When trouble arises
■When the tire pressure warning light comes on
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 673, 687
If the tire is not punctured:
Check the tire inflation pressure and adjust to the appropriate level. Push-
ing the tire pressure warning reset switch will not turn off the tire pressure
warning light.
■The tire pressure warning light may come on due to natural causes
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 ti re inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire
Vehicles with 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 tu rn 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 full-size spare tire: The spare tire is also equipped with a 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, 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 warn-
ing light will go off after a few minutes.
■Conditions that the tire pressure warning system may not function
properly
P. 6 1 1
■If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for
1 minute when the power switch is tu rned to ON mode, have it checked
by your Toyota dealer.
■ Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location
or audio sound.
