n When a tires is replaced with a spare tire
The compact spare tire is not equipped with the 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 is replaced with the spare tire.
Replace the spare tire with the repaired tire and adjust the proper tire
inflation pressure.
The tire pressure warning light will turn off after a few minutes.

The tire pressure warning system may become inoperative in the follow-
ing conditions:
(When the condition becomes normal, the system will work properly.)
l If tires not equipped with tire pressure warning valves and transmit-
ters are used.
l If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
l If electronic devices or facilities using similar radio wave frequencies
are nearby.
l If a radio set at similar frequencies is in use in the vehicle.
l If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
l 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.)
l If tire chains are used.
l If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm
2
or bar) or
