BAS PLUS provides braking assistance in haz-
ardous situations with vehicles in front within a
speed range between 7 km/h and 250 km/h.
At speeds of up to approximately 70 km/h, BAS
PLUS can react to:
R
stationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
R
pedestrians in the path of your vehicle
R
obstacles crossing your path, which move in
the detection range of the sensors and are
recognised by them
i
If BAS PLUS demands particularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE
®
) are activated simulta-
neously (
Y
page 57).
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual again if:
R
you release the brake pedal
R
there is no longer a risk of collision
R
no obstacle is detected in front of your vehicle
R
you depress the accelerator pedal
R
you activate kickdown
COLLISION PREVENTION ASSIST
PLUS
General notes
i
Observe the "Important safety notes" sec-
tion (
Y
page 70).
COLLISION PREVENTION ASSIST PLUS consists
of a distance warning function with an autono-
mous braking function and Adaptive Brake
Assist.
COLLISION PREVENTION ASSIST PLUS can help
you to minimise the risk of a collision 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:
R
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 multi-
storey car parks
R
a narrow vehicle travelling in front, e.g. a
motorcycle
R
a vehicle travelling in front on a different line
R
new vehicles or after a service on the COLLI-
SION PREVENTION ASSIST PLUS system
Please observe the information in the section
on running-in the vehicle (
Y
page 157).
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions 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 igni-
tion.
You can activate or deactivate COLLISION PRE-
VENTION ASSIST PLUS in the on-board com-
puter (
Y
page 291). When deactivated, the dis-
tance warning function and the autonomous
braking function are also deactivated.
If COLLISION PREVENTION ASSIST PLUS is
deactivated, the
æ
symbol appears in the
assistance graphics display.
Distance warning function
General notes
The distance warning function can help you to
minimise the risk of a collision with the vehicle 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.
