Transporting children safelyCommercially available child seats
complying with the legal standard are
designed to be secured with a lap belt
or with the lap belt portion of a combi-
nation 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 (refer to the arrows in
the illustration) have been provided.
Depending on the location selected for
seating in the rear passenger area,
attach the tether strap to the corre-
sponding anchorage point to secure the
child restraint system. Remove the
cover first on the middle location.380us123
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 rearward-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.) would be within the
airbag's deployment range, you should
never mount such a device in the front
passenger seat, since the impact of the
airbag against the child restraint's back-
rest could lead to serious or fatal inju-
ries.
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
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 manufacturer 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
practice for securing child restraint
systems in motor vehicles.

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.
460de140
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.
390de319
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.

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.
While you are driving, the functional
status of the actuator motors (for the
windshield wipers, power windows,
seats, sliding/tilt sunroof, etc.) is
constantly analyzed by current
measurements in their relays.460de177
In the same manner, the electrical
resistance of the airbag ignition genera-
tors and all of the remaining airbag
components is measured at all times.
Any fault in this system would be
detected immediately by a current fluc-
tuation that would necessarily accom-
pany 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 ensures that the defrost func-
tion is always available even if a
malfunction in the air conditioner
system/automatic climate control
should occur while the vehicle is
parked overnight, for instance.
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 will hear the sounds of the air flaps
as the air conditioning system/auto-
matic climate control carry out their
self-diagnostic functions after the igni-
tion has been turned off. All of the other
self-diagnostics functions operate
silently in the background.
Any possible faults detected during
these self-diagnostics can be read out
by your BMW center during the next
regularly-scheduled maintenance and
corrected with a minimum of time.
