Maintenance schedule
The scheduled maintenance items required to be serviced at regular intervals are shown in the Warranty and Maintenance Booklet .
For details of your maintenance schedule, read the separate Warranty and Maintenance Booklet .
Maintenance precautions
When maintenance and service are required, it is recommended that all work be done by an authorized SUBARU dealer.
If you perform maintenance and service by yourself, you should familiarize yourself with the information provided in this section on general maintenance and service for your SUBARU.
Incorrect or incomplete service could cause improper or unsafe vehicle operation. Any problems caused by improper maintenance and service performed by you are not eligible for warranty coverage.
Testing of an All-Wheel Drive vehicle must NEVER be performed on a single two-wheel dynamometer or similar apparatus. Attempting to do so will result in transmission damage and in uncontrolled vehicle movement and may cause an accident or injuries to persons nearby.
Always select a safe area when performing maintenance on your vehicle.
Maintenance and service 11-3
Always be very careful to avoid injury when working on the vehicle. Remember that some of the materials in the vehicle may be hazardous if improperly used or handled, for example, battery acid.
Your vehicle should only be serviced by persons fully competent to do so. Serious personal 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 support 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 performed only by your SUBARU dealer.
CONTINUED
11-4 Maintenance and service
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 airbag system or seatbelt pretensioner system, or attempt to take its connectors apart, as that may activate the system or it can render it inoperative. The wiring and connectors of these systems are yellow for easy identification. NEVER 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 engine compartment
Always stop the engine and set the parking brake firmly to prevent the vehicle from moving.
Always let the engine cool down. Engine parts become very hot when the engine is running and remain hot for some time after the engine is stopped.
Do not spill engine oil, engine coolant, brake fluid or any other fluid on hot engine components. 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 even when the engine is stopped.
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 any other moving engine parts. Removing rings, watches and ties is advisable.
Engine hood
To open the hood:
B00002
1. If the wiper blades are lifted off the windshield, return them to their original positions.
2. Pull the hood release knob under the instrument panel.
B00447
3. Release the secondary hood release located under the front grille by moving the lever toward the left.
B00448
Lift up the hood, release the hood prop from its retainer and put the end of the
Maintenance and service 11-5
hood prop into the slot in the hood. To close the hood:
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 approximately 12 in (30 cm) from the closed position and let it drop.
After closing the hood, be sure the hood is securely locked.
If this does not close the hood, release it from a slightly higher position. Do not push the hood forcibly to close it. It could deform the metal.
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.
1. Park the vehicle on a level surface and stop the engine.
|
|
B00467 |
2. |
Pull out the dipstick, wipe it clean, and |
|
insert it again. |

B00418
1)Notch
2)Upper level
3)Lower level
4.Pull out the dipstick again and check the oil level on it. If it is below the lower level, add oil to bring the level up to the upper level.
Use only engine oil with the recommended grade and viscosity. Be careful not to spill engine oil when adding it. If oil touches the exhaust pipe, it may cause a bad smell, smoke, and/or a fire. If engine oil gets on the exhaust pipe, be sure to wipe it off.
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 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.
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 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 approximately 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.
B00449
Turbo models
B00450
Non-turbo models
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.
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 completely drained out.
6. Remove under cover.

Engine oil viscosity (thickness) affects fuel economy. Oils of lower viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the engine.
Use only engine oil with the recommended grade and viscosity.
Recommended grade and viscosity under severe driving conditions
If the vehicle is used in desert areas, in ar-

eas with very high temperatures, or used for heavy-duty applications such as towing a trailer, use of oil with the following grade and viscosities is recommended.
API classification SM (or SL):
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 in this owner s manual, and must follow the oil and filter changing intervals shown in the maintenance schedule.
11-12 Maintenance and service
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 removed.
The cooling system has been filled at the factory with a high quality, corrosion-inhibiting, yeararound 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 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 different kinds of coolant.
Do not splash the engine coolant over painted parts. The alcohol contained in the engine coolant may damage the paint surface.
Cooling fan, hose and connections
Your vehicle employs an electric cooling fan which is thermostatically controlled to operate when the engine coolant reaches a specific temperature.
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 system and connections be checked for leaks, damage, or looseness.

Check the coolant level at each fuel stop. 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 theLOW level mark, add coolant up to theFULL level mark. If the reserve tank is empty, remove the radiator cap and refill as required.
B00018
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.
Be careful not to spill engine coolant when adding it. If coolant touches the exhaust pipe, it may cause a bad smell, smoke, and/or a fire. If engine coolant gets on the exhaust pipe, be sure to wipe it off.
Do not splash the engine coolant over painted parts. The alcohol contained in the engine coolant may damage the paint surface.
Changing the coolant
B00019
Always add genuine Subaru cooling system conditioner whenever the coolant is replaced.
Change the engine coolant and add genuine Subaru cooling system conditioner using the following procedures according to the maintenance schedule.
1. Remove the under cover.
2. Place a proper container under the drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the coolant from the radiator. Then drain the coolant from the reserve tank. Tighten the drain plug securely.
NOTE (Turbo model only)
The cap (without tabs) on top of the radiator does not need to be removed. To

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 unnecessary to clean or wash the element.
Do not operate the engine with the air cleaner element removed. The air cleaner element not only filters intake air but also stops flames if the engine backfires. If the air cleaner element is not installed when the engine backfires, you could be burned.
Replacing the air cleaner element
Replace the air cleaner element according to the maintenance schedule in the Warranty and Maintenance Booklet . Under extremely dusty conditions, replace it more frequently. It is recommended that you always use genuine SUBARU parts.
