To prevent serious damage to the emission control system, you should do the following:
Reduce vehicle speed.
Avoid hard acceleration.
Avoid steep uphill grades.
Reduce the amount of cargo, if possible.
Stop towing a trailer as soon as possible.
The CHECK ENGINE warning light may stop blinking and come on
steadily after several driving trips. You should have your vehicle
checked by an authorized SUBARU dealer immediately.
Charge warning light
If this light comes on when the engine is running, it may indicate that the
charging system is not working properly. If the light comes on while driving or does not go out after the engine
starts, stop the engine at the first safe opportunity and check the alterna-
tor belt. If the belt is loose, broken or if the belt is in good condition but
the light remains on, contact your nearest SUBARU dealer immediately. Oil pressure warning light
CAUTION
Do not operate the engine with the oil pressure warning light on. This may cause serious engine damage.
If this light comes on when the engine is running, it may indicate that the
engine oil pressure is low and the lubricating system is not working prop-
erly.If the light comes on while driving or does not go out after the engine
starts, stop the engine at the first safe opportunity and check the engine
oil level. If the oil level is low, add oil immediately. If the engine oil is at
the proper level but the light remains on, contact your nearest SUBARU
dealer immediately.

than three. Under this condition, the vehicle operator should be
instructed to drive his/her vehicle for a few days to set the monitors and
return for an emission re-inspection.
Owners of rejected or failing vehicles should contact their Subaru
Dealer for service.
Preparing to drive
You should perform the following checks and adjustments every day be-
fore you start driving.
1. Check that all windows, mirrors, and lights are clean and unob- structed.
2. Check the appearance and condition of the tires. Also check tires for
proper inflation.
3. Look under the vehicle for any sign of leaks.
4. Check that the hood, trunk and rear gate are fully closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside and outside mirrors.
7. Fasten your seatbelt. Check that your passengers have fastened theirseatbelts.
8. Check the operation of the warning and indicator lights when the igni-
tion switch is turned to the “ON” position.
9. Check the gauges, indicator and warning lights after starting the en-gine. NOTE Engine oil, engine coolant, brake fluid, washer fluid and other fluid
levels should be checked daily, weekly or at fuel stops.

Do not use oil or grease on the wheel studs or nuts when the
spare tire is installed. This could cause the nuts to become loose and lead to an accident. Never place a tire or tire changing tools in the passenger
compartment after changing wheels. In a sudden stop or colli-
sions, loose equipment could strike occupants and cause injury.Store the tire and all tools in the proper place.
If you have a flat tire while driving, never brake suddenly; keep driving
straight ahead while gradually reducing speed. Then slowly pull off the
road to a safe place.
1. Park on a hard, level surface, whenever possible, then stop the en- gine.
2. Set the parking brake securely and shift a manual transmission ve-
hicle in reverse or an automatic transmission vehicle in the “P” (Park)
position.
3. Turn on the hazard warning flasher and have everyone get out of thevehicle.
4. Put wheel blocks at the front and rear of the tire diagonally opposite
the flat tire.

Engine overheating
WARNING
Never attempt to remove the radiator cap until the engine has been shut off and has fully cooled down. When the engine is hot,the coolant is under pressure. Removing the cap while the engineis still hot could release a spray of boiling hot coolant, which
could burn you very seriously.
If the engine overheats, safely pull off the road and stop the vehicle in asafe place. If steam is coming from the engine compartment
Turn the engine off and get everyone away from the vehicle until itcools down. If no steam is coming from the engine compartment
1. Keep the engine running at idling speed.
2. Open the hood to ventilate the engine compartment.
Confirm that the cooling fan is turning. If the fan is not turning, im-
mediately turn the engine off and contact your authorized dealer for
repair.
3. After the engine coolant temperature has dropped, turn off the en-gine.
If the temperature gauge stays at the overheated zone, turn the en-
gine off.
4. After the engine has fully cooled down, check the coolant level in
the reserve tank.If the coolant level is below the “MIN” mark, add coolant up to the
“MAX” mark.
5. If there is no coolant in the reserve tank, add coolant to the reserve
tank. Then remove the radiator cap and fill the radiator with coolant.
If you remove the radiator cap from a hot radiator, first wrap a thick
cloth around the radiator cap, then turn the cap counterclockwise
slowly without pressing down until it stops. Release the pressure from

CAUTION
If transmission failure occurs, transport your vehicle on a flat-
bed truck. Do not run the engine while being towed in this method. Trans-
mission damage could result if the vehicle is towed with theengine running. For vehicles with automatic transmission, the traveling speed
must be limited to less than 20 mph (30 km/h) and the traveling
distance to less than 31 miles (50 km). For greater speeds and
distances, transport your vehicle on a flat-bed truck.

1. Check the transmission and differential oil levels and add oil to
bring it to the upper level if necessary.
2. Release the parking brake and put the transmission in neutral.
3. The ignition switch should be in the “ACC” position while the ve-
hicle is being towed.
4. Take up slack in the towline slowly to prevent damage to the ve-hicle.

Engine oil
Checking the oil level
Check the engine oil level at each fuel stop.
HBB061BD
HBB004JA
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 inserted until it stops with the
graphic symbol
on its top appearing as shown in the illustra-
tion.
4. Pull out the dipstick again and check the oil level on it. If it is belowthe lower level, add oil to bring the level up to the upper level.
CAUTION
Use only engine oil with the recommended grade and viscosity.
If you check the oil level just after stopping the engine, wait a few min-
utes 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 oilabove the upper level when the engine is cold.
In 2.5-liter-engine models, the dipstick has a notch above the upper level.
Just after driving or while the engine is warm, the engine oil level
reading may be in a range between the upper level and the notch
mark. This is caused by thermal expansion of the engine oil.

Changing the oil and oil filter
Change the oil and oil filter according to the maintenance 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 the engine.
3. Remove the oil filler cap.
HBB005BB
4. Drain out the engine oil by removing the drain plug while the en-
gine 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 engine oil.
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 com-pletely drained out.

11-1212. Reinstall the cover under the oil filter.
13. Pour engine oil through the filler neck.
Oil capacity (Guideline): 2.5 liter models: 4.2 US qt (4.0 liters, 3.5 Imp qt)3.0 liter models: 5.9 US qt (5.6 liters, 4.9 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.
14. Start the engine and make sure that no oil leaks appear around the filter ’s rubber seal and drain plug.
15. 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 recommended grade and viscosity.
Oil grade: ILSAC GF-3, which can be identified with the new API certification mark (Starburst mark)
or API classification SL with the words “ENERGY CON-
SERVING” (if you cannot obtain the oil with SL grade,
you may use SJ grade “ENERGY CONSERVING ” oil).
These recommended oil grades can be identified by looking for either
or both of the following marks displayed on the oil container.
