When driving at a speed above 30 km/h: if
you depress the brake pedal sharply, BAS
PLUS automatically increases the brake pres-
sure to a degree suited to the traffic situation.
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.
Up to a speed of approximately 70 km/h, BAS
PLUS may react to:
stationary objects in the path of your vehi-
R
cle, e.g. stopped or parked vehicles
pedestrians in the path of your vehicle
R
obstacles crossing your path, which move
R
in the detection range of the sensors and
are recognised by them
i
If BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE
ted simultaneously.
Keep the brake pedal depressed until the
X
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual, if:
you release the brake pedal
R
there is no longer a risk of collision
R
no obstacle is detected in front of your
R
vehicle
you depress the accelerator pedal
R
you activate kickdown

COLLISION PREVENTION ASSIST
PLUS
General notes
COLLISION PREVENTION ASSIST PLUS con-
sists of a distance warning function with an
autonomous 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.
Switching the sound on/off
COLLISION PREVENTION ASSIST PLUS is
activated after every ignition cycle. You can
activate or deactivate COLLISION PREVEN-
TION ASSIST PLUS in the on-board computer
(
page 287). When deactivated, the dis-
Y
tance warning function and the autonomous
®
) are activa-
braking function are also deactivated.
If COLLISION PREVENTION ASSIST PLUS is
deactivated, the æ symbol appears in the
assistance graphics display.
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
Please observe the information in the sec-
tion on running-in the vehicle
(
Y
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
page 178).
