&Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in
areas with very high temperatures, or is
used for heavy-duty applications, use of
oil with the following grade and viscosities
is recommended.
API classification SM (or SL): SAE viscosity No.: 30, 40, 10W-50,
20W-40, 20W-50
& Synthetic oil
You can use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using
synthetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner ’s Manual, and must follow
the oil and filter changing intervals shown
in the maintenance schedule. Cooling system
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap isremoved.
CAUTION
. Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). This coolant
should not be mixed with any
other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. Should it be
necessary to top up the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand or
type, the maintenance interval is shortened to that of the mixingcoolant.
. 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 coolant temperature high
warning light blinks or illuminates in RED,
the cooling fan circuit may be defective.
Refer to “Coolant temperature low indica-
tor light/Coolant temperature high warninglight ”F 3-13.
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-
8.
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 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.
CAUTION
. Be careful not to spill engine
coolant 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.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface. !
Changing the coolant
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap isremoved.
Always add genuine SUBARU cooling
system conditioner whenever the coolant
is replaced.
Change the engine coolant and add
genuine SUBARU cooling system condi-
tioner using the following procedures
according to the maintenance schedule.
1. Remove the under cover. Maintenance and service

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.
NOTE (turbo models only)
The cap (without tabs) on top of the
radiator does not need to be removed.
To add coolant, remove the cap (with
tabs) on the coolant tank on top of theengine.
4. Install the under cover.Non-turbo models
1) Fill up to this level
Turbo models
1) Fill up to this level
5. Slowly pour the coolant and fill up to
just below the filler neck, allowing enough room to add genuine SUBARU cooling
system conditioner in the radiator. Add
genuine SUBARU cooling system condi-
tioner until the coolant level reaches the
filler neck. Do not pour the coolant too
quickly, as this may lead to insufficient air
bleeding and trapped air in the system.
Guideline of coolant quantity (including
coolant in reservoir tank): Non-turbo models:MT: 7.2 US qt (6.8 liters, 6.0 Imp qt)
AT: 7.1 US qt (6.7 liters, 5.9 Imp qt)
Turbo models: 8.5 US qt (8.0 liters, 7.0 Imp qt)

1)“FULL ”level mark
2) “LOW ”level mark
CAUTION
. Be careful not to spill engine
coolant 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.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
6. Pour the coolant and fill to the reser-
voir tank ’s “FULL ”level mark.
7. Put the radiator cap back on and
tighten firmly. At this time, make sure that
the rubber gasket in the radiator cap is
correctly in place.
8. Start and race the engine at 2,000 to
3,000 rpm for 5 to 6 times within 40seconds.
9. Stop the engine and wait until the
coolant cools down (122 to 140 8F [50 to
60 8C]). If there is any loss of coolant, add
coolant to the radiator ’s filler neck and to
the reserve tank ’s “FULL ”level.
10. Put the radiator cap and reservoir cap
back on and tighten firmly. Air cleaner element
WARNING
Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters
intake air but also stops flames if
the engine backfires. If the air
cleaner element is not installed
when the engine backfires, you
could be burned.
CAUTION
When replacing the air cleaner ele-
ment, use a genuine SUBARU air
cleaner element. If it is not used,
there is the possibility of causing a
negative effect to the engine.
The air cleaner element functions as a
filter screen. When the element is perfo-
rated or removed, engine wear will be
excessive and engine life shortened.
It is not necessary to clean or wash the element. Maintenance and service

Windshield washer fluid
If you spray washer fluid on the windshield
but the supply of washer fluid appears to
diminish, check the level of washer fluid in
the tank.
Washer fluid level gauge
Remove the washer tank filler cap, then
check the fluid level indicated by the level
gauge (attached to the inside of the cap).
If the level is near the “Low ”mark, add
fluid until it reaches the “Hi ”level on the level gauge or the
“FULL ”mark on the
tank.
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean
water.
In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid. SUBARU Windshield Washer Fluid
contains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the followingtable.

CAUTION
Never use engine coolant as washer
fluid because it could cause paintdamage.
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
