For your own safety

Use unleaded gasoline only. Fuels
containing up to and including
10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight (i.e. 15 %
MTBE or 3 % methanol plus an equiva-
lent amount of co-solvent) will not void
the applicable warranties respecting
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
problems which you suspect could be
related to the fuel you are using, we
recommend 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
optimum 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,
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.
Do not use a key or the remote control
to lock the doors or the luggage
compartment with anyone inside the
vehicle. See Owner's Manual for more
details.

Maintenance, replacement, or
repair of the emission control
devices and systems may be performed
by any automotive repair establishment
or individual using any certified auto-
motive part.

Air conditionerDraft-free ventilation You can adjust the air outlets for the
upper body area to select the optimum
air flow 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 air flow with levers 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 166.

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 combined filter during
the regularly scheduled maintenance. A
substantial reduction in air supply indi-
cates that the filter must be replaced
before normal maintenance.
For further information about filter
replacement, refer to page 166.

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:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may 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 on the road
if it is deeper than 1 foot (30 cm), and
then only at walking speed. Otherwise,
the vehicle's engine, the electrical
systems and the transmission may be
damaged.
Rear window shelf:
Never use it to store heavy or hard
objects, otherwise, occupants could
be injured if the vehicle is braked hard.
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, they could cause personal injury
during braking or evasive maneuvers. exhaust emissions.
It 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 to 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 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 being analyzed by electrical
measurements in the relays.462us038
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 way you can be assured that
the defrost function is always available,
even if, for example, a defect crops up
in the air conditioner/automatic climate
control during the night while the
engine has been turned off.
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
positions 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 conditioner/automatic climate
control carries out its self-diagnostic
functions after the ignition has been
shut off. All of the other self-diagnostics
functions operate silently in the back-
ground.
Any possible faults detected during
these self-diagnostics can be read out
and corrected by your BMW center
during the next regularly scheduled
maintenance.
