Registering ID codes



Vehicles without a tire inflation pressure display function

Every tire pressure warning valve and transmitter has a unique ID
code. In addition to the set of tire pressure warning system sensor
ID codes initially registered to the vehicle, a second set of ID codes
can be registered.
A second set of tire pressure warning system sensor ID codes can
be registered at your Toyota dealer. When 2 sets of ID codes have
been registered, either ID code set can be selected.



Vehicles with a tire inflation pressure display function

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 codes of the tire pressure warning valve and transmitters are not

registered, the tire pressure warning system will not work properly. In this

case, after driving for about 20 minutes, the tire pressure warning light will

blink for approximately 1 minute and then illuminate 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.

■

Low profile tires (vehicles with 18-inch wheels)

Generally, low profile tires will wear more rapidly and tire grip perfor-

mance will be reduced on snowy and/or icy roads when compared to

standard tires. Be sure to use snow tires on snowy and/or icy roads and

drive carefully at a speed appropriate for road and weather conditions.

■

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. (

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. 343)

■

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 situations, 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 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 valve and transmit-

ter are used.

• If the ID codes of the tire pressure warning valve and transmitters are

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

Vehicles with a tire inflation pressure display function: If tire position

information is not correctly 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.

Initialization procedure

●

Make sure to perform the initialization procedure after adjusting the tire

inflation pressure.

Also, make sure the tires are cold before performing the initialization

procedure or adjusting the tire inflation pressure.

●

If the power switch is turned off during initialization, it is not necessary to

restart the initialization procedure from the beginning as it will begin

automatically when the power switch is turned back to ON mode.

●

If initialization has accidentally been started when it is not necessary,

adjust the tire inflation pressure to the specified level when the tires are

cold and then perform the initialization procedure again.

●

Vehicles with a tire inflation pressure display function: 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.

■

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.

■

If the tire pressure warning system is not initialized properly



Vehicles without a tire inflation pressure display function

Initialization can be completed in a few minutes. However, in the following

cases, the settings have not been recorded and the system will not oper-

ate properly. If repeated attempts to record tire inflation pressure settings

are unsuccessful, have the vehicle inspected by your Toyota dealer.

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 initialize the tire pressure warning system without first adjusting

the tire inflation pressure to the specified level. Otherwise, the tire pres-

sure 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 nor-

mal.

NOTICE

■

Repairing or replacing tires, wheels, tire pressure warning valve

and transmitters and tire valve caps

●

When removing or fitting the wheels, tires or the tire pressure warning

valve and transmitters, contact your Toyota dealer as the tire pressure

warning valve and transmitters may be damaged if not handled cor-

rectly.

●

Make sure to install the tire valve caps. If the tire valve caps are not

installed, water may enter the valves of the tire pressure warning valve

and transmitters and the valves may become stuck.

●

When replacing tire valve caps, do not replace them with metal caps or

any tire valve caps other than specified, as they may become stuck.

■

To avoid damage to the tire pressure warning valve 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. 424)

■

Driving on rough roads

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

holes.

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.

■

Low profile tires (vehicles with 18-inch wheels)

Low profile tires may cause greater damage than usual to the tire wheel

when sustaining impact from the road surface. Therefore, pay attention

to the following:

●

Be sure to use proper tire inflation pressure. If tires are under-inflated,

they may be damaged more severely.

●

Avoid potholes, uneven pavement, curbs and other road hazards. Fail-

ure to do so may lead to severe tire and wheel damage.

■

If tire inflation pressure of each tire becomes low while driving

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

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.

●

Never exceed the vehicle capacity weight.

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 on 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.

6-3. Do-it-yourself maintenance

When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset

*

.

Replacement wheels are available at your Toyota dealer.

*

: Conventionally referred to as “offset”.

Toyota does not recommend using the following:

●

Wheels of different sizes or types

●

Used wheels

●

Bent wheels that have been straightened

●

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.

■

When replacing wheels

The wheels of your vehicle are equipped with tire pressure warning valve

and transmitters that allow the tire pressure warning system to provide

advance warning in the event of a loss in tire inflation pressure. When-

ever wheels are replaced, tire pressure warning valve and transmitters

must be installed. (

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

●

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.

NOTICE

■

Replacing tire pressure warning valve and transmitters

●

Because tire repair or replacement may affect the tire pressure warn-
ing valve 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 valve and transmitters at your
Toyota dealer.

●

Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valve and transmitters may not work properly
with non-genuine wheels.

●

Be sure to install the wheel nuts with

the tapered ends facing inward.

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 serious injury.

Cleaning the air intake vent

●

Dust in the air intake vent may interfere with the cooling of the hybrid battery
(traction battery). If charging/discharging of the hybrid battery (traction bat-
tery) becomes limited, the distance that the vehicle can be driven using the
electric motor (traction motor) may be reduced and the fuel economy may
be reduced.
Inspect and clean the air intake vent periodically.

●

Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter, contact your
Toyota dealer.

P. 444)

●

After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer displayed.
After the hybrid system is started, it may be necessary to drive the vehicle
up to approximately 20 minutes before the warning message disappears. If
the warning message does not disappear after driving for appropriately 20
minutes, have the vehicle inspected by your Toyota dealer.
