■The tire pressure warning light ma y 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 temper-
ature. In this case, adjusting the ti re inflation pressure will turn off the
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 pressu re 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 ti re pressure warning light will turn off
after a few minutes.
