This light will also come on when one or more of your tires are significantly underinflated.
Stop and check your tires as soon as it is safe to do so. If underinflated, inflate to the proper pressure. See Tires for more information.
This light will flash for about one minute and then stay on if a problem is detected with the Tire Pressure Monitor system.
