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, detec-
tion can be impaired.
Detection by the radar sensor system is also
impaired in the event of:
dirt on the sensors or obscured sensors
R
interference by other radar sources
R
strong radar reflections, for example, in
R
multi-storey car parks
a narrow vehicle travelling in front, e.g. a
R
motorcycle
a vehicle travelling in front on a different
R
line
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.
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 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 can also detect stationary 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
you depress the accelerator pedal
R
you activate kickdown

If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS, the brake lamps flash rapidly. In
this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard
warning button (
page 113).
