The Anti-lock Brake System (ABS) regulates the
brake pressure in critical driving situations:
During braking, for instance, at maximum full-
R

tion, the wheels are prevented from locking.
Vehicle steerability while braking is ensured.

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-
