AirbagsDo 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
children less than 5 feet (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 and provided with the
greatest-possible distance between 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. 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 automo-
bile 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 diffi-
cult for a driver to ensure that children
in the rear seat will remain properly
positioned at all times and not place
their heads on or near the side airbag.
Therefore, we recommend that the rear
seat side airbags, if so equipped, be
deactivated if children will travel in the
rear seat.
The rear seat side airbags may
already have been deactivated, either
at the time of manufacture or by a
BMW center. Labels in the rear door
opening should indicate the status of
your rear seat side airbags. If you are
uncertain of their status, or wish to have
the airbags activated or deactivated,
please contact your BMW center.<
Even when all these guidelines are
observed, there is still a small residual
risk of injuries to the face, hands and
arms occurring from airbag deployment
in isolated instances. The ignition and
inflation noise may induce a mild
temporary hearing loss in sensitive indi-
viduals.
For additional information concerning
the airbag system, refer to pages 152
and 179.

Airbags For protection against dampness or
moisture, treat the leather with a BMW
impregnating agent.
We recommend that you perform this
procedure twice a year on leather
exposed to normal use.
Spills should be wiped up immediately.
Remove grease and oil stains without
rubbing, but rather by dabbing with
spot remover.
If the upholstery will be exposed to
intense sunlight, or if the vehicle is to
be stored for an extended period, cover
all leather surfaces to prevent fading (or
better yet, cover the windows).
Use cleaning and car-care
products that you can obtain at
your BMW center.<
Cleaning agents can contain
substances that are dangerous or
that pose health risks. For this reason,
always comply with the warnings and
danger notices on the packaging.
Open the doors or windows on your
vehicle when cleaning the interior.
Never clean your vehicle with solvents
or other materials not specifically
intended for this purpose.<

Important safety notices
Don't remove the airbag restraint
system's gas generator. Testing
and servicing must be performed by
trained technicians only. In the event of
a malfunction, deactivation, or triggered
actuation (as a response to an accident)
of the airbag restraint system, consult
your BMW center for repairs or service
operations.

Do not modify or tamper with either the
wiring or the individual components in
the airbag system. These include the
padded steering wheel hub, the instru-
ment panel, the side trim panels of the
front or rear doors and the roof pillars or
the sides of the headliner. Do not apply
adhesive materials to these compo-
nents 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, have a BMW center
dispose of airbag generators.
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. special procedures if you intend to
store the vehicle for more than three
months.

Deceleration sensors continuously
monitor the acceleration forces acting
upon the vehicle. If, as the result of a
frontal collision, a deceleration is
reached at which the protection of the
safety belts alone is no longer
adequate, the gas generators of the
driver and passenger-front airbags are
ignited simultaneously. However, the
passenger-side airbag is only triggered
if an additional sensor has recognized
that the passenger seat is occupied.
In the event of a side collision, the head
protection and side airbags in the front
and rear
* are triggered if necessary.

The airbags located under the marked
covers inflate and unfold in a matter of
a few milliseconds. In this process, they
tear through the designed separation
points of the upholstered covers or
press them out.
Because the inflation process must be
virtually instantaneous, it is necessarily
accompanied by a certain amount of
ignition and inflation noise. The gas
required to inflate the airbags is not
dangerous, and the smoke associated
with it dissipates.
The entire process is completed within
fractions of a second.
