2001 BMW 330XI SEDAN maintenance schedule

6n

For your own safety

Use unleaded gasoline only.
Fuels containing up to 10%
ethanol 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
temperature 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.

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,
compromise 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.

Air conditioner Draft-free ventilation You can adjust the blower controls for
the upper body area to select the
optimum airflow rates and directions for
your personal requirements:
Use rotary dials 1 to open and close the
air outlets through an infinitely-variable
range. You can adjust the direction of
the airflow with rotary dial 2.
Set the outlets so that the air flows past
you and is not directed straight at you.
Rotary dial 3 allows you to mix the air
from the outlets for your upper body by
warming or cooling the air as desired.460de040
Microfilter An activated-charcoal microfilter, which
traps incoming dust and pollen, has
been installed in your vehicle. Your
BMW center will replace it during regu-
larly scheduled maintenance. A
substantial reduction in air supply indi-
cates that the filter must be replaced
before normal maintenance.
For additional details on the filter
change, refer to page 171.

When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically. Refer to
page 71.
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
desired.460de040
Microfilter/Activated-charcoal
filterThe microfilter traps incoming dust and
pollen. The activated-charcoal filter
helps clean the incoming outside air of
gaseous pollutants. Your BMW center
will replace this combinated filter during
the regularly scheduled maintenance. A
substantial reduction in air supply indi-
cates that the filter must be replaced
before normal maintenance.
For additional information on the filter
change, refer to page 171.

Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but
consistent pedal pressure can lead to
high temperatures, brake wear, and
possibly to brake failure.
Aquaplaning:
Reduce your speed when you drive on
wet or slushy roads. If you do not, a
wedge of water can form between the
tires and the road surface. This
phenomenon is referred to as aqua-
planing or hydroplaning. It is character-
ized by a partial or complete loss of
contact between the tires and the road
surface. The ultimate results are loss of
steering and braking control.
Driving through water:
Do not drive through water that is
deeper than 1 foot (30 cm). If you must
drive through water accumulations up
to that depth, drive only at walking
speed. Driving at a faster speed could
cause damage to the engine, the elec-
trical systems and the transmission.
Package tray:
Never use the rear window shelf to
store heavy or bulky objects. If you do
so, such objects could pose the risk of
injury to vehicle occupants during
braking or evasive maneuvers or in a
crash.
Clothes hooks:
When suspending clothing from the
hooks, be sure that they will not
obstruct 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
evasive 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.

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.
