In choosing an oil, you want the proper
quality and viscosity, as well as one that
will add to fuel economy. The following
table 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.SAE viscosity number and applicable
temperature
*: 5W-30 is preferred.Engine oil viscosity (thickness) affects fuel
economy. Oils of lower viscosity provide
better fuel economy. However, in hot
weather, oil of higher viscosity is required
to properly lubricate the engine.
& Recommended grade and
viscosity under severe driv-
ing conditionsIf the vehicle is used in desert areas, in
areas with very high temperatures, or
used for heavy-duty applications such as
towing a trailer, 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
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 is
removed.
CAUTION
. The cooling system has been
filled at the factory with a high
quality, corrosion-inhibiting,
year-around coolant which pro-
vides protection against freezing
down to 33 8F( 36 8C). For add-
ing, use genuine SUBARU cool-
ant or an equivalent: a mixture of
50% soft water (or clear and
drinkable water) and 50% phos-
phate or non-amine type coolant.
Use of improper coolants may
result in corrosion in the cooling
system. It is important to main-
tain protection against freezing
and corrosion, even if freezing

Maintenance and service
temperatures are not expected.
Never mix different kinds of cool-
ant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Hose and connectionsYour 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
defective. 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 coolant! Checking the coolant levelCheck 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.

over painted parts. The alcohol

may damage the paint surface.
! Changing the coolant
Always add genuine Subaru cooling sys-
tem 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
in the “Warranty and Maintenance Book-
let ”. 1. Remove the under cover.
2.5-liter models
1) Drain plug3.0-liter models
1) Drain plug
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.
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 is
removed.
4. Install the under cover.

Non-turbo models
1) Fill up to hereTurbo models
1) Fill up to here5. 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.
Coolant capacity (Guideline):
2.5-liter non-turbo models:MT. 6.8 US qt (6.4 liters, 5.6 Imp qt)
AT. 6.7 US qt (6.3 liters, 5.5 Imp qt)
2.5-liter turbo models: MT. 7.7 US qt (7.3 liters, 6.4 Imp qt)
AT. 7.6 US qt (7.2 liters, 6.3 Imp qt)
3.0-liter models: 7.6 US qt (7.2 liters, 6.3 Imp qt)
CAUTION
. Be careful not to spill engine

touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on

the rubber gasket in the radiator cap is
correctly in place.
8. Start and run the engine for more than
five minutes at 2,000 to 3,000 rpm.
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.
The air cleaner element is a dry type. It is
unnecessary to clean or wash the ele-
ment.
& Replacing the air cleaner
elementReplace the air cleaner element according
to the maintenance schedule in the
“Warranty and Maintenance Booklet ”. Un-
der extremely dusty conditions, replace it
more frequently. It is recommended that
you always use genuine SUBARU parts.
! Non-turbo models1) Connector
2) Duct
3) Clamp1. 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
cleaner case.

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 modelsIt is unnecessary to check belt tension
periodically because your engine is
equipped with an automatic belt tension
adjuster. However, replacement of the belt
should be done according to the main-
tenance schedule in the "Warranty and
Maintenance Booklet". Consult your
SUBARU dealer for replacement.
If a belt is loose, cracked, or worn, contact
your SUBARU dealer.

Automatic transmission fluid& Checking the fluid levelThe 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 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.
! 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; 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 selector lever in each
position. Then shift it in the “P ” position,
and run the engine at idling speed.

fluid, be sure to use the kind specified.
For 4-speed automatic transmission:
For optimum transmission perfor-
mance, only use the automatic trans-
mission fluid that is recommended and
provided by Subaru.
If the recommended automatic trans-
mission fluid is unavailable, Dexron III
may be temporarily used. If the Dexron
III is used continuously there will be a
noticeable increase in the vibration and
noise from the automatic transmission.

cause a bad smell, smoke, and/or a
fire. If oil gets on the exhaust pipe,
be sure to wipe it off.
