When registering ID codes (vehicles with a tire inflation pressure dis-
play function)

●

Before performing ID code registration, make sure that no wheels with

tire pressure warning valve and transmitters installed are near the vehi-

cle.

●

Make sure to initialize the tire pressure warning system after registering

the ID codes. If the system is initialized before registering the ID codes,

the initialized values will be invalid.

●

As the tires will be warm when registration is completed, make sure to

allow the tires to cool before performing initialization.

■

Canceling ID code registration (vehicles with a tire inflation pressure
display function)

●

To cancel ID code registration after it has been started, turn the engine

switch off before driving the vehicle.

If the vehicle is driven after ID code registration is started, to cancel reg-

istration, perform the ID code registration start procedure again and turn

the engine switch off before driving.

●

If ID code registration has been canceled, the tire pressure warning light

will blink for approximately 1 minute when the engine switch is turned to

the “ON” position (vehicles without a smart key system) or IGNITION

ON mode (vehicles with a smart key system) and then illuminate. The

tire pressure warning system will be operational when the tire pressure

warning light turns off.

●

If the warning light does not turn off even after several minutes have

elapsed, ID code registration may not have been cancelled correctly. To

cancel registration, perform the ID code registration start procedure

again and then turn the engine switch off before driving.

■

If ID codes are not registered properly (vehicles with a tire inflation
pressure display function)

●

In the following situations, ID code registration may take longer than

usual to be completed or may not be possible. (Usually, the vehicle will

need to be driven for approximately 10 to 30 minutes to complete ID

code registration.) 

If ID code registration is not complete after driving for approximately 30

minutes, continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer than

normal to complete registration.

• If the vehicle is backed up while performing registration, data col-

lected during registration will be cleared, and it will take longer than

normal to complete.

• 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 recog-

nize the tire pressure warning valve and transmitters of your vehicle

over those of other vehicles.

• If a wheel with a tire pressure warning valve and transmitter installed

is inside or near the vehicle, registration of the ID codes for the

installed wheels may not be possible.

If ID registration is not complete after driving for approximately 1 hour,

park the vehicle in a safe place for approximately 20 minutes and then

perform the ID code registration procedure again.

●

In the following situations, ID code registration will not be started or was

not completed properly and the system will not operate properly. Per-

form the ID code registration procedure again.
• If, when attempting to start ID code registration, the tire pressure

warning light does not blink slowly 3 times.

• If, when the vehicle has been driven for about 20 minutes after per-

forming ID code registration, the tire pressure warning light blinks for

approximately 1 minute and then illuminates.

●

If ID code registration cannot be completed after performing the above

procedure, contact 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.
