Radar sensors
The radar sensors are located under the rear
bumper.
The system may not be fully functional in the
following situations:
▷Dirty or icy bumper.
▷Stickers on the bumper.
A Check Control message is displayed when the
system is not fully functional.
For US owners only
The transmitter and receiver units comply with
part 15 of the FCC/Federal Communication
Commission regulations. Operation is governed
by the following:
FCC ID:
▷NBG009014A.
Compliance statement:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following two
conditions:
▷This device may not cause harmful interfer‐
ence, and
▷this device must accept any interference re‐
ceived, including interference that may
cause undesired operation.
Any unauthorized modifications or changes to
these devices could void the user's authority to
operate this equipment.
Brake force display
The concept
▷During normal brake application, the outer
brake lamps light up.
▷During heavy brake application, the inner
brake lamps light up in addition.
Active Protection
The concept
The Active Protection safety package consists
of systems that are independent of each other:
▷PreCrash
▷PostCrash
PreCrash
The concept
The system is used to detect critical driving sit‐
uations that might lead to an accident. In in these
situations, preventative protection measures
are automatically undertaken to minimize the
risk in the event of an accident as much as pos‐
sible.
Critical driving situations may include:
▷Full application of the brakes.
▷Severe understeering.
▷Severe oversteering.
If the vehicle includes the collision warning fea‐
ture, impending collisions with vehicles driving

ahead or stopped in front of you can also be de‐
tected within the system's range.
Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the traffic
situation. The system may not always detect
critical situations reliably and in a timely manner.
Adapt speed to traffic situation and drive alertly;
otherwise, a risk to safety may result.◀
Function
After the safety belt is buckled, the front belts
are automatically tightened once after the vehi‐
cle is driven is away.
In critical driving situations, the following indi‐
vidual functions become active:
▷The front belts are automatically tightened.
▷Automatic closing of the windows.
▷Automatic closing of the glass sunroof.
After a critical driving situation without an acci‐
dent, the front belts are loosened again. All other
systems can be restored to the desired setting.
If the belt tension does not loosen automatically,
stop the vehicle and unbuckle the belt using the
red button in the buckle. Fasten the belt before
continuing on your trip.
PostCrash
In the event of an accident, the system can bring
the car to a halt automatically without interven‐
tion by the driver in certain situations. This can
reduce the risk of a further collision.
Depressing the brake pedal can cause the vehi‐
cle to brake harder. This interrupts automatic
braking. Depressing the accelerator pedal also
interrupts automatic braking.
After coming to a halt, the brake is released au‐
tomatically. Secure the vehicle against rolling.

Driving stability control systems
Vehicle 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.
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.◀
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 re‐
duced during acceleration and when driving in
bends.
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.

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 or when a trailer
is being used, 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.◀

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.

Press the button.
or:
Press the rocker switch while the system is in‐
terrupted.
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, Displays in

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.◀
