Tire Pressure Warning Light:

When the light comes on low tire inflation pressure is detected. Adjust tire pressure including the spare if it is equipped with a TPMS transmitter.

The light should go off within a few minutes after the tire pressure is adjusted.


Rotating tires may require the system to be initialized if the front and rear tires have different pressure specifications. Tire Pressure Warning System Initialization
