Limits of side protection
The system only detects standing obstacles
that entered the area of the sensors previously
when driving by.
The system detects if your vehicle is ap‐
proaching the standing obstacle due to its own
motion or steering angle.
The system does not detect whether an obsta‐
cle moves. For this reason, at standstill, the
markings are shown in the display in gray after
a certain time.

Information
WARNING
The system can react incorrectly or not
at all due to the system limits. There is risk of
accidents or risk of property damage. Observe
the system limits and actively interfere if
needed.◀
Limits of ultrasonic measurement
Ultrasonic measuring might not function under
the following circumstances:
▷ For small children and animals.
▷ For persons with certain clothing, for ex‐
ample coats.
▷ With external interference of the ultra‐
sound, for example 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, for example,
curbs, can move into the blind area of the sen‐
sors 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
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 example, in underground
garages.
▷ In automatic car washes.
▷ Through heavy pollution.
▷ Due to other ultrasound sources, for exam‐
ple, 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 ultrasound sources is no longer present,
the system is again fully functional.
If necessary, switch off automatic PDC activa‐
tion on obstacle detection, for example in car
washes, refer to page
141 , to reduce false
alarms.
