2000 BMW 323i SEDAN maintenance schedule

6n

For your own safety

Use unleaded gasoline only.
Fuels containing up to 10% etha-
nol or other oxygenates with up to 2.8%
oxygen by weight (i.e. 15% MTBE or
3% methanol plus an equivalent
amount of co-solvent) will not void the
applicable warranties with respect to
defects in materials or workmanship.
Field experience has indicated signifi-
cant differences in fuel quality (volatility,
composition, additives, for example)
among gasolines offered for sale in the
United States and Canada. The use of
poor-quality fuels may result in drive-
ability, starting and stalling problems,
especially under certain environmental
conditions, such as high ambient tem-
perature and high altitude.
Should you encounter driveability prob-
lems that you suspect could be related
to the fuel you are using, we recom-
mend that you respond by switching
to a recognized high-quality brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Follow the relevant safety rules when
you are handling gasoline.

Important safety information!
For your own safety, use genuine
parts and accessories approved by
BMW.
When you purchase accessories tested
and approved by BMW and Original
BMW Parts, you simultaneously acquire
the assurance that they have been thor-
oughly tested by BMW to ensure opti-
mum performance when installed on
your vehicle.
BMW warrants these parts to be free
from defects in material and workman-
ship.
BMW will not accept any liability for
damage resulting from installation of
parts and accessories not approved by
BMW.
BMW cannot test every product from
other manufacturers to verify if it can be
used on a BMW safely and without risk
to either the vehicle, its operation, or its
occupants.
Original BMW Parts, BMW Accessories
and other products approved by BMW,
together with professional advice on
using these items, are available from all
BMW centers.

Installation and operation of non-BMW
approved accessories such as alarms,
radios, amplifiers, radar detectors,
wheels, suspension components, brake
dust shields, telephones (including
operation of any portable cellular phone
from within the vehicle without using an
externally mounted antenna) or trans-
ceiver equipment (such as C.B., walkie-
talkie, ham radio or similar) may cause
extensive damage to the vehicle, com-
promise its safety, interfere with the
vehicle's electrical system or affect the
validity of the BMW Limited Warranty.
See your BMW center for additional
information.
Do not use a key or remote control to
lock the doors or luggage compartment
with anyone inside the car. See
page 34 for more details.
"Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any
automotive repair establishment or indi-
vidual using any certified automotive
part."

Automatic climate controlRear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically. Refer to
page 70.
Draft-free ventilation Set the ventilation outlets for your upper
body area so that it is comfortable for
you:
Use rotary dials (1) to open and close
the air outlets through an infinitely-vari-
able range. You can adjust the direction
of the airflow with the levers (2).
Set the outlets so that the air flows past
you and is not directed straight at you.
The rotary dial (3) allows you to mix the
air from the outlets for your upper body
by warming or cooling the air as de-
sired.460de040
Microfilter, activated-charcoal
filterA microfilter removes dust and pollen
from the incoming outside air. The acti-
vated-charcoal filter provides additional
protection by filtering gaseous pollut-
ants from the outside air. Your BMW
center replaces the combined filter as a
standard part of your scheduled main-
tenance. A substantial reduction in air
supply indicates that the filter must be
replaced before normal maintenance.
For additional details on the filter
change, refer to page 155.

Clothes hooks:
When suspending clothing from the
hooks, be sure that they will not ob-
struct the driver's vision. Do not hang
heavy objects on the hooks. If you do
so, such objects could pose the risk of
personal injury during braking or eva-
sive maneuvers. exhaust emissions, and is designed for
use with unleaded fuel only.
Even minute quantities of lead would be
enough to permanently damage both
the catalytic converter and the system
oxygen sensor.
To ensure efficient, trouble-free engine
operation and avoid potential damage:
>Be sure to comply with the scheduled
maintenance requirements.
>Fill the fuel tank well before it is
empty.
>Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, unburned residual
fuel in the catalytic converter could
ignite and cause damage. It is better
to jump-start the vehicle with outside
assistance.
>Avoid other situations in which the
fuel is not burned, or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never allow the engine to run with
any of the spark plug cables discon-
nected.Be sure to comply with the in-
structions above to prevent un-
burned fuel from reaching the catalytic
convertor. If you do not, the catalytic
converter could respond by overheat-
ing, leading to serious damage.
Extreme temperatures occur at the cat-
alytic converter on this and every cata-
lyst-equipped vehicle. Heat shields are
installed adjacent to some sections of
the exhaust system. Never remove
these shields; do not apply undercoat-
ing to their surfaces. When driving,
standing at idle, and parking the vehi-
cle, take extra care to avoid contact be-
tween the exhaust system and flamma-
ble materials (grass, hay, leaves, etc.).
Such contact could lead to a fire, re-
sulting in serious personal injury and
property damage.

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, sunroof, etc.) is constantly ana-
lyzed by current measurements in their
relays.460de177
In the same manner, the electrical re-
sistance 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 de-
tected immediately by a current fluctua-
tion that would necessarily accompany
it. The fault would be indicated immedi-
ately 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 sys-
tem travel to the nearest limit position.
This action ensures that the system will
be able to provide defrosting, regard-
less of other circumstances (if a mal-
function in the heating or ventilation
system should occur during the night
while the vehicle is parked, for in-
stance).
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 en-
sure that appropriate adjustments for
the operating elements can be made at
any time.You will hear the sounds of the air flaps
as the heater/ventilation system carries
out its self-diagnostic functions after the
ignition is shut off. All of the other self-
diagnostics functions operate silently in
the background.
Any 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.
