TPMS Reset Procedures: Notes

NOTE: The system will need to be initialized when tires are rotated; tires are replaced with tires of different pressures; tire pressure sensor and/or tire pressure monitor ECU are replaced. See INITIALIZING TIRE PRESSURE MONITOR SYSTEM . When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor IDs must be memorized by the tire pressure monitor ECU prior to system initialization. See TIRE PRESSURE SENSOR REGISTRATION .

When the tire pressure warning light and message remain on, or when they come on during driving, check tire pressure and adjust as necessary. Warning indicators should turn off a few minutes after air is put into a deflated tire.
