Hello all, I thought there was a way to listen to audio on my 2017 Prius without having to have the engine running (i.e. like we used to be able to do on a 'normal' vehicle by turning key to accessory position), though I've not been able to find anything in the owners manual. Am I mistaken? Thanks for your help!
Push "start" while NOT stepping on the brake and your Prius will go into accessory mode. It will allow you to listen to audio for a while and then shut off to protect from draining the 12v battery. JeffD
Because your 12 battery is so small, expect to need to use a jump pack to start the car if you use electricity when not in Ready.
