Correct sitting posture SeatsFor relaxed and fatigue-free driving you
should select a sitting position that
reflects your personal requirements.
Correct posture combines with safety
belts and airbags to enhance 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
attention to the following section.
For supplementary information on
transporting children, refer to page 52. Sitting correctly with airbags
Always maintain an adequate
distance between yourself and the
airbags. Always hold the steering wheel
by the rim to keep any chance of injury
to hands or arms to an absolute
minimum should the airbag be
deployed. Never allow any objects,
individuals 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
information on airbags refer to page 49.
Safe 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 passenger's lap. 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. 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 periodically 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 it is
worn loosely. 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 abdominal
area.<
For information on using the safety
belts refer to page 45.
When adjusting your seat, always
observe the following precautions
Never try to adjust your seat while
operating the vehicle. The seat
could respond with unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident. Never
ride with the backrest reclined to an
extreme horizontal angle (important for
front passengers to remember). Keep
the backrest relatively upright to mini-
mize the risk of sliding under the safety
belt and sustaining injury in an acci-
dent.<

To adjust manuallyThe mirrors can also be adjusted manu-
ally:
Press the edge of the lens.
Storing mirror settings, refer to Seat
and mirror memory on page 46.
The mirror on the passenger's side
features a lens with a more convex
surface than the mirror installed on the
driver's side. When estimating the
distance between yourself and other
traffic, bear in mind that the objects
reflected in the mirror are closer than
they appear. This means that estimates
of the distance to following traffic
should not be regarded as precise. This
precaution also applies to the non-
spherical outer section of the lens. *
Both mirrors are automatically heated
when you turn the ignition key to posi-
tion 2.
Interior rearview mirror To reduce glare from vehicles behind
you when you are driving at night, tilt
the lens by turning the button.

To ensure that the mirror continues to
operate efficiently, ensure that the
photocells remain clear and unob-
structed. One photocell is integrated in
the mirror's lens (arrow), while the other
is located at an offset position on the
rear of the mirror. Refrain from
attaching stickers to the windshield in

passenger sides (front and rear
*)
Protective effectThe front airbags supplement the three-
point safety belts by providing addi-
tional protection, in the event of a
severe frontal collision in which the
protection afforded by the belts alone
may no longer be sufficient. The Head
Protection System and side airbags
help provide protection 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.
For information on the correct sitting
posture, refer to page 41.Indicator lamp
The indicator lamp indicates the
operational status of the airbag
system from ignition key posi-
tion 1.
System operational:
>The indicator lamp comes on briefly
when you turn the ignition key to
position 1 or 2.
System malfunction:
>The indicator lamp fails to go out
after the engine has been started, or
comes on again during normal
driving.
Please respond to any malfunctions in
the system by immediately having it
inspected at your BMW center; other-
wise the airbag could fail to respond to
an accident in which both the angle and
the severity of the impact would
normally trigger airbag deployment.

Airbags
The side airbags in the rear
passenger area
* of your vehicle
may already have been deactivated,
either at the time of manufacture or by a
BMW center. You may have them acti-
vated if you desire to do so. Please
contact your BMW center for additional
information.<
The airbags do not deploy in
response to minor collisions, rear
impacts and certain kinds of vehicle
rollover.<
For your safety, comply with the
following instructions for the
airbags. If you do not, the airbags may
not be able to provide their maximum
protection. All passengers in the vehicle
should be aware of and comply with
these directions:
The airbags are supplemental restraint
devices designed to provide extra
protection; 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
vehicle roll-over, or collisions from the
rear. In these instances, the safety belt
provides optimal protection.
Airbags are located under cover panels
in the steering wheel, in the dashboard,
in the side trim panels in the front and
rear
*, in the roof panels, and in the
sides of the inside roof lining.
Adjust your seat to a position that
provides maximum distance between
you and the steering wheel, the instru-
ment panel and the door while still
allowing comfortable and safe access
to all vehicle controls.
To avoid sustaining hand and arm inju-
ries, always grasp the steering wheel
on the rim with the hands at the 9 and
3 o'clock positions. Do not place your
hands on the center pad.
Never allow any objects to obstruct the
area between the airbag and an occu-
pant.
Do not use the cover panel above the
passenger-side airbag as a storage
area.
Do not apply adhesive materials to the
cover panels of the airbags, cover them
or modify them in any other way.
Do not install a rear-facing child-
restraint system in the front passenger
seat of this vehicle.
Children under 13 years of age and less
than 5 ft (150 cm) tall should ride only in
the rear seat.
Infants or small children should never
be held on the lap of a passenger.
If your vehicle is equipped with side airbags in the rear passenger area
*, be
sure that child restraints are mounted
correctly with the greatest-possible
distance between them and the airbags
in the side trim panels. Do not allow
children to lean out of the child's seat in
the direction of the side trim panels. If
they do so, serious injuries can occur if
the airbag is triggered.<
At all times, occupants should sit
upright and be properly restrained
(infants and small children in appro-
priate child-restraint systems; larger
children and adults using the safety
belts). Never let an occupant's head
rest near or on a side airbag because
the inflating airbag could cause a
serious or fatal injury. Please note that
the word Airbag imprinted on the door
trim panel indicates the airbag's loca-
tion.
Accident research shows that the
safest place for children in an
automobile is in the rear seat. However,
a child sitting in the rear seat and not
properly restrained may place his or her
head on or near the airbag, if so
equipped. For example, a child Ñ even
though belted Ñ may fall asleep with his
or her head against the side airbag. It
may be difficult for a driver to ensure
