If you leave it in that position, It flashes something in white, but not all the time. Then when you turn the fob to warm/pre-heat it shows the usual symbols and changes to the written pre-heat message then goes off. Haven't had any thing else. And only twice that have had the envelope show up and read them they were no big deals. I was just curious to see if others seen it or knew of it. It has been in for the recalls and it has been Flash updated. When I take it in for the tailgate I will have to ask, they might be able to read it when they hook it up to their computer.
