Cancelling a brake application of Active Brake
Assist
You can cancel a brake application of Active
Brake Assist at any time by:
Fully depressing the accelerator pedal or with
R
kickdown.
Releasing the brake pedal.
R
Active Brake Assist may cancel the brake applica‐
tion when one of the following conditions is fulfil‐
led:
You manoeuvre to avoid the obstacle.
R
There is no longer a risk of collision.
R
An obstacle is no longer detected in front of
R
your vehicle.
System limits
Full system performance is not available for a few
seconds after switching on the ignition or after
driving off.
The system may be impaired or may not function
in the following situations:
In snow, rain, fog or heavy spray.
R
If the sensors are dirty, misted up, damaged
R
or covered.
If the sensors are impaired due to interfer‐
R
ence from other radar sources, e.g. strong
radar reflections in multi-storey car parks.
If a loss of tyre pressure or a defective tyre
R
has been detected and displayed.
In complex traffic situations where objects
R
cannot always be clearly identified.
If pedestrians or vehicles move quickly into
R
the sensor detection range.
If pedestrians are hidden by other objects.
R
If the typical outline of a pedestrian cannot be
R
distinguished from the background.
If a pedestrian is not detected as such, e.g.
R
due to special clothing or other objects.
In bends with a narrow radius.
R
Following damage to the front end of the vehicle,
have the configuration and operation of the radar
sensor checked at a qualified specialist work‐
shop. This also applies to collisions at slow
speeds where there is no visible damage to the
front end of the vehicle.
