Adjustments
Safe seating position
For relaxed driving with as little fatigue as pos-
sible, you should select a seating position that
reflects your personal requirements. In combi-
nation with the safety belts, the head restraints
and the airbags, the seating position has a
major influence on your safety in the event of an
accident. To ensure that the vehicle's safety
systems provide you with optimal protection,
we request that you direct your careful attention
to the following section.
For supplementary information on transporting
children refer to page36.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
grip the steering wheel on the rim, with your
hands in the 3 o'clock and 9 o'clock positions,
to minimize the risk of injury to the hands or
arms in the event of the airbag being triggered
off.
Never allow any objects, individuals or animals
to obstruct the areas between passengers and
airbags.
Never use the front airbag's cover as a storage
tray or support for objects of any kind. Ensure
that the passenger is correctly seated, e.g. does
not prop feet or legs against the dashboard.
Otherwise, leg injury could result if the knee air-
bag and front airbag suddenly deployed.
Make sure that the passenger does not lean his
or her head against the side airbag, otherwise
serious injuries could result if the airbags sud-
denly deployed.<
Even when all these guidelines are observed,
the risk of injury as a result of contact with the
airbags cannot entirely be ruled out in some sit-
uations. In sensitive individuals, the ignition and
inflation noise may induce a mild hearing loss
that is temporary in most cases.
For airbag locations and additional information
on airbags, refer to page56.
Head restraint
A correctly adjusted head restraint reduces the
risk of neck injury in the event of an accident.
Adjust the head restraint in such a way
that its center is at approx. ear level. Oth-
erwise, there is an increased risk of injury in the
event of an accident.<
Head restraints, refer to page32.
Safety belt
Make sure every occupant fastens his or her
safety belt. As supplemental restraint devices,
the airbags are designed to enhance the effec-
tiveness of the safety belts, and not to replace
them.
Your vehicle offers two sitting positions, each of
which is equipped with a safety belt.
Never allow more than one person to
wear a single safety belt. Never allow
infants or small children to ride in a passenger's
lap. Make sure that the belt in the lap area sits
low against the hips and does not press against
the abdomen. The safety belt must never rest
against the throat, rub against sharp edges,
pass over hard or fragile objects or be pinched.
Fasten the safety belt around your body snugly,
ma king sure tha t it is pulled taut across your lap
and shoulder and that it is not twisted; other-
wise, the belt can slide over the hips in the event
of a frontal collision and injure your abdomen.
Avoid wearing bulky clothing and regularly pull
the belt in the upper-body area taut, otherwise
its restraining effect could be impaired.<
Safety belts, refer to page33.
Seats
Before adjusting your seat, always
observe the following precautions
Never try to adjust your seat while driving.
Otherwise, the seat could respond with
unexpected movement, and the ensuing loss of

vehicle control could lead to an accident.
On the passenger seat as well, do not incline
the backrest too far to the rear while the vehicle
is being driven, otherwise there is a danger in
the event of an accident of sliding under the
safety belt, eliminating the protection normally
provided by the belt.<
Comply with the instructions on head restraint
height on page32 and on damaged safety belts
on page34.

tened, if heavy objects are placed on the pas-
senger seat, or if driver or passenger unfasten
their safety belts.

Transporting children safely

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle, otherwise they could endanger
themselves and/or other persons by opening
the doors, for example.<
Children on the passenger seat
Children under 13 years of age or under
5 ft/150 cm in height may only be trans-
ported in child-restraint systems suitable for
their age, weight and size and if the passenger
airbags are deactivated. Otherwise, there is an
increased risk of injury in the event of an acci-
dent or should the airbags deploy.<
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child-restraint system that is
appropriate for their age, weight and size.
For a child, not an infant, certain precautions
should be taken. Position the passenger seat as
far back as possible and at the lowest level. This
important precaution is intended to maximize
the distance between the airbags and the child.
Deactivating/reactivating passenger
airbags
The passenger airbags must be deacti-
vated before using a rear-facing child-
restraint system on the passenger seat, refer
also to page37 for explanation.
BMW also recommends that the passenger air-
bags be deactivated if a child is transported in a
front-facing child-restraint system, regardless
of the age of the child. If you transport a child in
the passenger seat, not an infant in a rear-fac-
ing seat, who is properly seated and seat-belted
at all times, the potential benefits of airbags
deploying in an accident generally outweigh the
risks of the child being injured by the force of a
deploying airbag.
Therefore, you should deactivate the passen-
ger airbags only if you find it difficult to ensure
that the child will remain properly seated and seat-belted at all times.
Always position the passenger seat as far back
as possible and at the lowest level.
The above warning and recommendations are
compatible with regulations established by the
National Highway Traffic Safety Administration,
NHTSA, permitting the deactivation of passen-
ger airbags by means of an on-off switch for
members of certain at-risk groups.
Specifically, the at-risk groups are:
>Infants in rear-facing infant seats
>Persons with certain medical conditions
>Children aged 12 and under in the passen-
ger seat.
NHTSA provides this information via their web-
site, www.nhtsa.dot.gov, or via their Auto
Safety Hotline toll-free at
1-800-424-9393 or 366-0123
in Washington, D.C. area.<
Key switch for passenger
airbags
The front, side and knee airbags for the passen-
ger can be deactivated and reactivated using a
key switch. It is located on the passenger side
on the side of the dashboard.
The passenger airbags can only be deactivated
and reactivated while the vehicle is at a stand-
still and the passenger door is open.

Deactivating
Use the key to turn the key switch to the OFF
position.
The passenger airbags are deactivated in this
position. The airbags for the driver remain
active.
Reactivate the passenger airbags as soon
as a child-restraint system is no longer
installed on the passenger seat; otherwise they
may not deploy as intended in the event of an
accident.<
Reactivating
Use the key to turn the key switch to the ON
position.
The passenger airbags in the vehicle are reacti-
vated and will be triggered in certain situations.
Operational status of the passenger
airbags
>The indicator lamp remains lit when the
passenger airbags are deactivated.
>The indicator lamp is not lit when the pas-
senger airbags are activated.
When the seat is empty, the passenger
airbags are always deactivated. The indi-
cator lamp is not lit.<
Installing child-restraint
systems
Before installing a child-restraint system
on the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated, otherwise there is an increased
risk of injury if the airbags deploy. Observe the child-restraint system manufacturer's instruc-
tions for selecting, installing and using child-
restraint systems. Otherwise the protective
effect may be diminished.<
Child seat security
The passenger's safety belt can be prevented
from being pulled out in order to fasten child-
restraint systems.
To lock the safety belt
1.Secure the child-restraint system with the
belt.
2.Pull the belt strap all the way out.
3.Allow the belt strap to retract and pull it taut
against the child-restraint system.
The safety belt is locked.
To unlock the safety belt
1.Open the belt buckle.
2.Remove the child-restraint system.
3.Allow the safety belt strap to retract all the
way.

triggering of the airbag restraint system, have
the testing, repair, removal, and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to BMW
repair procedures with correspondingly trained
personnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, either of
which could result in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the
passenger airbags
An analysis of the impression in the passenger
seat cushion determines whether and how the
seat is occupied. The front and side airbags for
the passenger are activated or deactivated by
the system accordingly.
The indicator lamp in the center console
shows the current status of the passen-
ger airbags, deactivated or activated, refer to
Status of passenger airbags below.<
Before transporting a child on the pas-
senger seat, observe the safety and han-
dling instructions under Transporting children
safely, refer to page36.
Adolescents and adults sitting in certain posi-
tions could inadvertently deactivate the front
and side airbags on the passenger side; the
indicator lamp for the passenger airbags comes
on. In such cases, the passenger should change
his or her sitting position so that the passenger
airbags are activated and the indicator lamp
goes out. If the passenger airbags cannot be
restored to the desired status despite the pas-
senger changing his or her seat position, use
the key switch to activate or deactivate the pas-
senger airbags, refer to page36. Do not attach
seat covers, seat cushion padding, ball mats or
other items to the passenger seat unless they
are specifically recommended by BMW. Do not
place any items under the seat which could
press against the seat from below. Otherwise a
correct analysis of the seat cushion is not
ensured.<
Status of passenger airbags
The indicator lamp for the passenger airbags
shows the functional status of the passenger's
front and side airbags in accordance with
whether and how the passenger seat is occu-
pied. The indicator lamp shows whether the
passenger airbags are activated or deactivated.
>The indicator lamp comes on as intended
when a child in an appropriate child-
restraint system is detected on the seat.
The front and side airbags for the passen-
ger are not activated.
>The indicator lamp does not come on as
long as a person of sufficient size and in a
correct sitting position is detected on the
seat. The front and side airbags for the pas-
senger are activated.
>The indicator lamp does not come on if the
seat is empty. However, the front and side
airbags for the passenger are not activated.
Operational readiness of the airbag
system
With the ignition key in position 1 or higher, the
warning lamp comes on briefly to indicate that
the entire airbag system and the belt tensioners
are operational.
