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 oftheradar sensors
Some driving and driving safety systems useradar sensorstomonitorthe area in front of,behind or nexttothevehicle (depending onthevehicle's equipment).
Depending onthevehicle's equipment,theradarsensors are integrated behindthe bumpersand/or behindthe Mercedesstar.Keeptheseparts free of dirt, ice and slush(page 364). The sensors must not be cov‐ered,forexamplebycycleracks,overhangingloads,stickers,foil orfoilstoprotect againststonechipping.

Function of ABS (Anti-lock Braking System)
ABSregulatesthe brake pressure in critical driv‐ing situations:
RDuring braking, e.g. at full brake applicationor insufficient tire traction,the wheels areprevented from locking.
RVehiclesteerability while braking is ensured.
Driving and parking171

If ABS intervenes when braking,you willfeel apulsing inthe brake pedal. The pulsating brakepedal can be an indication of hazardousroadconditions and can serveas aremindertotakeextra care while driving.
System limitationsRABS is active from speeds of approx. 5mph(8 km/h).
RABS may be impaired or may not function if amalfunction has occurred andtheyel‐low%ABSwarning lamp lights up contin‐uously inthe instrument cluster aftertheengine isstarted.
Function ofBAS (Brake Assist System)
\nWARNINGRisk of an accident causedbya malfunction inBAS (Brake AssistSys‐tem)
IfBAS is malfunctioning,the braking distancein an emergency braking situation isincreased.
Depressthe brake pedal with fullforcein emergency braking situations. ABSpreventsthe wheels from locking.
BAS supportsyour emergency braking situationwith additional brakeforce.
Ifyou depressthe brake pedalquickly,BAS isactivated:
RBAS automaticallybooststhe brake pres‐sure.
RBAS can shortenthe braking distance.
RABS preventsthe wheels from locking.
The brakes will function as usual onceyoureleasethe brake pedal.BAS is deactivated.
Function of ESP®(ElectronicStability Pro‐gram)
\nWARNINGRisk of skidding if ESP®ismalfunctioning
If ESP®is malfunctioning, ESP®cannot carryoutvehiclestabilization. In addition,otherdriving safety systems are switched off.
Drive on carefully.
HaveESP®checked at aqualified spe‐cialistworkshop.
\nWARNINGRisk of skidding if ESP®isdeactivated
Ifyou deactivate ESP®, ESP®cannot carryoutvehiclestabilization.
ESP®should onlybe deactivated inthefollowing situations.
