Brake Assist
This chapter describes equipment, systems
and functions which are offered or may be of-
fered in future on a model-specific basis, even
if they are not included in the vehicle in ques-
tion.
When the brake pedal is pressed quickly,
Brake Assist automatically provides the max-
imum possible braking force assistance. This
keeps the stopping distance as short as pos-
sible in full braking situations. This takes full
advantage of the Anti-lock Braking System.
For further information:
Do not reduce the pressure on the brake pedal
during full braking.
Vehicle equipment, see page 8.
Anti-lock Braking System
Dynamic Stability Control
Principle
The Anti-lock Braking System prevents the
wheels from locking during braking.
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.
Steering control is retained even during full
braking, which enhances active road safety.
General
General
The Anti-lock Braking System is ready when-
ever you switch on drive-ready state.
The system detects the following unstable
driving conditions, for example:
▷
Loss of traction at the rear which can lead
to oversteering.
Malfunction
The warning light in the instrument
cluster is illuminated.
▷
Loss of grip at the front wheels which can
lead to understeering.
A Check Control message is shown.
Safety information
▷
▷
The Anti-lock Braking System (ABS) is not
available.
WARNING
The ease of steering is restricted in the
event of full braking.
The system does not relieve you of your per-
sonal responsibility to assess the traffic situa-
tion correctly. Due to system limits, it cannot
respond independently and appropriately in
all traffic situations. There is a risk of acci-
dent. Adapt your driving style to the traffic
conditions. Observe the traffic situation, be
ready to take over steering and braking at
Have the vehicle checked immediately by an
authorised Service Partner or another qualified
Service Partner or a specialist workshop.

WARNING
2. "DSC OFF"
When driving with a roof load, for example
with roof bars, the higher centre of gravity
can mean that driving safety is no longer
guaranteed in critical driving situations. There
is a risk of accident or material damage.
Driving with roof load only with activated Dy-
namic Stability Control.
The Dynamic Stability Control is deactiva-

Activating/deactivating Dynamic
Stability Control
If the warning light is continuously illuminated,
have the system checked immediately by an
authorised Service Partner or another qualified
Service Partner or a specialist workshop.
General
After switching on drive-ready state, Dynamic
Stability Control is activated automatically.
Driving stability during acceleration and cor-
nering is restricted if Dynamic Stability Control
is deactivated.
Automatic programme change
Dynamic Stability Control can be activated au-
tomatically by the front-collision warning, de-
pending on the situation. Deactivate the front-
collision warning if necessary.
To support driving stability, re-activate Dy-
namic Stability Control as soon as possible.

Hill Descent Control
Principle
General
Hill Descent Control provides assistance when
descending hills by regulating vehicle speed
on steep downhill gradients, for example when
driving off-road.
BMW xDrive distributes the driving power var-
iably to the front and rear axles according to
the driving situation and road condition.
The xOffroad package also adapts the all-
wheel drive system to the applicable xOFF-
ROAD driving mode.
General
When the system is active, the vehicle moves
at a speed set by the driver without the brake
pedal having to be pressed.
Display on the control display
In the Live Vehicle menu, information about
BMW xDrive can be displayed under the
following view:
While Hill Descent Control regulates vehicle
speed, the system automatically distributes
brake force to the individual wheels. Driving
stability and ease of steering are improved.
If required, the Anti-lock Braking System pre-
vents the wheels from locking.

Hill Descent Control can be activated below
approx. 40 km/h, approx. 25 mph.
Longitudinal inclination: specified in per-
cent.
Speeds between approx. 3 km/h, approx.
2 mph and approx. 30 km/h, approx. 20 mph
can be set. When driving downhill, the system
reduces the speed to the set value, within the
physical limits.

M Sport differential
The M Sport differential actively and steplessly
locks the rear axle differential according to the
driving situation. This prevents an individual
rear wheel from spinning, thus providing opti-
mum traction in all driving situations.
It is the driver's responsibility to adopt a driving
style that is appropriate to the situation.

direct steering response possible. Driving sta-
bility is also increased at high speeds.
The steering system may be faulty. The Inte-
gral Active Steering support may no longer be
provided.
General
▷
▷
▷
Larger steering movements are required at
low speeds.
The Integral Active Steering is a combination
of the variable steering gear ratio of the front
axle and the active rear-wheel steering.
The response of the vehicle is more sensi-
tive in higher speed ranges.
The rear-wheel steering increases manoeu-
vrability at low speeds by turning the rear
wheels slightly in the opposite direction to the
front wheels.
Drive cautiously and think well ahead.
Have the system checked by an authorised
Service Partner or another qualified Service
Partner or a specialist workshop.
At higher speeds, the rear wheels are turned in
the same direction as the front wheels. The re-
sulting benefits include smooth lane changes.
In critical driving situations, Integral Active
Steering can stabilise the vehicle by automat-
ically steering the rear wheels, for example
when oversteering.
Setting
The system offers various settings.
With the drive modes of the Driving Experience
Control, the system can be set to comfortable
or dynamic.
For further information:
Driving Experience Control, see page 146.
Operation with snow chains
In order to guarantee freedom of movement of
the wheels when operating with snow chains,
rear-wheel steering must be turned off when
snow chains are mounted.
For further information:
Rear-wheel steering with snow chains, see
page 373.
Malfunction
The warning light in the instrument
cluster is illuminated.
A Check Control message is shown.
