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.
