WARNING
BAS PLUS does not react:
R
to small people, e.g. children
R
to animals
R
to oncoming vehicles
R
when cornering
As a result, BAS PLUS may not intervene in all
critical situations. There is a risk of an acci-
dent.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In the event of snowfall or heavy rain, the rec-
ognition can be impaired.
Recognition by the radar sensor system is also
impaired in the event of:
R
there is dirt on the sensors or anything else
covering the sensors
R
there is interference by other radar sources
R
there are strong radar reflections, for exam-
ple in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different line
R
vehicles quickly moving 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
there is 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 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 under 20 mph
(30 km/h): if you depress the brake pedal, BAS
PLUS is activated. The increase in brake pres-
sure will be carried out at the last possible
moment.
When driving at a speed above 20 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 59).
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 vehi-
cle.
R
you depress the accelerator pedal.
R
you activate kickdown.
