R
a narrow vehicle travelling in front, e.g. a
motorcycle
R
a vehicle travelling in front on a different
line
R
vehicles quickly moving into the radar sen-
sor 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 cov-
ered
R
glare on the camera system, e.g. from the
sun being low in the sky
R
darkness
R
if:
-
pedestrians move quickly, e.g. into the
path of the vehicle
-
the camera system no longer recognises
a pedestrian as a person due to special
clothing or other objects
-
a pedestrian is concealed by other
objects
-
the typical outline of a person is not dis-
tinguishable from the background
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper-
ation checked at a qualified specialist work-
shop. This also applies to collisions at slow
speeds where there is no visible damage to
the front of the vehicle.
Following damage to the windscreen, have
the configuration and operation of the cam-
era system 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 under 30 km/h:
if you depress the brake pedal, BAS PLUS is
activated. Braking assistance from BAS PLUS
is carried out at the last possible moment.
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.
At speeds of up to approximately 70 km/h,
BAS PLUS reacts to:
R
stationary objects in the path of your vehi-
cle, e.g. stopped or parked vehicles
R
pedestrians in the path of your vehicle
R
objects crossing your path
i
If BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE
®
) are activa-
ted simultaneously.
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
