Tire pressure warning system

Your vehicle is equipped with a tire pressure warning system that uses

tire pressure warning valve 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.

*: If equipped

*

● 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 valve and transmitters

When replacing the tires or wheels, the tire pressure warning valve

and transmitters must be installed to the wheels which will be

installed to the vehicle.

When new tire pressure warning valve 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. (P. 431)

◆ Initializing the tire pressure warning system

■ The tire pressure warning system must be initialized in the fol-

lowing circumstances:

● When the tire inflation pressure is changed such as when chang-

ing traveling speed or load weight.

● When the tire inflation pressure is changed such as when the tire

size is changed.

● When rotating the tires.

● After performing the transmitter ID code registration procedure.

(P. 431)

When the tire pressure warning system is initialized, the current tire

inflation pressure is set as the benchmark pressure.

■ How to initialize the tire pressure warning system

1

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

The initialization procedure cannot be started while the vehicle is

moving.

2

Adjust the tire inflation pressure to the specified cold tire inflation

pressure level. (P. 532)

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.

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 1 hour in certain

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

traffic lights, etc. (P. 436)

◆ Registering ID codes

■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.

■Replacing 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.

6

■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. (P. 537)

■Tire types

6-3. Do-it-yourself maintenance

●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)

■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 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.

■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.

• 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 the spare tire is in a location subject to poor radio wave signal

reception.

• If a large metallic object which can interfere with signal reception is

put near the spare tire.

• If tires not equipped with the tire pressure warning valves and trans-

mitters 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, large

display, airport or other facility that generates strong radio waves or

electrical noise

6

• When carrying a portable radio, cellular phone, cordless phone or

other wireless communication device

●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.

6-3. Do-it-yourself maintenance

■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 IGNI-

TION ON mode 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.

■When initialization of the tire pressure warning system has failed

●Do not move the vehicle backward during initialization. Initialization is

started again from the beginning and it may take longer than usual.

●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, initial-

ization will be completed in approximately 10 to 30 minutes.

• If initialization is not complete after driving approximately 30 minutes,

continue driving for a while.

• If initialization is not complete after driving approximately 1 hour, 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.

• If initialization is still not complete, have the vehicle inspected by your

Toyota dealer.

*: Except when making a left/right turn

●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 pres-

sure warning light does not blink 3 times.

• After performing initialization, the tire pressure warning light blinks for

1 minute then stays on after driving for about 20 minutes.

■When ID code registration has failed

●Registration may take long time or the ID codes may not be registered in

the following situations.

• When the vehicle is moved backward during registration.

Registration is started again from the beginning and it may take lon-

ger than usual.

• When another vehicle is running the side of the vehicle such as in

heavy traffic.

It may take longer to detect the vehicle’ tire pressure warning valves

and transmitters.

• If tire pressure warning valves and transmitters are in the vehicle.

The ID codes may not be registered.

●When performing registration, drive on a paved road if possible.

Depending on the driving environment and condition of the tires, regis-

tration will be completed in approximately 10 to 30 minutes.

• If registration is not complete after driving approximately 30 minutes,

continue driving for a while.

• If registration is not complete after driving approximately 1 hour, park

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

straight (with occasional left and right turns) at approximately 40 km/h

(25 mph) or more* for approximately 10 to 30 minutes.

If registration is still not complete, have the vehicle inspected by your

●When the tire pressure warning light does not blink slowly 3 times, the

ID code will not be registered and the system will not operate properly.

Perform registration again.

■When registering ID codes

●Initialize the tire pressure warning system after ID code registration. Ini-

tialization is disabled if the system was initialized before registration.

●After ID code registration, the tires are hot by driving. Initialize the tire

pressure warning system after the tires become cold.

■Canceling the change wheel set mode

●If turning the engine switch off when in the change wheel set mode

before driving, the change wheel set mode is canceled.

●After driving when in the change wheel set mode, the change wheel set

mode cannot be canceled. To cancel the mode, perform the procedure

for ID code registration again and turn the engine switch off before driv-

ing.

●If the change wheel set mode is canceled, the ID codes that have

already been registered are communicated. When communication is fin-

ished, the tire pressure warning light will turn off.

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 operate the tire pressure warning reset switch without first

adjusting the tire inflation pressure to the specified level. Otherwise, the

tire pressure 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 normal.

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. Make sure to replace the tire pressure warning valve and

transmitter when replacing the tire. (P. 430)

■Driving on rough roads

Take particular care when driving on roads with loose surfaces or pot-

holes.

6

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.

■If tire inflation pressure of each tire becomes low while driving

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