Driving and driving safety systems
Note on driving systems and your responsibil‐
ity
Your vehicle is equipped with driving systems
which assist you in driving, parking and manoeu‐
vring the vehicle. The driving systems are aids
and do not relieve you of your responsibility.
Always pay attention to the traffic and intervene
if necessary. Be aware of the limitations regard‐
ing the safe use of these systems.
Information about sensors
Certain driving and driving safety systems use
sensors
1
to monitor the area in front of, behind
or next to the vehicle (depending on the vehicle's
equipment).
Depending on the vehicle's equipment, the radar
sensors are integrated behind the bumpers
and/or behind the radiator grille. Keep these
parts free of dirt, ice and slush (
/
page 288).
The sensors must not be covered, for example by
bicycle racks, overhanging loads or stickers. After
a collision, have the function of the radar sensors
checked at a qualified specialist workshop as
damage (both visible or non-visible) may have
occurred to the bumper or radiator trim.

Functions of ABS (Anti-lock Braking System)
Observe the important safety guidelines for the
driving safety system.
ABS controls the brake pressure in critical situa‐
tions:
R
the wheels are prevented from locking when
braking, e.g. during maximum full-stop brak‐
ing or when there is insufficient tyre traction
R
the steerability of the vehicle in terms of
physical possibilities is ensured when braking
R
ABS is active from speeds of approx. 5 km/h.
On a slippery road surface, ABS intervenes
even if you only brake gently.
