R
cle, e.g. stopped or parked vehicles
pedestrians in the path of your vehicle
R
objects crossing your path and that are

recognized in the detection range of the
sensors

braking force, preventative passenger pro-
tection measures (PRE-SAFE

COLLISION PREVENTION ASSIST
PLUS
General information
COLLISION PREVENTION ASSIST PLUS con-
sists of a distance warning function with an
autonomous emergency braking function and
adaptive Brake Assist.
COLLISION PREVENTION ASSIST PLUS can
help you to minimize the risk of a front-end
collision with a vehicle ahead 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

be impaired if:
there is dirt on the sensors or anything else

Observe the notes in the section on break-
ing-in (
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 low speeds where there is no visible
damage to the front of the vehicle.

The distance warning function does not react:
to people or animals
R
to oncoming vehicles
R
to crossing traffic

Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
