its for resetting the TPMS ( tire pressure monitoring system) for the car to lear what wheel is where on the car. hope you got the sensors put in your new wheels or it will be driving you crazy with the low tire pressure lights and messages. columbus MT eh? im working in billings right now. see ya around maybe lol.Does anyone know what the tire learn feature does on the G6? I drive a 08 value leader and I have no idea what the tire learn does. I am putting on new rims this week so will that affect it? what is that feature for anyways?
