What does "w/thermal" mean?

I folded down my rear seats for the first time today, and I noticed a sticker under my seat cushions. It says "stone gas w/thermal" on it. I know what the first two terms are (stone is the color of my interior, and gas means gas-powered). Does anyone know what "w/thermal" means? I was wondering if it means I was supposed to have auto climate control, because I just have the manual, and I'd really like to have the automatic.

Here's a pic of the sticker: http://cid-6226bfb33fdc7796.office.live.com/self.aspx/Pictures/Sticker.JPG
