"Kraft crew".....The first time we got that warning, I had no idea what it was, since it's not in the manual that describes the dash symbols. Since it looked like an antenna, I pulled over and took a look, sure enough the Winegard powered antenna was up about a foot.
Here's what I discovered.....the power switch is mounted to the wall, beside the passenger's seat at the same height as the seatbelt. My wife accidentally hit the switch while grabbing the seatbelt. I later made a cover that velcroed onto the switch/controller that protected it from accidentally being activated.
Side note.... there is a phone app called Freightliner 24/7. The app has a photo of all the dash icons and what they mean.
