Concept  
HDC is a downhill driving assistant that auto‐  
matically controls vehicle speed on steep  
downhill gradients. Without applying the  
brakes, the vehicle moves at slightly more than  
walking speed. It the brakes are actively ap‐  
plied, the system distributes force according to  
the traction.  
Performance Control  
Performance Control enhances the agility of  
the vehicle.  
Vehicle stability and maneuverability are im‐  
proved on downhill gradients.  
To increase maneuverability, with a corre‐  
spondingly sporty driving style, wheels are  
braked individually. The resulting braking  
power is simultaneously largely compensated  
by an engine intervention.  
Hill Descent Control can be activated at  
speeds below approx. 22 mph/35 km/h. When  
driving downhill, the vehicle reduces its speed  
and then keeps its speed constant.  
Only use HDC in low gears or in selector lever  
position D or R.  
xDrive  
xDrive is the all-wheel-drive system of your ve‐  
hicle. Concerted action by the xDrive and DSC  
further optimize traction and driving dynamics.  
The xDrive all-wheel-drive system variably dis‐  
tributes the drive forces to the front and rear  
axles as demanded by the driving situation and  
road surface.  
Increasing or decreasing vehicle  
speed  
Specify desired speed in the range from ap‐  
prox. 4 mph/6 km/h to approx. 15 mph/25 km/h  
using the rocker switch of the cruise control on  
the steering wheel. Vehicle speed can be  
changed by lightly accelerating.
