System limits of the sensors
Additional information:
▷ Radar sensors, refer to page 38.
▷ On vehicles with side collision warning: cam‐
eras, refer to page 37.
Functional limitations
The system may be limited in the following situa‐
tions:
▷ When a vehicle is approaching at a speed
much faster than your own.
▷ In tight curves or on narrow roads.
▷ The bumper is dirty, iced up or covered,
for instance by stickers.
For vehicles with side collision mitigation, the
steering intervention can be limited, for instance
in the following situation:
▷ In the event of missing, worn, poorly visible,
merging, diverging, or multiple lane markings
such as in construction areas.
▷ With lane boundaries that are covered in
snow, ice, dirt or water.
▷ With lane boundaries that are not white.
▷ With lane boundaries that are covered by ob‐
jects.
▷ When driving very close to the vehicle in front
of you.
▷ If the camera is impaired.
▷ Up to 10 seconds after the start of the engine
via the Start/Stop button.
A Check Control message is displayed when the
system is not fully functional.
If the trailer power socket is occupied or trailer
towing is activated, for instance during operation
with trailer or bicycle rack, the system cannot be
switched on. A Check Control message is dis‐
played.
Displaying warnings
Depending on the selected warning settings,
e.g., warning time, more or fewer warnings can
be displayed. However, there may also be an ex‐
cess of premature warnings of critical situations.
Side collision mitigation
Principle
The side collision warning helps to avoid immi‐
nent side collisions.
General information
Radar sensors monitor the space next to the ve‐
hicle when traveling faster than a minimum
speed of up to approx. 130 mph/210 km/h.
The minimum speed is country-specific and is
displayed in the menu for the intelligent Safety
systems.
The front camera determines the lane marking
positions.
If, for instance, another vehicle is detected next
to the vehicle and if there is a risk of collision with
this vehicle, the system helps avoid the collision.
For this purpose, the system issues a warning
with a blinking LED in the exterior mirror and a vi‐
brating steering wheel. If necessary, the system
will carry out an active steering intervention.
