4-2. Maintenance Emission inspection and maintenance (I/M) programs

Some states have vehicle emission inspection programs which include OBD (On Board Diagnostics) checks. The OBD system moni- tors the operation of the emission control system. ■ If the malfunction indicator lamp comes on

The OBD system determines that a problem exists somewhere in the emission control system. Your vehicle may not pass the I/ M test and may need to be repaired. Contact your Toyota dealer to service the vehicle.

■ Your vehicle may not pass the I/M test in the following situa-

tions: ● When the 12-volt battery is disconnected or discharged

Readiness codes that are set during ordinary driving are erased. Also, depending on your driving habits, the readiness codes may not be completely set.

● When the fuel tank cap is loose

The malfunction indicator lamp comes on indicating a tempo- rary malfunction and your vehicle may not pass the I/M test.

■ When the malfunction indicator lamp still remains on after

several driving trips The error code in the OBD system will not be cleared unless the vehicle is driven 40 or more times.

■ If your vehicle does not pass the I/M test

Contact your Toyota dealer to prepare the vehicle for re-testing.

■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/

1000 km)

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

miles (1000 km), contact your Toyota dealer.

CAUTION

■Used engine oil

●Used engine oil contains potentially harmful contaminants which may cause skin disorders such as inflammation or skin cancer, so care should be taken to avoid prolonged and repeated contact. To remove used engine oil from your skin, wash thoroughly with soap and water.

●Dispose of used oil and filters only in a safe and acceptable manner. Do not dispose of used oil and filters in household trash, in sewers or onto the ground. Call your Toyota dealer, service station or auto parts store for information concerning recycling or disposal.

●Do not leave used engine oil within the reach of children.

■Coolant selection

Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology.

U.S.A.:

“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Minimum temperature: -31°F [-35°C]) Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Minimum temperature: -44°F [-42°C])

For more details about coolant, contact your Toyota dealer.

■If the coolant level drops within a short time of replenishing

Visually check the radiators, hoses, engine/power control unit coolant reser- voir caps, drain cock and water pump. If you cannot find a leak, have your Toyota dealer test the cap and check for leaks in the cooling systems.

CAUTION

■When the hybrid system is hot

Do not remove the engine/power control unit coolant reservoir caps. The cooling system may be under pressure and may spray hot coolant if the cap is removed, causing serious injuries, such as burns.

NOTICE

■When adding coolant

Coolant is neither plain water nor straight antifreeze. The correct mixture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be sure to read the antifreeze or coolant label.

■If you spill coolant

Be sure to wash it off with water to prevent it from damaging parts or paint.

To equalize tire wear and extend tire life, Toyota recom- mends that tire rotation is carried out at the same inter- val as tire inspection.

■ Tire rotation

Front

■ Tire pressure warning system (if equipped)

Your vehicle 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. 416)

365

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 ID codes must be registered in the tire pressure warn- ing computer and the tire pressure warning system must be initial- ized. Have tire pressure warning valve and transmitter ID codes registered by your Toyota dealer. (→P. 367) ■ The tire pressure warning system must be initialized in the fol-

lowing circumstances: ● When the tire inflation pressure is changed such as when

changing travelling speed or load weight

● When changing the tire size

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 a safe place and turn the “POWER” switch off. Initialization cannot be performed while the vehicle is moving. Adjust the tire inflation pressure to the specified cold tire infla- tion pressure level. (→P. 480) 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 “POWER” switch to ON mode.

Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks slowly 3 times.

STEP 5

Wait for a few minutes with the “POWER” switch in IGNITION ON mode and then turn the “POWER” switch off.

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. Have the ID code registered by your Toyota dealer.

367

4-3. Do-it-yourself maintenance

■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, and 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 blinks for 1
minute and stays on to indicate a system malfunction.

■Tire life

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

■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.

■Maximum load of tire

Check that the maximum load 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. 486)

368

4-3. Do-it-yourself maintenance

■Tire types

●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.

●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.

●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 restrictions. Snow tires should be installed on all wheels. (→P. 225) ■Initializing the tire pressure warning system

Initialize the system with the tire inflation pressure adjusted to the speci- fied level.

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

The effectiveness of the tires as snow tires is lost.

■If you press 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.

369

4-3. Do-it-yourself maintenance

■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 blink 3 times.

●After driving for a certain period of time since the initialization has been completed, the warning light comes on after blinking for 1
minute.

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 handling characteristics, which may lead to an accident resulting in death or serious injury. ●Do not mix tires of different makes, models or tread patterns.

Also, do not mix tires of remarkably different treadwear.

●Do not use tire sizes other than those recommended by Toyota. ●Do not mix differently constructed tires (radial, bias-belted or bias-ply

tires).

●Do not mix summer, all season and snow tires. ●Do not use tires that have been used on another vehicle.

Do not use tires if you do not know how they were used previously.

■When initializing the tire pressure warning system

Do not operate the tire pressure warning reset switch without first adjust- ing the tire inflation pressure to the specified level. Otherwise, the tire pressure 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 nor- mal.

371

4-3. Do-it-yourself maintenance

NOTICE

■Repairing or replacing tires, wheels, tire pressure warning valves,

transmitters and tire valve caps ●When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters, contact your Toyota dealer as the tire pres- sure warning valves and transmitters may be damaged if not handled correctly.

●When replacing tire valve caps, do not use tire valve caps other than

those specified. The cap may become stuck.

■To avoid damage to the tire pressure warning valves and transmit-

ters When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact your Toyota dealer or other qualified service shop as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when replacing the tire. (→P. 366)

■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 pressure of each tire becomes low while driving Do not continue driving, or your tires and/or wheels may be ruined.

Remove the tire valve cap. Press the tip of the tire pressure gauge onto the tire valve. Read the pressure using the gauge gradations. If the tire inflation pressure is not at the recommended level, adjust the pressure. If you add too much air, press the center of the valve to deflate. After completing the tire inflation pressure measurement and adjustment, apply soapy water to the valve and check for leakage. Put the tire valve cap back on.

■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.

374

4-3. Do-it-yourself maintenance

■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 inflating, 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 or has not been driven for more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure reading.

●Always use a tire pressure gauge.

The appearance of the tire can be misleading. In addition, tire infla- tion pressure that is even just a few pounds off can affect ride quality and handling.

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

375

4-3. Do-it-yourself maintenance

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 put the tire valve caps back on. 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 are lost, replace them as soon as possible.

376

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 a 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 inset*. Replacement wheels are available at your Toyota dealer. *: Conventionally referred to as “offset”. Toyota does not recommend using the following: ● Wheels of different sizes or types ● Used wheels ● Bent wheels that have been straightened

■ Aluminum wheel precautions (if equipped)

● 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 use a plastic or rubber hammer when balancing your wheels.

377

4-3. Do-it-yourself maintenance

■When replacing wheels (vehicles with a tire pressure warning sys-

tem) The wheels of your vehicle are equipped with tire pressure warning valves and transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure warning valves and trans- mitters must be installed. (→P. 366)

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 a 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 death or seri- ous injury.

■When installing the wheel nuts

facing

tapered ends

●Be sure to install the wheel nuts with the inward. Installing the nuts with the tapered ends facing outward can cause the wheel to break and eventually cause the wheel to come off while driving, which could lead to an accident resulting in death or serious injury.

Tapered portion

●Never use oil or grease on the wheel bolts or wheel nuts.

Oil and grease may cause the wheel nuts to be excessively tightened, leading to bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts to loosen and the wheel may fall off, causing an accident and resulting in death or serious injury. Remove any oil or grease from the wheel bolts or wheel nuts.
