WOW, did you just figure out how to use the off position.
I turn mine on for about a 1 or 2 miles than have to turn it off in the 05. It's been like that since new. The GF turns her seat on and leaves it on the second or third line all the way to VT.
Even in the Spec. I turn it off after a few miles. I have never gone past the 3rd line with either.
I guess she is much hotter than I am so the hot seat doesn't bother her.
