Driving comfort
CONTROLS
▷ For small children and animals.
▷ In automatic vehicle washes.
▷ Due to heavy exhaust.
▷ For persons with certain clothing, for instance
coats.
▷ Due to other ultrasound sources, for instance
sweeping machines, high pressure steam
cleaners or neon lights.
▷ With external interference of the ultrasound,
for instance from passing vehicles or loud
machines.
The malfunction is signaled by a continuous tone
alternating between the front and rear speakers.
▷ When sensors are dirty, iced over, damaged
or out of position.
As soon as the malfunction due to other ultra‐
sound sources is no longer present, the system
is again fully functional.
▷ Under certain weather conditions such as
high relative humidity, wet conditions, snow‐
fall, extreme heat, or strong wind.
To prevent false alarms, switch off automatic
PDC activation on obstacle detection, for in‐
stance in automatic vehicle washes.
▷ With tow bars and trailer couplings of other
vehicles.
▷ With thin or wedge-shaped objects.
▷ With moving objects.
Malfunction
A Check Control message is displayed.
▷ With elevated, protruding objects such as
ledges or cargo.
The range of the sensors is shown as a shaded
area on the Control Display.
▷ With objects with corners and sharp edges.
PDC has failed. Have the system checked by a
dealer's service center or another qualified serv‐
ice center or repair shop.
▷ With objects with a fine surface structure
such as fences.
▷ For objects with porous surfaces.
▷ If cargo protrudes.
Rearview camera
▷ Low objects already displayed, for instance
curbs, can move into the blind area of the
sensors before or after a continuous tone
sounds.
Concept
The rearview camera provides assistance in
parking and maneuvering backwards. The area
behind the vehicle is shown on the Control Dis‐
play.
False warnings
The system may issue a warning under the fol‐
lowing conditions even though there is no obsta‐
cle within the detection range:
Safety information
▷ In heavy rain.
▷ When sensors are very dirty or covered with
ice.
Warning
The system cannot serve as a substitute for the
driver’s personal judgment in assessing the
traffic conditions. There is a risk of accident.
Adjust driving style to traffic conditions. Watch
traffic and vehicle surroundings closely and ac‐
tively intervene where appropriate.
▷ 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.
