Dynamic Traction Control DTC

DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:

When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads

When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground

When driving with snow chains

trols the driving and braking forces.

ment cluster: DTC is activated.
