DTC Dynamic Traction Control
xDrive
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.
xDrive is the 4-wheel drive system of your X5.
The combined effects of xDrive and DSC fur-
ther optimize the traction and dynamic driving
characteristics. The 4-wheel drive system
xDrive variably distributes the drive forces to
the front and rear axle depending on the driving
situation and prevailing road conditions.
You may find it useful to briefly activate DTC
under the following special circumstances:

surfaces
HDC is a system for driving downhill in steep
terrain. This system reduces vehicle speed on
steep downhill gradients, thus allowing you to
maintain even better control of your BMW
under these conditions. The vehicle moves at
approximately walking speed without active
intervention from the driver.

Activating DTC
HDC is available for activation at vehicle speeds
below approx. 22 mph/35 km/h. When driving
down steep hills with a speed below approx.
22
mph/35 km/h, the vehicle reduces speed
automatically down to approximately walking
speed, approx. 5 mph/8 km/h, and then main-
tains this speed at a constant.
Only use HDC in transmission position D or R.
Increasing or reducing speed
Press the button briefly; the DTC indicator lamp
in the instrument cluster lights up.
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
