When the tire pressure warning light comes on

tire pressure warning light comes on or flashes.
If the tire pressure warning light comes on
After the temperature of the tires has lowered sufficiently, check the
1
inflation pressure of each tire and adjust them to the specified level.
If the warning light does not turn off even after several minutes have
2
elapsed, check that the inflation pressure of each tire is at the specified
level and perform initialization. (P. 483)
If the warning light does not turn off even after several minutes have
elapsed, have the vehicle inspected by your Toyota dealer immediately.

There may be a malfunction in the tire pressure warning system. Have

■
The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such as
natural air leaks or tire inflation pressure changes caused by tempera-
ture. In this case, adjusting the tire inflation pressure will turn off the warn-
ing light (after a few minutes).
■
When a tire is replaced with a spare tire
The spare tire is also equipped with the tire pressure warning valve and
transmitter. The tire pressure warning light will turn on if the tire inflation
pressure of the spare tire is low. If a tire goes flat, even though the flat tire
is replaced with the spare tire, the tire pressure warning light does not
turn off. 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.
