How does Accessory Mode work? I've checked the archive posts -- nothing appears -- at least that I understand -- might be my University of Phoenix education -- studying about birds emerging from ash tends to fog the brain. I was driving back home on Easter stuck behind a number of slow drivers. Got so bad that I pulled off a couple of times and just tried to listen to the radio. However, I have never done this before in the Prius. In my old Corolla, I just turned the key to accessory and all was fine. I realized I did not know how to reach accessory mode in the Prius. Checked the owner's manual. As usual, it was useless -- malum in se. Or maybe it is just me. The instructions might as well have been written in English. IS there an accessory mode?
Yep. ACC mode is indicated by the green light on the power button. See section 2-6 of your manual (it's on pages 140 and 142 of mine). I wouldn't leave it in that mode for too long since the 12 volt battery is small and can be run down pretty quickly. While you're in the car, I would just leave the power fully on so that you don't discharge the 12 volt.
Prius has four possible operating modes: - IG-OFF, where all systems are off. - READY, where the car can be driven. I assume you know both of these. - ACC-ON, which can be reached from IG-OFF by depressing the POWER button once without depressing the brake pedal. This is good for listening to the stereo, and is the mode that you inquired about. - IG-ON, which can be reached with an additional press of the POWER button. This can be used to raise/lower the windows and all electrical systems are available. Most dashboard warning lights appear. I recommend that you minimize use of this mode because 12V power drain is quite high.
While ACC-ON is the accessory mode, don't use it for extended periods. The Prius has a small battery, and it doesn't take well to abuse. If you stay in Ready, the car can keep the battery charged as needed. Tom
Yes, what qbee wrote! When you do that, leave the car ON, shift to Park, set the parking brake, and everything will be fine.
