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 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

■
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 min-
utes.
