driving dynamics. xDrive variably distributes the
driving forces to the front and rear axles as de‐
manded by the driving situation and road surface.
The Driving Dynamics Control is used to change
the all-wheel distribution from traction oriented
to sport oriented.
Because of the needs-based use of the all-
wheel-drive system, Efficient4x4 yields a reduc‐
tion in consumption.
M sport differential
The active M differential provides for continu‐
ously variable locking of the rear axle differential
depending on the driving situation. This prevents
spinning of a single rear wheel and thereby pro‐
vides optimal traction in any driving situation.
The driver is responsible adapting his or her driv‐
ing style to the situation.
Integral Active Steering
Concept
The Integral Active Steering increases the ma‐
neuverability and makes a more direct steering
response possible.
General information
Integral Active Steering is a combination of varia‐
ble steering ratio and rear axle steering.
The steering is more direct because the variable
steering ratio amplifies the wheel angle while
maneuvering. The rear axle steering acts to in‐
crease maneuverability at low speeds by turning
the rear wheels slightly in the opposite direction
to the front wheels.
At higher speeds, the rear wheels are turned in
the same direction as the front wheels. This re‐
sults in, for instance better directional stability
and a more harmonious change of direction.
In critical driving situations, the Integral Active
Steering can stabilize the vehicle through pur‐
poseful steering of the rear wheels before the
driver intervenes, for instance in case of over‐
steering.
Tuning
The system offers several different tunings.
Driving mode Integral Active Steering
COMFORT
ECO PRO Comfortable, for optimal
travel comfort.
SPORT Dynamic, for greater agility.
The different tunings are assigned to the differ‐
ent drive modes of the Driving Dynamics Control.

Using snow chains
In order to guarantee free running of the wheels
when operating with snow chains, rear axle
steering of the integral active steering must be
switched off when snow chains are mounted.
Additional information:
Rear axle steering during operation with snow
chains, refer to page
337 .
Malfunction
In the event of a malfunction, the steering wheel
must be turned further at lower speeds, while the
vehicle responds more sensitively to steering
wheel movements in the higher speed range.
The stability-enhancing intervention may be de‐
activated.
Proceed cautiously and drive defensively.
Have the system checked by a dealer's service
center or another qualified service center or re‐
pair shop.
