Dynamic Traction Control (DTC)

The functions of the DTC correspond to those of DSC with a slightly modified regulating characteristics. DTC is activated by deactivating DSC (DTC button depressed). DTC intervenes in the braking actions to imitate the function of a conventional differential lock.

Advantage: DTC allows better traction.

Vehicle stabilization intervention (e.g. reduced power output) is delayed slightly, compared to DSC, which enhances traction with a slight loss of driving stability.

This function offers a compromise between driving stability and traction, especially when accelerating and/or driving uphill on a loose surface or snow-covered road surface (surface friction requiring more slip).

DSC provides a high degree of driving stability with adequate traction, however DTC offers better traction with a slight reduction in stability. Therefore, the deactivation of DSC should be reserved for emergencies (driving in deep snow, for example).
