If the symbol appears in the display for Check
Control messages, it is possible that the condi‐
tions for operation may have not been met.
Park Distance Control, PDC
Principle
In addition to the Park Distance Control, PDC,
the rear-view camera, see page
111 , can be ac‐
tivated.
PDC assists you with parking. Slowly approach‐
ing an object in front of or behind your vehicle is
signalled by means of:
▷ Audible warning signals.
▷ Visual display.
Measurement
Ultrasonic sensors in each bumper measure the
distance.
The range is approximately 2 m, 6 ft.
An acoustic warning is only issued:
▷ From the front sensors and the two rear cor‐
ner sensors at approximately 60 cm, 24 in.
▷ For the centre rear sensors at approximately
1.50 m, 5 ft.
System limits
Also monitor the traffic situation
PDC is no substitute for your personal as‐
sessment of the traffic situation. Also monitor
the traffic situation around the vehicle by ob‐
serving it directly. Otherwise, there is a danger
that accidents might occur due to other road
users or objects located outside of detection
range of the PDC, for example.
Loud sound sources outside or inside the car
can drown out the PDC signal.◀
Avoid driving fast with PDC active
Avoid approaching an object at speed.
Avoid moving off at speed while PDC is not yet
active.
Due to physical conditions the system could
warn when it is too late.◀
Limits of the ultrasound measurement
Detection of objects might not be possible if the
physical limits of the ultrasonic measuring prin‐
ciple are exceeded, for instance by:
▷ Trailer noses and hitches.
▷ Thin or wedge-shaped objects.
▷ Low objects.
▷ Objects with corners and sharp edges.
Low objects already indicated, such as kerbs,
may enter the sensors' blind areas before or af‐
ter a continuous audible signal is given.
Higher, protruding objects such as ledges may
not be detectable.
False alarms
Under the following conditions, PDC can issue
a warning although there is no obstacle in the
detection range:
▷ In heavy rain.
▷ If the sensors are very dirty or covered with
ice.
▷ If the sensors are covered with snow.
▷ On rough road surfaces.
▷ In large, rectangular buildings with smooth
walls, for example underground car parks.
▷ Due to dense exhaust gas.
▷ Due to other ultrasonic sources, for example
sweeping machines, steam-jet cleaners or
neon lights.
▷ If the cover of the trailer tow hitch is incor‐
rectly seated.
Towing a trailer
The rear sensors are unable to perform any
meaningful measurements. They therefore do
not switch on.
A Check Control message is displayed.
