Engine oil& Checking the oil levelCheck the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine.2. Pull out the dipstick, wipe it clean, and
insert it again.
3. Be sure the dipstick is correctly in-
serted until it stops with the graphic
symbol “
”on its top appearing as
shown in the illustration.
2.5-liter models
1) Notch
2) Upper level
3) Lower level
3.0-liter models
1) Upper level
2) Lower level4. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the
upper level.
CAUTION
. Use only engine oil with the
recommended grade and vis-
cosity.

Oil capacity (Guideline):
2.5-liter models: 4.2 US qt (4.0 liters, 3.5
Imp qt)
3.0-liter models: 5.8 US qt (5.5 liters, 4.8
Imp qt)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 refilling the engine with
oil, 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 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 engine
oil.
& Recommended grade and
viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.Oil 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.
ILSAC Certification Mark (Starburst Mark)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 capabilities

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

the oil level on it. If it is below the lower
level, add oil through the dipstick hole to
bring the level up to the upper level.
CAUTION
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.

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.

4) Lower level4. Pull out the dipstick and check the fluid
level on the gauge. If it is below the lower
level on the “HOT”range, add the recom-
mended automatic transmission fluid up to
the upper 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 to see that the fluid
level is between the lower level and upper
level on the “COLD”range. If it is below
that range, add fluid up to the upper 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.&

matic transmission fluid.

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.

Power steering fluid& Checking the fluid level
WARNING
Be careful not to burn yourself
because the fluid may be hot.
CAUTION
. When power steering fluid is
being added, use only clean fluid,
and be careful not to allow any
dirt into the tank. And never use
different brands together.
. Avoid spilling fluid when adding
it in the tank. .
Be careful not to spill power
steering fluid when adding it. If
power steering fluid touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
power steering fluid gets on the
exhaust pipe, be sure to wipe it
off.
The power steering fluid expands greatly
as its temperature rises; the fluid level
differs according to fluid temperature.
Therefore, 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.
2. 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
between “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
surface of the reservoir tank.
3. If the fluid level is lower than the
applicable “MIN ”line, add the recom- mended fluid as necessary to bring the
level between the
“MIN”and “MAX ”line.
If the fluid level is extreme low, it may
indicate possible leakage. Consult your
SUBARU dealer for inspection.
& Recommended fluidUse one of the following types of auto-
matic transmission fluid.

sion Fluid

sion Fluid Type-HP
