namic Stability Control (DSC), further optimizes
traction and driving dynamics.
General information
xDrive variably distributes the driving power to
the front and rear axles as demanded by the driv‐
ing situation and road condition.
Because of the needs-based use of the all-
wheel-drive system, Efficient4x4 yields a reduc‐
tion in consumption.

Automatic Differential
Brake
Principle
Automatic Differential Brake controls the driving
power by automatic brake intervention on indi‐
vidual wheels.
General information
The function works in the same way as a differ‐
ential lock and improves traction on a loose sur‐

face, for example. The system detects when a
wheel begins to spin and automatically brakes
this wheel.
The driving force is diverted to the wheel with
better traction.
As a result, the drive torque is transferred more
efficiently to the wheels during accelerations.
HDC Hill Descent Control
Principle
HDC Hill Descent Control is a downhill control
feature that controls the vehicle speed on steep
downhill grades, for instance when driving on un‐
paved roads.
General information
When the system is active, the vehicle moves at
the speed set by the driver, without the driver
having to depress the brake pedal.
While HDC is controlling the speed, the system
automatically distributes the braking force to the
individual wheels. This improves vehicle drivabil‐
ity and driving stability. If necessary, the Antilock
Braking System prevents the wheels from lock‐
ing.
Hill Descent Control can be activated at speeds
below approx. 25 mph/40 km/h.
Speeds can be set between approx.
2 mph/3 km/h and approx. 20 mph/30 km/h.
When the vehicle is driving downhill, the system
reduces the speed to the set value, within the
physical limits.
