Driving stability control systemsVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Antilock Brake System ABS
ABS prevents locking of the wheels during brak‐
ing.
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. It thus helps to achieve the shortest
possible braking distance 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.
Adaptive brake assistant
In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical situa‐
tions. Refer also to Collision warning, refer to
page 112.Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.1.Hold the vehicle in place with the foot brake.2.Release the foot brake and drive away with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 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. Subject
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The laws of physics cannot be repealed, even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.◀

The indicator lamp lights up: DTC Dy‐
namic Traction Control is activated.
xDrive
xDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.
HDC Hill Descent Control
The concept
HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep down‐
hill gradients. Without the brakes being applied,
the vehicle moves at slightly more than twice
walking speed.
Hill Descent Control can be activated at speeds
below approx. 22 mph/35 km/h. When driving
downhill, the vehicle reduces its speed to ap‐
prox. twice walking speed and then keeps its
speed constant.
As long as there is active braking, the system is
on standby. The system does not brake the ve‐
hicle during this time.
Use HDC in low gears or in transmission position
D or R only.
Increasing or decreasing vehicle speed
Specify desired speed in the range from approx.
4 mph/6 km/h to approx. 15 mph/25 km/h using
the rocker switch of the cruise control on the
steering wheel. Vehicle speed can be changed
by lightly accelerating.▷Press up the rocker switch to the point of
resistance: the speed increases gradually.▷Press up the rocker switch past the point of
resistance: the speed increases while the
rocker switch is pressed.▷Press down the rocker switch to the point of
resistance: the speed decreases gradually.▷Press down the rocker switch past the point
of resistance: when driving forward, the
speed decreases to approx. 6 mph/10 km/h;
when reversing, the speed decreases to ap‐
prox. 4 mph/6 km/h.
Activating HDC
Press the button; the LED above the but‐
ton lights up.
Deactivating HDC Press the button again and the LED goes
out. HDC is automatically deactivated
above approx. 37 mph/60 km/h.

Driving comfortVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Active Cruise Control with
Stop & Go function, ACC
The concept
This 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 automatically
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.Buttons at a glance1System on/off, interrupt2Resume speed3Store speed4Reduce distance5Store, maintain/change speed6Increase distance

▷If active: press twice.▷If interrupted: press once.
The displays go out. The stored desired speed
and distance are deleted.
Interrupting When active, press the button.
If interrupting the system while stationary, press
on the brake pedal at the same time.
The system is automatically interrupted if:
▷The brakes are applied.▷The clutch pedal is depressed.▷Transmission position D is disengaged.▷DTC Dynamic Traction Control is activated
or DSC is deactivated.▷DSC is actively controlling stability.▷The safety belt and the driver's door are
opened when the vehicle is standing.▷The system has not detected objects for an
extended period, e.g., on a road with very lit‐
tle traffic without road edge line markings.▷Radar sensor is soiled.
Maintaining/storing the speed
Press the button.
When the system is switched on, the
current speed is maintained and stored as the
desired speed.
It is displayed in the speedometer and briefly
displayed in the instrument cluster.
When cruise control is maintained or stored,
DSC Dynamic Stability Control is switched on, if
necessary.
Changing, maintaining, and storing the
speed
The rocker switch can be pressed while the sys‐
tem is interrupted to maintain and store the cur‐
rent speed. DSC Dynamic Stability Control is
switched on, if necessary.
Adapting the desired speed
Adapt the desired speed to the road con‐
ditions and be ready to brake at all times; other‐
wise, there is the danger of an accident occur‐
ring.◀
Speed differences
Great speed differences with vehicles
driving ahead of you, e.g., when rapidly ap‐
proaching a truck or when another vehicle
swerves into your own lane, cannot be compen‐
sated for by the system.◀
Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the
vehicle reaches the stored speed if the road is
clear.
▷Each time the rocker switch is pressed to the
point of resistance, the desired speed in‐
creases or decreases by approx. 1 mph/
1 km/h.▷Each time the rocker switch is pressed past
the point of resistance, the desired speed
increases or decreases by a maximum of
5 mph/10 km/h. Max. adjustable speed:
110 mph/180 km/h.
Hold the rocker switch in position to repeat the
action.

the device should be switched off immedi‐
ately. In this case, please contact the man‐
ufacturer and only use the product after the
problem has been corrected.3.The "legal communication" specified above
refers to communication in accordance with
telecommunication regulations. Low-power
devices should withstand interference from
legal communication and ISM devices.
Collision warning with
braking function
The concept
The system issues a two-phase warning of a
danger of collision at speeds above approx.
10 mph/15 km/h. The time of these warnings
may vary depending on the current driving sit‐
uation.
The collision warning is available even if cruise
control has been deactivated.
It responds to stationary or moving objects that
are within the detection range of the radar sys‐
tem.
When the vehicle is intentionally brought into
contact with a vehicle, the collision warning is
delayed to avoid false warnings.
Warning stages
Prewarning
This warning is issued, for example, when there
is the impending danger of a collision or the dis‐
tance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention is executed with lim‐
ited braking force and for a brief period only. The
intervention cannot bring the vehicle to a com‐
plete standstill.
The braking intervention is executed only if DSC
Dynamic Stability Control, refer to page 98, is
switched on.
Adapting your speed and driving style
The acute warning does not relieve the
driver of the responsibility to adapt his or her
driving speed and style to the traffic condi‐
tions.◀
The braking intervention can be interrupted by
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When towing or tow-starting the vehicle, switch
off the collision warning with braking function to
prevent undesired interventions.
The braking function is deactivated if the DSC
Dynamic Stability Control or DTC Dynamic
Traction Control is deactivated.
Switching the warning function on/off
Press the button
