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
indicator lamp will flash continuously.Avoiding unintentional alarmsThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time to prevent a false alarm from being
triggered (in garages with elevator
ramps, for instance), or when the
vehicle is transported by trailer or train:
Lock the vehicle (arm the alarm system)
twice in succession: press button 2 on
the remote control transmitter twice
(refer to page 40), or turn the key in the
door lock to the right (lock) twice in
succession (refer to page 38).
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
system remains armed.
Interior motion sensorThe illustration depicts the transmitter
and receiver of the interior motion
sensor.
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 (refer to the
previous column) if you intend to leave
the windows or sliding/tilt sunroof
open.390de153

Safety switchWith the safety switch, you can prevent
the rear windows from being opened or
closed via the switch in the rear pas-
senger area (by children, for example).
Press the safety switch whenever
children are riding in the rear of
the vehicle. Careless use of the power
windows can lead to injury.< 390de131
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 chil-
dren unattended in the vehicle with ac-
cess to vehicle keys. Use of the key can
result in starting of the engine and op-
eration of vehicle systems such as
power sunroof, etc. Unsupervised use
of these systems can result in serious
personal injury.<
You can avoid pressure or drafts in the
passenger compartment when the sun-
roof is open or lifted by keeping the air
vents in the instrument panel open and
increasing the air supply as required.
Refer to pages 108 or 114.
If the sunroof is completely open, air
disturbances may be caused in the ve-
hicle when you are driving at higher
speeds. Close the roof as far as is nec-
essary until this natural phenomenon
ceases.
For the convenience mode via the door
lock or the remote control, refer to
page 38 or 40.
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
several inches.
If the sliding/tilt sunroof is up, then
the headliner cannot be closed.<
After the ignition has been switched off,
you can still operate the sliding/tilt sun-
roof as long as neither of the front
doors has been opened.390de636

Sliding/Tilt sunroof
*
Automatic
* opening and closing
Press the appropriate end of the control
switch past the resistance point and
then release it.
Other automatic operations are:
>With the sunroof open, press the
switch briefly toward "Lift:" the sun-
roof automatically extends to its fully
raised position.
>With the sunroof lifted, press the
switch briefly toward "Open:" the
sunroof automatically opens all the
way.
Pressing the switch again briefly stops
the motion.Safety featureIf the sliding/tilt sunroof encounters
resistance at a point roughly past the
middle of its travel when it is closing,
the closing cycle is interrupted and the
sliding/tilt sunroof will open again
slightly.Despite this safety feature, be
extremely 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.<
Sliding/tilt sunroof with glass
moonroof
*
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 sunroof. When
the sunroof is opened the headliner
retracts with it. The headliner will then
automatically remain in its retracted
position, but can be repositioned as
desired.
Power loss or malfunctionAfter interruptions in the electrical
supply (when the battery is discon-
nected, for instance), the sunroof may
only lift. To reinitialize the mechanism:
1 Raise the sliding/tilt sunroof all
the way.
2 Press and hold the switch for
approx. twenty seconds.
In the event of an electrical malfunction,
you can also operate the sliding/tilt
sunroof manually. Refer to page 198.390de637

137nRoof-mounted luggage rack
Mounting points
Access to the mounting points:
To fold up the cover (arrow), please use
the tool which is provided with the lug-
gage system.
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.
394de369
You should therefore always remember
not to exceed the approved roof
weight, the approved gross vehicle
weight or the axle weights when load-
ing the rack. You will find the specifica-
tions under "Technical data" on
page 221.
Make sure that the load is not too bulky,
and attempt to distribute it evenly.
Always load the heaviest pieces first (on
the bottom). Be sure that adequate
clearance is maintained for raising the
sliding/tilt sunroof, and that objects do
not project into the opening path of the
luggage compartment lid/tailgate.
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. Take cor-
ners gently.
The roof load increases aerodynamic
resistance: increased fuel consumption
and stress on the roof are the immedi-
ate results.

The 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.
Service Interval Display
Advanced 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, be-
390us702
cause mileage can be accumulated in
very different ways.
From a maintenance standpoint,
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.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. However, even those who
drive only short distances – significantly
less than 6,000 miles (10,000 km) annu-
ally – 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) or Warranty
and Service Guide Booklet (Cana-
dian 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.
As a precaution against rust, it might be
a good idea to have the body checked
for damage from rocks or gravel at the
same time, depending upon operating
conditions. Have your BMW center do the
maintenance and repair.
Your BMW center is always informed on
the latest maintenance work and repair
techniques and equipped with the re-
quired special tools. In addition, check-
ing parts known from experience to be
subject 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 Book-
let (Canadian models).
These entries will constitute your proof
that the vehicle has received regular
maintenance. They are also required 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, deactiva-
tion, or triggered actuation (as a
response to an accident) of the airbag
restraint system, consult your BMW
center for repairs or service operations.
380de643
Modifications may not be made on
either the wiring or the individual
components in the airbag system.
These include the padded steering
wheel hub, the instrument cluster, the
side trim panels 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 at-
tempt to remove or dismantle the steer-
ing wheel.
To ensure compliance with official
safety regulations, entrust disposal of
airbag generators to an BMW center.
Unprofessional attempts to service
the system could lead to failure in an
emergency or undesired airbag activa-
tion, either of which could result in
personal injury. < Consult your BMW center regarding
the required special procedures if you
intend to store the vehicle for longer
than three months.
