Driving stability control systems
Vehicle features and options Brake assistant
This chapter describes all standard, country-
specific, and optional equipment offered with
the series. It also describes features and func-
tions that are not necessarily available in the
vehicle, e.g., due to the selected options or
country versions. This also applies to safety
functions and systems. When using these
functions and systems, the applicable laws
and regulations must be observed.
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.
To make full use of braking assistance, do not
reduce the pressure on the brake pedal during
full braking.
Drive-off assistant
Antilock Braking System
Principle
The drive-off assistant supports driving off on
uphill grades.
Principle
The Antilock Braking System prevents locking
of the wheels during the braking process.
Driving off
1. Hold the vehicle by depressing the brake
pedal.
You remain able to steer your vehicle even dur-
ing full braking, which increases active driving
safety.
2. Release the brake pedal and drive off
quickly.
General information
The Antilock Braking System is ready after
each engine start.
After the brake pedal is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle loading, the vehicle
may roll back slightly.
Malfunction
In order to prevent rolling back when driving
off, use the parking brake.
The warning light on the instrument
cluster illuminates.
A Check Control message is displayed.
1.
Pull and release switch before driving
off.
The parking brake is set.
▷
▷
The Antilock Braking System is not availa-
ble.
2. Step on the accelerator pedal sufficiently to
drive off.
Steerability is limited during full braking.
Have the vehicle checked immediately by an
authorized service center or another qualified
service center or repair shop.

Driving stability control systems
CONTROLS
Overview
Dynamic Stability Control
Button in the vehicle
Principle
The Dynamic Stability Control helps to keep
the vehicle on a steady course by reducing
drive power and by brake intervention on indi-
vidual wheels.
General information
The Dynamic Stability Control will detect, e.g.,
the following unstable driving conditions:
▷
▷
Skidding, which can lead to oversteering.
DSC OFF
Loss of adhesion of the front wheels, which
can lead to understeering.
Deactivating/activating the Dynamic
Stability Control
Safety information
General information
Warning
If Dynamic Stability Control is deactivated, driv-
ing stability is limited when accelerating and
cornering.
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
to take over steering and braking at any time,
and actively intervene where appropriate.
To support driving stability, reactivate Dynamic
Stability Control as soon as possible.
Deactivating the system
Hold the button down until DSC OFF
is displayed in the instrument cluster
and the DSC OFF indicator light is illu-
minated.
Warning
Activating the system
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.
Press the button.
DSC OFF and the DSC OFF indicator
light turn off.

If the Dynamic Stability Control is deactivated,
DSC OFF is displayed in the instrument clus-
ter.
Indicator lights and warning lights
Indicator light illuminates: Dynamic
Stability Control is deactivated.
Warning light flashes: Dynamic Stabil-
ity Control is regulating the drive and
brake power.
DSC OFF
Warning light illuminates: Dynamic Stability
Control has failed.
Activating/deactivating the Dynamic
Traction Control
Dynamic Traction Control
Activating the system
Press the button.
Principle
The Dynamic Traction Control is a variant of
the Driving Stability Control where the drive
power is optimized.
TRACTION is displayed in the instru-
ment cluster and the indicator light for DSC
OFF illuminates.
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.
Deactivating the system
Press the button again.
TRACTION and the DSC OFF indica-
tor light turn off.
General information
The vehicle has maximum traction when Dy-
namic Traction Control is on. Driving stability
is limited during acceleration and when corner-
ing.
Display
Display in the instrument cluster
When the Dynamic Traction Control is acti-
vated, TRACTION is displayed in the instru-
ment cluster.
A brief activation of the Dynamic Traction Con-
trol may be useful in the following situations:
▷

▷
When driving in slush or on uncleared,
snow-covered roads.

Hill Descent Control
The vehicle has a flat tire.
Principle
BMW xDrive
Hill Descent Control is a downhill control fea-
ture that adjusts the vehicle speed on steep
downhill gradients, e.g., when driving on un-
paved roads.
Principle
BMW xDrive is the all-wheel-drive system of
the vehicle. BMW xDrive and other suspension
control systems, e.g., Dynamic Stability Con-
trol, work together to further optimize traction
and driving dynamics.
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 Hill Descent Control is adjusting the
speed, the system automatically distributes the
brake power to the individual wheels. This im-
proves driving stability and steerability. If nec-
essary, the Antilock Braking System prevents
the wheels from locking.
General information
BMW xDrive variably distributes driving forces
to the front and rear axles as required by the
driving situation and road conditions.
Because of the needs-based use of the all-
wheel-drive system, Efficient4x4 yields a re-
duction in consumption.
The system can be activated 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 sys-
tem reduces the speed to the set value, within
the physical limits.
