82 Do not reduce the pressure on the brake pedal
for the duration of the brake application. When
the brake pedal is released, DBC is deactivated.
DSC Dynamic Stability Control
The system prevents slip at the drive wheels
when driving off and accelerating. DSC also
detects unstable driving conditions such as
fishtailing or sliding of the front wheels. In these
cases DSC helps the vehicle safely stay on
course within the physical limits by reducing the
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The laws of physics cannot be repealed,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 variant of DSC for special road condi-
tions, e.g. uncleared snow-covered roads, that
is optimized for forward momentum. The sys-
tem ensures maximum forward momentum, but
with limited driving stability. Therefore, drive
with the corresponding caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snow-covered uphill
grades, in slushy snow or on uncleared,
snow-covered roads
>When rocking a stuck vehicle free or when
starting off in deep snow or on loose ground
>When driving with snow chains
*
Activating DTC
Press the button; 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, however not
longer than approx. 10 seconds. Interventions
promoting stability and forward momentum will
no longer be carried out. In addition, the stability
promoting intervention of the active steering
*
is deactivated, refer to page85.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To support enhanced operating stability, reacti-
vate DSC again as soon as possible.
Reactivating DSC
Press the button; the indicator lamp in the
instrument cluster goes out.

Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four tires as you drive. The
system provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
When a loss of pressure occurs, the rolling
radius changes and with it, the rotational speed
of the wheels. This change is detected and sig-
naled as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
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 snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>When driving with snow chains
*
Initializing system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving continues, the initialization is also
automatically continued.
Do not initialize the system when driving with
snow chains

Report of a flat tire
The warning lamp lights up in red. 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.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden brak-
ing and steering maneuvers. Do not exceed
a vehicle speed of 50 mph/80 km/h.
If the vehicle is not, as provided at the
factory, equipped with run-flat tires,
refer to page172, stop driving. Continued
driving after a flat tire can result in serious
accidents.<
2.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
3.In case of a complete loss of the tire inflation
pressure or obvious tire damage, you can
estimate the possible driving distance for
continued driving base on the following ref-
erence values:
>With low load:
1 to 2 persons without luggage:
approx. 155 miles/250 km.
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km.
>With full load:
4 persons, luggage compartment 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 dis-
tance and altered natural steering charac-
teristics.
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 in yellow. 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.
A t l o w s p e e d , e . g . i n a t o w n o r w h e n p a r k i n g , t h e
steering angle of the wheels is reinforced, 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 stability-pro-
moting intervention is deactivated when DSC is
switched off, refer to page82.
Malfunction
The warning lamp lights up. The active
steering is no longer operational. At low
speed, larger steering wheel move-
ments are required, while the vehicle reacts
more sensitively to steering wheel movements
in the higher road-speed range. Have the sys-
tem 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
to the left as far as it will go and then back to
the straight-ahead position.
3.Switch off the engine.
When you start the engine again, all the func-
tions of the active steering will be available once
again.
Brake Force Display
The Brake Force Display lights up in two stages
depending on how strongly you brake.
>Normal braking:
The brake lamps and the third brake lamp
go on.
>Heavy braking and braking with ABS:
In addition, the illuminated area of the rear
brake lamps is enlarged, refer to illustration.
Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and front passenger
2Coupe: Head airbags
3Front side airbags
4Knee airbag for front passenger
5Knee airbag for driver
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page44. 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 a side impact. The side airbag sup-
ports 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 rollover conditions, or rear-end
collisions.
For information on the correct sitting position,
refer to page44.

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 airbag system. This cate-
gory includes the upholstery in the center of the
steering wheel, on the instrument panel, the
side trim panels on the doors and on the Coupe,
the roof pillars along with the sides of the head-
liner. Do not attempt to remove or dismantle the
steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns.
If you note any indication of system malfunc-
tion, if you wish to have an airbag deactivated,
or if the airbag retention system is triggered in
response to an accident, you should always
entrust all inspection, repair and dismantling
operations to your BMW center. 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.
Operational readiness of airbag system
From ignition key position 1 the warning lamp
lights up briefly, indicating the operational
readiness of the entire airbag system and the
belt tensioners.
Airbag system malfunction
>The warning lamp does not light up as of
ignition key position 1.>The warning lamp lights up continuously.
Have the airbag system checked immedi-
ately if a malfunction occurs, as otherwise
there is a danger of the system not responding
in the expected manner to an impact occurring
within its normal response range.<
Convertible:
Rollover protection system
The rollover protection system is automatically
activated in the event of an accident or a critical
driving situation, extreme inclination on the lon-
gitudinal or transverse axis, or loss of ground
contact. The rollover bars located behind the
rear head restraints are deployed within frac-
tions of a second.
As a supplement to the rollover bar integrated
into the windshield frame, the rollover protec-
tion system ensures that all vehicle occupants
have the necessary headroom.
Always keep the path of movement of the
rollover protection system clear.
In less severe accidents, you are protected by
the fastened safety belt and, depending on the
severity of the accident, the belt tensioner and
the multistage airbag restraint system.<
Lowering
If the protection function was not required after
automatic activation, the rollover protection
system can be lowered again. No tools are nec-
essary for this purpose.
