etc., molded into the sidewall of
each tire.

Replace the tires if the treadwear
indicators are showing on a tire.

■

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 can-

not 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.

■

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.

■

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. (

Checking tires

404

7-3. Do-it-yourself maintenance

mance 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 pro-
vide better traction in snow and to
be adequate for driving in most win-
ter conditions as well as for use
year-round. All season tires, how-
ever, do not have adequate traction
performance compared with snow
tires in heavy or loose snow. Also,
all season tires fall short in accelera-
tion 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.

If the tread on snow tires wears

down below 0.16 in. (4 mm)

The effectiveness of the tires as

snow tires is lost.

Rotate the tires in the order

WARNING

■

When inspecting or replacing

tires

Observe the following precautions

to prevent accidents.

Failure to do so may cause dam-

age to parts of the drive train as

well as dangerous handling char-

acteristics, which may lead to an

accident resulting in death or seri-

ous injury.

●

Do not mix tires of different

makes, models or tread pat-

terns.

Also, do not mix tires of remark-

ably different treadwear.

●

Do not use tire sizes other than

those recommended by Toyota.

●

Do not mix differently con-

structed 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 previ-

ously.

NOTICE

■

Driving on rough roads

Take particular care when driving

on roads with loose surfaces or

potholes.

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.

shown.

Front

To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Do not fail to initialize the tire pres-
sure warning system after tire rota-
tion.

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.



The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
(

P.105)



If the tire pressure drops
below a predetermined level,
the driver is warned by a
screen display and a warning
light. (

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.

■

Tire inflation pressure

●

It may take a few minutes to dis-

play the tire inflation pressure

after the power switch is turned to

ON. It may also take a few min-

utes to display the tire inflation

pressure after inflation pressure

has been adjusted.

●

Tire inflation pressure changes

with temperature. The displayed

values may also be different from

the values measured using a tire

pressure gauge.

Situations in which the tire

pressure warning system may

not operate properly

●

In the following cases, the tire

pressure warning system may not

operate properly.

• If non-genuine Toyota wheels are

used.

• If a tire has been replaced with a

tire that is not an OE (Original

Equipment) tire.

• If a tire has been replaced with a

tire that is not of the specified size.

• If tire chains, etc. are installed.

• 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

much higher than the specified

level.

• If wheels not equipped with tire

pressure warning valves and

transmitter 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.

• When driving 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

If tire position information is not cor-

rectly displayed due to the radio

wave conditions, the display may be

corrected by changing the location

of the vehicle as the radio wave

conditions may change.

●

When the vehicle is stopped, the

time taken for the warning to start

or turn off may be longer.

●

When the inflation pressure of a

tire drops rapidly, for example

when a tire has burst, the warning

may not operate.

■

Warning performance of the tire

pressure warning system

The warning of the tire pressure

warning system will change in

accordance the conditions under

which it was initialized. For this rea-

son, 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 sys-

tem was initialized.

■

When initializing

●

Initialization is performed while

driving at a vehicle speed of

approximately 25 mph (40 km/h)

or more.

●

Make sure to carry out initializa-

tion after adjusting the tire inflation

pressure. Also, make sure the

tires are cold before carrying out

initialization or tire inflation pres-

sure adjustment.

●

The tire pressure warning system

can be initialized by yourself, but

depending on the driving condi-

tions and driving environment, ini-

tialization may take some time to

complete.

■

The initialization operation

●

If you have accidentally turned the

power switch off during initializa-

tion, it is not necessary to manu-

ally restart the initialization again,

as initialization will restart auto-

matically the next time the power

switch is turned to ON.

●

If you accidentally perform initial-

ization when initialization is not

necessary, adjust the tire inflation

pressure to the specified level

when the tires are cold, and con-

duct initialization again.

●

While the position of each tire is

being determined and the inflation

pressures are not being displayed

on the multi-information display, if

the inflation pressure of a tire

drops, the tire pressure warning

light will come on.

■

If the tire pressure warning sys-

tem is not initialized properly

●

In the following situations, initial-

ization may take longer than usual

to be completed or may not be

possible. Normally, initialization

completes within approximately

30 minutes.

• Vehicle is not driven at approxi-

mately 25 mph (40 km/h) or more

• Vehicle is driven on unpaved

roads

• Vehicle is driven near other vehi-

cles and system cannot recog-

nize tire pressure warning valve

and transmitters of your vehicle

over those of other vehicles

If initialization does not complete

after driving for 1 hour or more, park

the vehicle in a safe place for

approximately 20 minutes and then

drive the vehicle again.

●

If the vehicle is reversed during

initialization, the data up to that

point is reset, so perform the ini-

tialization procedure again from

■

Instructions for checking tire

inflation pressure

When checking tire inflation pres-

sure, 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

appearance.

●

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 vehi-

cle 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 seri-

ous injury:

●

Excessive wear

●

Uneven wear

●

decreased tire inflation pressure.

Wheels

If a wheel is bent, cracked or
heavily corroded, it should
be replaced. Otherwise, the
tire may separate from the

7-3. Do-it-yourself maintenance



Use only Toyota wheel nuts
and wheel nut 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 bal-
ance weights or equivalent
and a plastic or rubber ham-
mer when balancing your
wheels.

WARNING

■

When replacing wheels

●

Do not use wheels that are a dif-

ferent size from those recom-

mended 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 acci-

dent, causing death or serious

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, lead-

ing 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, caus-

ing 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 pro-

hibited

Do not use cracked or deformed

wheels. Doing so could cause the

tire to leak air during driving, pos-

sibly causing an accident.

NOTICE

■

Replacing tire pressure warn-

ing valves and transmitters

●

Because tire repair or replace-

ment may affect the tire pres-

sure warning 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 transmit-

ters at your Toyota dealer.

●

Ensure that only genuine Toyota

wheels are used on your vehi-

cle.

Tire pressure warning valves

and transmitters may not work

properly with non-genuine

wheels.
