Deactivating DSC

Press the button for at least 3 seconds; the indi-
cator lamps for DSC in the instrument cluster
light up. Dynamic Traction Control DTC and
DSC have been simultaneously deactivated.
Stabilizing and drive-output promoting actions
are no longer executed.
To increase vehicle stability, activate DSC again
as soon as possible.

Activating DSC

Press the button again; the indicator lamps in
the instrument cluster go out.

For better control

If the indicator lamp flashes:
DSC controls the drive forces and
brake forces.
If the indicator lamps are on:
DSC is deactivated.

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

Press the button; the indicator lamps for DTC in
the instrument cluster come on.

For better control

If the indicator lamp flashes:
DTC controls the drive forces and
brake forces.
If the indicator lamps are on:
DTC has been activated.

Deactivating DTC

Press the button again; the DTC indicator
lamps in the instrument cluster go out.

xDrive

xDrive is your BMW's four-wheel-drive system.
The combined efforts of xDrive and DSC help to
further optimize traction and driving dynamics.
The xDrive four-wheel-drive system distributes
driving power variably to the front and rear axles
depending on the driving situation and road
conditions.

Hill Descent Control

HDC is a downhill driving assistant that reduces
your speed on steep downhill gradients and
makes it even easier to control your BMW's
handling under these conditions. The vehicle
then moves slightly faster than double walking
speed without the driver needing to intervene.
HDC can be activated as long as you are driving
under approx. 20 mph or 35 km/h. When driving
downhill at a speed of under approx. 20 mph or
