Assistance through power-assisted steering if
R
it detects a swerving manoeuvre.
Activation by an abrupt steering movement
R
during a swerving manoeuvre.
Assistance during swerving and straightening
R
of the vehicle.
Reaction from a speed of approximately
R
20 km/h up to a speed of approximately
70 km/h.
You can prevent the assistance at any time by
actively steering.
& WARNING Risk of an accident despite
Evasive Steering Assist
Evasive Steering Assist cannot always clearly
identify objects and complex traffic situa‐
tions.
In addition, the steering support of Evasive
Steering Assist is generally not sufficient to
avoid a collision.
In such cases Evasive Steering Assist can:
give an unnecessary warning or provide
R
assistance
not give a warning or not provide assis‐
R
tance
Always pay careful attention to the traf‐
#
fic situation; do not rely on Evasive
Steering Assist alone.
Be ready to brake and take evasive
#
action, if necessary.
Prevent the assistance by actively steer‐
#
ing in non-critical driving situations.
Drive at an appropriate speed if pedes‐
#
trians are close to the path of your vehi‐
cle.

Driving and parking 191
The system may be impaired or may not function
in the following situations:
In snow, rain, fog, heavy spray, if there is
R
glare, in direct sunlight or in greatly varying
light conditions.
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.
For pedestrians or vehicles if they move
R
quickly into the sensor detection range.
For pedestrians who are hidden by other
R
objects.
If the typical outline of a pedestrian cannot
R
be distinguished from the background
If a pedestrian is not detected as such, e.g.
R
due to special clothing or other objects.
On bends with a tight radius.
