The concept

The DTC system is a version of the DSC in which forward momentum is optimized.

The system ensures maximum forward momentum on special road conditions, e.g., unplowed snowy roads, but driving stability is limited.

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 slush or on uncleared, snow-covered roads.
▷ When rocking the vehicle or driving off in deep snow or on loose surfaces.
▷ When driving with snow chains.
