Technology for comfort, convenience and safety Technology for comfort, convenience and safety PDC Park Distance Control* The concept The PDC assists you when you are parking. Acoustic signals and an optical display* alert you to the approach of an object from behind your vehicle. To measure the distance, there are four ultrasonic sensors in each bumper. The range of these sensors is approx. 7 ft/2 m. However, an acoustic warning first sounds for the sensors at the front and at the two rear corners at approx. 24 in/60 cm, and for the center rear sensors at approx. 5 ft/1.50 m. PDC is a parking aid that can indicate the presence of objects when they are being approached slowly, as is usually the case when parking. Avoid approaching an object at high speed; otherwise, the physical circumstances could cause the system warning to be activated too late.< Switching off manually Press the button again; the LED goes out. After driving approx. 165 ft/50 m or at over approx. 20 mph/30 km/h, the system is switched off and the LED goes out. You can reactivate the system manually as needed. Signal tones An intermittent signal indicates the distance of the vehicle from an object being approached. Thus, an object detected to the left rear of the vehicle will be indicated by a signal tone from the left rear speaker, etc. As the distance between vehicle and object decreases, the intervals between the tones become shorter. If the distance to the nearest object falls to below roughly 1 ft/30 cm, then a continuous tone sounds. An intermittent tone is interrupted after approx. 3 seconds: > if you remain in front of an object that was only detected by one of the corner sensors > if you drive parallel to a wall Switching on automatically The system starts to operate approx. 1 second after you shift into reverse gear or move the selector lever into position R with the engine running or the ignition switched on. Wait this short period before driving. Malfunction The LED in the button flashes and a message appears on the Control Display. PDC is malfunctioning. Have the system checked. As a preventive measure, keep the sensors clean and free of ice or snow in order to ensure that they will continue to operate effectively. Do not spray the sensors with high-pressure cleaners for long periods and maintain a distance of at least 4 in/10 cm to them. Switching on manually Press the button; the LED lights up. 86 Online Edition for Part no. 01 41 0 013 312 - © 02/07 BMW AG
