Deactivating/reactivating passenger
airbags
The passenger airbags must be deac-
tivated before using a rear-facing
child-restraint system on the passenger
seat, refer also to page 34 for explanation.
BMW also recommends that the passenger
airbags be deactivated if a child is trans-
ported in a front-facing child-restraint sys-
tem, regardless of the age of the child. If
you transport a child in the passenger seat,
not an infant in a rear-facing seat, who is
properly seated and seat-belted at all
times, the potential benefits of airbags
deploying in an accident generally out-
weigh the risks of the child being injured by
the force of a deploying airbag.
Therefore, you should deactivate the pas-
senger 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 estab-
lished by the National Highway Traffic
Safety Administration, NHTSA, permitting
the deactivation of passenger 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 pas-
senger seat.
NHTSA provides this information via their
website, 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.<
The concept
Passenger airbags can be deactivated/
reactivated with the vehicle ignition key.
The key switch is located on the outer pas-
senger's side of the instrument panel.
The passenger airbags can only be deacti-
vated or reactivated with the vehicle stand-
ing still, ignition off and the passenger door
open.
Deactivation
Deactivation of the passenger airbags sys-
tem deactivates the passenger front, knee
and side airbag. The airbags on the driver
side remain active.
Using the vehicle ignition key, turn the key
switch to the OFF position. Note, the pas-
senger airbags will remain deactivated with
the switch in this position.
As soon as the reason for the deacti-
vation of the passenger airbags no
longer exists, you must reactivate these air-
bags so that they can deploy in an accident
within their normal deployment range.<
Reactivating
Using the vehicle ignition key, turn the key
switch to the AUTO position.
All airbags in the vehicle are activated and
will be triggered under appropriate condi-
tions.

Passenger airbags lamp
The system checks that the airbag system
is functioning properly when the ignition
key is turned, and the indicator lamp in the
central console lights up for several sec-
onds.
>The indicator lamp lights up continu-
ously when the passenger airbags are
deactivated
>If the passenger airbags are activated, it
goes out after several seconds.
At all times, occupants should sit
comfortably upright and be properly
restrained, infants and small children in
appropriate child-restraint systems; larger
children and adults using the safety belts.
Please note that the word Airbag imprinted
on the door trim panel indicates the air-
bag's location.<
Seat position for children
This is the correct way a larger child no
longer using a child-restraint system
should sit wearing the safety belt, when the
airbag system is activated.
Installing child-restraint
systems
Before installing any child-restraint system
or child seat, read the following:
Never install a rear-facing child-
restraint system in the passenger seat
of this vehicle, unless the passenger air-
bags have been turned off and the indicator
lamp in the center console indicates that
the passenger airbags are deactivated. For
a child, not an infant, certain precautions
should be taken. Position the passenger
seat as far back as possible and at the low-
est level. This important precaution is
intended to maximize the distance
between the airbags and the child. Younger
children should be secured in an appropri-
ate forward-facing child-restraint system
that has first been properly secured. Older
children should be tightly secured with a
safety belt, sitting with their back against
the vehicle seat back. Always ensure that
all occupants, of all ages, remain properly
and securely restrained at all times.<
Always follow the manufacturer's
instructions concerning installation
and use; otherwise the system's protective
function could be impaired. After an acci-
dent, have all parts of the affected safety
belt system inspected and/or replaced by
your BMW center.<
Commercially-available child-restraint sys-
tems are designed to be secured with a lap
belt or with the lap belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint systems
can increase the risk of injury to children.
Always read and follow the instructions that
come with the system.

Technology for safety and driving convenience

Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and passenger
2Side airbags for driver and passenger
3Knee airbags for driver and passenger
Protective effect
The front airbags help protect the driver
and passenger in the event of a head-on
collision where the protection provided by
the safety belt alone would not be ade-
quate. The side airbags help provide pro-
tection in the event of a collision from the
side. Each of the side airbags is designed
to help support the seat occupant's upper
body. The knee airbags help provide addi-
tional protection in the event of a head-on
collision.
The airbags are deliberately not triggered
in every impact situation, e. g. less severe
accidents, certain roll-over conditions, or
rear-end collisions.
For information on the correct seating posi-
tion, refer to page 27.
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 individ-
ual components in the airbag system. This
category includes the upholstery in the
center of the steering wheel, on the instru-
ment panel, the side trim panels on the
doors. Do not attempt to remove or dis-
mantle the steering wheel.
Do not touch the individual components directly after the system has been trig-
gered, because there is a danger of burns.
If you note any indication of system mal-
function, if you desire to have an airbag
deactivated, or if the airbag retention sys-
tem 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 sys-
tem could lead to failure in an emergency
or undesired airbag activation, either of
which could result in personal injury.
To ensure compliance with official safety
regulations, please also entrust disposal of
airbag generators to a BMW center.<
Airbag warning information is also provided
on the sun visors.Automatic deactivation of the
passenger airbags
Before transporting a child on the
passenger seat be sure to observe
the information/instructions under Trans-
porting children safely, refer to page 33.<
Your BMW has a seat occupation detection
system. By evaluating the weight on the
passenger's 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, the front, side and
knee airbags are automatically deacti-
vated on the passenger's side.
>When an adult is traveling in the front
seat or it is unoccupied, the front, side
and knee airbags remain active on the
passenger's side.
Although not desired, it can occur in
the case of heavier children that the
passenger airbags remain active or, in the
case of very light adults or young persons,
that the passenger airbags are deactivated.
The condition of the passenger airbag sys-
tem is shown by the indicator lamp in the
central console, refer to Indicator lamps
below. If the indicator lamp signals that the
passenger airbags are active and you wish

them to be deactivated, the airbags have to
be deactivated with the vehicle ignition key
and the key switch on the outer passen-
ger's side of the instrument panel. Apart
from passengers, do not place any addi-
tional objects on the passenger seat. Do
not fit seat covers, seat cushion padding,
ball mats or other items to the passenger
seat unless they are specifically recom-
mended by BMW. Do not place any items
under the seat. Otherwise, the function of
the seat occupation detection could be
impaired.<
Indicator lamps
Airbag system operational
The airbag indicator lamp in the instrument
cluster indicates the operational readiness
of the entire airbag system and the safety
belt tensioners as of ignition key position 1.
The indicator lamp goes out after a few
seconds.
The indicator lamp in the central console
signals whether or not the passenger air-
bag system is activated or deactivated as
of ignition key position 1.
This lamp pertains only to the passen-
ger airbag system.<>The indicator lamp goes out after a few
seconds:
The passenger airbags are active, e. g.
when an adult is traveling in the vehicle
or the seat is unoccupied
>The indicator lamp lights up continu-
ously:
The passenger airbags are deactivated,
e. g. when a child is traveling in the vehi-
cle in the child-restraint system.
For more information on the operating prin-
ciple of the passenger airbag system and
seat occupation detection, refer to Auto-
matic deactivation of the passenger air-
bags.
Airbag system malfunction
A system malfunction could prevent
the system from responding in the
expected manner to an impact occurring
within its normal response range.
Please have the airbag system inspected
immediately at a BMW center.<
There is a fault in the airbag system
if the airbag indicator lamp behaves
as follows:
>The indicator lamp does not light up as
of ignition key position 1
>The indicator lamp remains on continu-
ously
>The indicator lamp lights up while the
vehicle is being driven.
