System limits
Limits of ultrasonic measurement
The detection of objects can reach the physical
limits of ultrasonic measurement, e.g.:
▷ With tow bars and trailer hitches.
▷ With thin or wedge-shaped objects.
▷ With low objects.
▷ With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷ In heavy rain.
▷ When sensors are very dirty or covered in
ice.
▷ When sensors are covered in snow.
▷ On rough road surfaces.
▷ In large buildings with right angles and
smooth walls, e.g., in underground garages.
▷ In heavy exhaust.
▷ Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Malfunction
A Check Control message is displayed.
The range of the sensors is shown as a shaded
area on the Control Display.
PDC has failed. Have the system checked.
To ensure full operability:
▷ Keep the sensors clean and free of ice.
▷ When using high-pressure washers, do not
spray the sensors for long periods and main‐
tain a distance of at least 12 in/30 cm.
Surround View
The concept
Surround View comprises various camera as‐
sistance systems that help the driver when park‐
ing, maneuvering, and at complex exits and in‐
tersections.
▷ Backup camera, refer to page 126
▷ Side View, refer to page 130.
▷ Top View, refer to page 129.Backup camera
The concept
The backup camera provides assistance in park‐
ing and maneuvering backwards. The area be‐
hind the vehicle is shown on the Control Display.Notes
Check the traffic situation as well
Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside the picture area of the backup camera.◀At a glance
