WARNING
Never turn the ignition switch to the “LOCK”
position while the vehicle is being towed be-
cause the steering wheel and the direction ofthe wheels will be locked. Remember that the brake booster and pow-
er steering do not function when the engine is not running. Because the engine is turned off,
it will take greater effort to operate the brakepedal and steering wheel.
CAUTION
If transmission failure occurs, transport
your vehicle on a flat-bed truck. Do not run the engine while being towed in
this method. Transmission damage could re- sult if the vehicle is towed with the engine running. For vehicles with automatic transmission,
the traveling speed must be limited to lessthan 20 mph (30 km/h) and the traveling dis-tance to less than 31 miles (50 km). For greater speeds and distances, transport your
vehicle on a flat-bed truck. Maintenance toolsYour vehicle is equipped with the following mainte-
nance tools:
Wheel cover remover (vehicles with wheel covers)
Screwdriver
Towing hook (eye bolt)
Wheel nut wrench

Maintenance schedule
The scheduled maintenance items required to be
serviced at regular intervals are shown in the “War-
ranty and Maintenance Booklet ”.
For details of your maintenance schedule, read theseparate “Warranty and Maintenance Booklet ”.Maintenance precautions
When maintenance and service are required, it is
recommended that all work be done by an autho-
rized SUBARU dealer.
If you perform maintenance and service by yourself,
you should familiarize yourself with the information
provided in this section on general maintenance andservice for your SUBARU.
Incorrect or incomplete service could cause
improper or unsafe vehicle operation. Any problems
caused by improper maintenance and service per-
formed by you are not eligible for warranty cover-age.
WARNING

Testing of an All-Wheel Drive vehicle must
NEVER be performed on a single two-wheel
dynamometer or similar apparatus. Attempt-ing to do so will result in transmission dam-age and in uncontrolled vehicle movement and may cause an accident or injuries to per-
sons nearby. Always select a safe area when performing
maintenance on your vehicle.

WRX:
1. Lift the hood slightly and remove the hood prop
from the slot in the hood and return the prop to its
retainer.
2. Lower the hood until it approaches about 12 in.
(30 cm) from the closed position and let it drop.
After closing the hood, be sure the hood is securelylocked.
If this does not close the hood, release it from a
slightly higher position. Do not push the hood forci-
bly to close it. It could deform the metal.
WARNING
Always check that the hood is properly locked before you start driving. If it is not, it might fly open while the vehicle is moving and block
your view, which may cause an accident and
serious bodily injury.

If you check the oil level just after stopping the en-
gine, 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
engine oil level reading may be in a range betweenthe upper level and the notch mark. This is caused
by thermal expansion of the engine oil.
To prevent overfilling the engine oil, do not add any
additional oil above the upper level when the engineis 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
frequently 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
about 10 minutes to ease draining the engine oil.
2. Park the vehicle on a level surface and stop theengine.
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.
WARNING
Be careful not to burn yourself with hot en- gine oil.
5. Wipe the seating surface of the drain plug with a
clean cloth and tighten it securely with a new seal-

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 ap-
plications such as towing a trailer, use of oil with the
following 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 classification, viscosity and grade shown inthis 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 radiator cap until the engine has been shut off and has cooled
down completely. Since the coolant is underpressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap isremoved.
CAUTION

The cooling system has been filled at the
factory with a high quality, corrosion-inhibit-
ing, 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 cool-
ant. Use of improper coolants may result in
corrosion in the cooling system. It is impor- tant to maintain protection against freezing and corrosion, even if freezing temperaturesare not expected. Never mix different kinds ofcoolant.

5. Slowly pour the coolant and fill to the radiator fill-
er neck. Do not pour the coolant too quickly, as this
may lead to insufficient air bleeding and trapped airin the system.

this time, make sure that the rubber gasket in the ra-
diator cap is correctly in place.
8. Start and run the engine for more than five min-utes at 2,000 to 3,000 rpm.
9. Stop the engine and wait until the coolant coolsdown (122 to 140°F [50 to 60 °C]). 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
The air cleaner element functions as a filter screen.
When the element is perforated or removed, engine
wear will be excessive and engine life shortened.
The air cleaner element is a viscous type. It is un-
necessary to clean or wash the element.
WARNING
Do not operate the engine with the air cleaner
element removed. The air cleaner element notonly filters intake air but also stops flames ifthe engine backfires. If the air cleaner elementis not installed when the engine backfires, youcould be burned.
Replacing the air cleaner element
Non-turbo models
Replace the air cleaner element according to the
maintenance schedule in the “Warranty and Mainte-
nance Booklet ”. Under extremely dusty conditions,
replace it more frequently. It is recommended that
you always use genuine SUBARU parts.

1) Specified range
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 recommended fluid as necessary to bring the level between the “MIN” and “MAX” line.
If the fluid level is extreme low, it may indicate pos-
sible leakage. Consult your SUBARU dealer for in- spection.
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 al- low any dirt into the tank. And never use dif-
ferent brands together. Avoid spilling fluid when adding it in the
tank.
