WARNING

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.

■When working near the electric cooling fans or radiator grille

Vehicles without a smart key system: Be sure the engine switch is off. With

the engine switch in the “ON” position, the electric cooling fans may auto-

matically start to run if the air conditioning is on and/or the coolant tempera-

ture is high. (P. 337)

Vehicles with a smart key system: Be sure the “ENGINE START STOP”

switch is off. With the “ENGINE START STOP” switch in IGNITION ON

mode, the electric cooling fans may automatically start to run if the air condi-

tioning is on and/or the coolant temperature is high. (P. 337)

immediately after reconnecting the battery. If this happens, use the wire-

less remote control or the mechanical key to lock/unlock the doors.

●Start the engine with the “ENGINE START STOP” switch in ACCES-

SORY mode. The engine may not start with the “ENGINE START STOP”

switch turned off. However, the engine will operate normally from the sec-

ond attempt.

●The “ENGINE START STOP” switch mode is recorded by the vehicle. If

the battery is reconnected, the vehicle will return the “ENGINE START

STOP” switch mode to the status it was in before the battery was discon-

nected. Make sure to turn off the engine before disconnect the battery.

4-3. Do-it-yourself maintenance

■ 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. 399)

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 tire

pressure warning system must be initialized. Have tire pressure

warning valve and transmitter ID codes registered by your Toyota

dealer. (P. 346)

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.

346

4-3. Do-it-yourself maintenance

■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 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.

4

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

The effectiveness of snow tires is lost.

■Low profile tires

Generally, low profile tires will wear more rapidly and tire grip perfor-

mance will be reduced on snowy and/or icy roads when compared to

standard tires. Be sure to use snow tires or tire chains on snowy and/or

icy roads and drive carefully at a speed appropriate for road and weather

conditions.

347

4-3. Do-it-yourself maintenance

■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. 474)

■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. 261)

348

4-3. Do-it-yourself maintenance

■Initializing the tire pressure warning system

Initialize the system with the tire inflation pressure adjusted to the speci-

fied level.

■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.

WARNING

■Tire pressure warning system operation

The tire pressure warning system may not provide warning immediately

if a tire bursts or if sudden air leakage occurs.

■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.

●Make sure to install 4 tires that are of the specified size, and that all 4

tires are the same size, same maker, same brand and tread pattern.

●Do not use tire sizes other than those recommended by Toyota.

●Only use radial 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.

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.

351

4-3. Do-it-yourself maintenance

NOTICE

■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.

■Low profile tires and wheels

Low profile tires may cause greater damage than usual to the tire wheel

when receiving impact from the road surface. Therefore pay attention to

the following:

●Be sure to use proper tire inflation pressure. If tires are under-inflated,

they may be damaged more severely.

●Avoid pot holes, uneven pavement, curbs and other road hazards.

Failure to do so may lead to severe tire and wheel damage.

■If tire inflation pressures become low while driving

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

■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 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.

●Always use a tire pressure gauge.

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

appearance.

4

●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.

355

4-3. 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 reinstall the tire valve caps.

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.

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 inset*.

Replacement wheels are available at your Toyota dealer.

*: Conventionally referred to as “offset”.

Toyota does not recommend using:

● Wheels of different sizes or types

● Used wheels

● Bent wheels that have been straightened

■ Aluminum wheel precautions

4

● 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.

357

4-3. Do-it-yourself maintenance

■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. 346)

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 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

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.

358

4-3. Do-it-yourself maintenance

NOTICE

■Replacing tire inflation 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.

WARNING

■Replacing light bulbs

●Turn off the lights. Do not attempt to replace the bulb immediately after

turning off the lights.

The bulbs become very hot and may cause burns.

●Do not touch the glass portion of the light bulb with bare hands. When it is

unavoidable to hold the glass portion, use and hold with a clean dry cloth

to avoid getting moisture and oils on the bulb.

Also, if the bulb is scratched or dropped, it may blow out or crack.

●Fully install the light bulbs and any parts used to secure them. Failure to

do so may result in heat damage, fire, or water entering a light unit. This

may damage the light or cause condensation to build up on the inner side

of the lens.

■When changing the back-up lights

Stop the engine and wait until the exhaust pipes have cooled down suffi-

ciently. The lights are located near the exhaust pipe and touching a hot

exhaust pipe can cause burns.
