Transporting children safelyCommercially available child restraint
systems are designed to be secured
with a lap belt or with the lap belt
portion of a combination lap/shoulder
belt. Improperly or inadequately
installed restraint systems can increase
the risk of injury to children. Always
read and follow the instructions that
come with the system.
If you use a child restraint system with a
tether strap, three additional tether
anchorage points have been provided
(refer to the arrows in the illustration).
Depending on the location selected for
seating in the rear passenger area,
attach the strap hook to the corre-
sponding anchorage point to secure the
child restraint system. Remove the
cover first on the middle location.
If the respective seating position is
fitted with a headrest, lift the headrest
and pass the tether strap between the
headrest and the seat back.
Adjust the tether strap according to the
child restraint manufacturer's instruc-
tions.
Before installing any child restraint
device or child seat, please read
the following:
Never install a rear-facing child restraint
system in the front passenger seat of
this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rear-facing child restraint
system (of the kind designed for infants
under 1 year and 20 lbs/kg) would be
within the airbagÕs deployment range,
you should never mount such a device
in the front passenger seat, since the
impact of the airbag against the child
restraintÕs backrest could lead to
serious 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 instrument panel as possible.
This important precaution is intended to
maximize the distance between the
airbag 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. Never install a rear-facing
child restraint system in the front
passenger seat. We strongly urge you
to carefully read and comply with the
instructions for installation and use
provided by the child restraint's manu-
facturer whenever you use such a
device.
Be sure 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.

Airbags Vehicle storageImportant safety notices
Don't remove the airbag restraint
system's gas generator. Have
testing and service procedures per-
formed by specially-qualified techni-
cians only. In the event of any faults, if
the airbag stops working, or in the
event of function-oriented use (deploy-
ment) of the airbag restraint system,
entrust your BMW center alone with
repair or disassembly.
No modifications may be made to either
the wiring or to individual components.
These include the padded steering
wheel hub, the instrument 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 components, cover
or modify them in any way. Do not
remove or dismantle the steering wheel
yourself.
To ensure compliance with official
safety regulations, entrust disposal of
airbag generators to a BMW center.
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.<
Consult your BMW center regarding
special procedures if you intend to
store the vehicle for more than three
months.

Deceleration sensors continuously
monitor the physical forces acting upon
the vehicle. If there is a deceleration
because of a head-on collision in which
the protection normally afforded by the
safety belts is no longer sufficient by
itself, then the gas generators for the
front airbags will be simultaneously
ignited on both the driver and
passenger sides. 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 impact, the front
head and side airbags or rear side
airbags
* will deploy if necessary on the
side where the impact occurs.
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.
The gas required to inflate the airbags
is not dangerous, and it dissipates
together with the associated smoke.
The gas required to inflate the airbags
is not dangerous, and the smoke asso-
ciated with it dissipates.
The entire process is completed within
fractions of a second. The AM frequency bands (medium-
wave, long-wave and short-wave) make
it possible to receive stations from a
great distance, because the broadcast
signals travel not only along the ground
as surface waves, but also as atmo-
spheric waves that are reflected from
the ionosphere.
Frequency-modulation (FM) provides
substantially better sound quality than
on the. However, because FM trans-
missions rely on line-of-sight broadcast
waves, their effective reception range is
limited.

Self-diagnostics All of the important electrical and elec-
tronic systems in the vehicle are tested
regularly and automatically Ð the driver
does not have to perform any extra
operations or adjustments.
The indicator lamps also come on
briefly after the ignition has been turned
on.
In the same manner, the electrical
resistance of the airbag ignition genera-
tors and all of the remaining airbag
components are constantly being
measured. Any fault in this system
would be detected immediately by a
current fluctuation that would neces-
sarily accompany it. The fault would be
indicated immediately by the airbag
warning lamp.
Even after you shut off the engine, the
overall functional status of your vehicle
is monitored. For example, all of the
flaps of the heating and ventilation
system travel to the nearest limit posi-
tion. This action ensures that the
defrost function will be preserved,
regardless of the circumstances, even
if, for example, a malfunction in the
heating or ventilation system should
occur during the night while the vehicle
is parked.
A calibration cycle runs every tenth time
the engine is shut off. During this cycle,
the actuator motors of all the heating
and ventilation flaps travel to their limit
stops in both directions. The limit posi-
tions and the return travel paths are
checked in this manner in order to
ensure that appropriate adjustments for
the operating elements can be made at
any time.
You can hear the vent flaps of the
heating or ventilation system
performing their self-diagnostics
routine after turning off the ignition. All
of the other self-diagnostics functions
operate silently in the background.Any possible faults detected during
these self-diagnostics can be read out
and corrected by your BMW center
during the next regularly scheduled
maintenance.
