"This bulletin announces availability of reprogramming files to optimize operation of the Tire Pressure Monitor Systemâs (TPMS) real-time display function. Under certain high-altitude conditions, the tire pressure values displayed in the combination meter may
not be accurate. NOTE: The TPMS Real Time display is independent of the actual TPMS function. Should an actual low tire pressure condition occur, the TPMS indicator light will illuminate as expected."
