System limits
Limits of ultrasonic measurement
The detection of objects can reach the physi‐
cal limits of ultrasonic measurement, e.g., in
the following circumstances:
▷ For small children and animals.
▷ For persons with certain clothing, e.g.
coats.
▷ If there is an external disturbance of the ul‐
trasound, e.g. from passing vehicles or
loud machines.
▷ When sensors are soiled, iced over or dam‐
aged.
▷ Under certain weather conditions, e.g.,
high relative humidity, rain, snowfall 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 or cargo.
▷ With objects with corners and sharp edges.
▷ With objects with a fine surface structure,
such as fences.
▷ For objects with porous surfaces.
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
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.
▷ On uneven surfaces, such as speed
bumps.
▷ In large buildings with right angles and
smooth walls, e.g., in underground ga‐
rages.
▷ In heavy exhaust.
▷ Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
The malfunction is signaled by a continu‐
ous tone alternating between the front and
rear speakers. As soon as the malfunction
due to other ultrasound sources is no lon‐
ger present, the system is again fully func‐
tional.
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
maintain 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
parking, maneuvering, and at complex exits
and intersections.
▷ Rearview camera, refer to page 133
▷ Side View, refer to page 135.
▷ Top View, refer to page 136.
