WARNING

■

When inspecting or replacing

tires

Observe the following precautions to
prevent accidents.

Failure to do so may cause damage

to parts of the drivetrain as well as
dangerous handling characteristics,

which may lead to an accident result-

ing in death or serious injury.

364

6-3. Do-it-yourself maintenance

Rotate the tires in the order shown.

Front

To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).

When rotating front and rear tires which
have different tire inflation pressures,
do not fail to initialize the tire pressure
warning system after tire rotation.

Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla-
tion pressure before serious prob-
lems arise.
The tire pressure warning system
of this vehicle adopts a 2-type
warning system.



When “Adjust Pressure” is dis-
played (Normal Warning)

A warning with the tire pressure warn-
ing light and warning buzzer when
there is an unknown level of low tire
pressure with the appearance of the tire
due to natural air leakage as well as the

the pressure according to the outside

WARNING

●

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.

NOTICE

■

If tire inflation pressure of each
tire becomes low while driving

Do not continue driving, or your tires

and/or wheels may be ruined.

■

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 addi-

tion, driving on rough roads may
cause damage to the tires them-

selves, as well as the vehicle’s

wheels and body.

Situations in which the tire pres-
sure warning system may not oper-

ate properly

●

In the following cases, the tire pres-

sure 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 specified
level.

• If tires not equipped with tire pressure

warning valves and transmitters are
used.

• If the ID code on the tire pressure

warning valves and transmitters is not

Warning performance of the tire

pressure warning system

The warning of the tire pressure warning
system will change in accordance with

driving conditions. 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.

When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.

■

If the tire pressure warning system

is not initialized properly

●

In the following situations, initialization

may take longer than usual to be com-

pleted or may not be possible. (Usu-
ally, the vehicle will need to be driven

for approximately 10 to 30 minutes to

complete initialization.) If initialization
is not complete after driving approxi-

mately 30 minutes, continue driving

for a while.

• If the vehicle is driven on an unpaved

road, it may take longer to complete

initialization.

• If the vehicle is backed up while per-

forming initialization, data collected

during initialization will be cleared and
it will take longer than normal to com-

plete.

• If the vehicle is driven in heavy traffic

or another situation where other vehi-

cles are driven close by, it may take

time for the system to recognize the
tire pressure warning valve and trans-

mitters of your vehicle over those of

other vehicles.

If initialization is not complete after driv-
ing for approximately 1 hour, park the
vehicle in a safe place for more than 15
minutes and then drive the vehicle
again.

●

In the following situations, initialization

will not be started or was not com-
pleted properly and the system will not

operate properly. Perform the initial-

ization procedure again.

• If, when attempting to start initializa-

tion, 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
