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.

● Vehicles with compact spare tire: Do not tow if your vehicle has a com-

pact spare tire installed.

■When initializing the tire pressure warning system (if equipped)

Do not operate the tire pressure warning reset switch 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.

NOTICE

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

transmitters and tire valve caps (vehicles with the tire pressure

warning system)

●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 (vehicles with the tire pressure warning system)

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 repairing or replacing the tire. (→P. 571)

■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.

Inspection and adjustment procedure

1

Tire valve

2

Tire pressure gauge

1

Remove the tire valve cap.

2

Press the tip of the tire pressure gauge onto the tire valve.

3

Read the pressure using the gauge gradations.

4

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

5

adjustment, apply soapy water to the valve and check for leakage.

Put the tire valve cap back on.

6

■ 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 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.

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.

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

7

● 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.

7-3. 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

● 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.

585

■When replacing wheels (vehicles with the 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. 571)

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

ITI41P007

resulting in death or serious injury.

7

●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.

■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.
