Protecting your Toyota from corrosion Toyota, through its diligent research, de- sign and use of the most advanced technology available, has done its part to help prevent corrosion and has provided you with vehicle construction. Now, it is up to you. Proper care of your Toyota can help ensure long− term corrosion prevention. The most common causes of corrosion to your vehicle are: D The accumulation of road salt, dirt and moisture in hard−to−reach areas under the vehicle.

finest
D Chipping of paint, or undercoating caused by minor accidents or by stones and gravel.
Care is especially important if you live in particular areas or operate your ve- hicle under certain environmental condi- tions: D Road salt or dust control chemicals will accelerate corrosion, as will the pres- ence of salt in the air near the sea− coast or in areas of industrial pollution. D High humidity accelerates corrosion es- pecially when temperatures range just above the freezing point.
D Wetness or dampness to certain parts of your vehicle for an extended period of time, may cause corrosion even though other parts of the vehicle may be dry.
those components of
D High temperatures will cause corrosion to the vehicle which are prevented from quick−drying due to lack of proper ventilation.
The above signifies the necessity to keep your vehicle, particularly the underside, as clean as possible and to repair any dam- age to paint or protective coatings as soon as possible. To help prevent corrosion on your Toyota, follow these guidelines: Wash your vehicle frequently. It is, of course, necessary to keep your vehicle clean by regular washing, but to prevent corrosion, the following points should be observed: D If you drive on salted roads
the winter or if you live near the ocean, you should hose off the undercarriage at least once a month to minimize cor- rosion.

145
D High pressure water or steam is effec- tive for cleaning the vehicle’s underside and wheel housings. Pay particular attention to these areas as it is difficult to see all the mud and dirt. It will do more harm than good to simply wet the mud and debris without removing them. The lower edge of doors, rocker panels and frame members have drain holes which should not be allowed to clog with dirt as these areas can cause corrosion.

D Wash the underside of the vehicle thor-
oughly when winter is over.
See “Washing and waxing your Toyota” for more tips. Check the condition of your vehicle’s paint and trim. If you find any chips or scratches in the paint, touch them up im- mediately to prevent corrosion from start- ing. If the chips or scratches have gone through the bare metal, have a qualified body shop make the repair.
146
Check the interior of your vehicle. Wa- ter and dirt can accumulate under the floor mats and could cause corrosion. Oc- casionally check under the mats to make sure the area is dry. Be particularly care- ful when transporting chemicals, cleans- ers, fertilizers, salt, e tc.; these should be transported in proper containers. If a spill or leak should occur, immediately clean and dry the area. Use mud shields on your wheels. If you drive on salted or gravel roads, mud shields help protect your vehicle. Full−size shields, which come as near to the ground as possible, are the best. We recommend that the fittings and the area where the shields are installed be treated to resist corrosion. Your authorized Toyota CNG dealer will be happy to assist in supplying and installing the shields if they are rec- ommended for your area. Keep your vehicle in a well ventilated garage or a roofed place. Do not park your vehicle in a damp, poorly venti- lated garage. If you wash your vehicle in the garage, or if you drive it in covered with water or snow, your garage may be so damp it will cause corrosion. Even if your garage is heated, a wet vehicle can corrode if the ventilation is poor.
Washing and waxing your Toyota Washing your Toyota Keep your vehicle clean by regular washing. The following cases may cause weakness to the paint or corrosion to the body and parts. Wash your vehicle as soon as pos- sible. D When driving in a coastal area D When driving on a road sprinkled with

Automatic car wash Your vehicle may be washed in an auto- matic car wash, but remember that the paint can be scratched by some type of brushes, unfiltered washing water, or the washing process itself. Scratching reduces paint durability and gloss, especially on darker colors. The manager of the car wash should be able to advise you wheth- er the process is safe for the paint on your vehicle. Waxing your Toyota Polishing and waxing is recommended to maintain the original beauty of your Toyota’s finish. Once a month or if the vehicle does not repel water well, apply wax.
1. Always wash and dry the vehicle be- fore you begin waxing, even if you are using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has become extremely weath- ered, use a car−cleaning polish, fol- lowed by a separate wax. Carefully fol- low the manufacturer’s instructions and precautions. Be sure to polish and wax the chrome trim as well as the paint. the vehicle again when water does not bead but remains on the sur- face in large patches.

CAUTION
Do not wash the vehicle floor with water, or allow water to get onto the floor when cleaning the vehicle interi- or or exterior. Water may get into audio components or other electrical components above or under the floor carpet (or mat) and cause a malfunc- tion; and it may cause body corro- sion.
Vinyl interior The vinyl upholstery may be easily cleaned with a mild soap or detergent and water. First vacuum over the upholstery to re- move loose dirt. Then, using a sponge or soft cloth, apply the soap solution to the vinyl. After allowing it to soak in for a few minutes to loosen the dirt, remove the dirt and wipe off the soap with a clean damp cloth. If all the dirt do not come off, re- peat the procedure. Commercial foaming− type vinyl cleaners are also available which work well. Follow the manufacturer’s instructions.

Power steering fluid level Check the level through the reservoir. The level should be in the “HOT” or “COLD” range depending on the fluid temperature. See Chapter 7−2 for additional information. Exhaust system If you notice any change in the sound of the exhaust or smell exhaust fumes, have the cause located and corrected immedi- ately. in Part 2.)
(See engine exhaust cautions
IN THE ENGINE COMPARTMENT Items listed below should be checked from time to time, e.g. each time when refueling. Washer fluid Make sure there is sufficient fluid in the tank. See Chapter 7−3 for additional in- formation. Engine coolant level Make sure the coolant level is between the “FULL” and “LOW” lines on the see− through reservoir when the engine is cold. See Chapter 7−2 for additional information. Battery electrolyte level Make sure the electrolyte level of all bat- tery cells is between upper and lower lev- el lines on the case. Add only distilled water when replenishing. See Chapter 7−3
for additional information. Brake fluid level Make sure the brake fluid level is correct. See Chapter 7−2 for additional information. Engine oil level Check the level on the dipstick with the engine turned off and the vehicle parked on a level spot. See Chapter 7−2 for addi- tional information.154
tip−offs
for changes
Does your vehicle need repairing? Be on the alert in perfor- mance, sounds, and visual that indicate service is needed. Some impor- tant clues are as follows: D Engine missing, stumbling, or pinging D Appreciable loss of power D Strange engine noises D A leak under the vehicle (however, wa- ter dripping from the air conditioning after use is normal.)
D Change
in exhaust sound (This may indicate a dangerous carbon monoxide leak. Drive with the windows open and have the exhaust system checked im- mediately.)
D Flat−looking tire; excessive tire squeal
when cornering; uneven tire wear
D Vehicle pulls to one side when driving
straight on a level road
D Strange noises related to suspension
movement
D Loss of brake effectiveness; spongy feeling brake; pedal almost touches floor; vehicle pulls to one side when braking
D Engine coolant temperature continually
higher than normal
If you notice any of these clues, take your vehicle to your authorized Toyota CNG dealer as soon as possible. It probably needs adjustment or repair.
CAUTION
Do not continue driving with the ve- hicle unchecked. It could result in se- rious vehicle damage and possibly personal injury.

Do−it−yourself service precautions If you perform maintenance by yourself, be sure to follow the correct procedure given in this part. You should be aware that improper or in- complete servicing may result in operating problems. Performing do−it−yourself maintenance during the warranty period may affect your warranty coverage. Read the separate Toyota Warranty statement for details and suggestions. This part gives instructions only for those items that are relatively easy for an owner to perform. As explained in Part 6, there are still a number of items that must be done by a qualified technician with special tools. For information on tools and parts for do− it−yourself maintenance, see “Parts and tools”. Utmost care should be taken when work- ing on your vehicle to prevent accidental injury. Here are a few precautions that you should be especially careful to ob- serve:
160
CAUTION
D Never work on the fuel system by yourself. Any work on this system must be performed by your autho- rized Toyota CNG dealer. If an un- qualified person works on it incor- rectly causing fuel leaks etc., a fire hazard or explosion may occur, which is very dangerous.
D When the engine is running, keep tools away hands, clothing, and from the moving fan and engine drive rings, watches, and ties is advisable.)
(Removing
belts.
D Right after driving,
the engine compartment—the engine, radiator, exhaust manifold and spark plug boots, etc.—will be hot. So be care- ful not to touch them. Oil, fluids and spark plugs may also be hot.
D If the engine is hot, do not remove the radiator cap or loosen the drain plugs to prevent burning yourself.
D Do not smoke, cause sparks or al- low open flames around fuel or the battery. Their fumes are flammable.
D Be extremely cautious when work- ing on the battery. It contains poi- sonous and corrosive sulfuric acid. D Do not get under your vehicle with just the body jack supporting it. Al- ways use automotive jack stands or other solid supports.
D Be sure that the ignition is off if you work near the electric cooling fans or radiator grille. With the ignition on, the electric cooling fans will automatically start to run if the engine coolant temperature is high and/or the air conditioning is on.
D Use eye protection whenever you work on or under your vehicle where you may be exposed to flying or falling material, fluid spray, etc. D Used engine oil contains potentially harmful contaminants which may cause skin disorders such as in- flammation or skin cancer, so care should be taken to avoid prolonged and repeated contact with it. To re- move used engine oil from your thoroughly with soap skin, wash and water.
z Use only spark plugs of the speci- fied type. Using other types will cause engine damage, loss of per- formance or radio noise.
z Do not reuse platinum−tipped spark
plugs by cleaning or regapping.
z Do not overfill automatic transmis- transmission
fluid, or
the
sion could be damaged.
z Do not drive with the air cleaner filter removed, or excessive engine wear could result. Also backfiring could cause a fire in the engine compartment.
z Be careful not to scratch the glass
surface with the wiper frame.
z When closing
the engine hood, check to see that you have not for- gotten any tools, rags, etc.
D Do not
leave used oil within the
reach of children.
D Dispose of used oil and filter only in a safe and acceptable manner. Do not dispose of used oil and fil- ter in household trash, in sewers or onto the ground. Call your autho- rized Toyota CNG dealer or a ser- vice station information con- cerning recycling or disposal.
for
NOTICE
z Remember that battery and ignition cables carry high currents or volt- ages. Be careful of accidentally causing a short circuit.
z Be careful not to touch the fuel pipe unintentionally. If an excessive force is applied on the pipe, gas may leak from its connections.
z Add only demineralized or distilled water to fill the radiator. And if you spill some of the coolant, be sure to wash off with water to prevent it from damaging the parts or paint.
z Do not allow dirt or anything else to fall through the spark plugholes.

Oil identification marks Either or both API registered marks are added to some oil containers to help you select the oil you should use. The API Service Symbol is located any- where on the outside of the container. The top portion of the label shows the oil quality by API (American Petroleum Insti- tute) designations such as SJ. The center portion of the label shows the SAE viscos- ity grade such as SAE 5W−30. “Energy− Conserving” shown in the lower portion, indicates that the oil has fuel−saving ca- pabilities. The ILSAC (International Lubricant Stan- dardization and Approval Committee) Certi- fication Mark is displayed on the front of the container.
Engine oil selection Use API grade SJ, “Energy−Conserving” or ILSAC multigrade engine oil. Recommended viscosity (SAE):
API service symbol
for good
SAE 5W−30 is the best choice for your vehicle, fuel economy, and good starting in cold weather. If you use SAE 10W−30 engine oil in extremely low temperatures, the engine may become difficult to start, so SAE 5W−30engine oil is recommended.

Checking the engine coolant level Look at the see−through coolant reser- voir when the engine is cold. The cool- ant level is satisfactory if it is between the “FULL” and “LOW” lines on the reservoir. If the level is low, add ethyl- ene−glycol type coolant for a proper corrosion protection of aluminum com- ponents. The coolant level in the reservoir will vary with engine temperature. However, if the level is on or below the “LOW” line, add coolant. Bring the level up to the “FULL” line. Always use ethylene−glycol type coolant for a proper corrosion protection of alumi- num components. See information in the next column. If the coolant level drops within a short time after replenishing, there may be a leak the radiator, hoses, radiator cap and drain cock and water pump. If you can find no leak, have your autho- rized Toyota CNG dealer the cap pressure and check for leaks in the cool- ing system.

Checking brake fluid
Checking power steering fluid
Use only newly opened brake fluid. Once opened, brake fluid absorbs moisture from the air, and excess moisture can cause a dangerous loss of braking.
CAUTION
Take care when filling the reservoir because brake fluid can harm your eyes and damage painted surfaces. If fluid gets in your eyes, flush your eyes with clean water.
NOTICE
If you spill some of the fluid, be sure to wash it off with water to prevent it from damaging the parts or paint.
reservoir. The
To check the fluid level, simply look at the see−through level should be between the “MAX” and “MIN” lines on the reservoir. It is normal for the brake fluid level to go down slightly as the brake pads wear. So be sure to keep the reservoir filled. If the reservoir needs frequent refilling, it may indicate a serious mechanical prob- lem. If the level is low, add SAE J1703 or FMVSS No.116 DOT 3 brake fluid to the brake reservoir. Remove and replace the reservoir cover by hand.

Clean all dirt from outside of the reservoir tank and look at the fluid level. If the fluid is cold, the level should be in the “COLD” range. Similarly, if it is hot, the fluid level should be in the “HOT” range. If the level is at the low side of either range, add automatic fluid DEXRONrII or III to bring the level within the range. To remove the filler cap, turn it counter- clockwise and lift up. To reinstall it, turn it clockwise. After replacing the filler cap, visually check the steering box case, vane pump and hose connections for leaks or damage.

Checking tire pressure
Keep your tire pressures at the proper level. The recommended cold tire pressures, tire size and the vehicle capacity weight are given in Part 8. They are also on the tire pressure label as shown. You should check the tire pressures every two weeks, or at least once a month. And don’t forget the spare! Incorrect tire pressure can reduce tire life and make your vehicle less safe to drive.

Low in excessive wear, poor handling, reduced fuel econo- my, and the possibility of blowouts from overheated tires. Also, low tire pressure can cause poor sealing of the tire bead. If low, there is the possibility of wheel deforma- tion and/or tire separation. High tire pressure produces a harsh ride, handling problems, excessive wear at the center of the tire tread, and a greater possibility of tire damage from road haz- ards. If a tire frequently needs refilling, have it checked by your authorized Toyota CNG dealer. The following instructions for checking tire pressure should be observed: D The pressure should be checked only when the tires are cold. If your ve- hicle has been parked for at least 3
hours and has not been driven for more than 1.5 km or 1 mile since, you will get an accurate cold tire pressure reading.D Always use a tire pressure gauge. The appearance of a tire can be mis-
