Do not reduce the pressure on the brake pedal for the duration of the full braking. A message appears on the Control Display. Please note any supplementary information that appears there. To increase vehicle stability, activate DSC again as soon as possible. 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. Activating DSC Press the button; the indicator lamp in the instrument cluster goes out. Controls Reference Mobility Communications Entertainment Navigation Driving tips 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 The laws of physics cannot be repealed, even with DSC.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.< For better control The indicator lamp flashes: DSC controls the drive forces and brake forces. The indicator lamp lights up: DSC is deactivated. DTC Dynamic Traction Control DTC is a version of DSC in which the drive output is optimized for particular road conditions, e.g. unplowed snow-covered roads. The system assures the maximal drive output, but with reduced driving stability. It is therefore necessary to drive with appropriate caution. You may find it useful to briefly activate DTC under the following special circumstances: > When driving on snowy inclines, in slush, or on unplowed, snow-covered road surfaces > When rocking a stuck vehicle free or starting off in deep snow or on loose ground > When driving with snow chains* Deactivating DSC Activating DTC Press the button until the DSC indicator lamp in the instrument cluster lights up, but not longer than approx. 10 seconds. DTC Dynamic Traction Control and DSC are deactivated together. Stabilizing and drive output promoting actions are no longer executed. The stability-promoting intervention of the active steering* is also deactivated, refer to page 95. Press the button briefly; the DTC indicator lamp in the instrument cluster lights up. 89 Online Edition for Part no. 01 41 2 600 759 - © 08/08 BMW AG At a glance
