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 “MIN” mark, add coolant up to the “MAX” 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. IMPREZA(NA) A1830BE-A (ENGLISH) In case of emergency Towing If towing is necessary, it is best done by your SUBARU dealer or a commercial towing service. Observe the following procedures for safety. HG9000BA 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 will cause the vehicle to spin away due to the – CONTINUED – 9-15 IMPREZA(NA) A1830BE-A (ENGLISH) In case of emergency operation or deterioration of the center differ- ential. Front towing eye: J Towing and tie-down eyes The towing eyes should be used only in an emer- gency (e.g., to free a stuck vehicle from mud, sand or snow). 9-16 HG9006BA 1. Take out the towing eye, screwdriver and wheel nut wrench from the on board tool bag. 2. Pry off the cover on the front bumper using a screwdriver, and you will find a threaded hole for at- taching the towing eye. 3. Screw the towing eye into the threaded hole until its thread can no longer be seen. 4. Tighten the towing eye securely with a wheel nut wrench. After towing, remove the towing eye from the vehicle and stow it in the tool bag. Put the threaded hole cover on the front bumper. WARNING D Do not use the towing eye except when tow- ing your vehicle. D Be sure to remove the towing eye after tow- ing. Leaving the towing eye mounted on the vehicle could interfere with proper operation of the SRS airbag system in a frontal collision. IMPREZA(NA) A1830BE-A (ENGLISH) In case of emergency Rear towing eye: HG9004CA CAUTION Do not apply excessive lateral load to the tow- ing eyes. – CONTINUED – 9-17 In case of emergency Tie-down eyes: HG9011BB 1) Tie-down eye 2) Towing and tie-down eye 9-18 IMPREZA(NA) A1830BE-A (ENGLISH) CAUTION Never use the tie-down eye on the underside of the vehicle closest to the muffler for towing purposes. J Using a flat-bed truck HG9002AA This is the best way to transport your vehicle. Use the following procedures to ensure safe transporta- 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. J Towing with all wheels on the ground IMPREZA(NA) A1830BE-A (ENGLISH) In case of emergency 1. 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. WARNING 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. HG9001AA – CONTINUED – 9-19 IMPREZA(NA) A1830BE-A (ENGLISH) In case of emergency CAUTION Maintenance tools 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 engine run- ning. 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. 9-20 HG9010AA Your vehicle is equipped with the following mainte- nance tools: Wheel cover remover (vehicles with wheel covers) Screwdriver Towing eye Wheel nut wrench IMPREZA(NA) A1830BE-A (ENGLISH) In case of emergency J Jack and jack handle HGS042BA The jack is stored on the left side of the trunk or cargo area.

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, it may be dam- aged by car wash brushes or other equipment. 10-2 IMPREZA(NA) A1830BE-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 recommended. Never use a coarse-grained com- IMPREZA(NA) A1830BE-A (ENGLISH) Appearance care 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. 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. 10 – CONTINUED – 10-3 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) A1830BE-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) A1830BE-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) A1830BE-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 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 Ensure your eyes are free of oil and fluid, as they can be harmful to your eyes. If you get one in your eyes, wash your eyes with clean water. For your safety, you are wise to wear eye protection. 11-4 IMPREZA(NA) A1830BE-A (ENGLISH) D Do not tamper with the wiring of the SRS 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 suddenly even when the engine is stopped. J When you do checking or servicing in the engine compartment while the engine is running 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.

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 Be careful not to burn yourself with hot en- gine oil. Maintenance and service 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. 11-10 5. Wipe the seating surface of the drain plug with a clean cloth and tighten it securely with a new seal- ing washer after the oil has completely drained out. HS0176 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. IMPREZA(NA) A1830BE-A (ENGLISH) Maintenance and service CAUTION Never over tighten the oil filter because that can result in an oil leak. 10.

The following table lists the recommended vis- cosities and applicable temperatures. When adding oil, different brands may be used to- gether as long as they are the same API classifica- tion 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 re- quired to properly lubricate the engine. IMPREZA(NA) A1830BE-A (ENGLISH) 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-inhibit- ing, 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 cool- ant. Use of improper coolants may result in corrosion in the cooling system. It is impor- tant to maintain protection against freezing and corrosion, even if freezing temperatures are not expected.

If the level is close to or lower than the “LOW” level mark, add coolant up to the “FULL” level mark. If the reserve tank is empty, remove the radiator cap and refill as required. Maintenance and service D Do not splash the engine coolant over painted parts. The alcohol contained in the en- gine coolant may damage the paint surface. J 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 ex- ceeds the normal operating range, the cooling fan circuit may be defective. Check the fuse and re- place it if necessary. If the fuse is not blown, have the cooling system checked by your SUBARU deal- er. If frequent addition of coolant is necessary, there may be a leak in the engine cooling system. It is rec- ommended that the cooling system and connections be checked for leaks, damage, or looseness. 11-14 IMPREZA(NA) A1830BE-A (ENGLISH) Maintenance and service 1) Rubber gaskets 1) Drain plug HG0115 HGA000BD 3.

J Types of tires B 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 have adequate traction performance compared with winter (snow) tires in heavy or loose snow or on icy road. All season tires are identified by “ALL SEASON” and/or “M+S” (Mud & Snow) on the tire sidewall. B 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. B Winter (snow) tires Winter tires are best suited for driving on snow-cov- – CONTINUED – 11-37 11 Maintenance and service ered and icy roads. However winter tires do not have adequate performance compared with sum- mer 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 other rough surface. If doing so is unavoidable, 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 not pressed against the curbs when you park the vehicle. D If you feel unusual vibration while driving or find it difficult to steer the vehicle in a straight 11-38 IMPREZA(NA) A1830BE-A (ENGLISH) 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. 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. HB0382 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) A1830BE-A (ENGLISH) Maintenance and service D Correct tire pressure (tread worn evenly) HGB033AA Roadholding is good, and steering is responsive. Rolling resistance is low, so fuel consumption is also lower. 11 – CONTINUED – 11-39 IMPREZA(NA) A1830BE-A (ENGLISH) Maintenance and service D Abnormally low tire pressure (tread worn at shoulders) D Abnormally high tire pressure (tread worn in center) HGB024AA HGB025AA 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. WARNING Driving at high speeds with excessively low tire pressures can cause the tires to deform severely and to rapidly become hot. A sharp 11-40 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 systems 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 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 IMPREZA(NA) A1830BE-A (ENGLISH) Maintenance and service
