\nWARNINGRisk of burns and poisoningduetothe anti-glare mirror electrolyte
Electrolyte may escape iftheglass in anautomatic anti-glare mirror breaks.
The electrolyte is harmful and causes irrita‐tion. It mustnot come into contact withyourskin,eyes,respiratory organs or clothing orbe swallowed.
Ifyou come into contact with electro‐lyte, observethefollowing:RRinsethe electrolyte fromyour skinand seek medical attention immedi‐ately.
RIf electrolyte comes into contactwithyoureyes,rinsethemthor‐oughly with cleanwater and seekmedical attention immediately.
RIfthe electrolyte is swallowed,immediatelyrinseyour mouth outthoroughly. Do not inducevomiting.Seek medical attention immediately.
RImmediatelychange out of clothingwhich has come into contact withelectrolyte.
RIf an allergicreaction occurs, seekmedical attention immediately.
The insiderearview mirror andthe outside mir‐ror onthe driver's side automatically go intoanti-glare mode if light from a headlamp hitsthesensor onthe insiderearview mirror.

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.

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.

You 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 isgenerally not 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.
System limitationsFull system performance is notavailablefor afew seconds after switching onthe ignition orafter driving off.
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 are impaired duetointerfer‐ence fromotherradar sources, e.g.strongradarreflections in parkinggarages.
RIf a loss of tire pressure or a defective tirehas been detected and displayed.
RIn complex traffic situations whereobjectscannotalways be clearly identified.
RIf pedestrians orvehicles movequickly intothe sensor detectionrange.
RIf pedestrians are hiddenby other objects.
RIfthe typical outline of a pedestrian cannotbe distinguished fromthe background.
RIf a pedestrian is not detected as such, e.g.duetospecial clothing orother objects.
ROn bends with a tightradius.

doing so,you will make use ofthe engine's brak‐ing effect. Thisrelievesthe load onthe brakesystem and preventsthe brakes fromoverheat‐ing andwearingtooquickly.
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.
