In such cases, BAS PLUS may:
intervene unnecessarily
R
not intervene
R
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
WARNING
G
BAS PLUS does not react:
to small people, e.g. children
R
to animals
R
to oncoming vehicles
R
when cornering
R
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:
there is dirt on the sensors or anything else
R
covering the sensors
there is interference by other radar sources
R
there are strong radar reflections, for
R
example in parking garages
a narrow vehicle traveling in front, e.g. a
R
motorbike
a vehicle traveling in front on a different line
R
vehicles quickly moving into the radar sen-
R
sor system detection range
Recognition by the camera system is also
impaired in the event of:
dirt on the camera or if the camera is cov-
R
ered
there is glare on the camera system, e.g.
R
from the sun being low in the sky
darkness
R
if:
R
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
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 configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low 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
system checked at a qualified specialist work-
shop.
Function
To avoid a collision, BAS PLUS calculates the
brake force necessary if:
you approach an obstacle, and
R
BAS PLUS has detected a risk of collision
R
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
pressure will be carried out at the last possi-
ble 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 traf-
fic 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).
