Before install-
ing any child re-
straint device or
child seat, please
read the follow-
ing:
Never install a rearward-facing child
restraint system in the front passenger
seat of this car.
Your car is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rear-facing child restraint sys-
tem (of the kind designed for infants
under 1 year and 20 lbs.) would be
within the airbag's deployment range,
you should never mount such a device
in the front passenger seat, as the
impact of the airbag against the child
restraint's backrest could lead to seri-
ous or fatal injuries.
If it is necessary for a child (not an
infant) to ride in the front seat, certain precautions should be taken. First,
move the passenger seat as far away
from the dashboard as possible. This
important precaution is intended to
maximize the distance between the air-
bag and the child. Older children should
be tightly secured with the safety belt.
Younger children should be secured in
an appropriate forward-facing child
restraint system that has first been
properly secured with a safety belt.
We strongly urge you to carefully read
and observe the instructions for instal-
lation and use provided by the child re-
straint's manufacturer whenever you
use such a device.
Always ensure that all occupants (of
all ages) remain properly and securely
restrained at all times.c
All rear seating positions in your vehicle
meet the recommendations of SAE
J1819, an industry recommended prac-
tice for securing child restraint systems
in motor vehicles.1 Front airbag system, consisting of
driver and passenger airbag
2 Side airbags
*
Protective effectThe front airbags provide additional
protection for the front-seat occupants
in the event of a severe frontal collision
in which the protection afforded by the
safety belts alone would no longer be
sufficient. The side airbags help protect
the front seat occupants in a severe
side impact.360de305

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.
p
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

Deceleration sensors continuously
monitor the physical forces acting upon
the vehicle. If a frontal impact results in
deceleration, for which the protection
afforded by safety belts no longer suf-
fices, the gas generators of the driver's
and the passenger's airbags ignite
simultaneously. The passenger's air-
bag is activated only when a special
sensor indicates that the front passen-
ger's seat is occupied.
In the event of a severe side impact the
side airbag
* is activated on the side on
which the impact occurred.
The airbags, which are under the cover
of the steering wheel, in the instrument
panel or the side trim panels of the front
doors, are deployed and inflated by the
gas within a few milliseconds. In the
process they tear or push apart the pro-grammed separation points in their
upholstered covers.
Because the inflation process must be
virtually instantaneous, it is necessarily
accompanied by a certain amount of
ignition and inflation noise. The gas
which the system employs to inflate the
airbag is not dangerous, and the asso-
ciated smoke is quickly dissipated.
The entire process is completed within
one twentieth of a second.Automatic Stability Control plus Trac-
tion helps maintain stable and con-
trolled vehicle response by inhibiting
slip at the drive wheels.
The system employs special sensors to
monitor wheelspeed and relay the data
to the system's electronic control unit,
which uses this information to calculate
slip rates at the individual wheels.
Depending on the driving situation, two
forms of remedial action can then be
taken by the system: it reacts to slip-
page caused by large amounts of
excess torque by instructing the engine
management system to reduce power
output. As a supplementary measure,
the system will also respond to an
especially pronounced tendency to-
ward traction loss at either of the drive
wheels with automatic individual appli-
cation of the affected wheel's brakes.
This achieves a locking action compa-
rable with a controlled limited-slip dif-
ferential. This brake action is active up
to 25 mph (40 km/h). From 25 mph
(40 km/h) upward, a diminished brake
action improves the traction up to
60 mph (100 km/h).
