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. Intheevent of damagetothebumpers orradiator grill, orfollowing a collisionimpactingthe bumpers orradiator grill, havethefunction oftheradar sensorschecked at aquali‐fied specialistworkshop. The driver assistancesystem 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.
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.
Mercedes‑AMGvehicles:always observethenotes inthe Supplement. Otherwise,you mayfailtorecognize dangers.
17 2Driving and parking

ESP®can monitor and improvedrivingstabilityand traction inthefollowing situations, withinphysical limits:
RWhen pullingawayon awet 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:
ROne or more wheels are braked.
RThe engine output is adapted accordingtothe situation.
ESP®is deactivated ifthe

pedestrians, orreducethe effects of sucha colli‐sion.
IfActive Brake Assisthas detected arisk of colli‐sion, awarningtone sounds andtheLdis‐tancewarning lamp lights up inthe instrumentcluster.
Ifyou do notreacttothewarning, autonomousbraking can be initiated in critical situations.
In especially critical situations,Active BrakeAssistcan initiateautonomous braking directly.Inthis case,thewarning lamp andwarningtoneoccur simultaneously with the braking applica‐tion.
Ifyou applythe brakeyourself in a critical situa‐tion or applythe brake during autonomous brak‐ing, situation-dependent braking assistanceoccurs. The brake pressure increases uptomax‐imum full-stop braking if necessary.
If autonomous braking or situation-dependentbraking assistance has occurred, display1appears inthe multifunction display andthenautomatically goes out after a short time.
Ifthe autonomous braking function orthe situa‐tion-dependent braking assistance is triggered,additional preventive measuresfor occupant
protection (PRE-SAFE®) may also be initiated.
\nWARNINGRisk 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
Always pay careful attentiontothe traf‐fic situation; do notrely onActive BrakeAssistalone.Active Brake Assistis onlyan aid. The driver isresponsibleformaintaining a suitable distancetothevehicle in front,vehicle speed andforbraking in good time.
Be preparedtobrake or swerveif nec‐essary.
Also observethe system limitations ofActiveBrake Assist.

The individual subfunctions areavailable inthefollowing speedranges:Distancewarning function
The distancewarning function issues awarninginthefollowing situations:
RFrom approximately 4mph (7 km/h), ifyourvehicle is critically closetoavehicle or
pedestrian,you will hear an intermittentwarningtone andtheLdistancewarninglamp lights up inthe instrument cluster.
