Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 517)
Make sure to adjust the tire pressu re 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 the “ON” position.
Press and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks slowly 3 times.

Maintenance and care
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, largedisplay, 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 a radio set at similar frequencies is in use in the vehicle
●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 in itialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold be fore 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 the
“ON” position for the next time.
●If you accidentally press the reset s witch when initialization is not neces-
sary, adjust the tire inflation pressu re to the specified level when the
tires are cold, and conduct initialization again.
■When initialization of the tire pr essure warning system has failed
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.
●When operating the tire pressure wa rning reset switch, the tire pressure
warning light does not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warning
light blinks for 1 minute then stays on after driving for about 20 minutes.

■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 ma kes, 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 ti res (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.

When trouble arises
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Push-
ing the tire pressure warning reset switch will not turn off the tire pressure
warning light.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti re inflation pressure will turn off the
warning light (after several minutes).
■When a tire is replaced with a spare tire
The temporary spare tire is not equipped with a tire pressure warning
valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire has been replaced with the temporary
spare tire. Replace the temporary spare tire with the repaired tire and
adjust the tire inflation pressure. Th e tire pressure warning light will go off
after several minutes.
■Conditions that the tire pressure warning system may not function
properly
 P. 4 2 0
■If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1
minute when the engine switch is turned to “ON” position, have it checked
by your Toyota dealer.
■Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.

4888-2. Steps to take in an emergency
Keep winding until three clicks
are heard. It is not possible to
overtighten.

Repeat step , any time the tire is lowered or disturbed.
Stow the tools and jack securely.
■The temporary spare tire
●The temporary spare tire is identified by the label “TEMPORARY USE
ONLY” on the disc wheel.
Use the temporary spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the temporary spare
tire. ( P. 517)
■After completing the tire change
The tire pressure warning system must be reset. ( P. 418)
■When reinstalling the wheel ornament (on some models)
P. 4 2 8
■When using the temporary spare tire
As the temporary spare tire is not equipped with the tire pressure warning
valve and transmitter, lo w inflation pressure of the spare tire will not be
indicated by the tire pressure warning system. Also, if you replace the
temporary spare tire after the tire pressure warning light comes on, the
light remains on.
■If you have a flat rear tire on a road covered with snow or ice
Install the temporary spare tire on one of the front wheels of the vehicle.
Perform the following steps and fit tire chains to the rear tires:
Replace a front tire with the temporary spare tire.
Replace the flat rear tire with the tire removed from the front of the
vehicle.
