lines on the reservoir when the engine is cold.

Reservoir cap

“FULL” line

“LOW” line

If the level is on or below the

“LOW” line, add coolant up to the

“FULL” line.

■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.

For the U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% cool-

ant and 50% deionized water. (Minimum temperature: -31F

[-35C])

For Canada:

“Toyota Super Long Life Coolant” is a mixture of 55% cool-

ant and 45% deionized water. (Minimum temperature: -44F

[-42C])

For more details about engine coolant, contact your Toyota dealer.

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

Visually check the radiator, hoses, engine coolant reservoir 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 system.

352

6-3. Do-it-yourself maintenance

WARNING

■When the engine is hot

Do not remove the engine coolant reservoir cap.

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.

Radiator and condenser

Check the radiator and condenser and clear away any foreign objects.

If either of the above parts is extremely dirty or you are not sure of

their condition, have your vehicle inspected by your Toyota dealer.

WARNING

■When the engine is hot

363

6-3. Do-it-yourself maintenance

Tire pressure warning system

Your vehicle is equipped with a tire pressure warning system that uses

tire pressure warning valves and transmitters to detect low tire infla-

tion pressure before serious problems arise.

If the tire pressure drops below a predetermined level, the driver is

warned by a warning light. (P. 424)

◆ 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

warning computer and the tire pressure warning system must be

initialized. Have tire pressure warning valves and transmitter ID

codes registered by your Toyota dealer. (P. 365)

◆ Initializing the tire pressure warning system

When the tire size is changed, the tire pressure warning system

must be initialized.

When the tire pressure warning system is initialized, the current tire

inflation pressure is set as the benchmark pressure.

6

364

6-3. Do-it-yourself maintenance

■ How to initialize the tire pressure warning system

1

Park the vehicle in a safe place and turn the engine switch to the

“LOCK” position (vehicles without a smart key system) or off

(vehicles with a smart key system).

Initialization cannot be performed while the vehicle is moving.

2

Adjust the tire inflation pressure to the specified cold tire inflation

pressure level. (P. 470)

Make sure to adjust the tire pressure to the specified cold tire infla-

tion pressure level. The tire pressure warning system will operate

based on this pressure level.

3

Turn the engine switch to the “ON” position (vehicles without a

smart key system) or IGNITION ON mode (vehicles with a smart

key system).

4

Press “” or “” of the meter control switch to select

365

6-3. 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. Have the ID code

registered by your Toyota dealer.

■When to replace your vehicle’s tires

Tires should be replaced if:

●The treadwear indicators are showing on a tire.

●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 reg-

istered, the tire pressure warning system will not work properly. After driv-

ing 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 use, or damage is not obvious.

6

■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.

366

■Maximum load of tire

6-3. Do-it-yourself maintenance

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. 475)

■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 install-

ing 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 com-

pared 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. 292)

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

The effectiveness of the tires as snow tires is lost.

367

6-3. Do-it-yourself maintenance

■Situations in which the tire pressure warning system may not oper-

ate properly

●In the following cases, the tire pressure warning system may not operate

properly.

• If non-genuine Toyota wheels are used.

• A tire has been replaced with a tire that is not an OE (Original Equip-

ment) tire.

• A tire has been replaced with a tire that is not of the specified size.

• Tire chains, etc., are equipped.

• An auxiliary-supported run-flat tire is equipped.

• If a window tint that affects the radio wave signals is installed.

• If there is a lot of snow or ice on the vehicle, particularly around the

wheels or wheel housings.

• If the tire inflation pressure is extremely higher than the specified

level.

• If wheels without the tire pressure warning valves and transmitters

are used.

• If the ID code on the tire pressure warning valves and transmitters is

not registered in the tire pressure warning computer.

●Performance may be affected in the following situations.

• Near a TV tower, electric power plant, gas station, radio station, large

display, airport or other facility that generates strong radio waves or

electrical noise.

• When carrying a portable radio, cellular phone, cordless phone or

other wireless communication device.

●When the vehicle is parked, the time taken for the warning to start or go

off could be extended.

6

●When tire inflation pressure declines rapidly for example when a tire has

burst, the warning may not function.

368

6-3. Do-it-yourself maintenance

■The initialization operation

●Make sure to carry out initialization after adjusting the tire inflation pres-

sure.

Also, make sure the tires are cold before carrying out initialization or tire

inflation pressure adjustment.

●If you have accidentally turned the engine switch off during initialization,

it is not necessary to press the reset switch again as initialization will

restart automatically when the engine switch to the “ON” position (vehi-

cles without a smart key system) or IGNITION ON mode (vehicles with a

smart key system) for the next time.

●If you accidentally press the reset switch when initialization is not neces-

sary, adjust the tire inflation pressure to the specified level when the

tires are cold, and conduct initialization again.

■Warning performance of the tire pressure warning system

The warning of the tire pressure warning system will change in accor-

dance with driving conditions. For this reason, the system may give a

warning even if the tire pressure does not reach a low enough level, or if

the pressure is higher than the pressure that was adjusted to when the

system was initialized.

■When initialization of the tire pressure warning system has failed

Initialization can be completed in a few minutes. However, in the following

cases, the settings have not been recorded and the system will not oper-

ate properly. If repeated attempts to record tire inflation pressure settings

are unsuccessful, have the vehicle inspected by your Toyota dealer.

●When operating the initialization of the system, the tire pressure warning

light does not blink 3 times and the setting message does not appear on

the multi-information display.

●After driving for a certain period of time since the initialization has been

completed, the warning light comes on after blinking for 1 minute.

WARNING

■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.

●Do not tow if your vehicle has a compact spare tire installed.

■When initializing the tire pressure warning system

Do not initialize tire pressure warning system without first adjusting 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 normal.

371

6-3. 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.

●Make sure to install the tire valve caps. If the tire valve caps are not

installed, water could enter the tire pressure warning valves and the

tire pressure warning valves could be bound.

●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. 363)

■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.

■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 economy

●Reduced driving comfort and poor handling

●Reduced tire life due to wear

●Reduced safety

●Damage to the drivetrain

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.

It is difficult to judge if a tire is properly inflated based only on its appear-

ance.

●It is normal for the tire inflation pressure to be higher after driving as

heat is generated in the tire. Do not reduce tire inflation pressure after

driving.

●Never exceed the vehicle capacity weight.

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

balanced.

375

6-3. Do-it-yourself maintenance

WARNING

■Proper inflation is critical to save tire performance

Keep your tires properly inflated.

If the tires are not properly inflated, the following conditions may occur

which could lead to an accident resulting in death or serious injury:

●Excessive wear

●Uneven wear

●Poor handling

●Possibility of blowouts resulting from overheated tires

●Air leaking from between tire and wheel

●Wheel deformation and/or tire damage

●Greater possibility of tire damage while driving (due to road hazards,

expansion joints, sharp edges in the road, etc.)

NOTICE

■When inspecting and adjusting tire inflation pressure

Be sure to put the tire valve caps back on.

If a valve cap is not installed, dirt or moisture may get into the valve and

cause an air leak, resulting in decreased tire inflation pressure.

376

6-3. 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 a plas-

tic or rubber hammer when balancing your wheels.

■When replacing wheels

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. 363)

377

6-3. Do-it-yourself maintenance

WARNING

■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

●Be sure to install the wheel nuts with

the tapered ends facing inward.

Installing the nuts with the tapered

ends facing outward can cause the

wheel to break and eventually cause

Tapered

the wheel to come off while driving,

portion

which could lead to an accident

resulting in death or serious injury.

●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.

6

■Use of defective wheels prohibited

Do not use cracked or deformed wheels.

Doing so could cause the tire to leak air during driving, possibly causing

an accident.

378

6-3. Do-it-yourself maintenance

NOTICE

■Replacing tire pressure warning valves and transmitters

●Because tire repair or replacement may affect the tire pressure warn-

ing 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.
