DSC Dynamic Stability Control
The system prevents traction loss in the driving
wheels when starting off and accelerating. DSC
also detects unstable driving conditions such
as a fishtailing rear end or sliding of the front
wheels. In these cases, DSC helps the vehicle
maintain a safe course within physical limits by
reducing engine output and through braking
actions in the individual wheels.
The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks.<
DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snowy inclines, in slush, or
on unplowed, snow-covered road surfaces
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
Press the button briefly; the DTC indicator lamp
in the instrument cluster lights up.
Deactivating DTC again
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
Deactivating DTC and DSC together
Press the button until the DSC indicator lamp in
the instrument cluster lights up, but not longer
than approx. 10 seconds. Stabilizing and drive
output promoting actions are no longer exe-
cuted. In addition, the stability promoting inter-
vention of the active steering is deactivated,
refer to page81.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To increase vehicle stability, activate DSC again
as soon as possible.
Reactivating DSC
Press the button; the DTC indicator lamp in the
instrument cluster goes out.
To control
The indicator lamp flashes:
DSC or DTC controls the drive forces
and brake forces.
The indicator lamp lights up:
DSC and DTC are deactivated together via the
button DTC.
The indicator lamp lights up:
DTC is activated via the DTC button.

Technology for comfort, convenience and safety
80 after changing a tire or after changing a wheel or
all of the wheels.<
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
When you are driving with the compact wheel,
the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically. When driving with snow
chains or with the compact wheel, do not initial-
ize the system.<
Control Center, for principle details, refer to
page16.
1.Open the menu.
2.Select "Vehicle settings" and press the
controller.
3.Select "FTM" and press the controller.
4.Start engine, but do not start driving.5.Select "Set tire pressure" and press the
controller.
6.Select "Yes" and press the controller.
7.Start to drive.
The message "Initializing" is displayed.
The initialization finishes during driving. Then
the message "Status: Active" appears on the
Control Display again.
Indication of a flat tire
The warning lamp lights up in red and a
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire.
If identification is not possible, con-
tact a BMW center.<
3.Replace the damaged wheel, refer to
Changing a wheel on page185.
Vehicles with run-flat tires
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steering
maneuvers. Do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page174, do not
continue driving. Continuing to drive with a
flat tire could cause severe accidents.<

2.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
has not been initialized. The system must
then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, or obvious tire damage, you can
estimate the possible distance for contin-
ued driving on the basis of the following
guide values:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km
>With a full load:
4 or more persons, luggage compart-
ment full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the event of
pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibrations occur while the vehicle is
being driven, this can indicate final failure of the
damaged tire. Reduce speed and stop as soon
as possible. Do not continue driving. Contact
your BMW center.<
Malfunction
The warning lamp lights up yellow and
a message appears on the Control Dis-
play. The Flat Tire Monitor has a mal-
function or has failed. Have the system checked
as soon as possible.
Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
When you are driving in the low road speed
range, e. g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes
very direct. In the higher speed range, on the
other hand, the steering angle is reduced more
and more. This improves the handling capability
of your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page78.
Malfunction
The warning lamp lights up. The active
steering is no longer operational. At low
speeds, greater steering wheel move-
ments are required, whereas at higher speeds,
the vehicle reacts more sensitively to steering
wheel movements. Have the system checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.
Initializing system
1.Start the engine.
2.With the vehicle stationary, turn the steer-
ing wheel from the straight-ahead position
t o t h e le f t a s f a r a s i t w i ll g o a n d t h e n b a c k t o
the straight-ahead position.
3.Switch off the engine.
When you start the engine again, all the func-
tions of the active steering are available once
again.

Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and front passenger
2Head airbags in front and rear
3Side airbags in front and rear
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page38.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags are deliberately not triggered in
every impact situation, e. g. less severe acci-
dents, certain roll-over conditions, or rear-end
collisions.
The rear seat side airbags may already
have been deactivated by a BMW center.
Labels in the rear door opening should indicate
the status of your rear seat side airbags. If you
are uncertain of their status, or wish to have the
airbags activated or deactivated, please contact
your BMW center.<
For information on the correct sitting position,
refer to page38.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way. Do not attempt to remove the airbag retention system from the
vehicle. Never modify or tamper with either the
wiring or the individual components in the air-
bag system. This category includes the uphol-
stery in the center of the steering wheel, on the
instrument panel, the side trim panels on the
doors and the roof pillars along with the sides of
the headliner. Do not attempt to remove or dis-
mantle the steering wheel. Do not touch the
individual components immediately after the
system has been triggered, because there is a
danger of burns. In the event of malfunctions,
deactivation, or triggering of the airbag restraint
system, have the testing, repair, removal, and
disposal of airbag generators executed only
by a BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel and has the
required explosives licenses. Unprofessional
attempts to service the system could lead to
failure in an emergency or undesired airbag
activation, either of which could result in per-
sonal injury.<
Airbag warning information is also provided on
the sun visors.
Automatic deactivation of front
passenger airbags
Your BMW has a seat occupation detection
system. By evaluating the weight on the front
passenger seat, the system detects whether or
not the seat is occupied by a child in the child-
restraint system or an adult.
>When a child is seated in the child-restraint
system or with an empty seat, the front and
side airbags are automatically deactivated
on the passenger side.
