We just bought a 2013 Prius with low mileage (76,000) from a friend as our 16-year-old's first car. She does not have her permit yet, so it has not been driven much in the past 2 months. It now just showing one cell/bar on the battery icon. Will that go up once it's being driven more regularly?
On the MFD or MID? I’d drive it now and let it go back up to 6 bars (out of 8). You’ll risk bricking it if it sits for longer.
