reduced driving stability. It is therefore neces-

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*
HDC is a downhill driving assistant that controls 
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 
35 km/h, the vehicle's speed is automatically 
reduced to slightly more than double walking 
speed and maintained.
Increasing or decreasing speed
By accelerating or braking you can change this 
speed within a range from approx. 3 to 15 mph, 
approx. 5 to 25 km/h.
You can specify a target speed within the same 
range using the cruise control
*
 lever on the 
steering column.
To increase speed
To decrease speed
Activating HDC
Press the button; the LED lights up.
When the vehicle is being braked automatically, 
the LED flashes.
