CONTROLS
▷
▷
▷
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.
The ultrasonic sensors of the parking assis-
tance systems are located in the rear bumper.
In case of external interference with the
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

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
