System limits
Check the traffic situation as
well
PDC cannot serve as a substitute for the driver's personal judgment of the traffic situation.
Check the traffic situation around the vehicle 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.
For technical reasons, the system may otherwise be too late in issuing a warning.
Limits of ultrasonic measurement
The detection of objects can reach the physical limits of ultrasonic measurement, e.g.:
▷ 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.
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.
