1. Press the button. This opens the start menu. 2. Press the controller to open the menu. 3. Turn the controller until "Settings" is selected and press the controller. 4. Turn the controller until "Vehicle / Tires" is selected and press the controller. 5. Change to upper field if necessary. Turn the controller until "PDC" is selected and press the controller. Your BMW is equipped with an extended array of systems designed to enhance and maintain vehicle stability under extreme conditions. ABS Antilock Brake System ABS prevents locking of the wheels during braking. Safe steering response is maintained even during full braking. Active safety is thus increased. The ABS is operational every time you start the engine. Braking safely refer to page 136. CBC Cornering Brake Control When braking during curves or when braking during a lane change, driving stability and steering response are improved further. 6. Select "PDC display on" and press the controller. The PDC screen is activated. The display appears on the Control Display as soon as PDC is activated. Electronic brake-force distribution The system controls the brake pressure in the rear wheels to ensure stable braking behavior. Brake assistant When you apply the brakes rapidly, this system produces maximum braking force boosting and thus helps to achieve the shortest possible braking distance during full braking maneuvers. This system exploits all of the benefits provided by ABS. Do not reduce the pressure on the brake pedal for the duration of the full braking. System limits Even with PDC, final responsibility for estimating the distance between the vehicle and any obstructions always remains with the driver. Even when sensors are provided, there is a blind spot in which objects can no longer be detected. The system is also subject to the physical limits that apply to all forms of ultrasonic measurement, such as those encountered with tow bars and trailer couplings, or thin and wedge-shaped objects etc. 91 Online Edition for Part no. 01 41 2 600 721 - © 08/08 BMW AG Reference Mobility Communications Entertainment Navigation Driving tips Driving stability control systems Controls Low objects already displayed, e.g. curbs, can also disappear from the detection area of the sensors again before or after a continuous tone already sounds. Higher, protruding objects, e.g. ledges, cannot be detected. For this reason, drive with care; otherwise, there is a danger of personal injury or property damage. Loud sources of sound, inside and outside the vehicle, could drown out the PDC signal tone.< At a glance
