of damage to property. Actively intervene as
warranted. Refer to the information in this Own‐
er’s Manual regarding the scope of the sys‐
tem’s operation and limitations.
Trailer towing
With a trailer, a trailer power socket in use or
when trailer towing is activated, the rear PDC
functions will be switched off.
White symbol is displayed.
Depending on the vehicle equipment,
the range of the sensors is shown as a
shaded area on the Control Display.
Limits of ultrasonic measurement
The detection of objects with ultrasonic meas‐
urements can run into physical limits, e.g., in the
following situations:
▷ For small children and animals.
▷ For persons with certain clothing, for instance
coats.
▷ With external interference of the ultrasound,
for instance from passing vehicles or loud
machines.
▷ When sensors are dirty, iced over, damaged
or out of position.
▷ Under certain weather conditions, e.g., high
relative 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 obstacles and persons at the edge of
the lane.
▷ With soft obstacles or obstacles covered in
foam material.
▷ With plants and bushes.
▷ Low objects already displayed, for instance
curbs, can move into the blind area of the
sensors before or after a continuous tone
sounds.
▷ Cargo that extends beyond the perimeter of
the vehicle is not taken into account by the
system.
False warnings
The system may issue a warning under the fol‐
lowing conditions even though there is no obsta‐
cle 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 ga‐
rages.
▷ In automatic vehicle washes.
▷ Due to heavy exhaust.
▷ When the trailer hitch cover is not on straight.
▷ Due to other ultrasound sources, for instance
sweeping machines, high pressure steam
cleaners or neon lights.
To prevent false alarms, switch off automatic
PDC activation on obstacle detection, for in‐
stance in automatic vehicle washes.
