CONTROLS
Activating/deactivating the Dynamic
Traction Control
Dynamic Traction Control
Principle
1.
Press the button to open the menu.
The Dynamic Traction Control is a variant of
the Dynamic Stability Control where the drive
power is optimized.
2. "Traction"
Dynamic Traction Control is activated and
Dynamic Stability Control is deactivated.
The system ensures maximum drive power
on unusual road conditions, for instance unp-
lowed snow covered roads or loose road surfa-
ces, but with somewhat limited driving stability.
3.
Press the button again to reactivate
Dynamic Stability Control.
General information
Displays in the instrument cluster
The vehicle has maximum traction when Dy-
namic Traction Control is on. Driving stability
is limited during acceleration and when corner-
ing.
View when Dynamic Traction
Control is activated.
A brief activation of the Dynamic Traction Con-
trol may be useful in the following situations:
Indicator light illuminates: Dynamic
Traction Control is activated.
▷
▷
▷
When driving in slush or on uncleared,
snow-covered roads.
When driving off from deep snow or loose
ground.
Automatic program change
In certain situations, Dynamic Stability Control
is activated automatically:
When driving with snow chains.
Overview
▷
Active Cruise Control with Distance Control
is activated.
▷
In case of a brake intervention by For-
ward Collision Mitigation. Deactivate For-
ward Collision Mitigation as necessary.

▷
If the suspension control system fails.
The vehicle has a flat tire.

fort by reducing the necessary steering ef-
fort.
▷
The wheel angle is reduced in situations
that require minor or rapid corrections of
the direction of travel when driving at higher
speeds, e.g., swerving quickly or correcting
for crosswinds. In these cases, the variable
sports steering increases driving stability
when moving the steering wheel.
General information
BMW xDrive variably distributes the drive
forces to the front and rear axles as required
by the driving situation and road conditions.
Servotronic
Principle
Servotronic is a speed-dependent steering
support.
The system provides the steering force with
more support at low speeds than at higher
ones. This makes it easier to park, for instance,
and makes steering firmer when driving at
faster speeds.
Setting
The steering force adapts to the drive mode
to convey a firm, sporty feel or a comfortable
steering response.
Variable sport steering
The variable sports steering facilitates direct
and agile handling with little steering effort.
The variable sports steering responds inde-
pendently of the current speed, varying the
steering gear ratio in line with the steering an-
gle.
▷
In situations that require large movements
of the steering wheel, e.g., when maneu-
vering or turning, even minor movements of
the steering wheel will result in a greater
wheel steering angle. As a result, the varia-
ble sports steering increases steering com-
