WARNING
BAS PLUS does not react:
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
R
As a result, BAS PLUS may not intervene in all
critical situations. There is a risk of an
accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In the event of snowfall or heavy rain, the
recognition can be impaired.
Recognition by the radar sensor system is
also impaired in the event of:
dirt on the sensors or anything else
R
covering the sensors
interference by other radar sources

example in parking garages
a narrow vehicle traveling in front, e.g. a

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
vehicle, have the configuration and operation
of the radar sensors checked at a qualified
specialist workshop. This also applies to
collisions 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
possible moment.
Driving safety systems
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
hazardous 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
stationary objects. Examples of stationary
objects are stopped or parked vehicles.
i
If BAS PLUS demands particularly high
braking force, preventative passenger
protection measures (PRE-SAFE
activated simultaneously.
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
function 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

®
ESP monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
®
If ESP detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP

can also stabilize the vehicle during braking.
