False warnings
The system may issue a warning under the fol‐
lowing conditions even though there is no ob‐
stacle within the detection range:
Safety information
WARNING
▷
▷
In heavy rain.
The system can react incorrectly or not
at all due to the system limits. There is a risk of
accidents or risk of property damage. Observe
the information regarding the system limits
and actively intervene, if needed.◀
When sensors are very dirty or covered
with ice.
▷
▷
▷
When sensors are covered in snow.
On rough road surfaces.
On uneven surfaces, such as speed
bumps.
Limits of ultrasonic measurement
Ultrasonic measurements might not function in
the following situations:
▷
In large buildings with right angles and
smooth walls, e.g., in underground ga‐
rages.
▷
▷
For small children and animals.
For persons with certain clothing, e.g.,
coats.
▷
▷
▷
In automatic vehicle washes.
Due to heavy exhaust.
▷
With external interference of the ultra‐
sound, e.g., from passing vehicles or loud
machines.
Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
▷
▷
When sensors are dirty, iced over, dam‐
aged or out of position.
If necessary, switch off automatic PDC activa‐
tion on obstacle detection, e.g., in vehicle
washes, to reduce false alarms.
Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme heat or strong wind.
Malfunction
A Check Control message is displayed.
▷
With tow bars and trailer couplings of other
vehicles.
The range of the sensors is shown as a shaded
area on the Control Display.
▷
▷
▷
With thin or wedge-shaped objects.
With moving objects.
PDC has failed. Have the system checked.
With elevated, protruding objects such as
ledges or cargo.
Surround View
▷
▷
With objects with corners and sharp edges.
With objects with a fine surface structure
such as fences.
Concept
Surround View comprises various camera as‐
sistance systems that help the driver when
parking, maneuvering, and at complex exits
and intersections.
▷
▷
▷
For objects with porous surfaces.
If cargo protrudes.
Low objects already displayed, e.g., curbs,
can move into the blind area of the sensors
before or after a continuous tone sounds.
