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 repair ed tire and adjust the tire inflation
pressure. The tire pressu re warning light will go off after a few minutes.
