I kept my 2012 rt in a heated storage unit all winter,except for the two months I spent in Clearwater, Florida. Once or twice down there in Florida, when it got quite cool and when I went to start it up it had the orange warning screen come up. I couldn't see anything on the screen that looked like a trouble or code. Now back here in Maine for the spring/summer the same thing has happened twice again. Both times it was a cool morning But I shut it off and waited until the outside temprature got to above 40/45. Go to start it and Fine, no orange screen, starts fine, nothing wrong on the screen. Something coming & going or possibly just doesn't like the cold/cool temps?
