Driving stability control systemsVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. This then reduces braking dis‐ tance to a minimum during full braking. This
system utilizes all of the benefits provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
When equipped with Driving Assistant Plus or
with Active Cruise Control with Stop & Go
function, ACC is supported by the braking in‐
tervention if there is a possible risk of collision.
To do this, the braking force is automatically increased if the braking pressure is insufficient
when the brakes are applied.Adaptive brake assistant
In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.
Drive-off assistant
This system supports driving away on gradi‐
ents. The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive away
without delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load or when a trailer
is being used, the vehicle may roll back
slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin
rolling back.◀
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the driving
wheels when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Sub‐
ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine

speed and by applying brakes at individual
wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Indicator/warning lamps The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is
reduced during acceleration and when driving in bends.
Stabilizing interventions by the Integral Active
Steering system are only performed by the rear axle steering.
To increase vehicle stability, activate DSC
again as soon as possible.
Deactivating DSC Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and DSC OFF is displayed.
The DSC system is switched off.
Activating DSC Press the button.
DSC OFF and the DSC OFF indicator
lamp go out.Indicator/warning lamps
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is
deactivated.
DTC Dynamic Traction
Control
The concept The DTC system is a version of the DSC in
which forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.
Activating DTC Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC
OFF lights up.

Integral Active SteeringThe concept
Integral Active Steering is a combination of Ac‐
tive Steering and rear axle steering.
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.
At speeds up to approx. 37 mph/60 km/h, e.g.,
in curves, the steering angle is increased, i.e.,
steering becomes more direct.
The rear axle steering acts to increase maneu‐
verability by turning the rear wheels slightly in
a direction opposite to the front wheels.
At higher speeds, the steering angle is increas‐
ingly reduced.
The rear wheels are turned to the same angle
as the front wheels.
In critical situations, Integral Active Steering
can specifically steer the front and rear wheels
to stabilize the vehicle before the driver inter‐
venes, e.g., when braking where road condi‐
tions differ on the left and right sides of the ve‐
hicle.
InitializingIn rare cases, it may become necessary to initi‐
alize the Integral Active Steering.
The warning lamp lights up. A Check
Control message is displayed.1.With the engine running, turn the steering
wheel all the way to the left and right sev‐
eral times in a uniform manner until the
warning lamp disappears.2.Have the system checked if the warning
lamp does not go out after moving the
steering wheel approx. 6 times or if the
steering wheel is at an angle.Using snow chains
Note When snow chains are in use, refer to
page 209, rear wheel steering is deactivated.
Programs The system offers several different programs.
The programs can be selected via the Driving
Dynamics Control, refer to page 130.
SPORT
Consistently sporty tuning of the Integral Ac‐
tive Steering for greater driving agility.
COMFORT Balanced tuning between the COMFORT+ and
SPORT programs.
COMFORT+
Consistently comfort-oriented tuning of the In‐
tegral Active Steering for optimal traveling
comfort.
Malfunction
In the event of a malfunction, the steering
wheel must be turned further, while the vehicle
responds more sensitively to steering wheel
movements in the higher speed range.
The stability-enhancing intervention may be
deactivated.
Proceed cautiously and drive defensively.
Have the system checked.
Self-leveling suspension The concept
The self-leveling suspension keeps the vehicle height and ground clearance constant. The
height of the vehicle at the rear axle is main‐
tained at a predefined level under all load con‐
ditions.Seite 129Driving stability control systemsControls129

Driving comfortVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Active Cruise Control with Stop & Go function, ACC
The conceptThis system can be used to select a desired
speed that the vehicle will maintain automati‐
cally on clear roads.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied.
For safety reasons, it depends on the speed.
To maintain a certain distance, the system au‐
tomatically decelerates, applies the brakes
lightly, or accelerates again if the vehicle ahead
begins moving faster.
If the vehicle ahead of you brakes to a halt, the
system is able to detect this within the given
system limits. If the vehicle ahead of your
drives away again from a halt, your vehicle is
able to accelerate if operated accordingly.
Even if some time passes before the vehicle
drives away again, the BMW can still be accel‐
erated automatically and simply.
As soon as the road is clear, it accelerates to
the desired speed.
The speed is also maintained on downhill gra‐
dients, but may not be maintained on uphill
slopes if engine power is insufficient.General information
When ECO PRO is activated, cruise control is
also set to a driving style that saves on fuel
consumption.
Notes Personal responsibility
The system does not relieve the driver of
the responsibility to adapt his or her speed,
distance and driving style to the traffic condi‐
tions. Drive attentively, and react to the current
traffic events. Intervene actively when neces‐
sary, e.g., by braking, steering or making an
evasive maneuver, otherwise, there is danger
of an accident.◀

Therefore, drive into a curve at an appropriate
speed.
In tight curves, situations may result due to the
restricted detection range of the system in
which a vehicle driving ahead of you may not
be detected at all, or not until after a consider‐
able delay.
When approaching a curve, the system may
react briefly to the vehicles in the next lane due
to the bend of the curve. Any deceleration of
the vehicle by the system can be compensated
for by briefly accelerating. After the accelerator
pedal is released, the system becomes active
again and independently controls the speed.
Driving away In some situations, the vehicle cannot drive
away automatically, e.g., on steep inclines or
behind bumps in the road.

system fails.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situation:
▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Congestion Assistant
The concept In congestion situations, the system controls
the speed, steers independently and keeps the
vehicle in the lane.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you. The distance that the vehicle
maintains to the vehicle ahead of you can be
varied. For safety reasons, it depends on the
speed. To maintain a certain distance, the sys‐
tem automatically decelerates, applies the
brakes lightly, or accelerates again if the vehi‐
cle ahead begins moving faster.
When lane markings are detected, the system
keeps the vehicle in the lane. For this purpose,
the system steers independently as needed,
for example, during cornering.
Seite 139Driving comfortControls139
Online Edition for Part no. 01 40 2 909 749 - VI/13

General information
The congestion assistant determines speed
and distance from the vehicle in front via a ra‐
dar sensor and the position of the lane marking
via a camera.
Sensors on the steering wheel detect whether
the steering wheel is being touched.
The system is deactivated as soon as contact
with the steering wheel is no longer detected.
In order to be able to use the Congestion As‐
sistant, place your hands around the steering
wheel.
When driving with gloves or with protective
covers, contact with the steering wheel cannot
be detected by the sensors. The system in this
case cannot be used.
Notes Personal responsibility
The system does not relieve the driver of
the responsibility to adapt his or her speed,
distance and driving style to the traffic condi‐
tions. Drive attentively, and react to the current
traffic events. Intervene actively when neces‐
sary, e.g., by braking, steering or making an
evasive maneuver, otherwise, there is danger
of an accident.◀
