TRACTION and the DSC OFF indica‐
tor lamp go out.
Performance Control Performance Control enhances the agility of
the vehicle.
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.
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
downhill gradients. Without applying thebrakes, 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 approx. 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
vehicle during this time.
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.▷Press the rocker switch down past the
point of resistance: when driving forward,
the speed decreases to approx.
6 mph/10 km/h; when reversing, the speed
decreases to approx. 4 mph/6 km/h.Seite 122ControlsDriving stability control systems122

Information WARNING
If the approved gross vehicle weight of
the towing vehicle is lighter than the vehicle to be towed, the tow fitting can tear off or it will
not be possible to control the vehicle's re‐
sponse. There is risk of an accident! Make sure
that the gross vehicle weight of the towing ve‐
hicle is heavier than the vehicle to be towed.◀
CAUTION
If the tow bar or tow rope is attached in‐
correctly, damage to other vehicle parts can
occur. There is risk of property damage. Cor‐
rectly attach the tow bar or tow rope to the tow
fitting.◀
