pressure of each tire is at the speci- fied level and perform initialization. ( P.492)

Be sure to observe the following pre-
cautions. Failure to do so could cause a loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inflation
pressure adjustment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change it with
the spare tire and have the flat tire repaired by the nearest authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
