Tire types

●

Summer tires

Summer tires are high-speed perfor-
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.
(



P.401)

■

If the tread on snow tires wears

down below 0.16 in. (4 mm)

The effectiveness of the tires as

snow tires is lost.

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.

●

Do not use tires with different

load rating and/ or speed sym-

bol than what is specified on tire

pressure label or in owner’s

manual.

6-3. Do-it-yourself maintenance

Rotate the tires in the order
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 warning sys-
tem of this vehicle adopts a 2-
type warning system



When “Adjust Pressure” is
displayed (Normal Warning)

The tire pressure warning light
comes on and a buzzer sounds
when the tire inflation pressure
becomes low due to natural air
leakage or outside temperature.
(Ways of coping:



P.517, 555)



When “Immediately Check
tire when Safe” is displayed
(Emergency Warning)

The tire pressure warning light
comes on and a buzzer sounds
when the tire inflation pressure
becomes low suddenly due to a
blowout. (Ways of coping:



P.523)

However, the system may not be
able to detect sudden tire ruptures
(bursting, etc.).
The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-informa-
tion display.
The unit can be changed.

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.

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.

• A tire has been replaced with a

tire that is not an OE (Original

Equipment) 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 speci-

fied level.

• If wheels without 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,

a tire has burst, the warning may

not function.

■

Warning performance of the tire

pressure warning system

The warning of the tire pressure

warning system will change in

accordance with the conditions

under which it was initialized. 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.

■

position.

Drive straight (with occa-
sional left and right turns) at
approximately 25 mph (40
km/h) or more for approxi-
mately 10 to 30 minutes.

When initialization is complete, the

inflation pressure of each tire will be

displayed on the multi-information

display.
Even if the vehicle is not driven at

approximately 25 mph (40 km/h) or

more, initialization can be com-

pleted by driving for a long time.

However, if initialization does not

more, park the vehicle in a safe

place for approximately 20 minutes

and then drive the vehicle again.

■

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 restart

the initialization again as initializa-

tion will restart when the power

switch has been turned to ON for

the next time.

●

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 the vehicle is driven in heavy

traffic or another situation where

other vehicles are driven close by,

it may take time for the system to

recognize the tire pressure warn-

ing valve and transmitters of your

vehicle over those of other vehi-

cles.

●

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

the beginning.

●

In the following situations, initial-

ization will not be started or was

not completed properly and the

system will not operate properly.

Perform the initialization proce-

dure again.

• If, when attempting to start initial-

ization, the tire pressure warning

light does not blink 3 times.

• If, when the vehicle has been

driven for about 20 minutes after

performing initialization, the tire

pressure warning light blinks for

approximately 1 minute and then

illuminates.

If initialization cannot be completed

after performing the above proce-

dure, contact your Toyota dealer.

Every tire pressure warning
valve and transmitter has a
unique ID code. When replacing
a tire pressure warning valve
and transmitter, it is necessary
to register the ID code.
When registering the ID codes,
perform the following procedure.

When registering ID codes

●

ID code registration is performed

while driving at a vehicle speed of

approximately 25 mph (40 km/h)

or more.

●

Before performing ID code regis-

tration, make sure that no wheels

with tire pressure warning valve

and transmitters installed are near

the vehicle.

●

Make sure to initialize the tire

pressure warning system after

registering the ID codes. If the

system is initialized before regis-

tering the ID codes, the initialized

values will be invalid.

●

ID codes can be registered by

yourself, but depending on the

driving conditions and driving

environment, registration may

take some time to complete.

●

As the tires will be warm when

registration is completed, make

sure to allow the tires to cool

before performing initialization.
