■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. 5 6 0
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered sufficiently.
●Check the tire inflation pressure and adjust to the appropriate level.
●If the warning light does not go out even after several minutes, check that the tire infla-
tion pressure is at the specified level and carry out initialization. ( P. 5 0 4 )
The warning light may come on again if the above operations are conducted without first
allowing the tire temperature to lower sufficiently.
■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 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 compact spare tire: The comp act 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 ha s 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 transmitter. The tire pressure warning light will turn on if the tire infla-
tion 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
warning light will go off after a few minutes.
