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, e.g. due tomaximum full-s top
braking or insuf ficient traction of the tires.
RVe hicle steerability while braking is ensured.
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.
Sy stem limitations
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
RABS may be impaired or may not function if a

RWhen pulling away on wet or slippe ryroads.
RWhen braking.
RIn stro ng sidewinds when you are driving
fast erthan 50 mph (80 km/h).
ESP
®can stabilize theve hicle byinter vening in
th efo llowing ways:
ROne or more wheels are braked.
RThe engine output is adap ted according to
th e situation.
ESP
