ished to the point where the luster or tone cannot be restored, lightly polish the surface with a fine-grained compound. Never polish just the affected area, but include the surrounding area as well. Always polish in only one direction. A No. 2000 grain compound is recom- mended. Never use a coarse-grained compound. Coarse-grained compounds have a smaller grain-size number and could damage the paint. After polishing with a compound, coat with wax to restore the original luster. Frequent polishing with a compound or an incorrect polishing technique will result in removing the paint layer and exposing the undercoat. When in doubt, it is always best to contact your SUBARU dealer or an auto paint specia-

list. NOTE Be careful not to block the windshield washer nozzles with wax when waxing the vehicle.
& Cleaning aluminum wheels . Promptly wipe the aluminum wheels clean of any kind of grime or agent. If dirt is left on too long, it may be difficult to clean off. . Do not use soap containing grit to clean the wheels. Be sure to use a neutral cleaning agent, and later rinse thoroughly with water. Do not clean the wheels with a stiff brush or expose them to a high-speed washing device. . Clean the vehicle (including the alumi- num wheels) with water as soon as possible when it has been splashed with sea water, exposed to sea breezes, or driven on roads treated with salt or other agents.

Corrosion protection
Your SUBARU has been designed and built to resist corrosion. Special materials and protective finishes have been used on most parts of the vehicle to help maintain fine appearance, strength, and reliable operation.
& Most common causes of
corrosion
The most common causes of corrosion are: 1. The accumulation of moisture retain- ing dirt and debris in body panel sections, cavities, and other areas. 2. Damage to paint and other protective coatings caused by gravel and stone chips or minor accidents.
Corrosion is accelerated on the vehicle when: 1. is exposed to road salt or dust It control chemicals, or used in coastal areas where there is more salt in the air, or in areas where there is considerable industrial pollution. 2. It is driven in areas of high humidity, especially when temperatures range just above freezing. 3. Dampness in certain parts of the vehicle remains for a long time, even
though other parts of the vehicle may be dry. 4. High temperatures will cause corro- sion to parts of the vehicle which cannot dry quickly due to lack of proper ventila- tion.
& To help prevent corrosion Wash the vehicle regularly to prevent corrosion of the body and suspension components. Also, wash the vehicle promptly after driving on any of the following surfaces: . roads that have been salted to prevent them from freezing in winter . mud, sand, or gravel . coastal roads
After the winter has ended, it is recom- mended that the underbody be given a very thorough washing.
Before the beginning of winter, check the condition of underbody components, such as the exhaust system, fuel and brake lines, brake cables, suspension, steering system, floor pan, and fenders. If any of them are found to be rusted, they should be given an appropriate rust prevention treatment or should be replaced. Contact your SUBARU dealer to perform this kind of maintenance and treatment if you need

assistance.
Repair chips and scratches in the paint as soon as you find them.
Check the interior of the vehicle for water and dirt accumulation under the floor mats because that could cause corrosion. Occasionally check under the mats to make sure the area is dry. Keep your garage dry. Do not park your vehicle in a damp, poorly ventilated garage. In such a garage, corrosion can be caused by dampness. If you wash the vehicle in the garage or put the vehicle into the garage when wet or covered with snow, that can cause dampness.
If your vehicle is operated in cold weather and/or in areas where road salts and other corrosive materials are used, the door hinges and locks, trunk lid lock, and hood latch should be inspected and lubricated periodically.

Cleaning the interior
Use a soft, damp cloth to clean the climate control panel, audio equipment, instru- ment panel, center console, combination meter panel, and switches. (Do not use organic solvents.)
& Seat fabric Remove loose dirt, dust or debris with a vacuum cleaner. If the dirt is caked on the fabric or hard to remove with a vacuum cleaner, use a soft brush then vacuum it. Wipe the fabric surface with a tightly wrung cloth and dry the seat fabric thoroughly. If the fabric is still dirty, wipe using a solution of mild soap and luke- warm water then dry thoroughly.
the stain does not come out,
try a If commercially-available fabric cleaner. Use the cleaner on a hidden place and make sure it does not affect the fabric adversely. Use the cleaner according to its instruc- tions. NOTE When cleaning the seat, do not use benzine, paint thinner, or any similar materials.
& Leather seat materials The leather used by SUBARU is a high quality natural product which will retain its distinctive appearance and feel for many years with proper care. Allowing dust or road dirt to build up on the surface can cause the material to become brittle and to wear prematurely. Regular cleaning with a soft, moist, natural fiber cloth should be performed monthly, taking care not to soak the leather or allow water to penetrate the stitched seams. A mild detergent suitable for cleaning woolen fabrics may be used to remove difficult dirt spots, rubbing with a soft, dry cloth afterwards to restore the luster. If your SUBARU is to be parked for a long time in bright sunlight, it is recommended that the seats and headrests be covered, or the windows shaded, to prevent fading or shrinkage. Minor surface blemishes or bald patches may be treated with a commercial leather spray lacquer. You will discover that each leather seat section will develop soft folds or wrinkles, which is characteristic of genuine leather.
& Synthetic leather upholstery The synthetic leather material used on the SUBARU may be cleaned using mild soap
Black plate (283,1)
Appearance care 10-5
or detergent and water, after first vacuum- ing or brushing away loose dirt. Allow the soap to soak in for a few minutes and wipe off with a clean, damp cloth. Commercial foam-type cleaners suitable for synthetic leather materials may be used when necessary. NOTE Strong cleaning agents such as sol- vents, paint thinners, window cleaner or gasoline must never be used on leather or synthetic interior materials.
& Climate control panel, audio
panel, instrument panel, console panel, and switches Use a soft, damp cloth to clean the climate control panel, audio equipment, instru- ment panel, center console, combination meter panel, and switches. NOTE Do not use organic solvents such as paint thinners or gasoline, or strong cleaning agents that contain those solvents.

guard against getting oil or fluids in your eyes. If something does get thoroughly wash them out with clean water. . Do not tamper with the wiring of the SRS airbag system or seat- belt pretensioner system, or at- tempt to take its connectors apart, as that may activate the system or it can render it inop- erative. The wiring and connec- tors 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, con- sult your nearest SUBARU deal- er.
& Before checking or servicing
in the engine compartment
WARNING
. Always stop the engine and set the parking brake firmly to pre- vent 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

Engine oil
NOTE . The engine oil consumption rate is not stabilized, and therefore cannot be determined until the vehicle has tra- veled at least several thousand miles (kilometers). Even after break-in, when the vehicle is used under severe driv- ing conditions such as those men- tioned in the Warranty and Mainte- nance Booklet, engine oil is consumed or deteriorated more quickly than un- der normal driving conditions. If you drive your vehicle under these severe conditions, you should check the oil level at least at every second fuel fill-up time, and change the oil more fre- quently. Please refer to the Warranty and Maintenance Booklet for more de- tails. . If the oil consumption rate seems abnormally high after the break-in period, for example more than 1 quart per 1,200 miles or 1 liter per 2,000
kilometers, we recommend that you contact your SUBARU dealer.& Checking the oil level Check the engine oil stop. 1. Park the vehicle on a level surface and stop the engine.

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.
CAUTION
. Use only engine oil with the recommended grade and vis- cosity.
. 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 “War- ranty and Maintenance Bookletâ€. 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 weather. 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.

Cooling system
WARNING
Never attempt to remove the radia- tor 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 boil- ing 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 pro- vides protection against freezing down to −338F (−368C). For add- ing, use genuine SUBARU cool- ant or an equivalent: a mixture of 50% soft water (or clear and drinkable water) and 50% phos- phate or non-amine type coolant. Use of improper coolants may result in corrosion in the cooling system. It is important to main- tain protection against freezing and corrosion, even if freezing
temperatures are not expected. Never mix different kinds of cool- ant.
. 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 con-
nections
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 tempera- ture 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 neces- sary, 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.

Automatic transmission fluid & Checking the fluid level The automatic transmission fluid expands largely as its temperature rises; the fluid level differs according to fluid temperature. Therefore, there are two different scales for checking the level of hot fluid and cold fluid on the dipstick.
Though the fluid level can be checked without warming up the fluid on the “COLD†range, we recommend checking the fluid level when the fluid is at operating temperature. ! Checking the fluid level when the
fluid is hot
1. Drive the vehicle several miles to raise the temperature of the transmission fluid up to normal operating temperature; 158
to 1768F (70 to 808C) is normal. 2. Park the vehicle on a level surface and set the parking brake. 3. First shift the selector lever in each position. Then shift it in the “P†position, and run the engine at idling speed.1) Yellow handle

4. Pull out the dipstick and check the fluid level on the gauge. If it is below the lower level on the “HOT†range, add the recom- mended automatic transmission fluid up to the upper level.
! Checking the fluid level when the
fluid is cold
When the fluid level has to be checked without time to warm up the automatic transmission, check to see that the fluid level is between the lower level and upper level on the “COLD†range. If it is below that range, add fluid up to the upper level. Be careful not to overfill.
CAUTION
Be careful not to spill automatic transmission fluid when adding it. If automatic transmission fluid touches the exhaust pipe, it may cause a bad smell, smoke, and/or a fire. If automatic transmission fluid gets on the exhaust pipe, be sure to wipe it off.

Tires and wheels & Types of tires You should be familiar with type of tires present on your vehicle. The factory-fitted 17-inch tires on the WRX-STI are summer tires. The factory- fitted tires on other versions are all-season tires. ! All season tires All season tires are designed to provide an adequate measure of traction, handling and braking performance in year-round driving including snowy and icy road conditions. However all season tires do not offer as much traction performance as winter (snow) tires in heavy or loose snow or on icy roads. All season tires are identified by “ALL SEASON†and/or “M+S†(Mud & Snow) on the tire sidewall. ! Summer tires Summer tires are high-speed capability tires best suited for highway driving under dry conditions. Summer tires are inadequate for driving on slippery roads such as on snow- covered or icy roads. If you drive your vehicle on snow-covered or icy roads, we strongly recommend the
use of winter (snow) tires. When installing winter tires, be sure to replace all four tires. ! Winter (snow) tires Winter tires are best suited for driving on snow-covered and icy roads. However winter tires do not perform as well as summer tires and all season tires on roads other than snow-covered and icy roads.
immedi-
& Tire inspection Check on a daily basis that the tires are free from serious damage, nails, and stones. At the same time, check the tires for abnormal wear. Contact your SUBARU dealer ately if you find any problem. NOTE . When the wheels and tires strike curbs or are subjected to harsh treat- ment as when the vehicle is driven on a rough surface, they can suffer damage that cannot be seen with the naked eye. This type of damage does not become evident until time has passed. Try not to drive over curbs, potholes or on other rough surfaces. If doing so is unavoidable, keep the vehicle’s speed down to a walking pace or less, and approach the curbs as squarely as
北米Model "A1920BE-B" EDITED: 2006/ 9/ 19
possible. Also, make sure the tires are not pressed against the curb when you park the vehicle. . If you feel unusual vibration while driving or find it difficult to steer the vehicle in a straight line, one of the tires and/or wheels may be damaged. Drive slowly to the nearest authorized SUBARU dealer and have the vehicle inspected.
& Tire pressures and wear Maintaining the correct tire pressures helps to maximize the tires’ service lives and is essential for good running perfor- mance. Check and, if necessary, adjust the pressure of each tire (including the spare) at least once a month (for example, during a fuel stop) and before any long journey.
Check the tire pressures when the tires are cold. Use a pressure gauge to adjust the tire pressures to the values shown on the tire placard. The tire placard is located on the door pillar on the driver’s side.
Driving even a short distance warms up the tires and increases the tire pressures. Also, the tire pressures are affected by the outside temperature. It is best to check tire pressure outdoors before driving the vehicle.
When a tire becomes warm, the air inside it expands, causing the tire pressure to increase. Be careful not to mistakenly release air from a warm tire to reduce its pressure.
Black plate (315,1)
Maintenance and service 11-31
NOTE . The air pressure in a tire increases by approximately 4.3 psi (30 kPa, 0.3
kgf/cm2) when the tire becomes warm. . The tires are considered cold when the vehicle has been parked for at least three hours or has been driven less than one mile (1.6 km).WARNING
Do not let air out of warm tires to adjust pressure. Doing so will result in low tire pressure.
Incorrect tire pressures detract from con- trollability and ride comfort, and they cause the tires to wear abnormally.
