BMW 3: 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, snow-covered
roads.
- When driving off from deep snow or loose
ground.
- When driving with snow chains.
