R
a narrow vehicle is traveling in front, e.g. a
motorbike
R
a vehicle is traveling in front on a different line
R
vehicles quickly move into the radar sensor
system detection range
Recognition by the camera system is also
impaired in the event of:
R
dirt on the camera or if the camera is covered
R
glare on the camera system, e.g. from the sun
being low in the sky
R
darkness
R
or if:
-
pedestrians move quickly, e.g. into the path
of the vehicle
-
the camera system no longer recognizes a
pedestrian as a person due to special cloth-
ing or other objects
-
a pedestrian is concealed by other objects
-
the typical outline of a person is not distin-
guishable from the background
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensors 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.
Following damage to the windshield, have the
configuration and operation of the camera sys-
tem checked at a qualified specialist workshop.
Function
To avoid a collision, BAS PLUS calculates the
brake force necessary if:
R
you approach an obstacle, and
R
BAS PLUS has detected a risk of collision
When driving at a speed
under20 mph(30 km/h): if you depress the
brake pedal, BAS PLUS is activated. The
increase in brake pressure will be carried out at
the last possible moment.
When driving at a speed
above20 mph(30 km/h): if you depress the
brake pedal sharply, BAS PLUS automatically
raises the brake pressure to a value adapted to
the traffic situation.
BAS PLUS provides braking assistance in haz-
ardous situations with vehicles in front within a
speed range between 4 mph (7 km/h) and
155 mph (250 km/h).
At speeds of up to approximately 44 mph
(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
recognized 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, 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 vehi-
cle.
R
you depress the accelerator pedal.
R
you activate kickdown.
COLLISION PREVENTION ASSIST
PLUS
General information
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 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.
