Fu nctions of ABS (anti-lock braking sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, the wheels are pr evented
from blocking, forex ample due tomaximum
full-s top braking or insuf ficient traction of the
tires.
RVe hicle steerability while braking is ensured.
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
If ABS inter venes when braking, youwill 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.
