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

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

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
