Active M differential
The active M differential provides for continu‐
ously variable locking of the rear axle differential
depending on the driving situation. This prevents
individual rear wheels from spinning even when
DSC is switched off and in M Dynamic Mode,
enabling optimum traction to be achieved in all
driving situations.
The driver is responsible adapting his or her driv‐
ing style to the situation.
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.
