Alarm system>If the indicator lamp flashes for
10 seconds when the system is
disarmed: An attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the in-
dicator lamp will flash continuously.Tilt alarm sensorThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. By doing this, you can prevent
false alarms on garage ramps or when
the vehicle is transported by trailer or
train, for instance.
Lock the vehicle twice (= arm the sys-
tem). In other words, press button 2 of
the remote control twice in succession
or lock the vehicle twice with the key.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated for as long as the sys-
tem remains armed.
Interior motion sensorThe transmitter and receiver of the inte-
rior motion sensor are located in a trim
panel in the vehicle's headliner.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
Nevertheless, you should deactivate the
interior motion sensor whenever
>children or animals are left in the
vehicle
>the windows and/or sunroof are left
open.380de628
Emergency deactivation
procedureIf the car is locked and it is not possible
to disarm the system in the normal
manner, proceed as follows:
1 Use the key to unlock the door (the
alarm sounds for 30 seconds when
opening the door)
2 Turn the key to ignition key posi-
tion 1; the central locking system
unlocks the remaining doors.
The alarm system is now disarmed. Re-
fer the problem to your BMW center.

Sliding/Tilt sunroof
To prevent injuries, exercise care
when closing the sliding/tilt sun-
roof and keep it in your field of vision
until it is shut.
Before leaving the car, switch off the
electric sunroof mechanism by taking
out the ignition key. Do not leave
children unattended in the vehicle with
access to vehicle keys. Use of the key
can result in starting of the engine and
operation of vehicle systems such as
power sunroof, etc. Unsupervised use
of these systems can result in serious
personal injury.<
To avoid pressure or drafts in the pas-
senger compartment when the sunroof
is open or lifted, keep the air vents in
the dashboard open and increase
the air supply if necessary. Refer to
pages 100, 104.
For the convenience operating mode
via the door lock or the radio remote
control, refer to page 32 or page 33.
Safety featureIf the sliding/tilt sunroof encounters re-
sistance at a point roughly past the
middle of its travel when it is closing,
the closing cycle is interrupted and the
sunroof will open again slightly.
Despite this safety feature, be ex-
tremely careful that the closing
path of the sunroof is not obstructed
whenever it is closed. Otherwise, trig-
gering the closing-force limitation may
not be ensured in some situations (with
very thin objects, for instance). You can
override this safety feature by pressing
the switch beyond the resistance point
and holding it.<
Lifting – opening – closingFrom ignition key position 1 press the
switch or slide it to the desired direction
until you feel resistance.
When lifting, the headliner retracts sev-
eral inches.
You can continue to operate the sun-
roof after the ignition has been
switched off as long as one of the front
doors has not been opened.380de615

The options and control procedures are
essentially the same as those previ-
ously described for the sliding/tilt sun-
roof. In order to open the raised roof,
press the control switch towards
"Open" until the roof has reached the
desired position.
The headliner insert slides back some-
what when you raise the roof. When the
roof is opened, the headliner retracts
with it. The headliner will then automati-
cally remain in its retracted position, but
can be repositioned as desired.
Power loss or malfunctionAfter interruptions in electrical supply
(when the battery is disconnected, for
instance), the sunroof will only lift. To
reinitialize the mechanism:
1 Raise the sliding/tilt sunroof all the
way
2 Continue to hold the switch for
approx. five seconds.
In the event of an electrical system mal-
function, the sliding/tilt sunroof can be
manually operated. Refer to page 178.380de616

Airbags
For your safety, comply with the
following instructions for the air-
bags. If you do not, the airbags may not
be able to provide their maximum pro-
tection. All passengers in the vehicle
should be aware of and comply with
this information:
The airbags are supplemental restraint
devices designed to provide extra pro-
tection; they are not a substitute for
safety belts. Wear your safety belt at all
times. The airbags will not be triggered
in the event of a minor accident, a vehi-
cle roll-over, or collisions from the rear.
In these situations, the safety belts pro-
vide optimal protection.
Adjust your seat to a position that pro-
vides maximum distance between you
and the steering wheel, the instrument
panel and the door while still allowing
comfortable and safe access to all vehi-
cle controls.
Hold the steering wheel at the rim
(hands at the "9 o'clock and 3 o'clock"
positions) in order to avoid injuries to
the hands or arms if the airbag is trig-
gered.
Never allow any objects to obstruct the
area between the airbag and the driver/
passenger.
Do not use the cover panel above the
passenger-side airbag as a storage
area.
Do not apply tape or stickers or other
material over the padded steering
wheel hub, the instrument panel, the
side trim panels of the front or rear
doors and the roof pillars or the sides of
the headliner, or modify them in any
other way.
Do not install a rear-facing child-re-
straint device on the front passenger
seat.
If your vehicle is equipped with side air-
bags in the rear, be sure that child seats
are installed correctly and with the
greatest possible distance from the
door. Do not allow children to lean out
of the child's seat in the direction of the
door. Otherwise, serious injuries could
occur if the airbag is triggered.<
Even when all these guidelines are fol-
lowed, there is still a small residual risk
of injuries to the face, hands and arms
occurring in isolated instances. The ig-
nition and inflation noise may provoke a
mild temporary hearing loss in extremely
sensitive individuals.
Airbag warning information is also pro-
vided on the sun visors.
For additional information concerning the
airbag system, refer to pages 15 6, 18 4.This is the right way a child should sit in
a child restraint when rear side bags
(arrow) are installed.

Securing the load>Secure smaller, light pieces with the
retaining straps or with a luggage
compartment net or elastic straps (re-
fer to page 39)
>For large, heavy pieces, see your
BMW center for load-securing de-
vices
*. Lashing eyes are provided at
the corners of the luggage compart-
ment for attaching these load-secur-
ing devices (refer to the illustration).
>Comply with the information en-
closed with the load-securing de-
vices.
380de613
Always position and secure the
load correctly, otherwise it can en-
danger the passengers in the event of
braking, swerving or in a crash.
Do not exceed the permissible gross
weight and the permissible axle loads
(refer to page 196). If you do so, the
operating safety of the vehicle is no
longer ensured, and you are in violation
of the law.
Do not stow heavy or hard objects in
the passenger compartment unless
they are properly secured. Improperly
secured objects would be thrown
around during braking and evasive ma-
neuvers and endanger the occupants.<
A special luggage system is available as
an option for your BMW. Please comply
with the precautions included with the
installation instructions.
Because roof racks raise the center of
gravity of the car when loaded, they ex-
ercise a major effect on its handling and
steering response.
You should therefore always remember
not to exceed the approved roof weight,
the approved gross vehicle weight or
the axle weights when loading the rack.
You will find the specifications under
"Technical Data" on page 196.
Make sure that the load is not too
heavy, and attempt to distribute it
evenly. Always load the heaviest pieces
first (on the bottom). Make sure there is
sufficient space to raise the sliding/tilt
sunroof.

Roof-mounted luggage rack
*
Secure the roof luggage correctly and
tightly to prevent it from shifting or be-
ing lost during driving (danger to follow-
ing traffic).
Drive smoothly: Avoid sudden accelera-
tion and braking maneuvers, corner
gently.
The roof load increases aerodynamic
resistance: Increased fuel consumption
and additional stresses on the vehicle's
body result from this.

The BMW Maintenance SystemThe BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and operat-
ing safety – and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle.380us008
Service Interval DisplayAdvanced technology is employed to
calculate the optimal maintenance in-
tervals, which are then indicated in the
Service Interval Display. While conven-
tional systems rely on distance traveled
alone to determine when service is due,
the BMW Maintenance System has for
years considered the actual conditions
under which the vehicle operates.
From the point of view of maintenance,
62,000 miles (100,000 km) accumulated
in short-distance urban driving are not
the equivalent of the same distance
covered at moderate speeds in long-
distance highway travel. In response to
this fact, the BMW Maintenance System
monitors operating conditions as the
basis for determining the optimum ser-
vice intervals for your individual vehicle.
The BMW Maintenance System in-
cludes the Engine Oil Service and In-
spections I and II.
Determining the maintenance intervals
according to the actual loads on the car
covers every kind of operating situation.
However, even those who drive only
short distances – significantly less than
6,200 miles (10,000 km) annually –
should have the engine oil changed at
least every 2 years since oil deteriorates
over time, regardless of use.
Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet
(Canadian models)Please refer to the Service and War-
ranty Information Booklet (US models)
or to the Warranty and Service Guide
Booklet (Canadian models) for addi-
tional information on maintenance inter-
vals and procedures.
Depending upon operating conditions,
as a precaution against rust it may be a
good idea to have the body checked for
stone damage and chips at the same
time.
Have your BMW center do the
maintenance and repair. Your BMW
center is always informed on the latest
maintenance work and repair tech-
niques and equipped with the required
special tools. In addition, checking
parts known from experience to be sub-
ject to wear is a permanent part of the
maintenance specifications. Be sure
that all maintenance work is confirmed
in the Service and Warranty Information
Booklet (US models) or in the Warranty
and Service Guide Booklet (Canadian
models). These entries will constitute
your proof that the vehicle has received
regular maintenance. They are also re-
quired in the event of a warranty claim.<

Important safety notices
Do not attempt to remove the gas
generators of the airbag restraint
system from the vehicle. Have testing
and service procedures performed by
specially-qualified technicians only. In
the event of a malfunction, deactivation,
or triggered actuation (as a response to
an accident) of the airbag restraint sys-
tem, consult your authorized BMW cen-
ter for repairs or service operations.
380de643
Modifications may not be made on ei-
ther the wiring or the individual compo-
nents in the airbag system. These in-
clude the padded steering wheel hub,
the instrument panel, the side trim pan-
els of the front or rear doors and the
roof pillars or the sides of the headliner.
Never apply adhesive materials to these
components or cover or modify them in
any way. Do not attempt to remove or
dismantle the steering wheel.
To ensure compliance with official
safety regulations, entrust disposal of
airbag generators to an authorized
BMW center.
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.< Consult your BMW center regarding the
required special procedures if you in-
tend to store the vehicle for longer than
three months.
