until "PDC" is selected and press the controller. even during full braking. Active safety is thus increased. The ABS is operational every time you start the engine. Braking safely, refer to page 125. EBV Electronic brake-force distribution The system controls the brake pressure in the rear wheels to ensure stable braking behavior. Controls Reference Mobility 89 Online Edition for Part no. 01 41 0 013 670 - © 02/07 BMW AG DBC Dynamic Brake Control 6. Select "PDC display on" and press the controller. The PDC screen is activated. The display is shown on the Control Display as soon as PDC is activated. When you apply the brakes rapidly, this system automatically produces the maximum braking force boost and thus helps to achieve the shortest possible braking distance during full braking. This system exploits all of the benefits provided by ABS. Do not reduce the pressure on the brake for the duration of the full braking application. System limitations 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 trailer towbars and hitches, thin or wedge-shaped objects, etc. Low objects that have already been displayed, e.g. curbs, can disappear again from the detection area of the sensors before or after a continuous tone sounds. Higher, protruding objects, e.g. ledges, cannot be detected. Loud sound sources outside or inside the car can drown out the PDC signal.< DSC Dynamic Stability Control DSC prevents the driving wheels from losing traction when you pull away from rest or accelerate. DSC also recognizes unstable driving conditions, for example if the rear of the car is about to swerve or if momentum is acting at an angle past the front wheels. In these cases, DSC helps the vehicle maintain a safe course within physical limits by reducing engine output and through braking actions at the individual wheels. The laws of physics cannot be repealed, even with DSC. An appropriate driving style always remains the responsibility of the driver. Therefore, do not reduce the additional safety margin again by taking risks, as this could result in an accident.< Driving stability control systems Your BMW has a number of systems that help to maintain the vehicle's stability even in adverse driving conditions. ABS Antilock Brake System ABS prevents locking of the wheels during braking. Safe steering response is maintained Communications Entertainment Navigation Driving tips At a glance
