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
relative to the center of your vehicle
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.
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).
At speeds of up to approximately 40 mph
(70 km/h), BAS PLUS can also react to sta-
tionary objects. Examples of stationary
objects are stopped or parked vehicles.

If BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE

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 again, 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.
If you have activated DSR (
PLUS is likewise deactivated.
