Driving sy stems and your responsibility
Yo ur vehicle is equipped with driving sy stems
which assist youin drivin g, parking and maneu‐
ve ring theve hicle. The driving sy stems are aids
and do not relie ve you of your responsibility. Pay
attention tothe tra ffic conditions at all times
and inter vene when necessary . Beaware of the
limitations rega rding the safe use of these sys‐
te ms.
Fu nction of thera dar senso rs
Some driving and driving safe ty systems use
ra dar sensors tomonitor the area in front of,
behind or next totheve hicle (depending on the
ve hicle's equipment).
Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind thera diator grill. Keep these
parts free of dirt, ice and slush (
→page 336).
The sensors must not be co vered, forex ample
by bicycle rack s, overhanging loads or radar-
re flecting sticke rs.Fo llowing an impact and in th
eeve nt of associated damage , which may not
be visible, tothe bumpers or radiator grille, ha ve
th e function of thera dar sensors checked at a
qu alified specialist workshop. The driver assis‐
ta nce sy stem may no longer workproperly.

Functions of ABS (anti-lock braking sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, e.g. at maximum full-s top
braking or insuf ficient traction of the tires,
th e wheels are pr evented from blocking.
16 6
Driving and pa rking
RVehicle steerability while braking is ensured.
If ABS inter venes when braking, youwill feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can ser veas a reminder totake
ex tra care while driving.
Sy stem limitations
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
RABS may be impaired or may not function if a
malfunction has occur red and theye l‐

WARNING Risk of an accident caused by
a malfunction in BAS (Brake Assist Sys‐
te m)
If BA S is malfunctioning, the braking dis tance
in an emergency braking situation is
increased.
#Depre ssthe brake pedal with full forc e
in emer gency braking situations. ABS
pr eve nts the wheels from locking.
BA S suppo rts yo ur eme rgency braking situation
with additional brake forc e.
If yo u depress the brake pedal quickl y,BA S is
acti vated:
RBA S au tomatical lyboosts the brake pres‐
sure.
RBA S can short enthe braking dis tance.
RABS pr events the wheels from locking.
The brakes will function as usual once you
re lease the brake pedal. BAS is deactivated.
Functions of ESP®(Electronic Stability Pro‐
gr am)

WARNING Risk of skidding if ESP®is
malfunctioning
If ESP
®is malfunctioning, ESP®cannot car ry
out vehicle stabilization. In addition, other
driving saf etysy stems are switched off.
#Drive on carefull y.
#Have ESP®checked at a qualified spe‐
cialist workshop.

WARNING Risk of skidding if ESP®is
deactivated
If yo u deactivate ESP

out vehicle stabilization.
#ESP®should only be deactivated in the
fo llowing situations.
ESP®monitors and impr oves driving stability and
