Principle Of Operation: DSC

DSC calculates the current driving conditions and corrects detected driving instability through active brake interventions. For example, in the event of vehicle oversteer, DSC initiates brake intervention at the front wheel furthest from the curve to create a stabilizing, opposing torque.

In the event of vehicle understeer, active interventions at the wheels nearest to the curve provide a stabilizing counter torque. DSC stabilization is performed in all driving situations: normal running, acceleration and braking.

The DSC control module is combined with the hydraulic unit and is located on the right front strut tower in the engine compartment. The DSC function can be deactivated by the Controller in the Control Display menu and the DSC light in the instrument cluster will illuminate to alert the driver. DSC can be reactivated by the Controller or automatically when the ignition is cycled.
