back in the seat with your back pressed
firmly against the backrest.
Ideal sitting posture is achieved with
your head extending from your spine in
a straight line.
For long-distance driving, you may wish
to increase the backrest angle slightly
to reduce muscular tension. Please
remember that you should always
remain able grasp the entire periphery
of the steering wheel without straight-
ening your arms.c

The airbags are triggered by impacts
coming from the directions shown in
the illustration. Note that the supple-
mentary protection against lateral
impact is available only on vehicles
equipped with optional door-mounted
airbags.Indicator lamp in instrument
clusterSystem operational:
dThe indicator lamp comes on briefly.
System malfunction:
dThe indicator lamp fails to come on.dIndicator lamp lights up for approx.
4 seconds, goes out brießy and then
lights up again.
A system malfunction could prevent the
system from responding to an impact
occurring within its normal response
range.
Please have your authorized BMW
Retailer inspect and repair the system
as soon as possible.
a
For your own safety, please ob-
serve the following precautions con-
cerning airbags, as otherwise their
protective function may be impaired. We
also request that you make this informa-
tion available to your passengers, and
that you urge them to observe the in-
structions for safety belt use: the air-
bags are a supplemental restraint
device designed to provide extra pro-
tection; they are not a substitute for
safety belts. Wear your safety belt at all
times. The system does not respond to
minor collisions, if the vehicle rolls over,
or if the impact is at the rear of the vehi-
cle. In this situation, only the safety belt
protects you.
When adjusting your seat, select a posi-
tion that provides maximum distance
between you and the steering wheel, the instrument panel and the door while still
allowing comfortable and safe access to
all vehicle controls.
Always grip the steering wheel on its
rim with your hands at the 9 and 3 oÕclock
positions, otherwise hand and arm inju-
ries could occur when the airbag
inflates.
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 glue, cover or in any way alter
the padded covers on the steering
wheel, the instrument panel or the side
trim panels of the front doors.
Do not install a rear-facing child re-
straint device on the front passenger
seat. Children under 12 years of age
should only sit in the back.c
Even when all these guidelines are
observed, there is still a residual risk of
mild facial injuries occurring in isolated
instances of airbag actuation. The igni-
tion and inßation noise may induce a
mild temporary hearing loss in sensitive
individuals.
Airbag information is also located on
the sun visors.

The indicator lamp comes on from
ignition key position 1 to indicate
that the system is operational.

Notes on safetyNever attempt to remove the gas gener-
ator for the airbag passenger-restraint
system from the vehicle. Testing and
service procedures are to be performed
exclusively by qualified technicians. In
the event of malfunction, deactivation
or triggering (in response to an acci-
dent), always entrust repair and service
operations to your authorized BMW
Retailer.
Do not modify or tamper with either the
wiring or the individual components in
the airbag system; these include also
the padded covers on the steering
wheel, on the instrument panel or on
the side trim panels of the front doors.
Never apply adhesive materials to these
components and never cover or modify
them in any way. Do not remove or dis-
mantle the steering wheel.
The airbag generator can be disposed
of only by a BMW Retailer.
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.Insert the key in the slot in one of the
rear door latch mechanisms and turn
toward the outside: the door can now
be opened from the outside only.The rollover protection system is acti-
vated automatically in the event of an
accident or in a critical driving situation
(extreme tilting in the longitudinal or lat-
eral axis, loss of ground contact). The
protective bars located behind the rear
head restraints extend within a fraction
of a second.
In addition to the roll bar integrated in
the windshield frame, the rollover pro-
tection system helps provide all vehicle
occupants, and in particular the rear
passengers, with needed headroom.
b
When the hardtop
* is on, it is
advisable to use "soft" protective cov-
ers, in order to prevent damage to the
luggage compartment lid when the sys-
tem is activated. Please contact your
authorized BMW Retailer for additional
information.c
a
Always keep the space required by
the rollover protection system free of
obstacles.
In the case of minor, non-rollover acci-
dents, passengers are protected only by
the buckled safety belt and the belt ten-
sioner and, depending on the severity of
the accident, the airbag restraint sys-
tem.c
