3. Be sure the level gauge is correctly
inserted until it stops. For turbo models,
the graphic symbol “
”on the top of the
gauge should be positioned as shown in
the illustration.
4. Pull out the oil level gauge again.5. Non-turbo models:
Check the oil levels on both sides of the
level gauge. The engine oil level must be
judged by the lowest of the two levels. If
the oil level is below the low level mark,
add oil so that the full level is reached. Turbo models:
Check the oil level on the gauge. If the oil
level is below the low level mark, add oil
so that the full level is reached.
CAUTION
. For non-turbo models, be careful
not to touch the engine oil filter
when removing the oil filler cap.
Doing so may result in a burn, a
pinched finger, or may cause
some other injury.
. Use only engine oil with the
recommended grade and vis-
cosity.
. Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level iscorrect.

NOTE .Just after driving or while the engine
is warm, the engine oil level reading
may be in a range between the full level
and the notch mark (turbo models).
This is caused by thermal expansion of
the engine oil.. To prevent overfilling the engine oil,
do not add any additional oil above the
full level when the engine is cold. & Changing the oil and oil filter
CAUTION
. If you change your own oil, be
sure to drain all the oil from the
filter before disposal.
. Do not dispose of used engine oil
by placing it in the trash, or by
pouring it onto the ground, into
sewers, or into any body of water.
Check with your local govern-
ment office for the proper dis-
posal options available to you.
Change the oil and oil filter according to
the maintenance schedule in the “War-
ranty 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
frequently made, or when driving in
extremely cold weather.
1. Warm up the engine by letting the
engine 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.
Turbo models
Non-turbo 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.
WARNING
Be careful not to burn yourself with
hot engine oil.
5. Wipe the seating surface of the drain
plug with a clean cloth and tighten it
securely with a new sealing washer after
the oil has completely drained out.
6. Remove the under cover (turbo mod- els). Maintenance and service

7. Remove the oil filter with an oil filter wrench.
8. Before installing a new oil filter, apply a
thin coat of engine oil to the seal. 9. Clean the seal seating area. Screw on
the oil filter by hand until its seal contacts
the seating surface. Be careful not to twist
or damage the seal.
10. Tighten the oil filter further by the
amount indicated in the following table.

Blue 15208AA12A 7/8
rotation
Non-turbo models Oil filter color Part number Amount of
rotation
Black 15208AA160 1 rotation
CAUTION
. Never over tighten the oil filter
because that can result in an oil leak.
. Thoroughly wipe off any engine
oil that has spilled over the
exhaust pipe and/or under-cover.
If spilled oil is not promptly
wiped up, the oil could cause afire.
11. Reinstall under cover (turbo models). 12. Pour engine oil through the filler neck.
For the oil capacity guideline, refer to “
Engine oil ”F 12-5.
The oil quantity indicated above is onlyguideline.
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 temperature of the oil
and the time the oil is left flowing out. After
refilling the engine with oil, therefore, you
must use the level gauge 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 and drain plug.
14. Run the engine until it reaches the
normal 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 engineoil.
CAUTION
Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire.

shortened to that of the mixing coolant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Cooling fan, hose and con- nections
Your 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 following conditions occur,
the cooling fan circuit may be defective. . The engine coolant temperature gauge
exceeds the normal operating range (if
equipped). Refer to “Temperature gauge
(models with type A combination meter) ”
F 3-11.
. The coolant temperature high warning
light blinks or illuminates in RED(if
equipped). Refer to “Coolant temperature
low indicator light/Coolant temperature
high warning light ”F 3-16.
Check the fuse and replace it if necessary.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer. Refer to
“Fuses ”F 11-44 and “Fuse panel
located in the engine compartment ”F 12-
13.
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 coolant
! Checking the coolant level
1) “FULL ”level mark
2) “LOW ”level mark
Check 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 reservoir is
empty, remove the radiator cap (non-turbo
models) or the coolant filler tank cap
(turbo models) and refill as required.
NOTE (turbo models only)
The cap (without tabs) on top of the
radiator does not need to be removed.
Remove the cap (with tabs) on the
coolant filler tank on top of the engine.
3. After refilling the reservoir and the
radiator, reinstall the caps after checking
that the rubber gaskets inside the radiator
cap/coolant filler tank cap are in the properposition.

Check the deflection of the front
side belt and if there is any loosen-
ess, cracks, wear or unusual noise
on the front side belt, contact your
SUBARU dealer.
Continuing to use the vehicle with
the belt outside of the specification
may cause the engine to malfunc-
tion and the above components tomalfunction.
To check the deflection of the front side
belt, place a straightedge (ruler) across
two adjacent pulleys (alternator pulley and
crank pulley) and apply a force of 22 lbf
(98 N, 10 kgf) midway between the pulleys
by using a spring scale. The belt deflec-
tion should be the amount specified. If the
front side belt is loose, cracked or worn,

The rear side belt is a stretch-type belt,
therefore the deflection does not need to
be checked. If there are cracks or wear
confirmed on the belts and a squeaking
sound is heard from them, contact your SUBARU dealer. &
Non-turbo models
It is unnecessary to check the deflection of
the drive belt periodically because your
engine is equipped with an automatic 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 the belt is loose, cracked or worn,
contact your SUBARU dealer.

Automatic transmission fluid &Checking the fluid level
The automatic transmission fluid expands
largely as its temperature rises; the fluid
level differs according to fluid temperature.
Therefore, there are two different scales
for checking the level of hot fluid and cold
fluid on the level gauge.
Though the fluid level can be checked
without warming up the fluid on the“ COLD ”range, it is recommended to
check the fluid level when the fluid is at
operating temperature. ! Checking the fluid level when the
fluid is hot
1. Drive the vehicle several miles to raise
the temperature of the transmission fluid
up to normal operating temperature; 158
to 176 8F (70 to 80 8C) is normal.
2. Park the vehicle on a level surface and
set the parking brake.
3. First shift the select lever in each
position. Then shift it in the “P ” position,
and run the engine at idling speed.
1) Yellow handle
1) HOT range
2) COLD range
3) Full level
4) Low level
4. Pull out the level gauge and check the fluid level on the gauge. If it is below the
low level on the
“HOT ”range, add the
recommended automatic transmission
fluid up to the full level.
NOTE
Do not fill the automatic transmission
fluid over the full level. ! Checking the fluid level when the
fluid is cold
When the fluid level has to be checked
without time to warm up the automatic
transmission, check that the fluid level is
between the low level and full level on the“ COLD ”range. If it is below that range,
add fluid up to the full level. Be careful not
to overfill.
CAUTION
Be careful not to spill automatic
transmission fluid when adding it.
If automatic transmission fluid
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or a
fire. If automatic transmission fluid
gets on the exhaust pipe, be sure to
wipe it off.

&Recommended fluid
Refer to “Fluids ”F 12-9.
NOTE
Using any non-specified type of auto-
matic transmission fluid could result in
damage inside the transmission. When
replacing the automatic transmission
fluid, be sure to use the specified type. Front differential gear oil (AT models) &

Checking the fluid level
The power steering fluid expands greatly
as its temperature rises; the fluid level
differs according to fluid temperature.
Therefore, the reservoir 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.

WARNING
Never let clutch fluid contact your
eyes because clutch fluid can be
harmful to your eyes. If clutch fluid
gets in your eyes, immediately flush
them thoroughly with clean water.
For safety, wearing eye protection isadvisable.
CAUTION
. Clutch fluid absorbs moisture
from the air. Any absorbed moist-
ure can cause improper clutchoperation.
. If the vehicle requires frequent
refilling, there may be a leak. If
you suspect a problem, have the
vehicle checked at your SUBARU
dealer.
. When clutch fluid is added, be
careful not to allow any dirt into
the tank.
. Never splash the clutch fluid over
painted surfaces or rubber parts.
Alcohol contained in the clutch
fluid may damage them.
. 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
exhaust pipe, be sure to wipe itoff.
& Recommended clutch fluid
Refer to “Fluids ”F 12-9.
CAUTION
Never use different brands of clutch
fluid together. Also, avoid mixing
DOT 3 and DOT 4 brake fluids even if
they are the same brand. 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
slightly 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
approximately 1 minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake
booster operates properly if the pedal
stroke decreases with each depression. NOTE
For models equipped with the brake
assist system, when you depress the
brake pedal strongly or suddenly while
the engine is running, the following
phenomena occur. They do not indicate
any malfunctions, and the brake assist
system is operating properly.Maintenance and service
