Driving and driving safety systems
Driving systems andyourresponsibility
Yourvehicle is equipped with driving systemswhich assistyou in driving, parking and maneu‐veringthevehicle. The driving systems are aidsand do notrelieveyou ofyourresponsibility per‐tainingtoroad traffic law.Pay attentiontothetraffic conditions at all times and intervenewhen necessary. Beaware ofthe limitationsregardingthe safe use ofthese systems.
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 409).The sensors must not be covered,forexamplebycycleracks,overhanging loads,stickers,foilorfoilstoprotect againststonechipping. Intheevent of damagetothe bumpers orradiator grill,orfollowing a collision impactingthe bumpers orradiator grill, havethe function oftheradar sen‐sorschecked at aqualified specialistworkshop.The driver assistance system may no longerworkproperly.

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.
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)
&WARNINGRisk 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)
&WARNINGRisk 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.
&WARNINGRisk of skidding if ESP®isdeactivated
Ifyou deactivate ESP®, ESP®cannot carryoutvehiclestabilization.
#ESP®should onlybe deactivated inthefollowing situations.
Mercedes‑AMGvehicles:observethe notes inthe Supplement. Otherwise,you may notrecog‐nize dangers.
ESP®can monitor and improvedrivingstabilityand traction inthefollowing situations, withinphysical limits:
RWhen pullingawayonwet or slipperyroad‐way.
RWhen braking.
RInstrong side winds whenyou are drivingfasterthan 50mph (80 km/h).
Ifthevehicle deviates fromthe direction desired
bythe driver, ESP®canstabilizethevehiclebyintervening inthefollowingways:

RThevehicle isstabilizedbymeans of individ‐ual brake application on one side.
Function of EBD (electronic brakeforce dis‐tribution)
EBD ischaracterizedbythefollowing:
RMonitoring andregulatingthe brake pressureontherear wheels.
RImproved drivingstability when braking,especially on bends.
Function ofSTEER CONTROL
STEER CONTROL helpsyoubytransmitting anoticeablesteeringforcetothesteering wheel inthe directionrequiredforvehiclestabilization.

&WARNINGRisk of an accident causedbylimited detection performance ofActiveBrake Assist
Active Brake Assistcannot alwaysclearlyidentify objects and complex traffic situa‐tions.
In suchcases,Active Brake Assistmight:
RGive awarning or brake withoutreason
RNotgive awarning or not brake
