Function of ABS
The Anti-lock Brake System (ABS) regulates the
brake pressure in critical driving situations:
During braking, e.g. at full brake application
R
or insufficient tire 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
conditions and can serve as a reminder to take
extra care while driving.
System limits
ABS is active from speeds of approx. 5 mph
R
(8 km/h).
ABS may be impaired or may not function if a
R
malfunction has occurred and the yel‐
low ! ABS warning lamp lights up contin‐
uously in the instrument cluster after the
engine is started.
