BMW 5 Series: DTC Dynamic Traction Control
Concept
DTC is a version of the DSC Dynamic Stability Control where forward momentum is optimized.
The system ensures maximum headway on special road conditions or loose road surfaces, for instance unplowed snowy roads, but with somewhat limited driving stability.
General information
When DTC is activated, the vehicle has maximum traction. Driving stability is limited during acceleration and when driving in curves.
You may find it useful to briefly activate DTC in the following situations:
- When driving in slush or on uncleared, snowcovered roads.
- When driving off from deep snow or loose ground.
- When driving with snow chains.
