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
Drive-off assistant
Principle
Principle
The Antilock Braking System prevents locking
of the wheels while braking.
The drive-off assistant supports driving off on
uphill grades.
You remain able to steer your vehicle even dur-
ing full braking, which increases active driving
safety.
Driving off
1. Hold the vehicle by depressing the brake
pedal.
General information
The Antilock Braking System is ready after
each time drive-ready state is turned on.
2. Release the brake pedal and drive off
quickly.
After the brake pedal is released, the vehicle is
held in place for approx. 2 seconds.
Malfunction
Depending on the vehicle loading, the vehicle
may roll back slightly.
The warning light on the instrument
cluster illuminates.
In order to prevent rolling back when driving
off, use the parking brake.
A Check Control message is displayed.

The Antilock Braking System is not availa-
ble.
1.
Pull and release switch before driv-
ing off.
Steerability is limited during full braking.
The parking brake is set.
Have the vehicle checked immediately by an
authorized service center or another qualified
service center or repair shop.
2. Step on the accelerator pedal sufficiently to
drive off.

Driving stability control systems
CONTROLS
Overview
Dynamic Stability Control
Button in the vehicle
Principle
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.
General information
The system detects the following unstable
driving conditions, for instance:
Dynamic Stability Control
▷
▷
Skidding, which can lead to oversteering.
Loss of adhesion of the front wheels, which
can lead to understeering.
Activating/deactivating Dynamic
Stability Control
Safety information
General information
Warning
Dynamic Stability Control is automatically acti-
vated whenever drive-ready state is switched
on.
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
accident. Adjust driving style to traffic condi-
tions. Watch the surrounding traffic situation
closely, be ready to take over steering and
braking at any time, and actively intervene
where appropriate.
If Dynamic Stability Control is deactivated, driv-
ing stability is limited when accelerating and
cornering.
To support driving stability, reactivate Dynamic
Stability Control as soon as possible.
Activating/deactivating the system
1.
Press the button to open the menu.
Warning
2. "DSC OFF"
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 crit-
ical driving situations. There may be a risk of
accidents or risk of damage to property. Drive
with roof load only with activated Dynamic
Stability Control.
Dynamic Stability Control is deactivated.
3.
Press the button again to reactivate
Dynamic Stability Control.

lowed snow covered roads or loose road surfa-
ces, but with somewhat limited driving stability.

View when Dynamic Stability
Control is deactivated.
General information
The vehicle has maximum traction when Dy-
namic Traction Control is on. Driving stability
is limited during acceleration and when corner-
ing.
Indicator light illuminates: Dynamic
Stability Control is deactivated.
A brief activation of the Dynamic Traction Con-
trol may be useful in the following situations:
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.
▷

▷
When driving in slush or on uncleared,
snow-covered roads.
When driving off from deep snow or loose
ground.
When driving with snow chains.
Warning light illuminates: Dynamic Sta-
bility Control has failed or is initializing.
Driving stabilization is restricted or has
failed.
Overview
Button in the vehicle
If the warning light illuminates continuously,
have the vehicle checked immediately by an
authorized service center or another qualified
service center or repair shop.
Automatic program change
Dynamic Stability Control can be activated au-
tomatically by Forward Collision Mitigation de-
pending on the situation. Deactivate Forward
Collision Mitigation as necessary.

M sport differential
View when Dynamic Traction
Control is activated.
The M Sport differential provides for continu-
ously variable locking of the rear axle differen-
tial, depending on the driving situation. This
prevents spinning of a single rear wheel and
thereby provides optimal traction in any driving
situation.
Indicator light illuminates: Dynamic
Traction Control is activated.
The driver is responsible adapting his or her
driving style to the situation.
Automatic program change
In certain situations, Dynamic Stability Control
is activated automatically:
Variable sport steering
▷
Active Cruise Control with Distance Control
is activated.
The variable sports steering facilitates direct
and agile handling with little steering effort.
The variable sports steering works independ-
ently of the current speed, varying the steering
gear ratio in line with the steering angle.
▷
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.
Additional information:
Forward Collision Mitigation with brake inter-
vention, refer to page 160.
BMW xDrive
Principle
BMW xDrive is the all-wheel-drive system of
the vehicle. Concerted action by the BMW
xDrive and other suspension control systems
such as Dynamic Stability Control further opti-
mizes traction and driving dynamics.
General information
BMW xDrive variably distributes the drive
forces to the front and rear axles as required
by the driving situation and road conditions.
