I have noticed recently that there is a long beep when opening up the rear hatch. It doesn't happen all the time. When opening the hatch, I typically get a beep, beep-beep. Sometimes, I get a beep, beeeeeeeeeeeep. I can't replicate it but it typically happens when I am getting out of the drivers seat and press the hatch button on the dashboard. Has anyone experiences this? What does that extra-long beep mean?
Are these beeps coming from inside or outside the car? edit: I just perused the manual. Do you have a power 'back door'? Could have something to do with that. If so, you'll have to read the manual, I can't figure it out, and I'm not getting the power option so there's no need.
Its complicated ! If you have power back door it gets even more complicated. I suggest you get your owners manual out, or a pdf copy of it, and figure out your particular situation.
oops. Do you have a gen 5 prius or a 2020 prius implied by your signature/profile. If 2020 prius, try posting to the 2020 prius group. Good luck.
