Measurement

Measurements are made by ultrasound sensors

in the bumpers.

The range is approx. 6 ft/2 m.

An acoustic warning is first given:

▷ By the front* sensors and two rear corner

sensors at approx. 24 in/60 cm.

▷ By the rear middle sensors at approx. 5 ft/

1.50 m.

System limits

Check the traffic situation as well

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.

Loud noises from outside and inside the vehicle

may prevent you from hearing the PDC's signal

tone.◀

Avoid driving quickly with PDC

Avoid approaching an object quickly.

Avoid driving away quickly while PDC is not yet

active.

Otherwise, the system may be too late in issuing

a warning for technical reasons.◀

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.

▷ With objects with corners and sharp edges.

Low objects already displayed, e.g., curbs, can

move into the blind area of the sensors before or

after a continuous tone sounds.

High, protruding objects such as ledges may not

be detected.

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 in

ice.

▷ When sensors are covered in snow.

▷ On rough road surfaces.

▷ In large buildings with right angles and

smooth walls, e.g., in underground garages.

▷ In heavy exhaust.

▷ Due to other ultrasound sources, e.g.,

sweeping machines, high pressure steam

cleaners or neon lights.

Switching on automatically

Engage transmission position R with the engine

running or the ignition switched on.

Switching off automatically

The system switches off and the LED goes out:

▷ After approx. 160 ft/50 m when driving for‐

ward.

▷ Above approx. 22 mph/36 km/h when driv‐

ing forward.

Switch on the system again if necessary.

Switching on/off manually

Press the button.

▷ On: the LED lights up.

▷ Off: the LED goes out.
