Tire Pressure Light

This light will come on briefly when you turn the ignition to RUN.
This light will also come on when one or more of your tires are significantly underinflated.
A CHECK TIRE PRESSURE DIC message will accompany the light.
Stop and check your tires as soon as it is safe to do so. If underinflated, inflate to the proper pressure.
This light will flash for approximately 70 seconds and then turn on solid if a problem is detected with the Tire Pressure Monitor system.
