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.

■

When initializing the tire pressure warning system

Do not initialize the tire pressure warning system 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 nor-

mal.

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. After use of liquid sealant, make sure to replace the tire

pressure warning valve and transmitter when repairing or replacing the

tire. (

P. 522)

■

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 (vehicles with 215/45R17 tires)

Low profile tires may cause greater damage than usual to the 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 can lead to severe tire and wheel damage.

■

If tire inflation pressure of each tire becomes low while driving

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

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

●

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.

Wheels

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

●

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.

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.

6-3. Do-it-yourself maintenance

■

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. 522)

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

●

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.

●

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.

When the tire pressure warning light comes on

Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured:

P. 599, 619

If the tire is not punctured:
Check the tire inflation pressure and adjust to the appropriate level. Initial-

izing the tire pressure warning system will not turn off the tire pressure

warning light.

■

The tire pressure warning light may come on due to natural causes

The tire pressure warning light may come on due to natural causes such

as natural air leaks and tire inflation pressure changes caused by tem-

perature. In this case, adjusting the tire inflation pressure will turn off the

warning light (after a few minutes).

■

When a tire is replaced with a spare tire

Vehicles with compact spare tire: The compact spare tire is not equipped

with a tire pressure warning valve and transmitter. If a tire goes flat, the

tire pressure warning light will not turn off even though the flat tire has

been replaced with the spare tire. Replace the spare tire with the repaired

tire and adjust the tire inflation pressure. The tire pressure warning light

will go off after a few minutes.
Vehicles with full-size spare tire: The spare tire is also equipped with a tire

pressure warning valve and transmitter. The tire pressure warning light

will turn on if the tire inflation pressure of the spare tire is low. If a tire goes

flat, the tire pressure warning light will not turn off even though the flat tire

has been replaced with the spare tire. Replace the spare tire with the

repaired tire and adjust the tire inflation pressure. The tire pressure warn-

ing light will go off after a few minutes.

WARNING

■

When the electric power steering system warning light comes on

When the light comes on yellow, the assist to the power steering is
restricted. When the light comes on red, the assist to the power steering is
lost and handling operations of the steering wheel become extremely
heavy. When steering wheel operations are heavier than usual, grip the
steering wheel firmly and operate it using more force than usual.

■

If the tire pressure warning light comes on

Be sure to observe the following precautions. Failure to do so could

cause a loss of vehicle control and result in death or serious injury.

●

Stop your vehicle in a safe place as soon as possible. Adjust the tire

inflation pressure immediately.

●

Vehicles with emergency tire puncture repair kit: If the tire pressure

warning light comes on even after tire inflation pressure adjustment, it

is probable that you have a flat tire. Check the tires. If a tire is flat,

repair the flat tire by using emergency tire puncture repair kit.

●

Vehicles with spare tire: If the tire pressure warning light comes on

even after tire inflation pressure adjustment, it is probable that you

have a flat tire. Check the tires. If a tire is flat, change it with the spare

tire and have the flat tire repaired by the nearest Toyota dealer.

●

Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,

you could lose control of the steering wheel or the brakes.

■

If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.

WARNING

■

Maintenance of the tires

Each tire, including the spare (if provided), should be checked monthly

when cold and inflated to the inflation pressure recommended by the

vehicle manufacturer on the vehicle placard or tire inflation pressure

label (tire and load information label). (If your vehicle has tires of a dif-

ferent size than the size indicated on the vehicle placard or tire inflation

pressure label [tire and load information label], you should determine

the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire

pressure monitoring system (TPMS-tire pressure warning system) that

illuminates a low tire pressure telltale (tire pressure warning light) when

one or more of your tires is significantly under-inflated. Accordingly,

when the low tire pressure telltale (tire pressure warning light) illumi-

nates, you should stop and check your tires as soon as possible, and

inflate them to the proper pressure. Driving on a significantly under-

inflated tire causes the tire to overheat and can lead to tire failure.

Under-inflation also reduces fuel efficiency and tire tread life, and may

affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-

stitute for proper tire maintenance, and it is the driver’s responsibility to

maintain correct tire pressure, even if under-inflation has not reached

the level to trigger illumination of the TPMS low tire pressure telltale (tire

pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-

ing system) malfunction indicator to indicate when the system is not

operating properly. The TPMS (tire pressure warning system) malfunc-

tion indicator is combined with the low tire pressure telltale (tire pressure

warning light). When the system detects a malfunction, the telltale will

flash for approximately one minute and then remain continuously illumi-

nated. This sequence will continue upon subsequent vehicle start-ups

as long as the malfunction exists. When the malfunction indicator is illu-

minated, the system may not be able to detect or signal low tire pres-

sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-

ety of reasons, including the installation of replacement or alternate tires

or wheels on the vehicle that prevent the TPMS (tire pressure warning

system) from functioning properly. Always check the TPMS (tire pres-

sure warning system) malfunction telltale after replacing one or more

tires or wheels on your vehicle to ensure that the replacement or alter-

nate tires and wheels allow the TPMS (tire pressure warning system) to

continue to function properly.
