Vehicles with side collision warning
If there is no response to the steering wheel vi‐
brating and a lane marking is crossed at speeds
of up to 210 km/h, 130 mph, the system re‐
sponds if necessary with a brief active steering
intervention. The steering intervention helps to
return the vehicle to its lane. Steering interven‐
tion can be felt at the steering wheel, and can be
overridden manually at any time.
Flashing of light
A flashing light when the vehicle is unlocked indi‐
cates that the system is performing a self-test.

Safety note
WARNING
The system may not respond at all, or may re‐
spond too late, incorrectly or without justifica‐
tion due to system limitations. There is a risk of
accident or material damage. Observe the in‐
formation on the system limits and intervene
actively if necessary.
Upper speed limit
The system is temporarily disabled at speeds
over approx. 250 km/h, 155 mph.
At speeds below approx. 250 km/h, 155 mph,
the system once again responds according to
the setting.
System limits of the sensors
For further information:
▷ Radar sensors, see page 48.
▷ For vehicles with side-collision warning: cam‐
eras, see page 47.
Functional limitations
The system may have limited functionality in the
following situations, for example:
▷ If the speed of the approaching vehicle is sig‐
nificantly higher than the driver's own speed.
▷ On sharp bends or narrow roads.
▷ If the bumper is dirty, iced up or covered,
for example by stickers.
In vehicles with side collision warning, the steer‐
ing intervention may be limited in the following
situations, for example:
▷ When there are missing, worn, poorly visible,
merging/separating or ambiguous lane mark‐
ings; for example, in areas where there are
roadworks.
▷ If lane markings are covered by snow, ice, dirt
or water.
▷ If lane markings are not white.
▷ If lane markings are obscured by objects.
▷ If the vehicle is too close to the vehicle ahead.
▷ If the camera is impaired.
▷ Up to 10 seconds after starting the engine
using the Start/Stop button.
A Check Control message is displayed in the
event of limited functionality.
The system cannot be switched on when the
trailer socket is in use, for example when operat‐
ing with a trailer or bicycle carrier. A Check Con‐
trol message is shown.
Warning displays
Depending on the selected setting for warnings,
for example the warning time, it is possible that
more or fewer warnings will be displayed. As a
result, there may also be an increased number of
premature warnings about critical situations.
Side collision warning
Principle
The system helps to avoid potential side colli‐
sions.
