Certain driving and driving safety systems use
sensors 1 to monitor the area in front of, behind
or next to the vehicle (depending on the vehicle's
equipment).
Depending on the vehicle's equipment, the radar
sensors are integrated behind the bumpers
and/or behind the radiator grill. Keep these parts
free of dirt, ice and slush (

sors must not be covered, for example by bicycle
racks, overhanging loads or stickers. After a colli‐
sion, have the function of the radar sensors
checked at a qualified specialist workshop as
damage (both visible or non-visible) may have
occurred to the bumper or radiator trim.

System limitations
If there is a malfunction and the yellow ! ABS
warning lamp lights up continuously in the instru‐
ment display after starting the engine, ABS may

ABS is active from speeds of approx. 3 mph
(5 km/h). On a slippery road surface, ABS
intervenes even if you only brake gently.
