■How to initialize the tire pressure warning systemPark 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. 526)
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.
Wait for a few minutes with the eng ine switch in the “ON” position
and then turn the engine switch to the “LOCK” position.
◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Toyota dealer.

Maintenance and care
■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 su re 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. ( →P. 533)

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 engi ne 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.

CAUTION
■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 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.

Check if the fuse is blown.Normal fuse
Blown fuse
Type A and B:
Replace the blown fuse with a new fuse of an appropriate amperage rat-
ing. The amperage rating can be found on the fuse box cover.
Type C:
Contact your Toyota dealer.
■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( →P. 448)
● If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
