tomary stabilizing actions.
For monitoring purposes
When the indicator lamp flashes:
To increase vehicle stability, reactivate DSC as
soon as possible.
DTC is controlling the drive forces and
braking forces.
When the indicator lamp lights up:
DTC is activated.
Activating DSC
Press the button again; the indicator lamp in the
instrument cluster goes out.
Deactivating DTC
For monitoring purposes

forces.
xDrive
When the indicator lamp lights up:
DSC is deactivated.
xDrive is the all-wheel drive system of your
BMW. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv-
ing characteristics. The all-wheel drive system
xDrive variably distributes the drive torque to
the front and rear axle depending on the driving
situation and prevailing road conditions.
DTC Dynamic Traction Control
DTC is a variation of DSC that is optimized for
forward momentum for particular road condi-
tions, e.g. unplowed snow-covered roads. In
this mode, the system assures maximum for-
ward momentum, but with limited driving stabil-
ity. For this reason, drive with corresponding
caution.
HDC Hill Descent Control
The concept
In the following exceptional circumstances, it
may be useful to temporarily activate DTC:
HDC is a system for hill descent assistance that
reduces the speed on steep downward inclines
and makes it even easier to control the driving
characteristics of your BMW under these condi-
tions. The vehicle moves at slightly more than
walking speed without active intervention from
the driver.
>
When driving on snow-covered inclines, in
slush, or on unplowed, snow-covered roads
>
When freeing a stuck vehicle or starting up
in deep snow, sand, or on a loose ground
surface
You can activate HDC at vehicle speeds below
approx. 20 mph/35 km/h. If it is traveling down a
steep slope at a speed below approx. 20 mph/

Activating DTC
35
km/h, the vehicle then automatically decel-
erates down to slightly more than walking
speed, approx. 5 mph/8 km/h, and then keeps
this speed constant.
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range extending from approx. 3 mph/5 km/h to
15
mph/25 km/h.
You can specify a target speed within the same
range by using the +/– buttons of the cruise
control on the steering wheel.
Press the button; the DTC indicator lamp in the
instrument cluster lights up.
