Fu nctions of ABS (anti-lock braking sy st em)
ABS re gulates th e brake pressure in critical driv‐
ing situations: R
During braking, e.g. at maximum full-s to p
braking or insuf fi cient traction of th e tires,
th e wheels are pr ev ented from blocking.R
Ve hicle st eerability while braking is ensured.
If ABS inter ve nes when braking, yo u will fe el a
pulsing in th e brake pedal. The pulsating brake
pedal can be an indication of hazardous ro ad
conditions and can ser ve as a re minder to ta ke
ex tra care while driving.
Sy st em limitations R
ABS is active from speeds of appr ox . 5 mp h

Ve hicles with Driving Assistance Pa ck ‐
age: Evasi ve St eering Assist
Ac tive Brake Assi st can help yo u to minimize th e
ri sk of a collision with ve hicles or pedestrians or
to re duce th e ef fe cts of su ch a collision. If Ac tive Brake Assi st has de te cted a ri sk of colli‐
sion, yo u will be wa rn ed visually and acousti‐
cally.
If yo u do not re act to th e visual or acoustic wa rn ‐
ing, autonomous braking can be initiated in criti‐
cal situations.
In especially critical situations, Ac tive Brake
Assi st can initia te autonomous braking direct ly .
In th is case, th e visual and acoustic wa rn ing
occurs simultaneously with th e braking applica‐
tion.
If yo u appl y th e brake yo urself in a critical situa‐
tion or appl y th e brake during autonomous brak‐
ing, situation-dependent braking assis ta nce

maximum full-s to p braking if necessar y.
If th e autonomous braking function or th e situa‐
