Sensors of the vehicle
CONTROLS
▷
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., 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 badge
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, injury, or property dam-
age. 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 340.
Vehicle care, refer to page 341.
System limits of the cameras
The cameras may not work properly, e.g.,
show something that is incorrect, in the follow-
ing situations:
▷
▷
In heavy fog, wet conditions, or snowfall.
On steep hills, in steep depressions or in
tight curves.

System limits of the radar sensors
The function of the radar sensors may be re-
stricted or not available, for instance in the fol-
lowing situations:
The front radar sensor is located in the front
bumper.

In case of dirty sensors.
Radar sensors, side, front
In case of iced-up sensors.
If sensors are covered such as by labels,
films or a license-plate carrier.
▷
▷
▷
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.
The radar sensors are located on the side of
the front bumper.
▷
▷
After improper paint work on the vehicle in
the area of the sensors.
On steep hilltops or in sharp dips in the
road.
Radar sensors, side, rear
If applicable, a Check Control message will be
displayed when the system limits are reached.
The radar sensors are located on the side of
the rear bumper.

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:
The ultrasonic sensors of the parking assis-
tance systems are located in the front bumper.
▷
▷
▷
If the sensors are dirty or covered, e.g., by
stickers.
Ultrasonic sensors, rear
If the sensor is not aligned correctly, for in-
stance due to parking damage.
After improper paint work on the vehicle in
the area of the sensors.
▷
▷
For small children and animals.
For persons with certain clothing, for in-
stance jacket.
▷
▷
With obstacles and persons at the edge of
the lane.
In case of external interference with the
ultrasonics, for instance from passing ve-
hicles, loud machines or other ultrasonic
sources.
The ultrasonic sensors of the parking assis-
tance systems are located in the rear bumper.
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.
▷
With objects with corners, edges, and
smooth surfaces.

Sensors of the vehicle
CONTROLS
▷
In the case of objects with fine surfaces or
structures, e.g., wire mesh fences.
▷
▷
For objects with porous surfaces.
With small and low objects, for instance
boxes.
▷
▷
Low objects already displayed, for instance
curbs, can be outside of the detection
ranges of the sensors.

In the event of uneven floors, e.g. speed
bumps.
▷
▷
If there are large amounts of exhaust gas.
Cargo that extends beyond the perimeter of
the vehicle is not taken into account by the
ultrasonic sensors.
If applicable, a Check Control message will be
displayed when the system limits are reached.
