When a tire is replaced with a spare tire
Vehicles with a 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 turn off even though the flat tire has been replaced with the spare tire.
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
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.
