When the camera field of view is covered,
for instance by a fogged up windshield or
labels.
Top view cameras
▷
▷
▷
▷
If the camera lens is dirty or damaged.
With exterior mirrors folded in.
With open doors or open cargo area.
When driving toward bright lights or strong
reflections, e.g., because of a setting sun.
▷
▷
When it is dark outside.
The camera has overheated due to exces-
sive temperatures and temporarily turned
off.
One exterior mirror camera is located at the
bottom of each exterior mirror housing.
▷
During calibration of the camera immedi-
ately after vehicle delivery.
Rearview camera
If applicable, a Check Control message will be
displayed when the system limits are reached.
Radar sensors
Safety information
Warning
The rearview camera is located in the handle
strip on the rear of the vehicle.
The vehicle radar sensors and thus also the
driver assistance systems can be impaired by
external influences, e.g., interference. There
is a risk of accident. Watch the surrounding
traffic situation closely, be ready to take over
steering and braking at any time, and actively
intervene where appropriate.
Functional requirement of the
cameras
The areas of the cameras are clean and clear.
Additional information:
▷
▷
Washing the vehicle, refer to page 316.
Vehicle care, refer to page 317.
System limits of the cameras
The function of the cameras can be limited or
may indicate something wrong, for instance in
the following situations:
▷
▷
In heavy fog, wet conditions, or snowfall.
On steep hills, in steep depressions or in
tight curves.

If sensors are covered such as by labels,
films or a license-plate carrier.
Front radar sensor
If the sensor is not aligned correctly, for in-
stance due to parking damage.
If the radiation range of the sensors is cov-
ered, e.g., by protruding cargo.
When the field of view of the sensors is cov-
ered, e.g., by garage walls, hedges, snow
hills, vehicles or trailers.

After improper paint work on the vehicle in
the area of the sensors.
The front radar sensor is located in the front
bumper.
On steep hilltops or in sharp dips in the
road.
If applicable, a Check Control message will be
displayed when the system limits are reached.

ultrasonics, for instance from passing ve-
hicles, loud machines or other ultrasonic
sources.
Ultrasonic sensors, side
▷
▷
Under certain weather conditions, e.g., high
moisture, wet conditions, snowfall, cold, ex-
treme heat, or strong wind.
With tow bars and trailer hitches of other
vehicles.
▷
▷
▷
With thin or wedge-shaped objects.
With moving objects.
With elevated, protruding objects such as
ledges.
The ultrasonic sensors of the parking assis-
tance systems are located on the side in the
front and rear bumpers.
▷
▷
With objects with corners, edges, and
smooth surfaces.
In the case of objects with fine surfaces or
structures, e.g., wire mesh fences.
Functional requirement of the
ultrasonic sensors
The areas of the ultrasonic sensors are clean
and clear.
▷
▷
For objects with porous surfaces.
With small and low objects, for instance
boxes.
Additional information:
▷
▷
Low objects already displayed, for instance
curbs, can be outside of the detection
ranges of the sensors.
▷
▷
Washing the vehicle, refer to page 316.
Vehicle care, refer to page 317.
With soft obstacles or obstacles covered in
foam material.
System limits of the ultrasonic
sensors
The detection of objects with ultrasonic meas-
urements can run into physical limits, e.g., in
the following situations:
▷
▷
▷
With plants and bushes.
In automatic car washes.
In the event of uneven floors, e.g. speed
