re ga rding the safe use of these sy stems. Information on
radar and ultrasonic senso rsSome driving and driving sa
fety sy stems use
ra dar or ultrasonic sensors tomonitor the area in front of, behind or next
totheve hicle (depend‐
ing on theve hicle's equipment).
Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind thera diator grille. The ultrasonic
sensors are located in the front and rear bump‐
ers. Keep these parts free of dirt, ice and slush
(/ page 531). The sensors must not be cov‐
ered, forex ample bybicycle rack s, ove rhanging
loads, sticke rs,fo il or foils toprotect against

can li kewise impair the function of the ultrasonic
sensors. In theev ent of damage tothe bumpers
or radiator grille, or following a collision impact‐

cialist workshop. If the sensors are damaged,

nction of ABS The Anti-lock Brake Sy
stem (ABS) regulates the
brake pressure in critical driving situations:
R During braking, e.g. at full brake application
or insuf ficient tyre traction, the wheels are
pr eve nted from lo cking.
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.
