BMW X5: DTC Dynamic Traction
Control
Principle
Dynamic Traction Control (DTC) is a version of
the Dynamic Stability Control (DSC) where drive
power is optimized.
The system ensures maximum drive power on
unusual road conditions, for instance unplowed
snow covered roads, or loose road surfaces, 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 tire chains.
