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 in sand, 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, sand or on loose
ground
>When driving with snow chains

Function requirements
The system must have been initialized while the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Initialize the system after every correction of the
tire inflation pressure and after every tire or
wheel change.
System limits
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
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

play. In addition, an acoustic signal
sounds. There is a flat tire or a major loss in tire
inflation pressure.
Actions in the event of a flat tire
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
If the vehicle is not equipped with run-flat
tires as provided at the factory, refer to
page249, do not continue driving. Continuing
to drive with a flat tire could cause severe acci-
dents.<

When driving with a damaged tire:
1.Avoid sudden braking and steering maneu-
vers.
2.Do not exceed a speed of 50 mph/80 km/h.
If the defective tire continues to lose pres-
sure, its position will be indicated to you on
the Control Display.
3.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
may not have been initialized. The system
must then be initialized.<

Drive cautiously and do not exceed
speeds of 50 mph/80 km/h or else you
run the risk of causing an accident.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g.
reduced lane stability during braking, a longer
braking distance and altered self-steering prop-
erties.<
Vibrations or loud noises while driving can
indicate complete failure of the tire.
Reduce your speed and stop; otherwise, pieces
of the tire could come loose and cause an acci-
dent. Do not continue driving, and contact your
BMW Sports Activity Vehicle Center. The concept
Monitoring of the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
Function requirements
The system must have been reset while the
inflation pressure was correct; otherwise, reli-
able signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits

Explanation according to the NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If your vehi-
cle has tires of a different size than the size indi-
cated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly underinflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as

Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Head airbags
3Side airbags
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
observe the adjustment instructions on
page42.<
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 or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Keep the instrument cluster and window in the
region of the passenger seat free of foreign
materials, i.e. do not cover them with adhesive
film or covers and do not attach mounts, e.g. for
a navigation device or mobile phone to them.
Do not install cosmetic covers, seat cushions,
or other items on the front seats that are not
especially approved for seats with integrated
side airbags. Do not hang articles of clothing
such as jackets over the backrests.Do not attempt to remove the airbag restraint
system from the vehicle. Do not modify or
tamper with either the wiring or the individual
components in the airbag system. This includes
the upholstery in the center of the steering
wheel, on the instrument cluster, the doors, and
the roof pillars as well as the sides of the head-
liner. Do not attempt to remove or dismantle 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 air-
bag generators executed only by a BMW Sports
Activity Vehicle Center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel and has
the required explosives licenses. Otherwise
unprofessional attempts to service the system
could lead to failure in an emergency or undes-
ired airbag triggering, either of which could
result in personal injury.<
Warnings and information on the airbags is also
provided on the sun visors.
Automatic deactivation of front
passenger airbags
The occupation of the seat is detected by eval-
uating the impression on the occupied seat sur-
face of the front passenger seat. The front and
side airbags on the front passenger side are
activated or deactivated accordingly by the sys-
tem.
The current status of the front passenger
airbag, i.e. deactivated or activated, is

Technology for comfort, convenience and safety
108 indicated by the indicator lamp over the interior
rearview mirror, refer to Operating state of front
passenger airbags in the following.<
Before transporting a child on the front
passenger seat, read the safety informa-
tion and follow the instructions under Trans-
porting children safely, refer to page54.
When teenagers and adults assume certain sit-
ting positions, this can cause the front and side
airbags to deactivate. The indicator lamp for the
front passenger airbags lights up when this
occurs. In these cases, change the sitting posi-
tion so that the front passenger airbags are acti-
vated and the indicator lamp goes out. If the
desired status cannot be produced by changing
the sitting position, transport the correspond-
ing person on the rear seat. Do not fit seat cov-
ers, seat cushion padding, ball mats or other
items onto the front passenger seat unless they
are specifically recommended by BMW. Do not
lay objects under the seat which could press
against the seat from below. Otherwise a cor-
rect evaluation of the occupied seat surface
cannot be ensured.<
Operating state of front passenger
airbags
Depending on the vehicle's equipment, the
arrangement of the switches and indicator
lamps may differ somewhat.
The indicator lamp for the front passenger air-
bags indicates the operating status of the front
and side airbags on the front passenger side
depending on the seat occupation. The indica-
tor lamp shows whether the front passenger
airbags are activated or deactivated.
>The indicator lamp lights up when a child in
a child restraint device intended for the pur-pose is properly detected on the seat.
The front and side airbags on the front pas-
senger side are not activated.
Most child's seats are detected by the
system. Especially the child's seats
required by NHTSA at the time the vehicle
is manufactured. After installing a child's
seat, make sure that the indicator lamp for
the front passenger airbags lights up. This
indicates that the child's seat has been
detected and the front passenger airbags
are not activated.<
>The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient size is detected on the seat. The
front and side airbags on the front passen-
ger side are activated.
>The indicator lamp does not light up when
the seat is empty.
However, the front and side airbags on the
front passenger side are not activated.
Operational readiness of airbag system
From radio readiness, refer to page58, the
warning lamp lights up briefly, indicating the
operational readiness of the entire airbag sys-
tem and the safety belt tensioners.
Airbag system malfunction
>Warning lamp does not light up from radio
readiness.
>Warning lamp lights up continuously.
Have the airbag system checked immedi-
ately in case of a malfunction, otherwise
there is a danger that the airbag system may not
respond in the expected manner in an accident
despite an impact of corresponding intensity.<
