This light comes on briefly when you turn the ignition to RUN.
It will also come on when one or more of your tires are significantly underinflated.
If your vehicle has a Driver Information Center (DIC), a CHECK TIRE PRESSURE message will accompany the light. See DIC Warnings and Messages for more information.
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 60 seconds and then stay on if a problem is detected with the Tire Pressure Monitor system.
