Observe the information on the system limits
and intervene actively if necessary.
Detection range
The detection ability of the system is limited.
Only objects detected by the system are taken
into account.
For this reason, the system may fail to respond
or only respond after a delay.
For example it is possible that the following may
not be detected:
▷ Slow-moving vehicle when approaching it at
high speed.
▷ Vehicles suddenly cutting in or braking heav‐
ily.
▷ Vehicles with an unusual rear appearance.
▷ Two-wheeled vehicles ahead.
Upper speed limit
The system is temporarily disabled at speeds
over approx. 250 km/h, 155 mph. Once the
speed drops back below this threshold, the sys‐
tem becomes responsive again according to its
settings.
Functional limitations
The system may have limited functionality in the
following situations, for example:
▷ In thick fog, wet conditions or snow.
▷ On sharp bends.
▷ When Driving Stability Control Systems are
limited or deactivated, for example DSC OFF.
▷ If the field of view of the camera or the wind‐
screen in front of the rear-view mirror is soiled
or covered.
▷ If the camera has overheated due to exces‐
sively high temperatures and has been tem‐
porarily deactivated.
▷ Depending on the equipment version: if the
radar sensors are soiled or covered.
▷ After work performed incorrectly on the vehi‐
cle paintwork near to the radar sensors.
▷ Up to 10 seconds after starting the engine
using the start/stop button.
▷ During the camera calibration process imme‐
diately after vehicle delivery.
▷ If there is sustained glare due to oncoming
light, for example if the sun is low in the sky.
Attaching any objects, for example stickers or
decals, in the area of the radar beam will also im‐
pair radar sensor operation and may even cause
them to fail.
Sensitivity of the warnings
The higher the sensitivity of the warning settings,
for example warning time, the more warnings are
displayed. As a result, there may be an increased
number of premature or unjustified warnings and
responses.
Avoidance assistant
Principle
The system supports the driver in certain situa‐
tions when there is a need to avoid something,
for example people or obstacles that appear sud‐
denly.
General
The system issues warnings and intervenes to
provide support if there is a possibility to perform
an evasive manoeuvre to the side. Sensors mon‐
itor and detect the space around the vehicle. The
system then utilises the detected free space to
