For your own safety
Use unleaded gasoline only. Fuels
containing up to and including 10 %
ethanol or other oxygenates with up to
2.8 % oxygen by weight – i.e. 15 % MTBE or
3% methanol plus an equivalent amount of
co-solvent – will not void the applicable
warranties respecting defects in materials
or workmanship. Field experience has indi-
cated significant differences in fuel quality –
i.e. volatility, composition, additives, etc. –
among gasolines offered for sale in the
United States and Canada. The use of poor
quality fuels may result in drivability, start-
ing and stalling problems especially under
certain environmental conditions, such as
high ambient temperature and high alti-
tude.
Should you encounter driveability prob-
lems that you suspect could be related to
the fuel you are using, we recommend that
you respond by switching to a recognized
high-quality brand.
Failure to comply with these recommenda-
tions may result in unscheduled mainte-
nance.
Follow the relevant safety rules when you
are handling gasoline.<

Installation
Insert the wind deflector in the guides pro-
vided on the rollover bars.
The wind deflector panels inserted in the
rollover bars cannot be removed.
Clothes hooks
Located on the wind deflector panel in the
rollover bars.
Do not hang heavy objects on the
hooks. If you do so, personal injury
could result during braking or evasive
maneuvers, for example.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage
compartment lid is opened
>When attempts are made to start the
vehicle
>To movement inside the vehicle – inte-
rior motion sensor
>To alterations in the vehicle tilt, e.g. as
would occur during attempts to steal
the wheels or tow the vehicle
>To interruption of battery voltage.
The alarm produced by the system in the
event of unauthorized vehicle entry and
attempted theft depends on the country
version:
>Sounding of an acoustical alarm for
30 seconds
>Activation of the hazard warning flash-
ers for approx. five minutes.
Arming and disarming the alarm sys-
tem
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 open the luggage compartment lid
when the system is armed by pressing the
remote control button. Refer to page 19.
When it is closed, the lid is once again
secured.
Manual operation of the luggage
compartment lid triggers the alarm.
Refer to page 21.<
To cancel an alarm:
Press the button on the remote control,
refer to page 18, or turn the ignition key to
position 1. Refer to page 38.
Indicator lamp displays
>The indicator lamp beneath the interior
mirror flashes continuously:

>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

Adjustments
Safe seating position
For relaxed and fatigue-free driving you
should select a seating position that
reflects your personal requirements. The
correct seating position combines with
safety belts and airbags to enhance occu-
pant 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 34.
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 positions,
to minimize the risk of injuries to your
hands or arms in the event of airbag
deployment. Never allow any objects, indi-
viduals 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.
Never allow front passengers to rest their
feet or legs on the airbag cover.<
For airbag locations and additional infor-
mation on airbags, refer to page 33.
Sitting safely with safety belts
Never allow more than one person to
wear a single safety belt. Never allow
infants or small children to ride in a passen-
ger's lap. Avoid twisting the belt while rout-
ing it firmly across the pelvis and shoulder,
wear it as snugly against your body as pos-
sible. Do not allow the belt to rest against
hard or fragile objects. 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 wearing
bulky clothing and pull on the lap belt peri-odically to retension it over your shoulders.
In the event of a frontal impact, a loose lap
belt could slide over your hips, leading to
abdominal injury. In addition, the safety
belt's restraint effectiveness is reduced if
the belt is worn loosely. Expectant mothers
should always wear their safety belts, tak-
ing care to position the lap belt against the
lower hips, where it will not exert pressure
against the abdominal area.<
For information on using the safety belts,
refer to page 31.
Seats
Before adjusting your seat, always
observe the following precautions
Never try to adjust your seat while
operating the vehicle. The seat could
respond with an unexpected movement,
and the ensuing loss of vehicle control
could result in an accident. Never ride with
the backrest inclined to an extreme angle –
especially important for the front passen-
ger to remember. If you do so, there is a
risk that you will slide under the safety belt
in the event of an accident, thus reducing
the protection provided by the safety belt.<
Seat adjustment

To unlock the safety belt
1.Press the red button in the belt buckle
2.Hold the belt
3.Guide the belt back into its reel.
If the safety belt system has been
stressed as a result of an accident or
if it has been damaged in any other way:
have the safety belt mechanism, including
the safety belt tensioners and any child-
restraint systems, replaced by your BMW
center. In addition, have your BMW center
inspect the safety belt anchors. Otherwise,
the system cannot be guaranteed to pro-
vide the required protection in the event of
an accident.<
Steering wheel
Adjustments
Never attempt to adjust the steering
wheel while driving the vehicle. It
could respond with unexpected move-
ment, posing a potential accident hazard.<
1.Push the locking lever downward
2.Adjust the steering column's reach and
rake to suit your seat position
3.Pull the lever back in.

Interior and exterior mirrors with
automatic dimming feature*
This mirror automatically dims through an
infinitely variable range and switches auto-
matically to its clear, undimmed mode
whenever you engage reverse gear or
place the selector lever in position R.
To ensure that the mirror continues to
operate properly, keep the two photocells
clean and unobstructed. One photocell is
positioned in the mirror's lens, see arrow,
while the other is slightly offset on the
opposite side of the mirror. Do not obstruct
the area between the interior rearview mir-
ror and the windshield; do not apply stick-
ers to the area of the windshield in front of
the mirror.
Airbags
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.
Do not remove or exchange the floor
mat on the passenger side. It is a
component of the safety system.<
For information on the correct seating posi-
tion, refer to page 29.
Indicator lamp
The indicator lamp in the instrument
cluster shows the airbag system's
operational readiness when the
ignition key is in position 1 or higher.
System operational:
>The indicator lamp comes on briefly
when the ignition key is in position 1 or
higher.
System malfunction:
>The indicator lamp fails to go out after
the engine has been started, or it
comes on again during normal driving.
BMW recommends that you respond
to any malfunctions in the system by
immediately having it inspected at your
BMW center; otherwise the airbag could
fail to respond in an accident that would
normally trigger airbag deployment.<
For your safety, comply with the fol-
lowing instructions for the airbags. If
you do not, the airbags may not be able to
provide their full protection. All passengers
in the vehicle should be aware of and com-
ply with this information:
The airbags are supplemental restraint
devices designed to provide additional
protection; they are not a substitute for
safety belts. Wear your safety belt at all
times. The airbags are intentionally not trig-
