Before putting on wheels, remove any cor- rosion on the mounting surfaces with a wire brush or such. Installation of wheels without good metal−to−metal contact at the mounting surface can cause wheel nuts to loosen and eventually cause a wheel to come off while driving. Therefore after the first 1600 km (1000 miles), check to see that the wheel nuts are tight.

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 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.

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

antifreeze

CAUTION

When cleaning under floor or chassis, be careful not to injure your hands.

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, etc.; 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 Toyota dealer will be happy to assist in supplying and installing the shields if they are recommended 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.

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.

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.

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.

For scheduled maintenance information, please refer to the separate ”Owner’s Manual Supplement/Maintenance Schedule”.

Maintenance requirements Your Toyota vehicle has been designed to for fewer maintenance requirements with longer service intervals to save both your time and money. However, each regular maintenance, as well as day−to−day care, is more important than ever before to en- sure smooth, trouble−free, safe, and eco- nomical drivings. It is the owner’s responsibility to make sure the specified maintenance, including general maintenance service, is performed. Note that both the new vehicle and emis- sion control system warranties specify that proper maintenance and care must be per- formed. See Owner’s Guide, Owner’s Manual Supplement or Warranty Booklet for complete warranty information. General maintenance General maintenance items are those day− to−day care practices that are important to your vehicle for proper operation. It is the owner’s responsibility to insure that the general maintenance items are performed regularly. These checks or inspections can be done either by yourself or a qualified technician, or if you prefer, your Toyota dealer will be pleased to do them at a nominal cost.

Scheduled maintenance The scheduled maintenance items listed in the ”Owner’s Manual Supplement/Mainte- nance Schedule” are those required to be serviced at regular intervals. For details of your maintenance schedule, read ”Owner’s Manual Supplement/Maintenance Schedule”. It is recommended that any replacement parts used for maintenance or for the repair of the emission control system be Toyota supplied. The owner may elect to use non−Toyota supplied parts replacement pur- poses without invalidating the emission control system warranty. However, use of replacement parts which are not of equivalent quality may impair the effec- tiveness of the emission control sys- tems. You may also elect to have mainte- nance, replacement, or repair of the emission control devices and system performed by any automotive repair es- tablishment or individual without invali- dating this warranty.

OUTSIDE THE VEHICLE Items listed below should be performed from time, unless otherwise specified. Tire pressure Check the pressure with a gauge every two weeks, or at least once a month. See Chapter 7−2 for additional information.

If you are a skilled do−it−yourself mechan- ic, the Toyota service manuals are recom- mended. Please be aware that do−it−your- self maintenance can affect your warranty coverage. See Owner’s Guide, Owner’s Manual Supplement or Warranty Booklet for the details.

Where to go for service? Toyota technicians are well−trained spe- cialists and are kept up to date with the latest service information through technical bulletins, service tips, and in−dealership training programs. They learn to work on Toyotas before they work on your vehicle, rather than while they are working on it. You can be confident that your Toyota dealer’s service department performs the best job to meet the maintenance require- ments on your vehicle—reliably and eco- nomically. Your copy of the repair order is proof that all required maintenance has been per- formed for warranty coverage. And if any problems should arise with your vehicle while under warranty, your Toyota dealer will promptly take care of it. Again, be sure to keep a copy of the repair order for any service performed on your Toyota. What about do−it−yourself maintenance? Many of the maintenance items are easy to do yourself if you have a little mechani- cal ability and a few basic automotive tools. Simple instructions for how to per- form them are presented in Part 7.

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; pedal almost touches floor; vehicle pulls to one side when braking

D Engine coolant temperature continually

higher than normal

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:

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 skin, wash thoroughly with soap and water.

D Do not

leave used oil within the

reach of children.

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 SH, ”Energy−Conserving II” or SJ, ”Energy−Conserving” multigrade engine oil or ILSAC multigrade engine oil. Recommended viscosity (SAE):

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. 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. Use only ethylene−glycol 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, engine coolant filler cap, radiator cap and drain cock and water pump. If you can find no leak, have your Toyota dealer test the cap pressure and check for leaks in the cooling system.

CAUTION

To prevent burning yourself, do not remove the radiator cap when the en- gine is hot.

Coolant type selection Your coolant must contain ethylene−glycol antifreeze. In addition to preventing freez- ing and subsequent damage to the engine, this will also prevent corrosion. Further supplemental inhibitors or additives are neither needed nor recommended. Read the antifreeze container for informa- tion on the manufacturer’s directions for how much to mix with water. The total capacity of the cooling system is given in Part 8. We recommend 50% solution be used for your Toyota, or a sufficient quantity to provide protection to about −35_C (−31_F).

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.

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.

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.

name. SIENNA (U)

D Take special care when adding air to the compact spare tire. The smaller tire size can gain pressure very quick- ly. Add compressed air in small quanti- ties and check the pressure often until it reaches the specified pressure.

D Do not bleed or reduce tire pressure after driving. It is normal for the tire pressure to be higher after driving.

D Never exceed

the vehicle capacity weight. The passenger and luggage weight should be located so that the vehicle is balanced.

D Be sure to reinstall the tire inflation valve caps. Without the valve caps, dirt or moisture could get into the valve core and cause air leakage. If the caps have been lost, have new ones put on as soon as possible.

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 Toyota 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- leading. Besides, that are even just a few pounds off can degrade handling and ride.

Toyota recommends all four tires, or at least both of the front or rear tires be replaced at a time as a set. See ”If you have a flat tire” in Part 4 for tire change procedure. When a is replaced, should always be balanced. An unbalanced wheel may affect vehicle handling and tire life. Wheels can get out of balance with regular use and should therefore be balanced occasionally. When replacing a tubeless tire, the air valve should also be replaced with a new one.

Checking and replacing tires

Tread wear indicator

CHECKING YOUR TIRES Check the tires tread for the tread wear indicators. If the indicators show, re- place the tires. The tires on your Toyota have built−in tread wear indicators to help you know when the tires need replacement. When the tread depth wears to 1.6 mm (0.06
in.) or less, the indicators will appear. If you can see the indicators in two or more adjacent grooves, the tire should be re- placed. The lower the tread, the higher the risk of skidding. The effectiveness of snow tires is lost if the tread wears down below 4 mm (0.16 in.).

230

Check the tires regularly for damage such as cuts, splits and cracks. If any damage is found, consult with a techni- cian and have the tire repaired or re- placed. Even if the damage does not appear seri- ous, a qualified technician should examine the damage. Objects which have pene- trated the tire may have caused internal damage. Any tires which are over six years old must be checked by a qualified techni- cian even if damage is not obvious. Tires deteriorate with age even have never or seldom been used. This applies also to the spare tire and tires stored for future use. REPLACING YOUR TIRES When replacing a tire, use only the same size and construction as original- ly installed and with the same or great- er load capacity. Using any other size or type of tire may seriously affect handling, ride, speedome- ter/odometer calibration, ground clearance, and clearance between the body and tires or snow chains.

To equalize the wear and help extend tire life, Toyota recommends that you rotate your tires approximately every 12000 km (7500 miles). However, the most appropriate timing for tire rotation may vary according to your driving hab- its and road surface conditions. See ”If you have a flat tire” in Part 4 for tire change procedure. When for uneven wear and damage. Abnormal wear is usu- ally caused by incorrect tire pressure, im- proper wheel alignment, out−of−balance wheels, or severe braking.

Installing snow tires and chains WHEN TO USE SNOW TIRES OR CHAINS Snow tires or chains are recommended when driving on snow or ice. On wet or dry roads, conventional tires provide better traction than snow tires. SNOW TIRE SELECTION If you need snow tires, select the same size, construction and load capacity as the original tires on your Toyota. Do not use tires other than those men- tioned above. Do not install studded tires without first checking local regulations for possible restrictions. SNOW TIRE INSTALLATION Snow tires should be installed on all wheels. Installing snow tires on the front wheels only can lead to an excessive difference in road grip capability between the front and rear tires which could cause loss of vehicle control. When storing removed tires, you should store them in a cool dry place. Mark the direction of rotation and be sure to install them in the same direction when replac- ing.

Replacing wheels WHEN TO REPLACE YOUR WHEELS If you have wheel damage such as bending, cracks or heavy corrosion, the wheel should be replaced. If you fail to replace damaged wheels, the tire may slip off the wheel or they may cause loss of handling control. WHEEL SELECTION When replacing wheels, care should be taken to ensure that the wheels are re- placed by ones with the same load ca- pacity, diameter, rim width, and offset. This must be observed on compact spare tires, too. Correct replacement wheels are available at your Toyota dealer. A wheel of a different size or type may adversely affect handling, wheel and bear- ing life, brake cooling, speedometer/odom- eter calibration, stopping ability, headlight aim, bumper height, vehicle ground clear- ance, and tire or snow chain clearance to the body and chassis.

If wheel covers are used, they will be scratched by the chain band,so remove the covers before putting on the chains.

limit, whichever

D Drive carefully avoiding bumps, holes, and sharp turns, which may cause the vehicle to bounce.

D Avoid sharp turns or locked−wheel braking, as use of chains may ad- versely affect vehicle handling.

NOTICE

Do not attempt to use a tire chain on the compact spare tire, as it may re- sult in damage to the vehicle as well as the tire.

CAUTION

D Do not drive with the snow tires

incorrectly inflated.

D Never drive over 120 km/h (75 mph)

with any type of snow tires.

TIRE CHAIN SELECTION Use the tire chains of correct size and type. Use SAE Class ”S” type radial tire chains except radial cable chains or V−bar type chains. Regulations regarding the use of tire chains vary according to location or type of road, so always check them before installing chains. CHAIN INSTALLATION Install the chains on the front tires as tightly as possible. Do not use tire tires. Retighten chains on chains after km (1/4—1/2 mile). When installing chains on your tires, care- fully follow the instructions of the chain manufacturer.
