The horn will sound once and the TPMS indicator will flash if train mode has been entered successfully. If equipped, the message center displays "TRAIN LEFT FRONT TIRE". Place the magnet on the valve stem of the LF tire pressure sensor. The horn will sound briefly to indicate that the tire pressure sensor has been recognized by the TPMS module.
Within two minutes after the horn sounds, place the magnet on the valve stem of the RF tire pressure sensor.
NOTE: If the TPMS module does not recognize any one of the four tire pressure sensors during the tire training procedure, the horn will sound twice and the message center (if equipped) will display "TIRE TRAINING MODE INCOMPLETE". If this occurs, the entire procedure must be repeated from Step 1.
Repeat Step 7 for the RR and LR tires.
When the tire training procedure is complete, the horn will sound once and the message center (if equipped) will display "TIRE TRAINING MODE COMPLETE".
