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.
14 8Driving and parking

Do not switch offthe ignition while driv‐ing.
\nDANGERRisk offatal injuries duetoexhaustgases
Combustion engines emit poisonousexhaustgases such as carbon monoxide. Inhalingtheseexhaustgases is hazardoustohealthand can leadtopoisoning.
Never leavethe enginerunning in anenclosed space without sufficientventi‐lation.
\nWARNINGRisk of skidding and of anaccident duetoshifting down on slipperyroad surfaces
Ifyou shift down on slipperyroad surfacestoincreasethe engine braking effect,the drivewheels may lose traction.
Do not shift down on slipperyroad sur‐facestoincreasethe engine brakingeffect.
\nDANGERRisk offatal injury duetopoi‐sonousexhaustgases
Ifthetailpipe is blocked or sufficientventila‐tion is not possible, poisonousexhaustgasessuch as carbon monoxide may enterthevehi‐cle. This isthe case ifthevehiclegetsstuckin snow,forexample.
Keepthetailpipe andthe area aroundthevehicle free from snow whentheengine orthestationary heater arerun‐ning.
Open a window onthe windward side ofthevehicletoensure an adequate sup‐ply of fresh air.
\nWARNINGRisk of accident and injuryduetobeing underthe influence of alco‐hol and drugs while driving
Driving when underthe influence of alcoholand/or drugs is anextremelydangerouscombination. Even smallquantities of alcoholor drugs may affectyourreflexes, perceptionand judgment.
The probability of a serious orevenfatal acci‐dent greatly increases ifyou drive whenunderthe influence of alcohol or drugs.
Do not drink alcohol ortakedrugs whiledriving, and do not allow anyonetodrive who has been drinking alcohol ortaking drugs.
\nWARNINGRisk of accident duetothebrake systemoverheating
Ifyou leaveyourfootonthe brake pedalwhen driving,the brake system mayover‐heat.
This increasesthe braking distance andthebrake system mayevenfail.
Never usethe brake pedal as afootrest.
Do not depressthe brake pedal andtheaccelerator pedal atthe same timewhile driving.

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.

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.
