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.

HDC Hill Descent Control

The concept

HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep down‐
hill gradients. Without applying the brakes, the
vehicle moves at slightly more than walking
speed.
Hill Descent Control can be activated at speeds
below approx. 22 mph/35 km/h. When driving
downhill, the vehicle reduces its speed to ap‐
prox. walking speed and then keeps its speed
constant.
As long as there is active braking, the system is
on standby. The system does not brake the ve‐
hicle during this time.
Use HDC in low gears or in transmission position
D or R only.

Increasing or decreasing vehicle speed

Specify desired speed in the range from approx.
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.

Press up the rocker switch to the point of
resistance: the speed increases gradually.

Press up the rocker switch past the point of
resistance: the speed increases while the
rocker switch is pressed.

Press down the rocker switch to the point of
resistance: the speed decreases gradually.

Press down the rocker switch past the point
of resistance: when driving forward, the
speed decreases to approx. 6 mph/10 km/h;
when reversing, the speed decreases to ap‐
prox. 4 mph/6 km/h.

Activating HDC

Press the button; the LED above the but‐
ton lights up.

Deactivating HDC

Press the button again and the LED goes
out. HDC is automatically deactivated

above approx. 37 mph/60 km/h.
