Technology for driving comfort and safety Driving stability control systems Your BMW has a number of systems that help to maintain the vehicle's stability even in adverse driving 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 117. gitudinal and lateral acceleration when driving on dry surfaces, yet with reduced driving stability. Only at the absolute limit of stability does the system intervene to stabilize the vehicle by reducing engine power and applying the brakes on the wheels. In such situations, additional corrective steering maneuvers may be necessary. M Dynamic Mode is switched off every time the engine is restarted. When the M Dynamic Mode is on, stabilizing measures are performed to a limited degree only. Take action yourself, otherwise there is a risk of an accident.< To maintain vehicle stability, drive with the DSC activated and the M Dynamic Mode deactivated whenever possible.< Electronic brake-force distribution The system controls the brake pressure in the rear wheels to ensure stable braking behavior. Brake assist 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. Activating MDM Press the button on the steering wheel, refer to MDrive* on page 50. The MDM indicator lamp in the instrument cluster lights up if you previously selected the M Dynamic Mode MDM in MDrive. When the ignition is on, you can set the M Dynamic Mode via MDrive on the Control Display. iDrive, for operating principle refer to page 16. 1. "Settings" 2. "MDrive" 3. "DSC:" 4. Select "M Dynamic Mode". Dynamic Stability Control DSC DSC optimizes driving stability and traction. In addition, the system recognizes unstable driving situations such as understeering and oversteering, and helps keep the vehicle on a safe course within physical limits by reducing engine power and applying the brakes on 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 The laws of physics cannot be repealed, even with DSC.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.< M Dynamic Mode MDM* M Dynamic Mode is a mode of the Dynamic Stability Control DSC that permits greater lon82 Online Edition for Part no. 01 41 2 600 999 - © 08/08 BMW AG
