the side of the bodies of the occupants in the
outer rear seats.
3 o'clock and 9 o'clock positions to keep the
risk of injury to your hands or arms as low
as possible when the airbag is deployed.
Head airbag
In the event of a side collision, the head airbag
protects the head.
▷
▷
Adjust seat and steering wheel so that
hands can be crossed over the steering
wheel. Select the settings so that the
shoulder rests against the backrest when
crossing the hands and the upper body
is as far back as possible while still main-
taining a comfortable grip on the steering
wheel.
Ejection Mitigation
The head airbag system is designed as an
ejection mitigation countermeasure to reduce
the likelihood of ejections of vehicle occupants
through side windows during rollovers or side
collision events.
Make sure that the front passenger is sit-
ting correctly, i.e., with their feet and legs in
the footwell, not resting on the dashboard.
▷
▷
Make sure that occupants keep their heads
away from the side airbag.
Knee airbag
Depending on the national-market version:
There should be no additional persons, an-
imals or objects between an airbag and a
person.
The knee airbag protects the legs in the event
of a frontal impact.
▷
▷
Dashboard and windshield on the pas-
senger's side must stay clear - do not at-
tach adhesive film or coverings and do not
attach brackets or cables, for instance for
navigation devices or mobile phones.
Protective effect
General information
Airbags are not deployed in every impact sit-
uation, e.g., in less severe accidents.
Do not bond the airbag cover panels with
adhesive, do not cover them or modify
them in any way.
Information on optimum protective
effect of the airbags
▷
▷
Do not use the cover of the front airbag on
the passenger's side as a storage area.
Warning
Keep storage compartments near the air-
bags closed, e.g., glove compartment or
center armrest.
If the seat position is incorrect, the seat
belts are fastened incorrectly or the deploy-
ment area of the airbags is impaired, the
airbag system cannot provide protection as
intended and may cause additional injuries
due to deployment. There is a risk of injury
or danger to life. Follow the information on
achieving the optimum protective effect of the
airbag system.
▷
Do not place slip covers, seat cushions,
or other objects on the front seats unless
they are specifically designed for seats with
integrated airbags.

Safety
CONTROLS
Even when you follow all instructions very
closely, injury from contact with the airbags
cannot be fully ruled out in certain situations.
Malfunction
▷
Warning light does not illuminate
when drive-ready state is turned on.
The ignition and inflation noise may lead
to short-term and, in most cases, temporary
hearing impairment in sensitive occupants.
▷
The warning light illuminates con-
tinuously.
The airbag system or the seat belt tension-
ers may not be operational. Have the vehicle
checked immediately by an authorized service
center or another qualified service center or
repair shop.
Vehicle modifications for a person with disabil-
ities may affect the air bag system; contact
BMW Customer Relations for further informa-
tion.
Warnings and information on the airbags are
also found on the sun visors.
Setting the front seat positions
Operational readiness of the airbag
system
The power that deploys the driver's/front
passenger airbags depends on the position of
the driver's/front passenger seat.
Safety information
To maintain the accuracy of this function, cali-
brate the electrical front seats as soon as a re-
spective message appears on the control dis-
play.
Warning
Individual components can be hot after de-
ployment of the airbag system. There is a risk
of injury. Do not touch individual components.
Additional information:
Seats, refer to page 97.
Automatic deactivation of
the front passenger airbags
Warning
Improperly executed work can lead to failure,
malfunction or unintentional deployment of
the airbag system. In the case of a malfunc-
tion, the airbag system might not deploy as
intended despite the accident severity. There
is a risk of injury or danger to life. Have the
airbag system checked, repaired, disassem-
bled, and scrapped by an authorized service
center or another qualified service center or
repair shop.
Principle
The system reads if the front passenger seat
is occupied by measuring the human body's
resistance.
The front passenger airbags are activated or
deactivated.
General information
Before transporting a child on the front pass-
enger seat, refer to the safety information and
instructions for children on the front passenger
seat, see Children.

tivated.
Safety information
▷
The indicator light does not illuminate
when, for instance, a correctly seated per-
son of sufficient size is detected on the
seat. The airbags on the passenger's side
are activated.
Warning
To ensure the front passenger airbag func-
tion, the system must be able to detect
whether a person is sitting in the front pass-
enger seat. The entire seat surface must be
used for this purpose. There is a risk of injury
or danger to life. Make sure that the front
passenger keeps his or her feet in the foot-
well.
Fault of the automatic deactivation
system
When transporting older children and adults,
the front passenger airbags may be deacti-
vated in certain seat positions. In this case, the
indicator light for the front passenger airbags
illuminates.
Functional requirements
To enable accurate recognition of the occupied
seat surface:
In this case, change the seat position so that
the front passenger airbags are activated and
the indicator light goes out.
▷
Do not attach covers, cushions, ball mats
or other items to the front passenger seat
unless they are specifically determined to
be safe for use on the front passenger seat.
If it is not possible to activate the airbags, have
the person sit in the rear seat.
▷
▷
Do not place objects under the seat that
can press against the seat from below.
Detected child restraint systems
Do not place any electronic devices on the
front passenger seat if a child restraint sys-
tem is to be installed on it.
The system generally detects children seated
in a child restraint system, particularly in child
restraint systems required by NHTSA at the
point in time when the vehicle was manufac-
tured. After installing a child restraint system,
make sure that the indicator light for the front
passenger airbags illuminates. This indicates
that the child restraint system has been de-
tected and the front passenger airbags are not
activated.
▷
No moisture in or on the seat.
Indicator light for the front
passenger airbags
The indicator light for the front-seat passenger
airbag in the headliner indicates the operating
state of the front-seat passenger airbag.
The light indicates whether the airbags are ei-
ther activated or deactivated.
