Driving stability control systems
Vehicle features and options Brake assistant
This chapter describes model-specific equip-
ment, systems, and functions that are currently
available, or may become available in the fu-
ture, even if they are not present in the vehicle.
The brake assistant automatically applies
maximum braking assistance when the brake
pedal is depressed quickly. This reduces the
braking distance to a minimum for full braking.
Additional information:
To make full use of braking assistance, do not
reduce the pressure on the brake pedal during
full braking.
Vehicle equipment, refer to page 8.
Antilock Braking System
Dynamic Stability Control
Principle
Principle
The Antilock Braking System prevents locking
of the wheels during the braking process.
Dynamic Stability Control helps keep the vehi-
cle on a steady course in critical driving situa-
tions. The drive power is reduced depending
on the situation, and wheels can be braked
individually.
You remain able to steer your vehicle even dur-
ing full braking, which increases active driving
safety.
General information
The Antilock Braking System is ready after
each time drive-ready state is turned on.
General information
The system detects the following unstable
driving conditions, for instance:
▷
▷
Skidding, which can lead to oversteering.
Malfunction
Loss of adhesion of the front wheels, which
can lead to understeering.
The warning light on the instrument
cluster illuminates.
A Check Control message is displayed.
Safety information
Warning
▷
▷
The Antilock Braking System is not availa-
ble.
The system cannot serve as a substitute for
the driver’s personal judgment in assessing
the traffic situation. Based on the limits of
the system, it cannot independently react to
all traffic situations. There is a risk of acci-
dent, injury, and property damage. Adjust
driving style to traffic conditions. Watch the
surrounding traffic situation closely, be ready
Steerability is limited during full braking.
Have the vehicle checked immediately by an
authorized service center or another qualified
service center or repair shop.

to take over steering and braking at any time,
and actively intervene where appropriate.
Activating/deactivating the system
1.
Press the button to open the menu.
2. "DSC OFF"
Warning
Dynamic Stability Control is deactivated.
When driving with a roof load, e.g., roof bars,
the vehicle's center of gravity is higher. This
increases the risk of the vehicle tipping in
critical driving situations. There is a risk of
accident, injury, and property damage. Drive
with roof load only with activated Dynamic
Stability Control.
3.
Press the button again to reactivate
Dynamic Stability Control.
Displays in the instrument cluster
View when Dynamic Stability
Control is deactivated.
Overview
Indicator light illuminates: Dynamic
Stability Control is deactivated.
Warning light flashes: Dynamic Stabil-
ity Control is regulating the driving and
brake power. The vehicle is stabilized.
Reduce speed and modify your driving style to
the driving circumstances.
Dynamic Stability Control
Warning light illuminates: Dynamic Sta-
bility Control has failed or is initializing.
Driving stabilization is restricted or has
failed.
Activating/deactivating Dynamic
Stability Control
If the warning light illuminates continuously,
have the vehicle checked immediately by an
authorized service center or another qualified
service center or repair shop.
General information
Dynamic Stability Control is automatically acti-
vated whenever drive-ready state is switched
on.
Automatic program change
If Dynamic Stability Control is deactivated, driv-
ing stability is limited when accelerating and
cornering.
Dynamic Stability Control can be activated au-
tomatically by Forward Collision Mitigation de-
pending on the situation. Deactivate Forward
Collision Mitigation as necessary.
To support driving stability, reactivate Dynamic
Stability Control as soon as possible.
Additional information:
Forward Collision Mitigation with brake inter-
vention, refer to page 174.

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.

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.

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.

ward Collision Mitigation. Deactivate For-
ward Collision Mitigation as necessary.

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-
