Doesn't get very cold here very often, but right now it's a bit chilly in the Atlanta area (for us southerners, that is) and I've used the heated seats the past couple of days just to see if they worked, and I was impressed. Both the bottom and the back of the driver's seat got warm very quickly. As a matter of fact, I had to put the switch on the low position in a matter of minutes. However, I'm glad to get the info regarding the floor heat, I couldn't figure that one out at all.
