changed tires and low air light (TPM Light) stayed on.
The TPMS – Tire Pressure Monitor System will need to be reset.
When the tire pressure warning light comes on solid and the message center displays “LOW TIRE PRESSURE”, check the air pressure of all tires and adjust to the specified cold pressure listed on the vehicle certification label (found on the driver’s door or door pillar). Drive the vehicle at 20 MPH for at least 2 minutes. If the vehicle has been stationary for more than 30 minutes, the sensor will enter into “SLEEP MODE” and stop transmitting. A TPM Sensor activation procedure may be needed.
If one or more tire pressure sensors are replaced, it will need to be trained.
If the warning light stays on, there is a malfunction in the TPM System. See the appropriate manufacturer service information.
