WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic
situations.
In such cases, Adaptive Brake Assist may:
intervene unnecessarily
R
not intervene
R
There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
G WARNING
Adaptive Brake Assist does not react:
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
to stationary obstacles
R
when cornering
R
As a result, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
Adaptive Brake Assist aids you in braking
during hazardous situations at speeds above
4 mph (7 km/h) and uses the radar sensor
system to evaluate the traffic situation.
With the help of Adaptive Brake Assist, the
distance warning signal can detect obstacles
that are in the path of your vehicle for an
extended period of time.
Should you approach an obstacle and
Adaptive Brake Assist has detected a risk of
collision, Adaptive Brake Assist calculates the
braking force necessary to avoid a rear-end
collision. Should you apply the brakes
vigorously, Adaptive Brake Assist will
Driving safety systems
automatically increase the braking force to a
level suitable for the traffic conditions.
Keep the brake pedal depressed until the
X
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if:
you release the brake pedal
R
there is no longer any danger of a rear-end
R
collision
no obstacle is detected in front of your
R
vehicle
Adaptive Brake Assist is then deactivated.
Up to vehicle speeds of around 155 mph
(250 km/h), adaptive Brake Assist is capable
of reacting to moving objects that have
already been recognized as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due
to a malfunction in the radar sensor system,
the brake system remains available with full
brake boosting effect and BAS.
In particular, the detection of obstacles can
be impaired if there is:
dirt on the sensors or anything else
R
covering the sensors
snow or heavy rain
R
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
vehicle, have the configuration and operation
of the radar sensor 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.
