Functions of ABS (Anti-lock Braking System)
ABS regulates the brake pressure in critical driv-
ing situations:
During braking, e.g. at maximum full-stop
R
braking or insufficient tyre traction, the wheels
are prevented from locking.
Vehicle steerability while braking is ensured.
R
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road con-
ditions and can serve as a reminder to take extra
care while driving.
System limits
ABS is active from speeds of approx. 5 km/h.
R
ABS may be impaired or may not function if a
R
malfunction has occurred and the yellow !
ABS warning lamp lights up continuously in
the instrument cluster after the engine is star-
ted.
Function of BAS
& WARNING Risk of an accident caused by a
malfunction in BAS (Brake Assist System)
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 pre-
vents the wheels from locking.
The Brake Assist System (BAS) supports your
emergency braking situation with additional brake
force.
If you depress the brake pedal quickly, BAS is
activated:
BAS automatically boosts the brake pressure.
R
BAS can shorten the braking distance.
R
ABS prevents the wheels from locking.

The brakes will function as usual once you release
the brake pedal. BAS is deactivated.
