Congratulations, and thank you for choosing a BMW. Thorough familiarity with your vehicle will provide you with enhanced control and security when you drive it. [. . . ] tions at the drive wheels to furnish the The vehicle will remain completely functionality of a conventional limitedoperational, however, without DSC. In slip differential for enhanced traction in the event of a fault, please consult your critical driving conditions such as those BMW center, refer to pages 18, 19. encountered on snow-covered road Indicator and warning lamps for surfaces, etc. DSC incorporates the functionality of the Automatic Differential Brake (ADB) and the Cornering Brake Control (CBC).

Switch the DSC and ADB off
Hold the DSC button down for at least 3 seconds. The indicator and the yellow brake warning lamps will remain on continuously. The systems for enhancing stability and traction are deactivated, and there is no active braking intervention or torque control. To maintain vehicle stability, always drive with the DSC switched on whenever possible. < The laws of physics cannot be repealed, even with DSC. An appropriate driving style always remains the responsibility of the driver. We therefore urge you to avoid using the additional safety margin of the system as an excuse for taking risks. When ADB is in its standby mode, DSC is deactivated; DSC does not intervene to enhance vehicle stability under these conditions. Allow only authorized technicians to perform service procedures on the DSC. <
Switch DSC off/activate ADB
Press the DSC button briefly; the indicator lamp comes on and stays on. In the following rare situations, it may prove useful to deactivate the ADB for a brief period: > When rocking the vehicle or starting off in deep snow or on loose surfaces > When driving on snow-covered grades, in deep snow, or on a snowcovered surface that has been packed down from being driven on > When driving with snow chains. Under these special circumstances traction is increased by deactivating the control systems that enhance traction under normal conditions.
To switch DSC and ADB back on
Press the button again; the indicator lamp or the indicator lamps will go out.
Dynamic Brake Control (DBC)
DBC is an integral component of the DSC system. The system responds to sudden, highintensity applications of force to the brake pedal by automatically braking the vehicle with maximum boost to achieve the shortest-possible braking distances during "panic stops. " This system exploits all the benefits of ABS. Do not reduce the pressure exerted against the brake pedal until the braking maneuver has been completed. DBC is deactivated when you release the brake pedal.

The concept
The Dynamic Stability Control (DSC) maintains vehicle stability, even in critical driving situations. The system optimizes vehicle stability during acceleration and when starting from a full stop, as well as optimizing traction. In addition, it recognizes unstable vehicle conditions, such as under- or oversteering, and, as far as is possible within the laws of physics, helps keeping the vehicle on a steady course by reducing the rpms and brake applications to the individual wheels. The Automatic Differential Brake (ADB-X) enhances traction in critical situations (such as those encountered on snow-covered roads) by using selective braking intervention to replace the limited-slip functions executed by the differential and transfer case in conventional drivetrains.

Indicator lamp
Overview The indicator lamp on the instrument cluster will go out shortly after the ignition has been switched on, refer to pages 18, 19. The indicator lamp flashes: DSC is actively controlling drive torque and braking intervention. The indicator lamp stays lit: DSC has been switched off manually; ADB-X is operational.
