Brake assistant 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 pedal for the duration of the full braking. To increase vehicle stability, activate DSC again as soon as possible. Activating DSC Press the button; the indicator lamp in the instrument panel goes out. 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 The laws of physics cannot be repealed, even with DSC.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 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.< The indicator lamp flashes: DSC controls the drive forces and brake forces. The indicator lamps light 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 in sand, on snowy inclines, in slush or on unplowed, snow-covered road surfaces > When rocking a stuck vehicle free or starting off in deep snow, sand or on loose ground > When driving with snow chains* Deactivating DSC Activating DTC 89 Online Edition for Part no. 01 41 0 014 248 - © 08/07 BMW AG Reference A message appears on the Control Display. Please note any supplementary information that appears there. Press the button briefly; the DTC indicator lamp in the instrument panel lights up. Mobility Press the button until the DSC indicator lamp in the instrument panel lights up, but not longer than approx. 10 seconds. DTC Dynamic Traction Control and DSC are deactivated together. Stabilizing interventions are now not carried out. Communications Entertainment Navigation Driving tips Controls For better control At a glance
