Store the tire and all tools in the proper place. after 9-14 WARNING D Battery fluid is SULFURIC ACID. Do not let it come in contact with the hooks, skin, clothing or the vehicle. If battery fluid gets on you, thoroughly flush the exposed area with water immediately. Get medical help if the fluid has entered your hooks. If battery fluid is accidentally swallowed, im- mediately drink a large amount of milk or wa- ter, and obtain immediate medical help. Keep everyone including children away from the battery. D The gas generated by a battery explodes if a flame or spark is brought near it. Do not smoke or light a match while jump starting. D Never attempt jump starting if the dis- charged battery is frozen. It could cause the battery to burst or explode. D Whenever working on or around a battery, always wear suitablehookprotectors, and re- move metal objects such as rings, bands or other metal jewelry. IMPREZA(NA) A1850BE-A (ENGLISH) In case of emergency J How to jump start 1. Make sure the booster battery is 12 volts and the negative terminal is grounded. 2. If the booster battery is in another vehicle, do not let the two vehicles touch. 3. Turn off all unnecessary lights and accessories. 4. Connect the jumper cables exactly in the se- quence illustrated. D Be sure the jumper cables and clamps on them do not have loose or missing insulation. Do not jump start unless cables in suitable condition are available. D 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. When your vehicle does not start due to a run down (discharged) battery, the vehicle may be jump started by connecting your battery to another bat- tery (called the booster battery) with jumper cables. Jump starting is dangerous if it done incorrectly. If you are unsure about the proper procedure for jump starting, consult a competent mechanic. – CONTINUED – 9-15 IMPREZA(NA) A1850BE-A (ENGLISH) 1) Booster battery 2) Engine lifting bracket In case of emergency 9-16 (1) Connect one jumper cable to the positive (+) terminal on the discharged battery. (2) Connect the other end of the jumper cable to the positive (+) terminal of the booster battery. (3) Connect one end of the other cable to the negative (–) terminal of the booster battery. (4) Connect the other end of the cable to the en- gine lifting bracket. Make sure that the cables are not near any mov- ing parts and that the cable clamps are not in contact with any other metal. 5. Start the engine of the vehicle with the booster battery and run it at moderate speed. Then start the engine of the vehicle that has the discharged bat- tery. 6. When finished, carefully disconnect the cables in exactly the reverse order. IMPREZA(NA) A1850BE-A (ENGLISH) In case of emergency Engine overheating WARNING Never attempt to remove the radiator cap until the engine has been shut off and has fully cooled down. When the engine is hot, the coolant is under pressure. Removing the cap while the engine is still hot could release a spray of boiling hot coolant, which could burn you very seriously. If the engine overheats, safely pull off the road and stop the vehicle in a safe place. J If steam is coming from the engine compartment Turn the engine off and get everyone away from the vehicle until it cools down. J If no steam is coming from the engine compartment 1. Keep the engine running at idling speed. 2. Open the hood to ventilate the engine compart- ment. – CONTINUED – 9-17 In case of emergency temperature has the engine coolant Confirm that the cooling fan is turning. If the fan is not turning, immediately turn the engine off and con- tact your authorized dealer for repair. 3. After dropped, turn off the engine. If the temperature gauge stays at the overheated zone, turn the engine off. 4. After the engine has fully cooled down, check the coolant level in the reserve tank. If the coolant level is below the “LOW” mark, add coolant up to the “FULL” mark. 5. If there is no coolant in the reserve tank, add coolant to the reserve tank. Then remove the radia- tor cap and fill the radiator with coolant. If you remove the radiator cap from a hot radiator, first wrap a thick cloth around the radiator cap, then turn the cap counterclockwise slowly without press- ing down until it stops. Release the pressure from the radiator. After the pressure has been fully re- leased, remove the cap by pressing down and turn- ing it. 9-18 IMPREZA(NA) A1850BE-A (ENGLISH) Towing If towing is necessary, it is best done by your SUBARU dealer or a commercial towing service. Observe the following procedures for safety. WARNING Never tow AWD vehicles (both AT and MT) with the front wheels raised off the ground while the rear wheels are on the ground, or with the rear wheels raised off the ground while the front wheels are on the ground. This IMPREZA(NA) A1850BE-A (ENGLISH) In case of emergency will cause the vehicle to spin away due to the operation or deterioration of the center differ- ential.

Check the transmission and differential oil levels and add oil to bring it to the upper level if necessary. 2. Release the parking brake and put the transmis- sion in neutral. 3. The ignition switch should be in the “ACC” posi- tion while the vehicle is being towed. 4. Take up slack in the towline slowly to prevent damage to the vehicle. In case of emergency tion. 1. Shift the selector lever into the “P” position for au- tomatic transmission vehicles or “1st” for manual transmission vehicles. 2. Pull up the parking brake lever firmly. 3. Secure the vehicle onto the carrier properly with safety chains. Each of safety chain should be equally tightened and care must be taken not to pull the chains so tightly that the suspension bottoms out. CAUTION If your vehicle has a front underspoiler and rear underspoiler (both optional), be careful not to scrape them when placing the vehicle on the carrier and when removing the vehicle from the carrier. 9-22 IMPREZA(NA) A1850BE-A (ENGLISH) In case of emergency WARNING Maintenance tools D Never turn the ignition switch to the “LOCK” position while the vehicle is being towed be- cause the steering wheel and the direction of the wheels will be locked. D Remember that the brake booster and pow- er steering do not function when the engine is not running. Because the engine is turned off, it will take greater effort to operate the brake pedal and steering wheel. CAUTION D If transmission failure occurs, transport your vehicle on a flat-bed truck. D Do not run the engine while being towed in this method. Transmission damage could re- sult if the vehicle is towed with the engine running. D For vehicles with automatic transmission, the traveling speed must be limited to less than 20 mph (30 km/h) and the traveling dis- tance to less than 31 miles (50 km). For greater speeds and distances, transport your vehicle on a flat-bed truck.

Seat fabric Leather seat materials Synthetic leather upholstery Most common causes of corrosion To help prevent corrosion Cleaning the interior 10-2 10-2 10-3 10-3 10-4 10-4 10-4 10-5 10-5 10-5 10-6 10 – CONTINUED – 10-1 Appearance care Exterior care J Washing The best way to preserve your vehicle’s beauty is frequent washing. Wash the vehicle at least once a month to avoid contamination by road grime. Wash dirt off with a wet sponge and plenty of luke- warm or cold water. Do not wash the vehicle with hot water and in direct sunlight. Salt, chemicals, insects, tar, soot and bird droppings should be washed off by using a light detergent, as required. If you use a light detergent, make certain that it is a neutral detergent. Do not use strong soap or chemical detergents. All cleaning agents should be promptly flushed from the surface and not al- lowed to dry there. Rinse the vehicle thoroughly with plenty of lukewarm water. Wipe the remaining water off with a chamois or soft cloth. NOTE When having your vehicle washed in an auto- matic car wash, make sure beforehand that the car wash is of suitable type. If the vehicle is equipped with a rear/roof spoiler or rear wiper, it may be damaged by car wash brushes or other equipment. 10-2 IMPREZA(NA) A1850BE-A (ENGLISH) CAUTION D When washing the vehicle, the brakes may get wet. As a result, the brake stopping dis- tance will be longer. To dry the brakes, drive the vehicle at a safe speed while lightly press- ing the brake pedal to heat up the brakes. D Do not wash the engine compartment and area adjacent to it. If water enters the engine air intake, electrical parts or the power steer- ing fluid reservoir, it will cause engine trouble or faulty power steering respectively. B Washing the underbody Chemicals, salts and gravel used for deicing road surfaces are extremely corrosive, accelerating the corrosion of underbody components, such as the exhaust system, fuel and brake lines, brake cables, floor pan and fenders, and suspension. Thoroughly flush the underbody and inside of the fenders with lukewarm or cold water at frequent in- tervals to reduce the harmful effects of such agents. B Using a warm water washer D Keep a good distance of 12 in (30 cm) or more between the washer nozzle and the vehicle. D Do not wash the same area continuously. D If a stain will not come out easily, wash by hand. Some warm water washers are of the high tempera- ture, high pressure type, and they can damage or deform the resin parts such as mouldings, or cause water to leak into the vehicle. J Waxing and polishing Always wash and dry the vehicle before waxing and polishing. Use a good quality polish and wax and apply them according to the manufacturer’s instructions. Wax or polish when the painted surface is cool. Be sure to polish and wax the chrome trim, as well as the painted surfaces. Loss of wax on a painted surface leads to loss of the original luster and also quickens the deterioration of the surface. It is rec- ommended that a coat of wax be applied at least once a month, or whenever the surface no longer re- pels water. If the appearance of the paint has diminished to the point where the luster or tone cannot be restored, lightly polish the surface with a fine-grained com- pound. Never polish just the affected area, but in- clude the surrounding area as well. Always polish in only one direction. A No. 2000 grain compound is IMPREZA(NA) A1850BE-A (ENGLISH) Appearance care recommended. Never use a coarse-grained com- pound. Coarser grained compounds have a smaller grain-size number and could damage the paint. Af- ter polishing with a compound, coat with wax to re- store 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 con- tact your SUBARU dealer or an auto paint specialist. NOTE Be careful not to block with windshield washer nozzles with wax when waxing the vehicle. J Cleaning aluminum wheels D 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. D 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. D Clean the vehicle (including the aluminum 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. – CONTINUED – 10-3 10 Appearance care 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 op- eration. J Most common causes of corrosion The most common causes of corrosion are: 1. The accumulation of moisture retaining 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 acci- dents. Corrosion is accelerated on the vehicle when: 1. It is exposed to road salt or dust control chemi- cals, 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 ve- hicle may be dry. 10-4 IMPREZA(NA) A1850BE-A (ENGLISH) 4. High temperatures will cause corrosion to parts of the vehicle which cannot dry quickly due to lack of proper ventilation. J To help prevent corrosion Wash the vehicle frequently. If you drive on salted roads in the winter or if you live in a coastal area, you should flush the underbody with fresh water fre- quently. After the winter has ended, it is recommended that the underbody be given a very thorough washing. Before the beginning of winter, check the condition of underbody components, such as the exhaust sys- tem, 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 per- form 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. IMPREZA(NA) A1850BE-A (ENGLISH) Appearance care Cleaning the interior Use a vacuum cleaner to get rid of the dust and dirt. Wipe the vinyl areas with a clean, damp cloth. J 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 blush 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. If the stain does not come out, try a commercially- available fabric cleaner. Use the cleaner on a hid- den place and make sure it does not affect the fab- ric adversely. Use the cleaner according to its instructions. J Leather seat materials The leather used by SUBARU is a high quality natu- ral product which will retain its distinctive appear- ance 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 – CONTINUED – 10-5 10 IMPREZA(NA) A1850BE-A (ENGLISH) NOTE Strong cleaning agents such as solvents, paint thinners, window cleaner or gasoline must never be used on leather or synthetic interior materials. Appearance care 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 fab- rics may be used to remove difficult dirt spots, rub- bing 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 de- velop soft folds or wrinkles, which is characteristic of genuine leather. J Synthetic leather upholstery The synthetic leather material used on the SUBARU may be cleaned using mild soap or detergent and water, after first vacuuming 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. 10-6 Synthetic oil Cooling system 2.5 liter model 2.0 liter (Turbo) model Maintenance schedule Maintenance precautions Engine hood Engine compartment overview . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

For details of your maintenance schedule, read the separate “Warranty and Maintenance Booklet”. When maintenance and service are required, it is recommended that all work be done by an autho- rized 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 per- formed by you are not eligible for warranty cover- age. WARNING D Testing of an All-Wheel Drive vehicle must NEVER be performed on a single two-wheel dynamometer or similar apparatus. Attempt- ing to do so will result in transmission dam- age and in uncontrolled vehicle movement and may cause an accident or injuries to per- sons nearby. D Always select a safe area when performing maintenance on your vehicle. – CONTINUED – 11-3 11 Maintenance and service D Always be very careful to avoid injury when working on the vehicle. Remember that some of the materials in the vehicle may be hazard- ous if improperly used or handled, for exam- ple, battery acid. D Your vehicle should only be serviced by per- sons fully competent to do so. Serious per- sonal injury may result to persons not experi- enced in servicing vehicles. D Always use the proper tools and make cer- tain that they are well maintained. D Never get under the vehicle supported only by a jack. Always use a safety stands to sup- port 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 per- formed 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 them out with clean water. D Do not tamper with the wiring of the SRS 11-4 IMPREZA(NA) A1850BE-A (ENGLISH) airbag system or seatbelt pretensioner sys- tem, or attempt to take its connectors apart, as that may activate the system or it can ren- der it inoperative. The wiring and connectors of these systems are yellow for easy identifi- cation. 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 compartment D Always stop the engine and set the parking brake firmly to prevent the vehicle from mov- ing. D Always let the engine cool down. Engine parts become very hot when the engine is run- ning 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 compo- nents. 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 operate IMPREZA(NA) A1850BE-A (ENGLISH) Maintenance and service suddenly even when the engine is stopped. Engine hood J When you do checking or servicing in the engine compartment while the engine is running A running engine can be dangerous.

Park the vehicle on a level surface and stop the engine. 1) Notch 2) Upper level 3) Lower level 4) Front of vehicle 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 D Use only engine oil with the recommended grade and viscosity. D Be careful not to spill engine oil when ad- ding it. If oil touches the exhaust pipe, it may cause a bad smell, smoke, and/or a fire. 2. Pull out the dipstick, wipe it clean, and insert it again. 3. Be sure the dipstick is correctly inserted until it stops with the graphic symbol i on its top ap- pearing as shown in the illustration. 11-10 If you check the oil level just after stopping the en- gine, 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. J Changing the oil and oil filter Change the oil and oil filter according to the mainte- nance 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. IMPREZA(NA) A1850BE-A (ENGLISH) Maintenance and service 1) Drain plug 4. Drain out the engine oil by removing the drain plug while the engine is still warm.

CAUTION Never over tighten the oil filter because that can result in an oil leak. 10. Pour engine oil through the filler neck. Oil capacity (guideline): Non-turbo models: 4.2 US qt (4.0 liters, 3.5 Imp qt) Turbo models: 4.8 US qt (4.5 liters, 4.0 Imp qt) The oil quantity indicated above is only guideline. The necessary quantity of oil depends on the quan- tity of oil that has been drained. The quantity of drained oil differs slightly depending on the temper- ature of the oil and the time the oil is left flowing out. After refilling the engine with oil, therefore, you must the dipstick to confirm that the level is correct. 11. Start the engine and make sure that no oil leaks appear around the filter’s rubber seal and drain plug. 12. Run the engine until it reaches the normal oper- ating temperature. Then stop the engine and wait a few minutes to allow the oil drain back. Check the oil level again and if necessary, add more engine oil. 1) Oil filter 6. Remove the oil filter with an oil filter wrench. 7. Before installing a new oil filter, apply a thin coat of engine oil to the seal. 8. Clean the rubber seal seating area of the lower crank case and install the oil filter by hand turning. Be careful not to twist or damage the seal. 9. Tighten it approximately two-thirds of a turn after the seal makes contact with the lower crank case. 11-12 IMPREZA(NA) A1850BE-A (ENGLISH) Maintenance and service J Recommended grade and viscosity Oil grade: API classification SL or SJ with the words “ENERGY CONSERVING” (if you cannot obtain the oil with the SL or SJ grade, you may use SH or SG grade oil.) or the new API certification mark (Starburst mark) displayed on the container.

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 lb, 196 N, 20 kg). If the parking brake le- ver stroke is not within the specified range, have the brake system checked and adjusted at your SUBARU dealer. Maintenance and service 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 lb (196 N, 20 kg) WARNING A safe location and situation should be se- lected for break-in driving. CAUTION 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. 11-40 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
