Driving sy stems and your responsibility
Yo ur vehicle is equipped with driving sy stems
which assist youin drivin g, parking and maneu‐

and do not relie ve you of your responsibility. Pay
attention tothe tra ffic conditions at all times
and inter vene when necessary . Beaware of the
limitations rega rding the safe use of these sys‐
te ms.
Fu nction of thera dar senso rs
Some driving and driving safe ty systems use
ra dar sensors tomonitor the area in front of,
behind or next totheve hicle (depending on the
ve hicle's equipment).
Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind thera diator grill. Keep these
parts free of dirt, ice and slush (
→page 336).
The sensors must not be co vered, forex ample

re flecting sticke rs.Fo llowing an impact and in th
eeve nt of associated damage , which may not
be visible, tothe bumpers or radiator grille, ha ve
th e function of thera dar sensors checked at a
qu alified specialist workshop. The driver assis‐
ta nce sy stem may no longer workproperly.
