2002 Subaru Impreza Owners Manual

For more information about the safety chain connec- tion, refer to the instructions for your hitch and trailer.

WARNING

Always use safety chains between your ve- hicle and the trailer. Towing trailer without safety chains could create a traffic safety haz- ard if the trailer separates from the hitch due to coupling damage or hitch ball damage.

Driving tips

B Side mirrors

HB0085

After hitching a trailer to your vehicle, check that the standard side mirrors provide a good rearward field of view without significant blind spots. If significant blind spots occur with the vehicle’s standard side mirrors, use towing mirrors that conform with Fed- eral, state/province and/or other applicable regula- tions. B Trailer lights Connection of trailer lights to your vehicle’s electrical system requires modifications to the vehicle’s light- ing circuit to increase its capacity and accommo- date wiring changes. To ensure the trailer lights are connected properly, please consult your SUBARU

8-34

IMPREZA(NA) A1830BE-A (ENGLISH)

dealer. Check for proper operation of the turn sig- nals, the brake lights and parking lights each time you hitch up.

CAUTION

Direct splicing or other improper connection of trailer lights may damage your vehicle’s electrical system and cause a malfunction of your vehicle’s lighting system.

B Tires Make sure that all the tires on your vehicle are prop- erly inflated to the pressure specified on the tire placard located on the left center pillar of your ve- hicle. Trailer tire condition, size, load rating and proper inflation pressure should be in accordance with the trailer manufacturer’s specifications. In the event your vehicle gets a flat tire when towing a trailer, ask a commercial road service to repair the flat tire. If you carry a regular size spare tire in your vehicle or trailer as a precaution against getting a flat tire, be sure that the spare tire is firmly secured.

WARNING

Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load. Use of the temporary spare tire when towing can result in failure of the spare tire and/or less stability of the vehicle.

J Trailer towing tips

CAUTION

D Never exceed 45 mph (72 km/h) when tow- ing a trailer in hilly country on hot days. D When towing a trailer, steering, stability, stopping distance and braking performance will be different from normal operation. For safety’s sake, you should employ extra cau- tion when towing a trailer and you should never speed. You should also keep the follow- ing tips in mind:

B Before starting out on a trip D Check that the vehicle and vehicle-to-hitch mount- ing are in good condition. If any problems are

IMPREZA(NA) A1830BE-A (ENGLISH)

Driving tips

apparent, do not tow the trailer. D Check that the vehicle sits horizontally with the trailer attached. If the vehicle is tipped sharply up at the front and down at the rear, check the total trailer weight, GVW, GAWs and tongue load again, then confirm that the load and its distribution are accept- able. D Check that the tire pressures are correct. D Check that the vehicle and trailer are connected properly. Confirm that.

– the trailer tongue is connected properly to the hitch ball. – the trailer lights connector is connected prop- erly and trailer’s brake lights illuminate when the vehicle’s brake pedal is pressed, and that the trail- er’s turn signal lights flash when the vehicle’s turn signal lever is operated. – the safety chains are connected properly. – all cargo in the trailer is secured safety in posi- tion. – the side mirrors provide a good rearward field of view without a significant blind spot.

D Sufficient time should be taken to learn the “feel” of the vehicle/trailer combination before starting out on a trip. In an area free of traffic, practice turning, stopping and backing up.

– CONTINUED – 8-35

Driving tips

B Driving with a trailer D You should allow for considerably more stopping distance when towing a trailer. Avoid sudden brak- ing because it may result in skidding or jackknifing and loss of control. D Avoid abrupt starts and sudden accelerations. If your vehicle has a manual transmission, always start out in first gear and release the clutch at moderate engine revolution. D Avoid uneven steering, sharp turns and rapid lane changes. D Slow down before turning. Make a longer than normal turning radius because the trailer wheels will be closer than the vehicle wheels to the inside of the turn. In a tight turn, the trailer could hit your vehicle. D Crosswinds will adversely affect the handling of your vehicle and trailer, causing sway. Crosswinds can be due to weather conditions or the passing of large trucks or buses. If swaying occurs, firmly grip the steering wheel and slow down immediately but gradually. D When passing other vehicles, considerable dis- tance is required because of the added weight and length caused by attaching the trailer to your vehicle. D Backing up with a trailer is difficult and takes practice. When backing up with a trailer, never

8-36

IMPREZA(NA) A1830BE-A (ENGLISH)

accelerate or steer rapidly. When turning back, grip the bottom of the steering wheel with one hand and turn it to the left for a left turn, and turn it to the right for a right turn.

immediately by

D If the ABS warning light illuminates while the vehicle is in motion, stop towing the trailer and have repairs performed the nearest SUBARU dealer. B Driving on grades D Before going down a steep hill, slow down and shift into lower gear (if necessary, use 1st gear) in order to utilize the engine braking effect and prevent overheating of your vehicle’s brakes. Do not make

temperature gauge pointer

sudden downshifts. D When driving uphill in hot weather, the air condi- tioner may turn off automatically to protect the engine from overheating. D When driving uphill in hot weather, pay attention to the water (for all vehicles) and AT OIL TEMP warning light (for AT vehicles) since the engine and transmission are rel- atively prone to overheating under these conditions. If the water temperature gauge pointer approaches the OVERHEAT zone or the AT OIL TEMP warning light illuminates, immediately switch off the air condi- tioner and stop the vehicle at the nearest safe place. Refer to the “Engine overheat” section in chapter 9, and “Warning and indicator lights” section in chap- ter 3. D If your vehicle has a automatic transmission, avoid using the accelerator pedal to stay stationary on an uphill slope instead of using the parking brake or foot brake. That may cause the transmission fluid to overheat. Also, if your vehicle is equipped with an automatic transmission, avoid driving with the gear selector lever in “D” when towing a heavy trailer to prevent fluid overheating. B Parking on a grade Always block the wheels under both vehicle and trailer when parking. Apply the parking brake firmly.

IMPREZA(NA) A1830BE-A (ENGLISH)

Driving tips

You should not park on a hill or slope. But if parking on a hill or slope cannot be avoided, you should take the following steps: 1. Apply the brakes and hold the pedal down. 2. Have someone place wheel blocks under both the vehicle and trailer wheels. 3. When the wheel blocks are in place, release the regular brakes slowly until the blocks absorb the load. 4. Apply the regular brakes and then apply the parking brake; slowly release the regular brakes. 5. Shift into 1st or reverse gear (manual transmis- sion) or “P” (automatic transmission) and shut off the engine.

WARNING

Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load. Use of the temporary spare tire when towing can result in failure of the spare tire and/or less stability of the vehicle and may lead to an accident.

The temporary spare tire is smaller and lighter than a conventional tire and is designed for emergency use only. Remove the temporary spare tire and re- install the conventional tire as soon as possible be- cause the spare tire is designed only for temporary use. Check the inflation pressure of the temporary spare tire periodically to keep the tire ready for use. The correct pressure is 60 psi (4.2 kg/cm2, 420 kPa). When using the temporary spare tire, note the fol- lowing:

IMPREZA(NA) A1830BE-A (ENGLISH)

In case of emergency

D Do not exceed 50 mph (80 km/h). D Do not put a tire chain on the temporary spare tire. Because of the smaller tire size, a tire chain will not fit properly. D Do not use two or more temporary spare tires at the same time. D Do not drive over obstacles. This tire has a smaller diameter, so road clearance is reduced.

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.

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

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.

Maintenance schedule

Maintenance precautions

The scheduled maintenance items required to be serviced at regular intervals are shown in the “War- ranty and Maintenance Booklet”. 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.

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.

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.

In choosing an oil, you want the proper quality and viscosity, as well as one that will add to fuel econo- my. 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.

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. Never mix different kinds of coolant.

HGB001CB

1) “FULL” level mark 2) “LOW” level mark

1. Check the coolant level on the outside of the res- ervoir while the engine is cool. 2. 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.

Air cleaner 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.

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.

J Replacing the air cleaner element B Non-turbo models Replace the air cleaner element according to the maintenance schedule in the “Warranty and Mainte- nance Booklet”. Under extremely dusty conditions, replace it more frequently. It is recommended that you always use genuine SUBARU parts.
