I was driving my car home from church, while pulling up at walgreens I saw smoke and felt a burn on my skin...look down and there we're smoke coming out my seat through the leather. Turned off the car and it cooled the smoke.. waited a while and turned car on again but the smoke didn't return. Scared to drive car.

I started my 2006 Mercedes-Benz R350 and activated the driver seat warmer on high. After approximately 2.2 miles into my drive (speed 30-45 mph) my seat felt very hot on my lower left side near my waist line. I reached back while driving to feel how hot the seat was and was surprised by a very hot sensation as though I had touched a hot needle. As I continued to drive and pull my body forward I noticed smoke rising from behind my left shoulder. I immediately pull over onto a left side street and put the car in park leaving it running and jumped out of the seat. There was a large hole burned in the leather and it was still smoking. I patted the area down with my hand to notice a glowing orange spark and it continued to smoke. I reached in and turned off the heated seat button by cycling it though the 2nd and 3rd levels. The seat finally stopped smoking. I let the hole in the seat cool down. Checking my clothing I realized I had a hole and several melted spots on my polyester vest I was wearing. Upon coming home I noticed also a hole in my light cotton sweater that was worn under the vest two days prior to this incident I had felt the seat was hot in the same area but thought my shirt at the time was raised exposing my skin to the seat.
