DTC Dynamic Traction Control
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
Activating DTC
Briefly press the button; the DTC indicator
lamps in the instrument cluster come on.
Deactivating DTC again
Press the button again; the DTC indicator
lamps in the instrument cluster go out.
Deactivating DTC and DSC together
Press the button and hold it down for at least
3 seconds; the DSC indicator lamps in the
instrument cluster light up. Stabilizing and
drive-output promoting actions are no longer
executed.
To increase vehicle stability, activate DSC again
as soon as possible.
Reactivating DSC
Briefly press the button; the indicator lamps in
the instrument cluster go out.
