regulates the brake pressure in critical driv‐

R During braking, e.g. at maximum full-s top
braking or insuf ficient tyre traction, the
wheels are pr evented from lock ing.
R Vehicle steerability while braking is ensured.
If ABS inter venes 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 ser veas a reminder totake
ex tra care while driving.
