146 Driving and parking
Depending on the vehicle's equipment, the radar
sensors are integrated behind the bumpers
and/or behind the radiator grill. Keep these parts
free of dirt, ice and slush (
sors must not be covered, for example by bicycle
racks, overhanging loads or stickers. After a colli‐
sion, 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.

ABS controls the brake pressure in critical situa‐
tions:
The wheels are prevented from locking when
R
braking, e.g. during maximum full-stop brak‐
ing or when there is insufficient tire traction
The steerability of the vehicle in terms of
R
physical possibilities is ensured when braking
ABS is active from speeds of approx. 3 mph
R
(5 km/h). On a slippery road surface, ABS
intervenes even if you only brake gently.
System limits
If there is a malfunction and the yellow ! ABS
warning lamp lights up continuously in the instru‐
ment display after starting the engine, ABS may
be impaired or inoperative.
If ABS intervenes, you will feel a pulsing in the
brake pedal. The pulsating brake pedal may be an
indication of hazardous road conditions and func‐
tions as a reminder to take extra care while driv‐
ing.
If ABS intervenes: keep the brake pedal firmly
depressed until the braking situation has passed.
To carry out maximum full-stop braking:
depress the brake pedal with full force.
Function of BAS (Brake Assist System)
& WARNING Risk of an accident caused by
a malfunction in BAS (Brake Assist Sys‐
tem)
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased.
Depress the brake pedal with full force
#
in emergency braking situations. ABS
prevents the wheels from locking.
BAS supports you with additional braking force in
an emergency braking situation.
If you depress the brake pedal quickly, BAS is
activated:
BAS automatically boosts the braking force of
R
the brakes
BAS can shorten the braking distance
R
ABS prevents the wheels from locking
R
When you release the brake pedal, the brakes
function as usual again. BAS is deactivated.
