BMW 7 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.

If DTC is activated, TRACTION is displayed in the instrument cluster.
Indicator/warning lights
The indicator light lights up:
DTC is activated.
Automatic program change
In certain situations, the DSC is activated automatically:
- If Active Cruise Control with Stop&Go function ACC is activated.
- On a braking intervention by the Intelligent Safety systems.
- The vehicle has a flat tire.
xDrive
Concept
xDrive is the all-wheel-drive system of the vehicle.
The interaction of xDrive and other suspension control systems, such as DSC Dynamic Stability Control, further optimizes traction and driving dynamics. xDrive variably distributes the driving forces to the front and rear axles as demanded by the driving situation and road surface.
The Driving Dynamics Control is used to change the all-wheel distribution from traction oriented to sport oriented.
Because of the needs-based use of the allwheel- drive system, Efficient4x4 yields a reduction in consumption.

Temperature
The tire inflation pressure depends on the tire's
temperature.
Driving or exposure to the sun will increase the
tire's temperature, thus increasing the tire inflation
pressure.
The tire inflation pressure is reduced when the
tire temperature falls again.
