Dynamic Traction Control (DTC)

To improve propulsion, the ASC slip thresholds can be increased up to a speed of 45 mph (70 km/h). The permissible slip is doubled which offers advantages when driving on poor roads and in heavy snow (increased rear wheel spin is permissible).

When chassis dynamics increase as measured by the yaw rate sensor, the slip thresholds are reduced back to the normal mode for stability reasons. The DTC function can be activated/deactivated by the Controller in the Control Display menu.

When the DTC traction mode is activated, the "DTC" light is illuminated above the DSC safety light (in the instrument cluster).
