Control
Performance Control enhances the agility of the
vehicle.
Concept
DTC is a version of the DSC Dynamic Stability
Control where forward momentum is optimized.
To increase maneuverability, wheels are braked
individually when a sporty driving style is used.
The system ensures maximum headway on spe‐
cial road conditions or loose road surfaces, for in‐
stance unplowed snowy roads, but with some‐
what limited driving stability.
xDrive
xDrive is the all-wheel-drive system of the vehi‐
cle. Concerted action by the xDrive and DSC Dy‐
namic Stability Control further optimizes traction
and driving dynamics. The xDrive all-wheel-drive
system variably distributes the drive forces to the
front and rear axles as demanded by the driving
situation and road surface.
When DTC is activated, the vehicle has maxi‐
mum traction. Driving stability is limited during
acceleration and when driving in curves.
Drive carefully.
You may find it useful to briefly activate DTC un‐
der the following special circumstances:
▷ When driving in slush or on uncleared, snow-
covered roads.
HDC Hill Descent Control
▷ When driving off from deep snow or loose
ground.
Concept
Hill Descent Control, HDC, is a downhill control
feature that controls the vehicle speed on steep
downhill grades, for instance when driving on un‐
paved roads.
▷ When driving with snow chains.
Deactivating/activating DTC
Dynamic Traction Control
When the system is active, the vehicle moves at
the speed set by the driver, without the driver
having to depress the brake pedal.
Activating DTC
Press the button.
While HTC is controlling the speed, the system
automatically distributes the braking force to the
individual wheels. This improves vehicle drivabil‐
ity and stability. If necessary, the Antilock Brake
System prevents the wheels from locking.
TRACTION is displayed in the instru‐
ment cluster and the indicator light for DSC OFF
lights up.
Deactivating DTC
General information
Press the button again.
Hill Descent Control can be activated at speeds
below approx. 25 mph/40 km/h.
TRACTION and the DSC OFF indicator
light go out.
Speeds can be set between approx.
2 mph/3 km/h and approx. 20 mph/30 km/h.
When the vehicle is moving downhill, the system
reduces the speed to the set value, within the
physical limits.
