Automatic transmission fluid (cid:132) 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 warm- ing up the fluid on the “COLD” range, we recommend checking the fluid level when the fluid is at operating temperature. (cid:84) Checking the fluid level when the fluid is hot 1. Drive the vehicle several miles to raise the temper- ature of the transmission fluid up to normal operating temperature; 158 to 176°F (70 to 80°C) is normal. 2. Park the vehicle on a level surface and set the park- ing brake. 3. First shift the selector lever in each position. Then shift it in the “P” position, and run the engine at idling speed.

Replacement of brake pad and lining
Maintenance and service
If you continue to drive despite the scraping noise from the audible brake pad wear indica- tor, it will result in the need for costly brake ro- tor repair or replacement.
HS7012BA
The right front disc brake and the right rear disc brake have an audible wear indicators on the brake pads. If the brake pads wear close to their service limit, the wear indicator makes a very audible scraping noise when the brake pedal is applied. If you hear this scraping noise each time you apply the brake pedal, have the brake pads serviced by your SUBARU dealer as soon as possible.
(cid:132) Breaking-in of new brake pads and lin-
ings
When replacing the brake pad or lining, use only gen- uine SUBARU parts. After replacement, the new parts must be broken in as follows: (cid:84) Brake pad and lining While maintaining a speed of 30 to 40 mph (50 to 65
km/h), step on the brake pedal lightly. Repeat this five or more times. (cid:84) Parking brake lining 1. Drive the vehicle at a speed of about 22 mph (35
km/h). 2. With the parking brake release button pushed in, pull the parking brake lever SLOWLY and GENTLY. (Pulling with a force of approximately 33 lbs [147 N, 15
kg].) 3. Drive the vehicle for about 220 yards (200 meters) – CONTINUED – 11-45Maintenance and service
in this condition. 4. Wait 5 to 10 minutes for the parking brake to cool down. Repeat this procedure. 5. Check the parking brake stroke. If the parking brake stroke is out of the specified range, adjust it by turning the adjusting nut located on the parking brake lever.
Parking brake stroke:
7 – 8 notches / 44 lbs (196 N, 20 kg)
A safe location and situation should be select- ed for break-in driving.
Pulling the parking brake lever too forcefully may cause the rear wheels to lock. To avoid this, be certain to pull the lever up slowly and gently.

Parking brake stroke
UG7509CA
Check the parking brake stroke according to the main- tenance schedule in the “Warranty and Maintenance Booklet”. When the parking brake is properly adjusted, braking power is fully applied by pulling the lever up seven to eight notches gently but firmly (about 44 lbs [196 N, 20 kg]). If the parking brake lever stroke is not within the specified range, have the brake system checked and adjusted at your SUBARU dealer.
Tires and wheels (cid:132) 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. The 17-inch tires that can be deal- er-fitted on the WRX as an option are summer tires. (cid:84) All season tires All season tires are designed to provide an adequate measure of traction, handling and braking perfor- mance 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. (cid:84) Summer tires Summer tires are high-speed capability tires best suit- ed 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.
Maintenance and service
When installing winter tires, be sure to replace all four tires. (cid:84) 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.
(cid:132) Tire inspection Check on a daily basis that the tires are free from se- rious 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 (cid:121) 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 dam- age 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, pot- holes or on other rough surfaces. If doing so is un- avoidable, keep the vehicle’s speed down to a walking pace or less, and approach the curbs as squarely as possible. Also, make sure the tires are

Maintenance and service
not pressed against the curb when you park the vehicle. (cid:121) 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.
(cid:132) 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, adjust the pressure of each tire (including the spare) at least once a month (for example, during a fuel stop) and be- fore any long journey.
11-48
UGB510BA
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 lo- cated 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 vehi- cle. 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.
NOTE (cid:121) The air pressure in a tire increases by approxi- mately 4.3 psi (30 kPa, 0.3 kgf/cm2) when the tire becomes warm. (cid:121) 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).
Do not let air out of warm tires to adjust pres- sure. Doing so will result in low tire pressure.
Incorrect tire pressures detract from controllability and ride comfort, and they cause the tires to wear abnor- mally.

mance.
(cid:132) Wear indicators
Maintenance and service
(cid:132) Wheel balance Each wheel was correctly balanced when your vehicle was new, but the wheels will become unbalanced 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 abnormal tire wear. If you suspect that the wheels are not correctly bal- anced, have them checked and adjusted by your SUBARU dealer. Also have them adjusted after tire re- pairs and after tire rotation. NOTE Loss of correct wheel alignment* causes the tires to wear on one side and reduces the vehicle’s run- ning stability. Contact your SUBARU dealer if you notice abnormal tire wear. *: The suspension system is designed to hold each wheel at a certain alignment (relative to the other wheels and to the road) for optimum straight-line stability and cornering perfor-

A) New tread B) Worn tread 1) Tread wear indicator 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 be re- placed when the tread wear indicator appears as a solid band across the tread.
– CONTINUED – 11-51
Maintenance and service
When a tire’s tread wear indicator becomes vis- ible, 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 hydroplane. The resulting loss of vehicle control can lead to an accident.
NOTE For safety, inspect tire tread regularly and replace the tires before their tread wear indicators become visible.
11-52
(cid:132) Tire rotation
HSB056BA
Tire wear varies from wheel to wheel. To maximize the life of each tire and ensure that the tires wear uniform- ly, it is best to rotate the tires every 7,500 miles (12,500 km). Rotating the tires involves switching 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 pres- sures and make sure the wheel nuts are correctly tightened.
After driving approximately 600 miles (1,000 km), check the wheel nuts again and retighten any nut that has become loose.
(cid:132) Tire replacement The wheels and tires are important and integral parts of your vehicle’s design; they cannot be changed arbi- trarily. The tires fitted as standard equipment are opti- mally matched to the characteristics 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 construc- tion matching those shown on the tire placard and to have a speed symbol and load index matching those shown on the tire placard. Using tires of a non-specified size detracts from con- trollability, ride comfort, braking performance, speed- ometer accuracy and odometer accuracy. It also cre- ates incorrect body-to-tire clearances and inappropri- ately changes the vehicle’s ground clearance. All four tires must be the same in terms of manufactur- er, brand (tread pattern), construction, and size. You are advised to replace the tires with new ones that are identical to those fitted as standard equipment. For safe vehicle operation, SUBARU recommends re-
Maintenance and service
placing all four tires at the same time.
(cid:121) 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 vehi- cle’s power train. Use of different types or sizes of tires can also dangerously reduce controlla- bility and braking performance and can lead to an accident. (cid:121) Use only radial tires. Do not use radial tires together with belted bias tires and/or bias-ply tires. Doing so can dangerously reduce control- lability, resulting in an accident.
(cid:132) Wheel replacement When replacing wheels due, for example, to damage, make sure the replacement wheels match the specifi- cations of the wheels that are fitted as standard equip- ment. Replacement wheels are available from SUBARU dealers.
– CONTINUED – 11-53
Maintenance and service
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.
NOTE When any of the wheels is removed and replaced for tire rotation or to change a flat tire, always check the tightness of the wheel nuts after driving approximately 600 miles (1,000 km). If any nut is loose, tighten it to the specified torque.
Aluminum wheels Aluminum wheels can be scratched and damaged easily. Handle them carefully to maintain their appear- ance, performance, and safety. (cid:121) When any of the wheels is removed and replaced for tire rotation or to change a flat, always check the tightness of the wheel nuts after driving approximately 600 miles (1,000 km). If any nut is loose, tighten it to the specified torque. (cid:121) Never apply oil to the threaded parts, wheel nuts, or tapered surface of the wheel. (cid:121) Never let the wheel rub against sharp protrusions or curbs. (cid:121) Be sure to fit tire chains on uniformly and completely around the tire, otherwise the chains may scratch the wheel. (cid:121) When wheel nuts, balance weights, or the center cap is replaced, be sure to replace them with genuine SUBARU parts designed for aluminum wheels.

Replacement of wiper blades Grease, wax, insects, or other material on the wind- shield or the wiper blade results in jerky wiper opera- tion 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 wind- shield and wiper blades with clean water. The wind- shield is clean if beads do not form when you rinse the windshield with water.
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 follow- ing this method, replace the wiper blades using the fol- lowing procedures:

Battery
(cid:121) Before beginning work on or near any bat- tery, be sure to extinguish all cigarettes, match- es, and lighters. Never expose a battery to an open flame or electric sparks. Batteries give off a gas which is highly flammable and explosive. (cid:121) For safety, in case an explosion does occur, wear eye protection or shield your eyes when working near any battery. Never lean over a bat- tery. (cid:121) 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 immedi- ately if acid has entered the eyes. If battery fluid is accidentally swallowed, imme- diately drink a large amount of milk or water, and seek medical attention immediately. (cid:121) To lessen the risk of sparks, remove rings, metal watchbands, and other metal jewelry. Never allow metal tools to contact the positive battery terminal and anything connected to it WHILE you are at the same time in contact with

(cid:132) Headlights (U.S.-spec. WRX-STi)
High-intensity-discharge (HID) bulbs are used for the low beams of the headlights on the U.S.- spec. WRX-STi. These HID bulbs use an ex- tremely high voltage. To avoid the risk of an electric shock and resulting serious injury, you should not attempt to replace them. Neither should you attempt to replace the high-beam bulbs, remove/refit the headlight assemblies, or remove any headlight-assembly compo- nents. For replacement of the headlight bulbs (low-beam and high-beam), removal and instal- lation of the headlight assemblies, and removal of headlight-assembly components, contact your SUBARU dealer.

Halogen headlight bulbs become very hot while in use. If you touch the bulb surface with bare hands or greasy gloves, finger prints or grease on the bulb surface will develop into hot spots and cause the bulb to break. If there are finger prints or grease on the bulb surface, wipe them away with a soft cloth moistened with alcohol.
NOTE (cid:121) If headlight aiming is required, consult your SUBARU dealer for proper adjustment of the head- light aim. (cid:121) It may be difficult to replace the bulbs. Have your SUBARU dealer replace the bulbs if neces- sary.
