90nPDC Park Distance Control* Automatic operation When the engine is running or the ignition is switched on, the PDC system starts to operate automatically approx. one second after you shift into reverse or move the selector lever into the R position. Wait this short period before backing up. The concept PDC provides extra safety and convenience during parking maneuvers. Signal tones indicate the current distance to an object behind or in front of your vehicle. To do this, four ultrasonic sensors in the front and rear bumpers each measure the distance to the nearest object. The detection range of the front sensors and the two sensors located at the ends of the rear bumper is approx. 2 ft/60 cm, while the rear center sensors can detect objects up to a distance of approx. 5 ft/1.50 m. PDC is a parking aid that can indicate objects when they are approached slowly, as is usually the case when parking. Avoid approaching objects too quickly; otherwise the physical circumstances may cause the system to issue the warning too late.< Manual activation Press the button; the LED lights up. Manual deactivation Press the button again; the LED goes out. Automatic deactivation After driving a distance of more than approx. 95 ft/30 m or exceeding a speed of approx. 20 mph/30 km/h, the system switches off and the LED goes out. You may switch the system on again manually as needed. 530de418 Online Edition for Part No. 01 41 0 159 867 - © 07/05 BMW AG
