reduce HC, CO and NOx in exhaust gas-
es, thus providing cleaner exhaust.
To avoid damage to the catalytic convert-
er:
y Use only unleaded gasoline. Even a
small amount of leaded gasoline will dam-
age the catalytic converter.
y Never start the engine by pushing or
pulling the vehicle.
y Avoid racing the engine.
y Never turn off the ignition switch while
the vehicle is moving.
y Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer.
y Do not apply undercoating or rust pre-
vention treatment to the heat shield of cat-
alytic converter and the exhaust system. Periodic inspections To keep your vehicle in the best condition
at all times, always have the recommend-
ed maintenance services listed in the
maintenance schedule in the “Warranty
and Maintenance Booklet” performed at
the specified time or mileage intervals.
Driving in fo reign countries When planning to use your vehicle in an-
other country:
y Confirm the availability of the correct fu-
el. (Refer to the “Fuel requirements” sec-
tion in chapter 7.)
y Comply with all regulations and require-
ments of each country.

Maintenance schedule The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the “Warranty and Mainte-
nance Booklet”.
For details of your maintenance schedule,
read the separate “Warranty and Mainte-
nance Booklet”.
Maintenance precautions When maintenance and service are re-
quired, it is recommended that all work be
done by an authorized SUBARU dealer.
If you perform maintenance and service
by yourself, you should familiarize your-
self with the information provided in this
section on general maintenance and ser-
vice for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
y Testing of an All-Wheel Drive ve-
hicle must NEVER be performed
on a single two-wheel dynamome-
ter or similar apparatus. Attempt-
ing to do so will result in transmis-
sion damage and in uncontrolled
vehicle movement and may cause
an accident or injuries to persons
nearby.
y Always select a safe area when
performing maintenance on your
vehicle. y Always be very careful to avoid in-
jury when working on the vehicle.
Remember that some of the mate-
rials in the vehicle may be hazard-
ous if improperly used or handled,
for example, battery acid.
y Your vehicle should only be ser-
viced by persons fully competent
to do so. Serious personal injury
may result to persons not experi-
enced in servicing vehicles.
y Always use the proper tools and
make certain that they are well
maintained.
y Never get under the vehicle sup-
ported only by a jack. Always use
a safety stands to support the ve-
hicle.
y Never keep the engine running in
a poorly ventilated area, such as a
garage or other closed areas.
y Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire.
y Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only by
your SUBARU dealer.

11 - 1 0 Maintenance and service
If you check the oil level just after stopping
the engine, wait a few minutes for the oil to
drain back into the oil pan before checking
the level.
To prevent overfilling the engine oil, do not
add any additional oil above the upper lev-
el when the engine is cold.
In 2.5-liter-engine models, the dipstick has
a notch above the upper level.
Just after driving or while the engine is
warm, the engine oil level reading may be
in a range between the upper level and
the notch mark. This is caused by thermal
expansion of the engine oil.
„ Changing the oil and oil filterChange the oil and oil filter according to
the maintenance schedule in the “Warran-
ty and Maintenance Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in the
maintenance schedule when driving on
dusty roads, when short trips are frequent-
ly made, or when driving in extremely cold
whether.
1. Warm up the engine by letting the en-
gine idle for approximately 10 minutes to
ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine. 3. Remove the oil filler cap.
2.5-liter models
3.0-liter models
4. Drain out the engine oil by removing the drain plug while the engine is still
warm. The used oil should be drained into
an appropriate container and disposed of
properly.
5. Wipe the seating surface of the drain
plug with a clean cloth and tighten it se-
curely with a new sealing washer after the
oil has completely drained out.

tem conditioner whenever the coolant is
replaced.

uine Subaru cooling system conditioner
using the following procedures according
to the maintenance schedule in the “War-
ranty and Maintenance Booklet”.
1. Remove the under cover.

2. Place a proper container under the
drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the
coolant from the radiator. Then drain the
coolant from the reserve tank. Tighten the
drain plug securely. 4. Install the under cover.

Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed. B00423

– CONTINUED –Air cleaner element
The air cleaner element functions as a fil-
ter screen. When the element is perforat-
ed or removed, engine wear will be exces-
sive and engine life shortened.
The air cleaner element is a dry type. It is
unnecessary to clean or wash the ele-
ment.
„ Replacing the air cleaner ele-
mentReplace the air cleaner element according
to the maintenance schedule in the “War-
ranty and Maintenance Booklet”. Under
extremely dusty conditions, replace it
more frequently. It is recommended that
you always use genuine SUBARU parts. T Non-turbo models 0
1) Connector
2) Duct
3) Clamp
1. Unplug the connector that is attached
to the top of the air cleaner case.
2. Remove the hose that is located at the
bottom of the side surface of the air clean-
er case.
3. Undo the screw and pull the air duct
out of the air cleaner case.
4. Unsnap the two clamps holding the air
cleaner case cover. 5. Open the air cleaner case cover and
remove the air cleaner element.
6. Clean the inside of the air cleaner cov-
er and case with a damp cloth and install
a new air cleaner element.Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters in-
take air but also stops flames if the
engine backfires. If the air cleaner
element is not installed when the en-
gine backfires, you could be burned. 13
