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 brake
pedal 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.
16 6Driving and parking

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.
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

Canceling a brake application ofActive BrakeAssist
You can cancel a brake application ofActiveBrake Assistat any timeby:
RDepressingthe accelerator pedal fully.
RReleasingthe brake pedal.
Active Brake Assistmay cancelthe brake appli‐cation when one ofthefollowing conditions isfulfilled:
RYou maneuverto avoidthe obstacle.
RThereis no longer arisk of collision.
RAn obstacle is no longer detected in front ofyourvehicle.
EvasiveSteering Assist (onlyvehicles withDriving AssistancePackage)
EvasiveSteering Assist hasthefollowingcharac‐teristics:
RCan detectstationary or crossing pedes‐trians.
RCan assistthe driver with additionalsteeringassistance if it detects a swerving maneuver.
RCan be activatedbyan abruptsteering move‐ment during a swerving maneuver.
RCan assist during swerving andstraighteningofthevehicle.
RCanreact from a speed of approximately12mph (20 km/h) uptoa speed of approx‐imately 43mph (70 km/h).
RYou can preventthe assistance at any timebyactivelysteering.

\nWARNINGRisk of an accident despiteEvasiveSteering Assist
EvasiveSteering Assist cannotalways clearlyidentify objects and complex traffic situa‐tions.
In addition,thesteering support of EvasiveSteering Assist isgenerallynot sufficienttoavoid a collision.
In such cases EvasiveSteering Assist can:
Rgive an unnecessarywarning or provideassistance
Rnot giveawarning or not provide assis‐tance
Always pay careful attentiontothe traf‐fic situation; do notrely on EvasiveSteering Assist alone.
Bereadytobrake andtakeevasiveaction if necessary.
Preventthe assistancebyactivelysteer‐ing in non-critical driving situations.
Drive at an appropriate speed if pedes‐trians are closetothe path ofyourvehi‐cle.
Also observethe system limitations of EvasiveSteering Assist.
System limitations
The system may be impaired or may not functioninthefollowing situations:
RIn snow,rain,fog, heavy spray, ifthere isglare, in direct sunlight or ingreatlyvaryingambient light.
RIfthe sensors are dirty,fogged up, damagedor covered.
RIfthe sensors malfunction dueto otherradarsource interference,forexamplestrongradarreflections in parkinggarages.
RIf a loss of tire pressure or a defective tirehas been detected and displayed.
The system may notreact correctly:
RIn complextraffic situations whereobjectscannotalways be clearly identified.
RTopedestrians orvehicles iftheymovequickly intothe sensor detectionrange.
RTopedestrians who are hiddenby otherobjects.
RIfthe typical outline of a pedestrian cannotbe distinguished fromthe background.
RIf a pedestrian is notrecognized as such, e.g.duetospecial clothing orother objects.
ROn bends with a tightradius.

Do not use cruise control inthefollowing situa‐tions:
RIn traffic situations whichrequire frequentchanges of speed, e.g. in heavy traffic, onwindingroads.
ROn slipperyroads.Accelerating can causethe drive wheelstolose traction andthevehicle couldthen skid.
RIfyou are driving when visibility is poor.
Operating cruise control
\nWARNINGRisk of accident duetostoredspeed
Ifyou call upthestored speed andthis islowerthanyour current speed,thevehicledecelerates.
Takeinto accountthe traffic situationbefore calling upthestored speed.
Requirements:RESP®must be activated, but not intervening.
RThe driven speed is at least15mph(20 km/h).
RThe transmission is in position[.
Toactivate cruise control:pressrockerswitch1up.

Active Distance Assist DISTRONIC
Function ofActive Distance AssistDISTRONIC
Active Distance AssistDISTRONIC maintainstheset speed on free-flowingroads. Ifvehicles infront are detected,the set distance is main‐tained, if necessary,untilthevehicle comesto ahalt. Thevehicle accelerates or brakes depend‐ing onthe distancetothevehicle in front andthe set speed. The speed and distancetothevehicle in front are set and saved onthesteeringwheel onvehicles withoutthe Driving AssistancePackage, intherange between15mph(20 km/h) and120mph (200 km/h) and, on
vehicles withthe Driving AssistancePackage, intherange between15mph (20 km/h) and130mph (210km/h).
Otherfeatures ofActive Distance AssistDISTRONIC:
RAdjuststhe drivingstyle depending ontheselected drive program (fuel-saving, comfort‐able or dynamic) (→page148)
