DSC Dynamic Stability Control DSC optimizes vehicle stability and traction. It also detects unstable driving states such as understeering and oversteering, and helps keep the vehicle on course within the physical limits by reducing the engine output and by braking at the wheels. The DSC is operational every time you start the engine. The laws of physics cannot be repealed, even with DSC.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 further by taking risks.< The indicator lamp stays lit: M Dynamic Mode is activated. The indicator lamp lights up continuously and the DSC indicator lamp flashes: the M Dynamic Mode is active and controls the drive and braking forces. You activate the M Dynamic Mode with the button on the steering wheel, refer to MDrive on page 52. With the ignition switched on you can set MDrive on the Control Display. iDrive, for operating principle refer to page 16. 1. Press the button. This opens the start menu. 2. Press the controller to open the menu. 3. Select "MDrive" and press the controller. 5. Select "M Dynamic Mode" and press the controller. 4. Select "DSC" and press the controller. Indicator lamp The indicator lamp goes out shortly after the engine is started. The indicator lamp flashes: DSC controls the drive forces and brake forces. The indicator lamp stays lit: DSC is deactivated. M Dynamic Mode MDM The M Dynamic Mode is a mode of the DSC Dynamic Stability Control. It enables driving with greater longitudinal and lateral acceleration on dry road surfaces, however with limited vehicle stability. The system does not provide stabilizing intervention by reducing the engine output and braking at the wheels until the absolute driving limit is reached. Additional steering corrections may also be required in this driving state. The M Dynamic Mode is deactivated each time the engine is started. With the M Dynamic Mode activated, stabilizing interventions are only carried out to a reduced degree. Take action yourself, otherwise there is a risk of an accident.< To maintain vehicle stability, drive with DSC activated and the M Dynamic Mode deactivated whenever possible.< You can also activate and deactivate the M Dynamic Mode with the MDM button. Indicator lamp The indicator lamp goes out shortly after the engine is started. 81 Online Edition for Part no. 01 41 2 600 738 - © 08/08 BMW AG Reference Mobility Communications Entertainment Navigation Driving tips Controls Activating MDM At a glance
