Strange Dashboard Behavior

[Ventana]

I went to move my 2017 Ventana 3412 into its new sheltered home. Temperature was 31F when I started the coach. I noticed while it was airing up that the battery gauge was bouncing back and forth between 12 and 14 volts. By the time I got the phone out to video it, I was only able to get the last little bit before it settled down. I'm guessing it cycled back and forth 7 or 8 times. Upon reviewing the video I noticed one of the DEF level indicators flashing. By the end of the video everything settled down and the coach drove fine.

Any guesses as to what was happening?

I can only assume some of the circuitry needed to be warmed up?

Since the ambient temperature was 31 degrees, it may have been below freezing earlier and the DEF heater was functioning to get rid of crystals in the DEF fluid. (This is just a guess)
