The oil quantity indicated above is only a
guideline. The necessary quantity of oil
depends on the quantity of oil that has
been drained. The quantity of drained oil
differs slightly depending on the tempera-
ture of the oil and the time the oil is left
flowing out. After pouring oil into the en-
gine, therefore, you must use the dipstick
to confirm that the level is correct.
13.Start the engine and make sure that no
oil leaks appear around the filter’s rubber
seal.
14.Run the engine until it reaches the nor-
mal operating temperature. Then stop the
engine and wait a few minutes to allow the
oil drain back. Check the oil level again
and if necessary, add more engine oil.„Recommended grade and
viscosityOil grade:
ILSAC GF-4, which can be identified
with the ILSAC certification mark
(Starburst mark)
or API classification SM with the
words “ENERGY CONSERVING”
These recommended oil grades can be
identified by looking for either or both of
the following marks displayed on the oil
container.
API Service label
1) Indicates the oil quality by API designa-tions
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving ca- pabilities ILSAC Certification Mark (Starburst
Mark)
In choosing an oil, you want the proper
quality and viscosity, as well as one that
will add to fuel economy. The following ta-
ble lists the recommended viscosities and
applicable temperatures.
When adding oil, different brands may be
used together as long as they are the
same API classification and SAE viscosity
as those recommended by SUBARU.

Maintenance and service
„Cooling fan, hose and con-
nectionsYour vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be de-
fective. Check the fuse and replace it if
necessary. If the fuse is not blown, have
the cooling system checked by your
SUBARU dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness.
„Engine coolantT Checking the coolant level1) “FULL” level mark
2) “LOW” level markCheck the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the
“LOW” level mark, add coolant up to the
“FULL” level mark. If the reserve tank is
empty, remove the radiator cap and refill
as required. 3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.

y Be careful not to spill engine cool-
ant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on the
exhaust pipe, be sure to wipe it
off.
y Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.

Automatic transmission fluid„ Checking the fluid levelThe automatic transmission fluid expands
largely as its temperature rises; the fluid
level differs according to fluid tempera-
ture. Therefore, there are two different
scales for checking the level of hot fluid
and cold fluid on the dipstick.
Though the fluid level can be checked
without warming up the fluid on the
“COLD” range, we recommend checking
the fluid level when the fluid is at operating
temperature.
T Checking the fluid level when the
fluid is hot
Check the fluid level monthly.
1. Drive the vehicle several miles to raise
the temperature of the transmission fluid
up to normal operating temperature; 154
to 176 °F (70 to 80 °C) is normal.
2. Park the vehicle on a level surface and
set the parking brake.
3. First shift the selector lever in each po-
sition. Then shift it in the “P” position, and
run the engine at idling speed.
Be careful not to spill manual trans-
mission oil when adding it. If oil
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or a
fire. If oil gets on the exhaust pipe,
be sure to wipe it off.

Power steering fluid„Checking the fluid level1) Reservoir tankThe power steering fluid expands greatly
as its temperature rises; the fluid level dif-
fers according to fluid temperature. There-
fore, the reservoir tank has two different
checking ranges for hot and cold fluids.
Check the power steering fluid level
monthly.
1. Park the vehicle on a level surface, and
stop the engine.
1) Specified range2. Check the fluid level of the reservoir
tank.
When the fluid is hot after the vehicle has
been run: Check that the oil level is be-
tween “HOT MIN” and “HOT MAX” on the
surface of the reservoir tank.
When the fluid is cool before the vehicle is
run: Check that the oil level is between
“COLD MIN” and “COLD MAX” on the sur-
face of the reservoir tank.
3. If the fluid level is lower than the appli-
cable “MIN” line, add the recommended
fluid as necessary to bring the level be-
tween the “MIN” and “MAX” line.
If the fluid level is extreme low, it may indi-
cate possible leakage. Consult your
SUBARU dealer for an inspection.

Brake boosterIf 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 pedalCheck 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
play1) 0.02 – 0.08 in (0.5 – 2.0 mm)Stop the engine and firmly depress the
brake pedal several times. Lightly press
the brake pedal down 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.
y
Never splash the clutch fluid over
painted surfaces or rubber parts.
Alcohol contained in the clutch
fluid may damage them.
y Be careful not to spill clutch fluid
when adding it. If clutch fluid
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If clutch fluid gets on the ex-
haust pipe, be sure to wipe it off.
Avoid mixing DOT 3 and DOT 4
brake fluids even if they are of the
same brand.

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.

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.
