So: did my standard "precondition during breakfast" routine. Garage temps in the upper 40's, about 10 degrees warmer than yesterday morning, thanks to a big wet cold front blowing through Seattle.
Unlocked the car, removed the charger plug and closed the door. Got into the car, and the main DIC showed both the Gas and Battery icons were 'greyed out', battery showing 32 miles, gas showing 196.
The drive to work was uneventful as usual, and just for fun, I snapped a pic of the display:
I did try and influence the display to refresh, by using the 'config' button to switch things around, and even trying briefly to switch into mountain mode - thinking that trying to get the display to reread the state of the battery might cause an update, but no joy.
Anyone seen this before?
