring could impairtheir function
and/orthe function ofother networked com‐ponent parts. In particular, systemsrelevanttosafety could also be affected.
As aresult,these may no longer functionproperlyand/or jeopardizethe operatingsafety ofthevehicle.
Nevertamper withthe wiring and elec‐tronic component parts ortheir soft‐ware.
You should haveallworkon electricaland electronic components carried outat aqualified specialistworkshop.
Observethe "On-board electronics" section in"Technical data".
\nWARNINGRisk offireduetoflammablematerials on hot parts oftheexhaustsystem
Flammable material such as leaves, grass ortwigs may ignite iftheycome into contactwithhot parts oftheexhaust system.
When driving on unpavedroads or off-road,regularlycheckthevehicle under‐side.
Removetrapped plants orotherflam‐mable material.
Ifthere is damage, consult aqualifiedspecialistworkshop immediately.
NOTEDamagetothevehicle
Inthefollowing situations, in particular,thereis arisk of damagetothevehicle:
RThevehicle becomes grounded, e.g. on ahigh curb or an unpavedroad
RThevehicle is driventoofastover anobstacle, e.g. a curb, speed bumpor pot‐hole
RA heavy objectstrikesthe underbody orchassis components
In situations such asthis,the body,theunderbody,chassis components, wheels ortires could be damaged withoutthe damagebeing visible. Components damaged inthis
24General notes

ROnly increasethe engine speed gradually andacceleratethevehicletofull speed after1,000 miles (1,500 km).
This also applies whenthe engine or parts ofthedrivetrain havebeenreplaced.
Please also observethefollowing breaking-innotes:
RIn certain driving and driving safety systems,the sensors adjust automatically while a cer‐tain distance is being driven afterthevehiclehas been delivered or afterrepairs.Full sys‐tem effectiveness is notreached untiltheend ofthisteach-in process.
RBrakepads, brake discs and tiresthat areeither new or havebeenreplaced only ach‐ieveoptimum braking effect and grip afterseveral hundred kilometers of driving. Com‐pensateforthereduced braking effectbyapplyinggreaterforcetothe brake pedal.
Notes on driving
\nWARNINGRisk of accident duetoobjects inthe driver'sfootwell
Objects inthe driver'sfootwell may impedepedal travel or block a depressed pedal.
This jeopardizesthe operating androadsafety ofthevehicle.
Stowall objects inthevehicle securelysothattheycannotgetintothe driver'sfootwell.
Always installthefloor mats securelyand as prescribed in ordertoensurethatthere is always sufficientroomforthe pedals.
Do not use loosefloor mats and do notplacefloor mats ontop of one another.
\nWARNINGRisk of accident duetounsuitablefootwear
Operation ofthe pedals may berestrictedduetounsuitablefootwear such as:
RShoes with platformsoles
RShoes with high heels
RSlippers
When driving alwayswear suitableshoes in ordertobe abletooperatethepedals safely.
\nWARNINGRisk of accident when switch‐ing offthe ignition when driving
Ifyou switchoffthe ignition while driving,safety functions arerestricted or no longeravailable. This may affectthe powersteeringsystem andthe brakeforce boosting,forexample.
You willthen needtouse considerably moreforcetosteer and brake.

Havethe transmissionchecked at aqualified specialistworkshop immediately.
Function ofthe 4MATIC
4MATIC ensuresthat allfour wheels are driven
when needed.Together with ESP®and 4ETS,4MATIC improvesthe traction ofyourvehiclewhenever a driven wheel spins duetoinsuffi‐cient traction.
Ifyoufailtoadaptyour drivingstyle, 4MATIC canneitherreducetherisk of an accident norover‐ridethe lawsof physics. 4MATIC cannottakeaccount ofroad,weather and traffic conditions.4MATIC is only an aid.You areresponsible espe‐ciallyfor maintaining a safe distance fromthevehicle in front,forvehicle speed,for braking ingood time andforstaying in lane.
In wintryroad conditions,the maximumeffect of 4MATIC can be achieved only ifyou
use winter tires (M+S tires), with snowchains if necessary.
Refueling
Refuelingthevehicle
\nWARNINGRisk offireorexplosion fromfuel
Fuels are highlyflammable.
Fire, openflames, smoking and creationof sparksmust beavoided.
Switchoffthe ignition and, ifavailable,thestationary heater, before and whilerefuelingthevehicle.
\nWARNINGRisk of injuryfrom fuels
Fuels are poisonous and hazardousto yourhealth.
Do not swallow fuel or let it come intocontact with skin,eyes or clothing.
Do not inhale fuelvapor.
Keepchildrenawayfrom fuel.
Keep doors and windowsclosed duringtherefueling process.
Ifyou orother people come into contact withfuel, observethefollowing:

Settingthevehicle level
\nWARNINGRisk of accident becausevehicle level istoo high
Ifyou drive at a highervehicle level,the driv‐ingcharacteristics may be impaired duetothe highervehicle center of gravity.
Thevehicle can drift outwards,forexample,whensteering or cornering.
Alwayschoose avehicle level which issuitedtothe drivingstyle andtheroadsurface conditions.
\nWARNINGRisk of entrapment fromvehi‐cle lowering
When loweringthevehicle, people couldbecome trapped iftheir limbs are betweenthevehicle body andthe tires or underneaththevehicle.
Make sure no one is underneaththevehicle or inthe immediate vicinity ofthe wheel arches whenyou lowerthevehicle.
\nWARNINGRisk of entrapment fromvehi‐cle lowering
Vehicles with AIRMATIC or level control:Whenyou unload luggage or leavethevehi‐cle,thevehiclefirstrises slightly andthenreturnstothe set level shortly afterwards.
You or anyone else inthe vicinity ofthewheel arches orthe underbody couldthusbecome trapped.
Thevehicle can also be lowered after beinglocked.
