For vehicles with the Tire Pressure Monitor System (TPMS), this light comes on

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 tire pressure message can accompany the light. See Tire Messages on page 5‑32 for more information. Stop as soon as possible, and inflate the tires to the pressure value shown on the Tire and Loading Information label. See Tire Pressure on page 10‑51 for more information.

When the Light Flashes First and Then Is On Steady

This indicates that there may be a problem with the TPMS. The light flashes for about a minute and stays on steady for the remainder of the ignition cycle. This sequence repeats with every ignition cycle. See Tire Pressure Monitor Operation on page 10‑54 for more information.
