Maintenance and service
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.
WARNING
D 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 . D Always select a safe area when performing maintenance on your vehicle. D 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. D 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.

D Always use the proper tools and make certain that they are well maintained. D Never get under the vehicle supported only by a jack. Always use a safety stands to support the vehicle. D Never keep the engine running in a poorly ventilated area, such as a garage or other closed areas. D Do not smoke or allow open flames around the fuel or battery. This will cause a fire. D Because the fuel system is under pressure, replacement of the fuel filter should be performed only by your SUBARU dealer. D Wear adequate eye protection to guard against getting oil or fluids in your eyes. If something does get in your eyes, thorough­ly wash it out with clean water. D 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.
J Before checking or servicing in the engine compart -
ment
D Always stop the engine and set the parking brake firmly to pre­vent the vehicle from moving. D 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. D Do not spill engine oil, engine coolant, brake fluid or any other fluid on hot engine components. This may cause a fire. D Always remove the key from the ignition switch. When the ignition switch is in the “ON” position, the cooling fan may oper- ate suddenly even when the engine is stopped.

on its top appearing as shown in the illustra-
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 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.

Maintenance and service
B 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 en­gine is still warm. The used oil should be drained into an appropriate container and disposed of properly.
WARNING

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 rec­ommended 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 rec­ommended by SUBARU.
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.

Maintenance and service
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 under pressure, you may suffer serious burns from a spray of boiling hot coolant when the cap is removed.
CAUTION
D The cooling system has been filled at the factory with a high quality, corrosion-inhibiting, 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 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. D Do not splash the engine coolant over painted parts. The alco­hol contained in the engine coolant may damage the paint sur­face.
B 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.

radiator’s filler neck and to the reserve tank’s FULL level.
8. Put the radiator cap and reservoir cap back on and tighten firmly.
Air cleaner element
WARNING
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.
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.
B 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.
