Got my truck back from shop yesterday from warranty work and they did a software upgrade.

I come back home no messages on dash I milked and after i milked my cows i.got in truck to head home and on the dash.

"Battery saver mode" popped up.

Can anyone tell me what that is?

Do I got 1 about to go bad or does cooler weather make it happen sometimes?

Temps last night was 16?
