Energy Screen Flips into Alternate Screen

I have an 08 Prius with about 3K miles driven. I just noticed today the energy screen (mine is type A) suddenly flipped into another energy screen while I was driving. The new screen had the outside temp across the top instead of the upper RH corner of the normal screen. The engine/battery/wheels diagram was pushed down just below it--everything else the same. Mileage across bottom. After a minute or two, the normal screen returned. And then it flipped again and returned a few minutes later.

Has anybody seen this before? The new screen is not in the manual (not type B).

It was cold this morning--about 39 F. And this is my first cold season. I also don't drive a lot--about 3K miles in 6 months. And I wonder about the battery, though I had already driven about 15 miles before I noticed the screen flip. This was on the return home after parking for about an hour.

I called the dealership about it, and am awaiting a return call.

 

That exactly right. I just talked to an 08 Prius owner who works at my dealership, and he says it's normal when the temp drops below 37 F. His '08 does the same screen flip as mine. It's a puzzle to both of us that it's not in the handbook. I mentioned your reply in my phone conversation a few minutes ago.

Thanks.
