When trouble arises
■ The tire pressure warning light may come on due to natural causes
(vehicles with the tire pressure warning system)
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 tire inflation pressure will turn off the
warning light (after a few minutes).
■ When a tire is replaced with a compact spare tire (vehicles with com-
pact spare tire and the tire pressure warning system)
The compact 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 spare tire.
Replace the spare tire with the standard tire and adjust the tire inflation
pressure. The tire pressure warning light will go off after a few minutes.
■ If the tire pressure warning system is not functioning
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
● If tires not equipped with tire pressure warning valves and transmitters
are used
● If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer
● If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm
2
or bar) or
higher
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
● If electronic devices or facilities using similar radio wave frequencies are
nearby
● If a radio set at a similar frequency is in use in the vehicle
● 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 non-genuine Toyota wheels are used (Even if you use Toyota wheels,
the tire pressure warning system may not work properly with some types
of tires.)
● If tire chains are used
● 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
in the luggage room.
