What does a lighted tire inflation indicator mean on a Toyota RAV4?

Answer 1

I have a Toyota Prius, the indicator lets you know when your tire pressure is too low. I noticed it in the beginning of fall when the mornings were chilly, and it would go away during the day (the air in the tires contracts with colder temps, resulting in lower pressure in the tire). You should check your pressure and inflate your tires if they are too low, check your owner's manual for the proper pressure for your tires.
