The tire pressure warning light may come on due to natural causes

(vehicles with a 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 temperature.
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 spare tire (vehicles with a tire pressure
warning system)
 Vehicles with a compact spare tire
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 repaired tire and adjust the tire inflation pressure. The tire
pressure warning light will go off after a few minutes.

Vehicles with a full-size spare tire
The spare tire is also equipped with a tire pressure warning valve and trans-
mitter. The tire pressure warning light will turn on if the tire inflation pressure
of the spare tire is low. 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 repaired tire and adjust the tire inflation pres-
sure. The tire pressure warning light will go off after a few minutes.
■ Conditions that the tire pressure warning system may not function prop-
erly (if equipped)

■ If the tire pressure warning light frequently comes on after blinking for 1

ute when the engine switch is turned to the "ON" position (vehicles without a
smart entry & start system) or the engine switch is turned to IGNITION ON
mode (vehicles with a smart entry & start system), have it checked by your
Toyota dealer.
