Ultrasonic sensors, side

The ultrasound sensors of the Automatic Parking
Assistant are located on the side of the vehicle.
System limits of the ultrasonic
sensors
The detection of objects with ultrasonic measurements
can run into physical limits, e.g., in the
following situations:
- In case of dirty sensors.
- In case of covered sensors, such as due to labels.
- If the sensor is not aligned correctly, for instance
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 instance
jacket.
- In case of external interference of the ultrasound,
for instance from passing vehicles,
loud machines or other ultrasonic sources.
- Under certain weather conditions, e.g., high
relative atmospheric humidity, wet conditions,
snowfall, cold, extreme heat, or strong wind.
- With tow bars and trailer couplings 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.
- With objects with a fine surface structure
such as fences.
- For objects with porous surfaces.
- With small and low objects, for instance
boxes.
- With soft obstacles or obstacles covered in
foam material.
- With plants and bushes.
- In automatic car washes.
- On uneven surfaces, such as speed bumps.
- Due to heavy exhaust.
- Cargo that extends beyond the perimeter of
the vehicle is not taken into account by the
ultrasonic sensors.
- When the trailer hitch cover is not on straight.
If applicable, a Check Control message will be
displayed when the system limits are reached.
