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 un- necessary to clean or wash the 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.

Automatic transmission fluid

J 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 differ- ent 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 rec- ommend checking the fluid level when the fluid is at operating temperature. B Checking the fluid level when the fluid is hot Check the fluid level monthly. 1. Drive the vehicle several miles to raise the tem- perature of the transmission fluid up to normal oper- ating temperature; 158 to 176°F (70 to 80°C) is nor- mal. 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 id- ling speed.

Tires and wheels

J Types of tires You should be familiar with type of tires present on your vehicle. B All season tires The factory-installed tires on your new vehicle are all season tires. All season tires are designed to provide an ade- quate 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. B Summer tires The optional, dealer-installed, 17-inch tires recom- mended for the WRX are 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

IMPREZA(NA) A1850BE-A (ENGLISH)

Maintenance and service

(snow) tires. When installing winter tires, be sure to replace all four tires. B Winter (snow) tires Winter tires are best suited for driving on snow-cov- ered and icy roads. However winter tires do not per- form as well as summer tires and all season tires on roads other than snow-covered and icy roads.

J 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 immediately if you find any problem. NOTE D When the wheels and tires strike curbs or are subjected to harsh treatment 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 ap-

– CONTINUED – 11-41

11

Maintenance and service

proach the curbs as squarely as possible. Also, make sure the tires are not pressed against the curb when you park the vehicle. D 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 dam- aged. Drive slowly to the nearest authorized SUBARU dealer and have the vehicle inspected.

J Tire pressures and wear Maintaining the correct tire pressures helps to maxi- mize the tires’ service lives and is essential for good running performance. Check and, if necessary, ad- just the pressure of each tire (including the spare) at least once a month (for example, during a fuel stop) and before any long journey.

11-42

IMPREZA(NA) A1850BE-A (ENGLISH)

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 plac- ard 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 pres- sures are affected by the ambient temperature. It is best to check tire pressure outdoors before driving the vehicle. When a tire becomes warm, the air inside it ex- pands, causing the tire pressure to increase. Be careful not to mistakenly release air from a warm tire to reduce its pressure.

NOTE D The air pressure in a tire increases by approxi- mately 4.3 psi (30 kPa, 0.3 kg/cm2) when the tire becomes warm. D 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 pressrue. Doing so will result in low tire pres- sure.

Incorrect tire pressures detract from controllability and ride comfort, and they cause the tires to wear abnormally.

IMPREZA(NA) A1850BE-A (ENGLISH)

Maintenance and service

D Correct tire pressure (tread worn evenly)

Roadholding is good, and steering is responsive. Rolling resistance is low, so fuel consumption is also lower.

IMPREZA(NA) A1850BE-A (ENGLISH)

Maintenance and service

D Abnormally low tire pressure (tread worn at shoulders)

D Abnormally high tire pressure (tread worn in center)

Rolling resistance is high, so fuel consumption is also higher.

Ride comfort is poor. Also, the tire magnifies the effects of road-surface bumps and dips, possibly resulting in vehicle damage.

If the tire placard shows tire pressures for the ve- hicle when fully loaded and for the vehicle when towing a trailer, adjust the tire pressures to the val- ues that match current loading conditions.

11-44

WARNING

Driving at high speeds with excessively low tire pressures can cause the tires to deform severely and to rapidly become hot. A sharp increase in temperature could cause tread separation, and destruction of the tires. The resulting loss of vehicle control could lead to an accident.

J Wheel balance Each wheel was correctly balanced when your ve- hicle was new, but the wheels will become unbal- anced as the tires become worn during use. Wheel imbalance causes the steering wheel to vibrate slightly at certain vehicle speeds and detracts from the vehicle’s straight-line stability. It can also cause steering and suspension system problems and ab- normal tire wear. If you suspect that the wheels are not correctly balanced, have them checked and ad- justed by your SUBARU dealer. Also have them ad- justed after tire repairs and after tire rotation. NOTE Loss of correct wheel alignment* causes the tires to wear on one side and reduces the ve- hicle’s running stability. Contact your SUBARU

IMPREZA(NA) A1850BE-A (ENGLISH)

Each tire incorporates a tread wear indicator, which becomes visible when the depth of the tread grooves decreases to 0.063 in. (1.6 mm). A tire must – CONTINUED – 11-45

IMPREZA(NA) A1850BE-A (ENGLISH)

Maintenance and service

be replaced when the tread wear indicator appears as a solid band across the tread.

J Tire rotation

WARNING

When a tire’s tread wear indicator becomes visible, the tire is worn beyond the acceptable limit and must be replaced immediately. With a tire in this condition, driving at high speeds in wet weather can cause the vehicle to hydro- plane. The resulting loss of vehicle control can lead to an accident.

NOTE For safety, inspect tire tread regularly and re- place the tires before their tread wear indicators become visible.

11-46

Tire wear varies from wheel to wheel. To maximize the life of each tire and ensure that the tires wear uniformly, it is best to rotate the tires every 7,500
miles (12,500 km). Rotating the tires involves switch- ing the front and rear tires on the right-hand side of the vehicle and similarly switching the front and rear tires on the left-hand side of the vehicle. (Each tire must be kept on its original side of the vehicle.) Replace any damaged or unevenly worn tire at the time of rotation. After tire rotation, adjust the tire pressures and make sure the wheel nuts are cor- rectly tightened.

After driving approximately 600 miles (1,000 km), check the wheel nuts again and retighten any nut that has become loose.

J Tire replacement The wheels and tires are important and integral parts of your vehicle’s design; they cannot be changed arbitrarily. The tires fitted as standard equipment are optimally matched to the characteris- tics of the vehicle and were selected to give the best possible combination of running performance, ride comfort, and service life. It is essential for every tire to have a size and construction matching those shown on the tire placard and to have a speed sym- bol and load index matching those shown on the tire placard. Using tires of a non-specified size detracts from controllability, ride comfort, braking performance, speedometer accuracy and odometer accuracy. It also creates incorrect body-to-tire clearances and inappropriately changes the vehicle’s ground clear- ance. All four tires must be the same in terms of manufac- turer, brand (tread pattern), construction, and size. You are advised to replace the tires with new ones that are identical to those fitted as standard equip-

IMPREZA(NA) A1850BE-A (ENGLISH)

Maintenance and service

ment. For safe vehicle operation, SUBARU recommends replacing all four tires at the same time. NOTE

Unidirectional tires: Some tires have a specified direction of rotation. A tire of this type has an ar- row or other mark on its side wall to indicate the direction of rotation. Install it so that the direc- tion of rotation is correct when the vehicle is driven forward.

IMPREZA(NA) A1850BE-A (ENGLISH)

Maintenance and service

WARNING

D All four tires must be the same in terms of manufacturer, brand (tread pattern), construc- tion, degree of wear, speed symbol, load index and size. Mixing tires of different types, sizes or degrees of wear can result in damage to ve- hicle’s power train. Use of different types or sizes of tires can also dangerously reduce controllability and braking performance and can lead to an accident. D Use only radial tires. Do not use radial tires together with belted bias tires and/or bias-ply tires. Doing so can dangerously reduce con- trollability, resulting in an accident.

J Wheel replacement When replacing wheels due, for example, to dam- age, make sure the replacement wheels match the specifications of the wheels that are fitted as stan- dard equipment. Replacement wheels are available from SUBARU dealers.

WARNING

Use only those wheels that are specified for your vehicle. Wheels not meeting specifica- tions could interfere with brake caliper opera- tion and may cause the tires to rub against the wheel well housing during turns. The resulting loss of vehicle control could lead to an acci- dent.

Maintenance and service

Replacement of windshield wiper blades

Grease, wax, insects, or other material on the wind- shield or the wiper blade results in jerky wiper operation and streaking on the glass. If you cannot remove the streaks after operating the windshield washer or if the wiper operation is jerky, clean the outer surface of the windshield (or rear window) and the wiper blades using a sponge or soft cloth with a neutral detergent or mild-abrasive cleaner. After cleaning, rinse the windshield and wiper blades with clean water. The windshield is clean if beads do not form when you rinse the windshield with water.

CAUTION

Do not clean the wiper blades with gasoline or a solvent, such as paint thinner or benzene. This will cause deterioration of the wiper blades.

If you cannot eliminate the streaking even after fol- lowing this method, replace the wiper blades using the following procedures: 1. Raise the wiper arm off the windshield.

Battery

WARNING

D Before beginning work on or near any bat- tery, be sure to extinguish all cigarettes, matches, and lighters. Never expose a battery to an open flame or electric sparks. Batteries give off a gas which is highly flammable and explosive. D For safety, in case an explosion does occur, wear eye protection or shield your eyes when working near any battery. Never lean over a battery. D Do not let battery fluid contact eyes, skin, fabrics, or paint because battery fluid is a cor- rosive acid. If battery fluid gets on your skin or in your eyes, immediately flush the area with water thoroughly. Seek medical help im- mediately if acid has entered the eyes. If battery fluid is accidentally swallowed, immediately drink a large amount of milk or water, and seek medical attention immediately. D To lessen the risk of sparks, remove rings, metal watchbands, and other metal jewelry. Never allow metal tools to contact the positive

1) Stopper

Be sure to position the claws at the end of the metal support between the stoppers on the rubber as shown. If the rubber is not retained properly, the wiper blade may scratch the windshield. 6. Install the wiper blade assembly to the wiper arm. Make sure that it locks in place. 7. Slowly lower the arm in position.

battery terminal and anything connected to it WHILE you are at the same time in contact with any other metallic portion of the vehicle because a short circuit will result. D Keep everyone from the battery. D Charge the battery in a well-ventilated area. D Battery posts, terminals and related acces- sories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

Fuses

CAUTION

Never replace a fuse with one having a higher rating or with material other than a fuse be- cause serious damage or a fire could result.

The fuses are designed to melt during an overload to prevent damage to the wiring harness and electri- cal equipment. The fuses are located in two fuse boxes.

4. Pull out the fuse with the fuse puller. 5. Inspect the fuse. If it has blown, replace it with a spare fuse of the same rating. 6. If the same fuse blows again, this indicates that its system has a problem. Contact your SUBARU dealer for repairs.

Main fuse box

The main fuses are designed to melt during an over- load to prevent damage to the wiring harness and electrical equipment. Check the main fuses if any electrical component fails to operate (except the starter motor) and other fuses are good. A melted main fuse must be replaced. Use only replacements with the same specified rating as the melted main fuse. If a main fuse blows after it is replaced, have the electrical system checked by your nearest SUBARU dealer.
