Limits of ultrasonic measurement
The detection of objects can reach the physical
limits of ultrasonic measurement, for instance:
▷
▷
▷
▷
With tow bars and trailer hitches.
With thin or wedge-shaped objects.
With low objects.
Park Distance Control PDC*
The concept
With objects with corners and sharp edges.
PDC supports you when parking.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before or
after a continuous tone sounds.
Objects that you are approaching slowly in front
of* or behind your vehicle are indicated with:
▷
▷
Signal tones.
Visual display.
High, protruding objects such as ledges may not
be detected.
Measurement
False warnings
Measurements are made by ultrasound sensors
in the bumpers.
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷
▷
In heavy rain.
▷
By the front* sensors and two rear corner
sensors at approx. 24 in/60 cm.
When sensors are very dirty or covered in
ice.
▷
By the rear middle sensors at approx. 5 ft/
▷
▷
▷
When sensors are covered in snow.
On rough road surfaces.
1.50
m.
In large buildings with right angles and
smooth walls, e.g., in underground garages.
System limits
Check the traffic situation as well
▷
▷
In heavy exhaust.
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
Engage reverse gear with the engine running or
the ignition switched on.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.◀
Switching off automatically
Avoid driving quickly with PDC
The system switches off and the LED goes out:
Avoid approaching an object quickly.
▷
After approx. 165 ft/50 m when driving for‐
ward.
Avoid driving away quickly while PDC is not yet
active.
▷
Above approx. 20 mph/30 km/h when driv‐
ing forward.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Switch on the system again if necessary.
