a bad smell, smoke, and/or a fire. If engine oil
gets on the exhaust pipe, be sure to wipe it off.
If you check the oil level just after stopping the engine,
wait a few minutes for the oil to drain back into the oil
pan before checking the level.
To prevent overfilling the engine oil, do not add any
additional oil above the upper level when the engine is cold.
The dipstick has a notch above the upper level.
Just after driving or while the engine is warm, the en-
gine oil level reading may be in a range between the
upper level and the notch mark. This is caused by ther-
mal expansion of the engine oil. „ Changing the oil and oil filter
„
Changing
„ Oil and oil filterChange the oil and oil filter according to the mainte-
nance schedule in the “Warranty and Maintenance
Booklet”.
The engine oil and oil filter must be changed more fre-
quently than listed in the maintenance schedule when
driving on dusty roads, when short trips are frequently
made, or when driving in extremely cold whether.
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 en-
gine.
3. Remove the oil filler cap.
1) Drain plug
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.
Be careful not to burn yourself with hot engine

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 three clips at the front of the cover under
the oil filter.

7. Slide the cover toward the vehicle front to remove it.
8. Remove the oil filter with an oil filter wrench.
9. Before installing a new oil
filter, apply a thin coat of
engine oil to the seal.
10.Clean the rubber seal seat ing area of the bottom of
engine and install the oil filter by hand turning. Be
careful not to twist or damage the seal.
11.Tighten the oil filter by the amount indicated in the
following table after the seal makes contact with the
bottom of engine.
y Never over tighten the oil filter because that
can result in an oil leak. y Thoroughly wipe off any engine oil that has
spilled over the exhaust pipe and/or under-cov-
er. If left unremoved, th e oil could catch fire.
12.Reinstall the cover under the oil filter.
13.Pour engine oil through the filler neck.

Oil capacity (Guideline):
4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only a guideline.
The necessary quantity of o il 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 dipstick to
confirm that the level is correct.
14.Start the engine and make sure that no oil leaks ap-
pear around the filter’s rubber seal and drain plug.
15.Run the engine until it reaches the normal operat-
ing 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
„Recommended
„ Oil grade and viscosity
Use only engine oil with the recommended
grade and viscosity.
Oil grade:
ILSAC GF-4, which can be identified with the IL-
SAC 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 dis-
played on the oil container.

API Service label
1) Indicates the oil quality by API designations
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 vis-
cosity, 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 togeth-
er as long as they are the same API classification and
SAE viscosity as those recommended by SUBARU. SAE viscosity No. and applicable temperature
*: 5W-30 is preferred.
Engine oil viscosity (thickness) affects fuel economy.
Oils of lower viscosity pr ovide better fuel economy.
However, in hot weather, oil of higher viscosity is re-
quired to properly lubricate the engine. „ Recommended grade and viscosity

high temperatures, or used for heavy-duty applica-
tions such as towing a trailer, use of oil with the follow-

Cooling systemCooling system
Never attempt to remove the radiator 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 boiling hot coolant when the cap is re-
moved.
yThe cooling system has been filled at the fac-
tory with a high quality, corrosion-inhibiting,
year-around coolant which provides protection
against freezing down to –33 °F (–36 °C). For
adding, use genuine SUBARU coolant or an
equivalent: a mixture of 50% soft water and 50%
ethylene-glycol basis coolant. Use of improper
coolants may result in corrosion in the cooling
system. It is important to maintain protection
against freezing and corrosion, even if freezing
temperatures are not expected. Never mix dif-
ferent kinds of coolant. y Do not splash the engine coolant over paint-

ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
„ Hose and connections
„Hose and connectionsYour vehicle employs an electric cooling fan which is
thermostatically controlled to operate when the engine
coolant reaches a s pecific temperature.
If the radiator cooling f an does not operate even when
the engine coolant temperature 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 necessary, there may
be a leak in th e engine cooling syst em. It is recom-
mended that the cooling system and connections be
checked for leaks, damage, or looseness. „

TChecking 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 reser-
voir 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 re-
fill as required.

3. After refilling the reserve tank and the radiator, re-
install the caps and check that the rubber gaskets in-
side the radiator cap are in the proper position.
y 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.y Do not splash the engine coolant over paint-
ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
T Changing the coolant
Always add genuine SUBARU cooling system condi-
tioner whenever the coolant is replaced.
Change the engine coolant and add genuine SUBARU cooling system cond itioner using the following proce-
dures according to the maintenance schedule in the
“Warranty and Maintenance Booklet”.
1. Remove the under cover.
