Arming and disarming the alarm
system
When the vehicle is locked or unlocked
either via the driver's door lock or with the
remote control, the alarm system is simul-
taneously armed or disarmed.
The hazard warning flashers blink once
when the alarm system has been properly
armed.
You can have different acknowledg-
ment signals set to confirm arming
and disarming.<
You can still open the luggage compart-
ment lid when the system is armed by
pressing the remote control button, refer to
page 17. When it is closed, the lid is once
again secured.
Manual operation of the luggage
compartment lid triggers the alarm.
Refer to page 19.<
To cancel an alarm:
Press the button on the remote control,
refer to page 16, or turn the ignition key to
position 1. Refer to page 36.
Indicator lamp displays
>The indicator lamp beneath the interior
mirror flashes continuously:
The system is armed
>The indicator lamp flashes when it is
being armed:
A door, the hood or luggage compart-
ment lid is not completely closed. Even
if you do not close the area causing the alert, the remaining areas are secured
and the indicator lamp flashes continu-
ously after 10 seconds.
However, the interior motion sensor is
not activated
>If the indicator lamp goes out as soon
as the system is disarmed:
No manipulation or attempted intru-
sions have been detected in the period
since the system was armed
>If the indicator lamp flashes for
10 seconds when the system is being
disarmed:
An attempted entry has been detected
in the period since the system was
armed.
After an alarm has been triggered, the indi-
cator lamp will flash continuously.
Interior motion sensor*
The system monitors the footwells and the
seating areas of the driver and passenger.
Deactivate the interior motion sensor,
refer to Avoiding unintentional alarms,
if children or animals are to remain in the
vehicle.<
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor can be deactivated at the same
time. You can do this to prevent a false
alarm from being triggered, for instance in
garages with elevator ramps or when the
vehicle is transported by train.
Lock the vehicle twice = arm the system:
Press the button on the remote control
twice in succession,
or
lock the vehicle twice with the key. Refer to
page 18.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor are
deactivated as long as the system is
armed.

Adjustments
Safe seating position
For relaxed driving with as little fatigue as
possible, you should select a seating posi-
tion that reflects your personal require-
ments. In combination with the safety belts
and airbags, the correct seating position
also plays an important role in enhancing
occupant 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 atten-
tion to the following section.
For supplementary information on trans-
porting children refer to page 33.
Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the air-
bags. Always hold the steering wheel by its
rim with hands at the 9 and 3 o'clock posi-
tions to minimize the risk of injuries to your
hands or arms in the event of airbag
deployment.
Never allow any objects, individuals or ani-
mals to obstruct the areas between pas-
sengers 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, i.e. that no feet or legs are propped
against the dashboard. Otherwise, leg
injury could result if the knee airbag and
front airbag suddenly deployed.
Never let an occupant's head rest near or
on a side airbag because the inflating air-
bag could cause a serious or fatal injury.<
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 situations. In sensitive
individuals, the ignition and inflation noise
may induce a mild hearing loss that is tem-
porary in most cases.
For airbag locations and additional infor-
mation on airbags, refer to page 56.
Sitting safely with safety belts
Always fasten your safety belt before start-
ing off. As supplemental restraint devices,
the airbags are designed to enhance the
effectiveness of the safety belts, and not to
replace them.
Your vehicle offers two sitting positions,
each of which is equipped with a safety
belt.
At all times, occupants should sit
upright and be properly restrained –
infants and small children in appropriate
child-restraint systems; larger children and
adults using the safety belts.
Expectant mothers should always wear
their safety belts, taking care to position
the lap belt against the lower hips, where it
will not exert pressure against the abdomi-
nal area.
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.
Do not route the belt across your neck, or
run it across sharp edges. Be sure that the
belt does not become caught or jammed.
Avoid twisting the belt while routing it firmly
across the hips and shoulder; wear it as
snugly against your body as possible. Do
not allow the belt to rest against hard or
fragile objects. Otherwise, the lap belt
could slide over the hips in the event of a
frontal impact, leading to abdominal injury.
Avoid wearing bulky clothing and pull on
the lap belt periodically to retension it over
your shoulders. Otherwise, the restraining
effect of the safety belt could be dimin-
ished.<
For information on using the safety belts,
refer to page 30.

Transporting children safely
Children on the passenger's
seat
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.

system, please follow the manufac-
turer's operating and safety precautions.<

Technology for safety and driving convenience
56
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.<
