Press button again.
TRACTION and the DSC OFF indica‐
tor light go out.
Performance Control
Performance Control enhances the agility of
the vehicle.
To increase maneuverability, wheels are
braked individually when a sporty driving style
is used. The resulting braking power is simul‐
taneously largely compensated by an engine
intervention.
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.

▷ Transverse gradient with degree indica‐
tion.
▷ Graphic display for the steering.
HDC Hill Descent Control
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.
Vehicle stability and maneuverability are im‐
proved on downhill gradients.
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.
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.
▷ Press the rocker switch up 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 the rocker switch down to the point
of resistance: the speed decreases gradu‐
ally.
