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

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.

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

Cooling systemWARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
CAUTION
The cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-around coolant which providesprotection 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 improp-er coolants may result in corrosion in the cooling system. It is im-portant to maintain protection against freezing and corrosion,even if freezing temperatures are not expected. Never mix differ-ent kinds of coolant. Do not splash the engine coolant over painted parts. The alco-
hol contained in the engine coolant may damage the paint sur-face.
Hose and connections
Your vehicle employs an electric cooling fan which is thermostatically
controlled to operate when the engine coolant reaches a specific tem-
perature.If the radiator cooling fan 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 the
engine cooling system. It is recommended that the cooling systemand connections be checked for leaks, damage, or looseness.

Changing the coolant
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
Change the engine coolant using the following procedures according
to the maintenance schedule in the “Warranty and Maintenance Book-
let”. 1. Remove the under cover.
2. Place a proper container under the drain plug and loosen the drainplug.

3. Loosen the radiator cap to drain the coolant from the radiator. Then
drain the coolant from the reserve tank. Tighten the drain plug secure-
ly.

Rear differential gear oil
Checking the gear oil level CAUTION
If the vehicle requires frequent refilling, there may be an oil leak. If you suspect a problem, have the vehicle checked at your
SUBARU dealer.
Your vehicle may be equipped with a rear differential protector. The
differential protector provides protection to the rear differential assem-
bly during off-road use. Removal of the rear differential protector is not
required when checking the oil level.
