For vehicles with the Tire Pressure Monitor System (TPMS), this light comes on briefly when the engine is started. It provides information about tire pressures and the TPMS.

When the Light Is On Steady This indicates that one or more of the tires are significantly underinflated.

A Driver Information Center (DIC) tire pressure message may also display. See Tire Messages. Stop as soon as possible, and inflate the tires to the pressure value shown on the Tire and Loading Information label.

See Tire Pressure.

When the Light Flashes First and Then Is On Steady

If the light flashes for about a minute and then stays on, there may be a problem with the TPMS.

If the problem is not corrected, the light will come on at every ignition cycle. See Tire Pressure Monitor Operation.
