Wow TohperS! Thank you for your reply! I think you solved my problem! Taken directly from the owners manual.
"During a remote start, the heated or ventilated seats, if equipped, can be turned on automatically. When it is cold outside, the heated seats turn on, and when it is hot outside the ventilated seats turn on. The heated or ventilated seats are canceled when the ignition is turned on. Press the heated or ventilated seat button to use the heated or ventilated seats after the vehicle is started. The heated or ventilated seat indicator lights do not turn on during a remote start."
I could swear that the heated seats stayed on during winter once I started the vehicle but I wouldn't swear on a bible! lol I was used to my STS that when I used my remote start the heated/ventilated seats were activated & then stayed on after you started the vehicle. What did annoy me about it was that the heated/ventilated seats came on "medium" instead of high so once I started the vehicle, I would always have to cycle through to high which annoyed me. At least now, I just have to hit the button once & it is on high! lol
