Driving sy stems and your responsibility
Yo ur vehicle is equipped with driving sy stems
which assist youin drivin g, parking and maneu‐
ve ring theve hicle. The driving sy stems are aids
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&#39;s equipment).
Depending on theve hicle&#39;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 389). The sensors must not be co
vered, forex ample
by bicycle rack s, overhanging loads or radar-
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.

WARNING Risk of an accident despite
Evasive Steering Assist
Evasive Steering Assist cannot always clearly
identify objects and complex traf fic situa‐

In addition, thesteering support of Evasive
St eering Assist is generally not suff icientto
av oid a collision.
In such cases Evasive Steering Assist can:
Rgive an unnecessary warning or pr ovide

Rnot give awa rning or not pr ovide assis‐
ta nce
#Alw ays pay careful attention tothe traf‐

St eering Assist alone.
#Be ready tobrake and take evasive
action if necessar y.
#Preve ntthe assis tance byactively steer‐
ing in non-critical driving situations.
#Drive at an appropriate speed if pedes‐
trians are close tothe path of your vehi‐
cle.
