When you do checking or servicing in the engine
compartment while the engine is running
A running engine can be dangerous. Keep your fingers, hands, clothing, hair and tools away from the cooling fan, belts and anyother moving engine parts. Removing rings, watches and ties isadvisable.
Engine hood
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.

Engine oil
Checking the oil level
Check the engine oil level at each fuel stop.
HBB061BD
HBB004BA
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.

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 theseal.
10. 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 damagethe seal.
11. Tighten it approximately two-thirds of a turn after the seal makes
contact with the lower crank case.
CAUTION
Never over tighten the oil filter because that can result in an oilleak.

12. Reinstall the cover under the oil filter.
13. Pour the specified amount of engine oil through the filler neck.Oil capacity: 2.5 liter models: 4.2 US qt (4.0 liters, 3.5 Imp qt)3.0 liter models: 6.1 US qt (5.8 liters, 5.1 Imp qt)
14. Start the engine and make sure that no oil leaks appear around the filter ’s rubber seal.
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: API classification SL or SJ with the words “ENERGY
CONSERVING II ” (if you cannot obtain the oil with SL
or SJ grade, you may use SH grade oil.) or the new API certification mark (Starburst mark) dis-
played on the container.

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 rec-
ommended 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 rec-
ommended by SUBARU.
Engine oil viscosity (thickness) affects fuel economy. Oils of lower vis-
cosity provide better fuel economy. However, in hot weather, oil of
higher viscosity is required to properly lubricate the engine.
OM-H2756
SAE viscosity numbr and applicable temperature
Recommended grade and viscosity under severe driving conditions
If the vehicle is used in desert areas, in areas with very high tempera-
tures, or used for heavy-duty applications such as a 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

Engine coolant Checking the coolant level
Check the coolant level at each fuel stop.
HBB004FB
1. Check the coolant level on the outside of the reservoir 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, re-
move the radiator cap and refill as required.

Rubber gaskets
3. After refilling the reserve tank and the radiator, reinstall the caps
and check that the rubber gaskets inside the radiator cap are in the
proper position.

4. Slowly pour the coolant and fill to the radiator filler neck and to the
reserve tank ’s “FULL” level mark. Do not pour the coolant too quickly,
as this may lead to insufficient air bleeding and trapped air in the sys-tem.
Coolant capacity: 2.5 liter models MT. 7.2 US qt (6.8 liters, 6.0 Imp qt) AT. 7.1 US qt (6.7 liters, 5.9 Imp qt)
3.0 liter models 8.4 US qt (7.9 liters, 7.0 Imp qt)

Rubber gaskets
5. Put the radiator cap back on and tighten firmly. At this time, make
sure that the rubber gasket in the radiator cap is correctly in place.
6. Start and run the engine for more than five minutes at 2,000 to
3,000 rpm.

have the spark plugs replaced by your SUBARU dealer.
The spark plugs should be replaced according to the maintenance
schedule in the “Warranty and Maintenance Booklet ”.
