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- ment
Replace 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

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.

Drive belts
The alternator, power steering pump, and
air conditioner compressor depend on
drive belts. Satisfactory performance re-
quires that belt tension be correct. „2.5-liter models
1) Power steering pump pulley
2) Air conditioner compressor pulley
3) Crank pulley in (mm)
To check belt tensi on, place a straight-
edge (ruler) across two adjacent pulleys
and apply a force of 22 lbs (98 N, 10 kg)
midway between the pulleys by using a
spring scale. Belt deflection should be the
amount specified. „ 3.0-liter models
It is unnecessary to check belt tension pe-
riodically because your engine is
equipped with an autom atic belt tension
adjuster. However, replacement of the
belt should be done according to the
maintenance schedule in the “Warranty
and Maintenance Booklet”. Consult your
SUBARU dealer for replacement.
If a belt is loose, cr acked, or worn, contact
your SUBARU dealer.Manual transmission oil „ Checking the oil level

Brake booster
If the brake booster does not operate as
described in the following, have it checked
by your SUBARU dealer.
1. With the engine off, depress the brake
pedal several times, applying the same
pedal force each time. The distance the
pedal travels should not vary.
2. With the brake pedal depressed, start
the engine. The pedal should move slight-
ly down to the floor.
3. With the brake pedal depressed, stop
the engine and keep the pedal depressed
for 30 seconds. The pedal height should
not change.
4. Start the engine again and run for ap-
proximately one minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake boost-
er operates properly if the pedal stroke de-
creases with each depression.Brake pedal
Check the brake pedal free play and re-
serve distance according to the mainte-
nance schedule in the “Warranty and
Maintenance Booklet”. „Checking the brake pedal free
play
1) 0.02 – 0.08 in (0.5 – 2.0 mm)
Stop the engine and firmly depress the
brake pedal several times. Lightly pull the
brake pedal up with one finger to check
the free play with a force of less than 2 lbs
(10 N, 1 kg).
If the free play is not within proper specifi-
cation, contact your SUBARU dealer. „
Checking the brake pedal re-
serve distance
1) More than 2.56 in (65 mm)
Depress the pedal with a force of approxi-
mately 66 lbs (294 N, 30 kg) and measure
the distance between the upper surface of
the pedal pad and the floor.
When the measurement is smaller than
the specification, or when the pedal does
not operate smoothly, contact with your
SUBARU dealer.

Clutch pedal (Manual trans-
mission vehicles)
Check the clutch pedal free play and re-
serve distance according to the mainte-
nance schedule in the “Warranty and
Maintenance Booklet”. „
Checking the clutch function
Check the clutch engagement and disen-
gagement.
1. With the engine idling, check that there
are no abnormal noises when the clutch
pedal is depressed, and that shifting into
1st or reverse feels smooth.
2. Start the vehicle by releasing the pedal
slowly to check that the engine and trans-
mission smoothly couple without any sign
of slippage. „
Checking the clutch pedal
free play
1) 0.16 – 0.51 in (4.0 – 13.0 mm)
Lightly press the clutch pedal down with
your finger until you feel resistance, and
check the free play.
If the free play is not within proper specifi-
cation, contact your SUBARU dealer. Replacement of brake pad and lining
The right front disc brake and the right rear
disc brake have audible wear indicators
on the brake pads. If the brake pads wear
close to their service limit, the wear indica- tor makes a very audible scraping noise
when the brake pedal is applied.
If you hear this scraping noise each time

If you continue to drive despite the
scraping noise from the audible
brake pad wear indicator, it will re-
sult in the need for costly brake ro-
tor repair or replacement.
