Tire Pressure Light Your vehicle has a tire pressure light. When the Light is Solid This indicates that one or more of your tires are significantly underinflated. A tire pressure message in the Driver Information Center (DIC), may accompany the light. See DIC Warnings and Messages on page 3-40 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 on page 5-51 for more information. This light comes on briefly when the engine is started and provides information about tire pressures and the Tire Pressure Monitoring System. When the Light Flashes First and Then is Solid This indicates that there may be a problem with the Tire Pressure Monitor System. The light will flash for about a minute and then stay on solid for the remainder of the ignition cycle. This sequence will repeat with every ignition cycle. See Tire Pressure Monitor System on page 5-59 for more information. 3-31
