R
a vehicle travelling in front on a different
line
R
new vehicles or after a service on the COL-
LISION PREVENTION ASSIST PLUS system
Observe the important safety notes in the
"Running-in notes" section (
Y
page 156).
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.
Activating/deactivating
The COLLISION PREVENTION ASSIST PLUS is
automatically active after switching on the
ignition.
You can activate or deactivate COLLISION
PREVENTION ASSIST PLUS in the on-board
computer (
Y
page 249). When deactivated,
the distance warning function and the auton-
omous braking function are also deactivated.
Vehicles with black and white multifunc-
tion display: when COLLISION PREVENTION
ASSIST PLUS is activated, the multifunction
display in the status overview shows the
Ä
symbol.
Vehicles with colour multifunction dis-
play: when COLLISION PREVENTION ASSIST
PLUS is deactivated, the multifunction dis-
play in the assistance graphic shows the
æ
symbol.
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.
Important safety notes
i
Observe the "Important safety notes" sec-
tion for driving safety systems (
Y
page 69).
G
WARNING
The distance warning function does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
G
WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
R
give an unnecessary warning
R
not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation; do not rely on the distance warning
function alone.
Function
The distance warning function issues a warn-
ing at speeds:
R
of approximately 30 km/h or more, if, over
several seconds, the distance maintained
to the vehicle travelling in front is insuffi-
cient. The
·
distance warning lamp
then lights up in the instrument cluster.
R
of approximately 7 km/h or more, if you
rapidly approach a vehicle in front. An inter-
mittent warning tone will then sound, and
the
·
distance warning lamp will light
up in the instrument cluster.
