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 on page 10‑65 for more information.
