CAUTION

The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become electrically energized. To avoid death or serious injury observe the following precautions. ■When working on the engine compartment

●Keep hands, clothing, and tools away from the moving fan and engine

drive belt.

●Be careful not to touch the engine, radiator, exhaust manifold, etc. right

after driving as they may be hot. Oil and other fluids may also be hot.

●Do not leave anything that may burn easily, such as paper or rags, in the

engine compartment.

●Do not smoke, cause sparks or expose an open flame to fuel or the bat-

tery. Fuel and battery fumes are flammable.

●Be extremely cautious when working on the battery. It contains poisonous

and corrosive sulfuric acid.

●Take care because brake fluid can harm your hands or eyes and damage

painted surfaces. If fluid gets on your hands or in your eyes, flush the affected area with clean water immediately. If you still experience discomfort, see a doctor.

●Do not touch the engine compartment when the electric cooling fan is

operating. Vehicles without smart key system: The electric cooling fan may keep rotating for about 3 minutes even after the engine switch is turned to the “LOCK” position. With the engine switch in the “ON” position, the electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is high. Be sure the engine switch is in the “LOCK” position when working near the electric cooling fan or radiator grille. Vehicles with smart key system: The electric cooling fan may keep rotating for about 3 minutes even after the “ENGINE START STOP” switch is OFF. With the “ENGINE START STOP” switch in IGNITION ON mode, the elec- tric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is high. Be sure the “ENGINE START STOP” switch is OFF when working near the electric cooling fan or radia- tor grille.

■ How to read oil container labels

Some oil containers are labeled with ILSAC certification marks that help you to select the proper oil.

Standardization

Oil identification mark The ILSAC (International Lubri- cant and Approval Committee) Certifica- tion Mark is added to some oil containers to help you select the oil you should use.

■Engine oil consumption

●The amount of engine oil consumed depends on the oil viscosity, the

quality of the oil and the way the vehicle is driven.

●More oil is consumed under driving conditions such as high speeds and

frequent acceleration and deceleration.

●A new engine consumes more oil. ●When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accu- rately.

●Oil consumption: Max. 1.1 qt./600 miles, 0.9 Imp. qt./600 miles (1.0 L per

1000 km)

●If your vehicle consume more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600

miles (1000 km), contact your Toyota dealer.

■ The tire pressure warning system

Your Toyota is equipped with a tire pressure warning system that uses tire pressure warning valves and transmitters to detect low tire inflation pressure before serious problems arise. (→P. 513, 521) Vehicles with compact spare tire: The compact spare tire is not equipped with the tire pressure warning valve and transmitters.

454

4-3. Do-it-yourself maintenance

Installing tire pressure warning valves and transmitters

When replacing tires or wheels, tire pressure warning valves and transmitters must also be installed. When new tire pressure warning valves and transmitters are installed, new tire pressure warning valve and transmitter ID codes must be registered in the tire pressure warning computer and the tire pressure warning system must be initialized. Have tire pressure warning valve and transmitter ID codes registered by your Toyota dealer. (→P. 457)

Initializing the tire pressure warning system

■ The tire pressure warning system must be initialized when the tire inflation pressure is changed (such as when changing traveling speed or towing a trailer.)

When the tire pressure warning system is initialized, the current tire inflation pressure is set as the benchmark pressure. ■ How to initialize the tire pressure warning system STEP 1

Park the vehicle in safe place and turn the “ENGINE START STOP” switch or the engine switch OFF. While the vehicle is moving, initialization is not performed. Adjust the tire inflation pressure to the specified cold tire infla- tion pressure level. (→P. 562) Make sure to adjust the tire pressure to the specified cold tire inflation pressure level. The tire pressure warning system will operate based on this pressure level. Turn the “ENGINE START STOP” switch to IGNITION ON mode (vehicles with smart key system) or the engine switch to the “ON” position (vehicles without smart key system).

4-3. Do-it-yourself maintenance

Registering ID codes

The tire pressure warning valve and transmitter is equipped with a unique ID code. When replacing a tire pressure warning valve and transmitter, it is necessary to register the ID code of tire pressure warning valve and transmitter. Have the ID code registered by your Toyota dealer.

■When to replace your vehicle's tires

Tires should be replaced if: ●You have tire damage such as cuts, splits, cracks deep enough to

expose the fabric, or bulges indicating internal damage

●A tire goes flat repeatedly or cannot be properly repaired due to the

size or location of a cut or other damage

If you are not sure, consult with your Toyota dealer.

■Replacing tires and wheels

If the ID code of the tire pressure warning valve and transmitter is not registered, the tire pressure warning system will not work properly. After driving for about 20 minutes, the tire pressure warning light comes on after blinking for 1 minute to indicate a system malfunction.

■Tire life

Any tire over 6 years old must be checked by a qualified technician even if they have seldom or never been used or damage is not obvious.

■If the tread wears down below 0.16 in. (4 mm) on snow tires

The effectiveness of snow tires is lost.

■When the tire pressure warning valves and transmitter are removed

from the wheel on occasions such as when replacing tires The tire inflation pressure data updated before servicing is retained.

457

4-3. Do-it-yourself maintenance

■Maximum load of tire

Check that the number given by dividing the maximum load by 1.10 of the replacement tire is greater than 1/2 of the Gross Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is greater.

For the GAWR, see the Certification Label. For the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire. (→P. 570)

■Tire types

1 Summer tires

Summer tires are high-speed performance tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction performance as snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For driving on snow-covered roads or icy roads, the use of snow tires is recommended. When installing snow tires, be sure to replace all four tires.

2 All season tires

All season tires are designed to provide better traction in snow and to be adequate for driving in most winter conditions, as well as for use year round. All season tires, however, do not have adequate traction performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in acceleration and handling performance compared with summer tires in highway driving.

3 Snow tires

For driving on snow-covered roads or icy roads, we recommend using snow tires. If you need snow tires, select tires of the same size, con- struction and load capacity as the originally installed tires. Since your vehicle has radial tires as original equipment, make sure your snow tires also have radial construction. Do not install studded tires without first checking local regulations for possible restriction. Snow tires should be installed on all wheels. (→P. 238)

458

4-3. Do-it-yourself maintenance

■Initializing the tire pressure warning system

Initialize the tire pressure warning system with the tire inflation pressure adjusted to the specified level.

■If you push the tire pressure warning reset switch accidentally

If initialization is performed, adjust the tire inflation pressure to the speci- fied level and initialize the tire pressure warning system again.

■When the initialization of the tire pressure warning system has

failed Initialization can be completed in a few minutes. However, in the follow- ing cases, the settings have not been recorded and the system will not operate properly. If repeated attempts to record tire inflation pressure settings are unsuccessful, have the vehicle inspected by your Toyota dealer. ●When operating the tire pressure warning reset switch, the tire pres-

sure warning light does not flash 3 times.

●After carrying out the initialization procedure, the tire pressure warn- ing light blinks for 1 minute then stays on after driving for about 20
minutes.

■Routine tire inflation pressure checks

The tire pressure warning system does not replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily vehicle checks.

CAUTION

■When inspecting or replacing tires

Observe the following precautions to prevent accidents. Failure to do so may cause damage to parts of the drive train, as well as dangerous han- dling characteristics, which may lead to an accident resulting in death or serious injury. ●Do not mix tires of different makes, models, tread patterns or tread-

wear.

●Do not use tire sizes other than those recommended by Toyota. ●Do not mix radial, bias-belted, or bias-ply tires. ●Do not mix summer, all season and winter tires. ●Do not tow the vehicle with the spare tire installed.

■When initializing the tire pressure warning system

Do not push the tire pressure warning reset switch without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pres- sure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal.

461

4-3. Do-it-yourself maintenance

NOTICE

■Repairing or replacing tires, wheels and tire pressure warning

valves and transmitters When removing or fitting the wheels, tires or the tire pressure warning valve and transmitter, contact your Toyota dealer as the tire pressure warning valve and transmitter may be damaged if not handled correctly. ■To avoid damaging the tire pressure warning valves and transmit-

ters Do not use liquid sealants on flat tires.

■Do not use puncture sealant sprays to repair flats

Puncture sealant sprays may damage tire pressure warning valves and transmitters.

■Driving on rough roads

Take particular care when driving on roads with loose surfaces or pot- holes. These conditions may cause losses in tire inflation pressure, reducing the cushioning ability of the tires. In addition, driving on rough roads may cause damage to the tires themselves, as well as the vehicle's wheels and body.

■If tire inflation pressures become low while driving

Do not continue driving, or your tires and/or wheels may be ruined.

Press the tip of the tire pressure gauge onto the tire valve. Read the pressure using the graduations of the gauge. If the tire inflation pressure is not within the recommended levels, adjust the pressure. If you add too much air, press the center of the valve to lower. After completing the tire inflation pressure measurement and adjustment, apply soapy water to the valve and check for leakage. Reinstall the tire valve cap.

■Tire inflation pressure check interval

You should check tire inflation pressure every two weeks, or at least once a month. Do not forget to check the spare.

■Effects of incorrect tire inflation pressure

Driving with incorrect tire inflation pressure may result in the following: ●Reduced fuel efficiency ●Reduced driving comfort and tire life ●Reduced safety ●Damage to the drive train If a tire needs frequent refilling, have it checked by your Toyota dealer.

■Instructions for checking tire inflation pressure

When checking tire inflation pressure, observe the following: ●Check only when the tires are cold.

If your vehicle has been parked for at least 3 hours and has not been driven for more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure reading.

465

4-3. Do-it-yourself maintenance

●Always use a tire pressure gauge.

The appearance of the tire can be misleading. In addition, tire infla- tion pressures that are even just a few pounds off can degrade ride and handling.

●Do not bleed or reduce tire inflation pressure after driving. It is normal

for the tire inflation pressure to be higher after driving.

●Never exceed the vehicle capacity weight.

Passengers and luggage weight should be placed so that the vehicle is balanced.

CAUTION

■Proper inflation is critical to save tire performance

Keep your tires properly inflated. Otherwise, the following conditions may occur and result in an accident causing death or serious injury. ●Excessive wear ●Uneven wear ●Poor handling ●Possibility of blowouts resulting from overheated tires ●Poor sealing of the tire bead ●Wheel deformation and/or tire separation ●A greater possibility of tire damage from road hazards

NOTICE

■When inspecting and adjusting tire inflation pressure

Be sure to reinstall the tire valve caps. Without the valve caps, dirt or moisture could get into the valve and cause air leakage, which could result in an accident. If the caps have been lost, replace them as soon as possible.

466

4-3. Do-it-yourself maintenance Wheels

If a wheel is bent, cracked or heavily corroded, it should be replaced. Otherwise, the tire may separate from the wheel or cause loss of handling control. ■ Wheel selection

When replacing wheels, care should be taken to ensure that they are equivalent to those removed in load capacity, diameter, rim width, and offset. Replacement wheels are available at your Toyota dealer. Toyota does not recommend using: ● Wheels of different sizes or types ● Used wheels ● Bent wheels that have been straightened

■ Aluminum wheel precautions

● Use only Toyota wheel nuts and wrenches designed for use

with your aluminum wheels.

● When rotating, repairing or changing your tires, check that the

wheel nuts are still tight after driving 1000 miles (1600 km).

● Be careful not to damage the aluminum wheels when using

tire chains.

● Use only Toyota genuine balance weights or equivalent and a

plastic or rubber hammer when balancing your wheels.

■When replacing wheels

The wheels of your Toyota are equipped with tire pressure warning valves and transmitters that allow the tire pressure warning system to provide advanced warning in the event of a loss in tire inflation pressure. Whenever wheels are replaced, the tire pressure warning valves and transmitters must be installed. (→P. 455)

CAUTION

■When replacing wheels

●Do not use wheels that are a different size from those recommended in

the Owner’s Manual, as this may result in loss of handling control.

●Never use an inner tube in a leaking wheel which is designed for a tubeless tire. Doing so may result in an accident, causing serious injury or death.

NOTICE

■Replacing tire pressure warning valves and transmitters

●Because tire repair or replacement may affect the tire pressure warning valves and transmitters, make sure to have tires serviced by your Toyota dealer or other qualified service shop. In addition, make sure to purchase your tire pressure warning valves and transmitters at your Toyota dealer.

●Ensure that only genuine Toyota wheels are used on your vehicle.

Tire pressure warning valves and transmitters may not work properly with non-genuine wheels.
