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 problems arise.

●

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

●

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

◆

Installing tire pressure warning valves and transmitters

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

◆

Initializing the tire pressure warning system

■

The tire pressure warning system must be initialized in the fol-
lowing circumstances:

●

When rotating the tires.

●

When the tire inflation pressure is changed such as when chang-
ing tire size. (When there are multiple specified pressures)

●

After registering the ID codes. (

How to initialize the tire pressure warning system

Park the vehicle in a safe place and turn the engine switch off.

Initialization cannot be performed while the vehicle is moving.

Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (



P. 548)

Make sure to adjust the tire pressure to the specified cold tire infla-

tion pressure level. The tire pressure warning system will operate

based on this pressure level.

Turn the engine switch to ON.
Press and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks 3 times.

A message is displayed on the

multi-information display. Also,

“--” is displayed for inflation

pressure of each tire on the

the tire pressure warning sys-

tem determines the position.

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

Initialization is complete when the position of each tire is determined

and the inflation pressure of each tire is displayed on the multi-infor-

mation display.
Initialization may take longer than approximately 30 minutes in cer-

tain situations, such as when the vehicle is stopped for a long time at

traffic lights, etc. (

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 cannot 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.

■

When replacing the tires and wheels

If the ID code of the tire pressure warning valve and transmitter is not reg-

istered, the tire pressure warning system will not work properly. After driv-

ing for about 20 minutes, the tire pressure warning light blinks for

1 minute and stays on to indicate a system malfunction.

■

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.

■

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.

■

Maximum load of tire

Check that the number given by dividing the maximum load by 1.10 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. (

Tire types

●

Summer tires
Summer tires are high-speed performance 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 provide better traction in snow and to

be adequate for driving in most winter conditions as well as for use

year-round. All season tires, however, do not have adequate traction

performance compared with snow tires in heavy or loose snow. Also, all

season tires fall short in acceleration 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. 331)

■

Initializing the tire pressure warning system

Initialize the system with the tire inflation pressure adjusted to the speci-

fied level.

■

If the tread on snow tires wears down below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is lost.

Situations in which the tire pressure warning system may not oper-

ate 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 Equip-

ment) 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 wheel without the tire pressure warning valve and tranmitter is

used.

• If the ID code on the tire pressure warning valves and transmitter 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, 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 correctly displayed due to the radio

wave conditions, the display may be corrected by driving and changing

the radio wave conditions.

●

When the vehicle is parked, the time taken for the warning to start or go

off could be extended.

●

When tire inflation pressure declines rapidly for example when a tire has

burst, the warning may not function.

The initialization operation

●

Make sure to carry out initialization after adjusting the tire inflation pres-

sure.

Also, make sure the tires are cold before carrying out initialization or tire

inflation pressure adjustment.

●

If you have accidentally turned the engine switch off during initialization,

it is not necessary to press the reset switch again as initialization will

restart automatically when the engine switch has been turned to ON for

the next time.

●

If you accidentally press the reset switch when initialization is not neces-

sary, adjust the tire inflation pressure to the specified level when the

tires are cold, and conduct initialization again.

●

While the position of each tire is being determined and the inflation pres-

sures 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.

■

Warning performance of the tire pressure warning system

The warning of the tire pressure warning system will change in accor-

dance 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.

434

6-3. Do-it-yourself maintenance

■

When initialization of the tire pressure warning system has failed

Initialization may take longer to complete if the vehicle is driven on an

unpaved road. When performing initialization, drive on a paved road if

possible. Depending on the driving environment and condition of the tires,

initialization will be completed in approximately 10 to 30 minutes. If initial-

ization is not complete after driving approximately 10 to 30 minutes, con-

tinue driving for a while.
If the inflation pressure of each tire is not displayed after driving for

approximately 1 hour, perform the following procedure.

●

Park the vehicle in a safe place for approximately 20 minutes. Then

drive straight (with occasional left and right turns) at approximately

25 mph (40 km/h) or more for approximately 10 to 30 minutes.

However, in the following situations, the tire inflation pressure will not be

recorded and the system will not operate properly. Perform initialization

again.

●

When operating the tire pressure warning reset switch, the tire pressure

warning light does not blink 3 times.

●

After performing initialization, the tire pressure warning light blinks for

1 minute then stays on while driving about 20 minutes.

If the inflation pressure of each tire is still not displayed, have the vehicle

inspected 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.

●

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.

●

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.

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.

(



P. 515) 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 seri-

ous injury.

●

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.
