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.

Bolts
Although, the N54 engine has an all aluminum crankcase, many of the bolts are
still aluminum as on the N52.
This is to reduce any potential confusion between steel and aluminum bolts.
Some bolts, for example, are steel
such as the cylinder head cover bolts. This is possible, due to the plastic
