Limits of ultrasonic measurement
Ultrasonic measurements might not function in
the following situations:
For small children and animals.
For persons with certain clothing, e.g.,
coats.
With external interference of the ultra‐
sound, e.g., from passing vehicles or loud
machines.
When sensors are dirty, iced over, dam‐
aged or out of position.
Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme 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 or cargo.
With objects with corners and sharp edges.
With objects with a fine surface structure
such as fences.
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.
False warnings
The system may issue a warning under the fol‐
lowing conditions even though there is no ob‐
stacle within the detection range:
In heavy rain.
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.
In large buildings with right angles and
smooth walls, for instance in underground
garages.
In automatic vehicle washes.
Due to heavy exhaust.
Due to other ultrasound sources, for in‐
stance sweeping machines, high pressure
steam cleaners or neon lights.
The malfunction is signaled by a continuous
tone alternating between the front and rear
speakers.
As soon as the malfunction due to other ultra‐
sound sources is no longer present, the sys‐
tem is again fully functional.
If necessary, switch off automatic PDC activa‐
tion on obstacle detection, for instance in vehi‐
cle washes, to reduce false alarms.
Malfunction
A Check Control message is displayed.
PDC has failed. Have the system checked by a
dealer’s service center or another qualified
service center or repair shop.
Rearview camera
Concept
The rearview camera provides assistance in
parking and maneuvering backwards. The area
behind the vehicle is shown on the Control
Display.
Safety information
WARNING
The system does not relieve from the
personal responsibility to correctly assess the
traffic situation. There is a risk of an accident.
Adjust the driving style to the traffic condi‐
tions. Watch traffic and vehicle surroundings
