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 sand, on snowy inclines, in
slush, or on unplowed, snow-covered road
surfaces
▷ When rocking a vehicle free or starting off in
deep snow, sand, or on loose ground
▷ When driving with snow chains.
