Maintenance and service
the materials in the vehicle may be hazardous if
improperly used or handled, for example, bat-
tery acid.
Your vehicle should only be serviced by per-
sons fully competent to do so. Serious person-
al injury may result to persons not experienced
in servicing vehicles. Always use the proper tools and make certain
that they are well maintained. Never get under the vehicle supported only
by a jack. Always use a safety stands to sup-
port the vehicle. Never keep the engine running in a poorly
ventilated area, such as a garage or other
closed areas. Do not smoke or allow open flames around
the fuel or battery. This will cause a fire. Because the fuel system is under pressure,
replacement of the fuel filter should be per-
formed only by your SUBARU dealer. Wear adequate eye protection to guard
against getting oil or fluids in your eyes. If
something does get in your eyes, thoroughly
wash them out with clean water. Do not tamper with the wiring of the SRS air-
bag system or seatbelt pretensioner system, or
attempt to take its connectors apart, as that may activate the system or it can render it inop-
erative. The wiring and connectors of these
systems are yellow for easy identification. NEV-
ER use a circuit tester for these wiring.
If your SRS airbag or seatbelt pretensioner
needs service, consult your nearest SUBARU
dealer.
Before checking or servicing in the en-
gine compartment
Always stop the engine and set the parking
brake firmly to prevent the vehicle from mov-
ing. Always let the engine cool down. Engine
parts become very hot when the engine is run-
ning and remain hot for some time after the en-
gine is stopped. Do not spill engine oil, engine coolant, brake
fluid or any other fluid on hot engine compo-
nents. This may cause a fire. Always remove the key from the ignition
switch. When the ignition switch is in the “ON”
position, the cooling fan may operate suddenly

Maintenance and service
a bad smell, smoke, and/or a fire.
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.
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.
To prevent overfilling the engine oil, do not add any
additional oil above the upper level when the engine is
cold. Changing the oil and oil filter
Change 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, when towing a trailer, or when driving in ex-
tremely cold whether.
1. Warm up the engine by letting the engine idle for
about 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.
4. Open the access cover by removing the six clips
and turning the access cover counterclockwise. The
drain plug and oil filter will be exposed.

–CONTINUED –
1) Drain plug
5. 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
oil.
6. 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.
1) Oil filter
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 rubber seal seating area of the lower
crank case and install the oil filter by hand turning. Be
careful not to twist or damage the seal.
10.Tighten it approximately two-thirds of a turn after
the seal makes contact with the lower crank case.
Never over tighten the oil filter because that can

result in an oil leak.
11.Close the access cover by turning it clockwise and
reinstall the six clips in their original positions.
12.Pour engine oil through the filler neck.
Oil quantity (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 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 pouring oil
into the engine, therefore, you must use the dipstick to
confirm that the level is correct.
13.Start the engine and make sure that no oil leaks ap-
pear around the filter’s rubber seal.
14.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
Oil grade:
API classification SL or SJ with the words “ENER-
GY CONSERVING” (if you cannot obtain the oil
with the SL or SJ grade, you may use SH or SG
grade oil.) or the new API certification mark (Star-
burst mark) displayed on the 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

Maintenance and service

Recommended grade and viscosity
under severe driving conditions
If the vehicle is used in desert areas, in areas with very
high temperatures, or used for heavy-duty applica-
tions such as towing a trailer, use of oil with the follow-
ing grade and viscosities is recommended.
API classification SL or SJ: 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 clas-
sification, viscosity and grade shown in this owner’s
manual, and must follow the oil and filter changing in-
tervals shown in the maintenance schedule.
Cooling 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.
The cooling system has been filled at the facto-
ry with a high quality, corrosion-inhibiting,
year-around coolant which provides protection
againstfreezingdownto–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.
