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. 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.< 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 for the duration of the full brake application. Adaptive brake assistant* In conjunction with the active cruise control with the stop-and-go function, the adaptive brake assistant ensures that the brake responds even more quickly during braking with the brake assistant. DSC Dynamic Stability Control DSC prevents traction loss in the driving wheels when starting off and accelerating. The system also identifies unstable driving conditions, such as a loss of traction at the rear of the vehicle or sliding of the vehicle in its front wheels. In these cases, DSC helps the vehicle maintain a safe course within physical limits by reducing engine output and through braking actions in 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 The laws of physics cannot be repealed, even with DSC.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 restrict the additional safety margin with a risky driving style, as otherwise there is a risk of an accident.< Driving stability control systems Your BMW is equipped with an extended array of systems designed to enhance and maintain vehicle stability under extreme conditions. Antilock Brake System ABS 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 126. Deactivating DSC CBC Cornering Brake Control When braking during curves or when braking during a lane change, driving stability and steering response are improved further. Electronic brake-force distribution The system controls the brake pressure in the rear wheels to ensure stable braking behavior.
