    I thought I knew most normal operations and was aware of all the beeps and tones but Priapus has introduced a new one just this week.

    Two times now, when I powered down, he beeped. No lights, no indication, nothing but a beep. Just the standard in-cabin beep; not the high-pitched MFD beep.

    There are no special conditions. Last night, for example, I stopped at a store. Level parking lot. I pressed [P] as usual and then (POWER). He beeped and shut down. The other time he did this was in my driveway. And I shouldn't need to tell you how many thousands of times I've shut down in my driveway over the last four years without incident.

    What are everyone's thoughts?

    I think I recall someone mentioning that it beeped as an indication that the 12-volt battery was getting weak.

    You might check that, just in case.

    Hi Tony,

    I suggest you replace your fob battery, if your 12V auxiliary battery is OK.

    In general it seems that 90% of Prius problems can be attributed to one weak battery or the other.

    Ahhh. I'll put the fluke on 12v and if that checks out replace the fob battery.

    Are you sure, Patrick? I think its only 89% of Prius problems. The other 11% are due to sticky throttle plates or low tire pressure. ;)

    I had a similar beep when turning the power off. It turned out that the maintenance period that I set had been reached. Check out your maintenance screen to be sure this is not the case.

    OK, here are my more detailed guestimates:

    Dead or low 12V auxiliary battery: 75%
    Dead or low fob battery: 5%
    Running out of gas: 5%
    Insufficient tire pressure: 5%
    Sticky throttle plate: 3% (less of an issue for 2G vs. Classic)
    Dead or intermittent MFD: 2%
    Miscellaneous/Other: 5%
