with the vehicle in front or reduce the effects
of such a collision.
If COLLISION PREVENTION ASSIST PLUS
detects that there is a risk of a collision, you
will be warned visually and acoustically. If you
do not react to the visual and audible collision
warning, autonomous braking can be initiated
in critical situations. If you apply the brake
yourself in a critical situation, the COLLISION
PREVENTION ASSIST PLUS Adaptive Brake
Assist assists you.
Important safety notes
In particular, the detection of obstacles can
be impaired in the case of:
dirt on the sensors or obscured sensors
R
snow or heavy rain
R
interference by other radar sources
R
strong radar reflections, for example, in
R
multi-storey car parks
a narrow vehicle travelling in front, e.g. a
R
motorcycle
a vehicle travelling in front on a different
R
line
new vehicles or after a service on the COL-
R
LISION PREVENTION ASSIST PLUS system
Observe the important safety notes in the
"Running-in notes" section (
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle.

Distance warning function
General notes
The distance warning function can help you to
minimise the risk of a collision with the vehi-
cle in front or reduce the effects of such a
collision. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically.
