Following the instructions on page 217 of the owner's manual for my 2023 PP, I push the ((D)) menu button, and I see a row of icons. On my mirror, there are more icons than the ones shown in the manual. I am unsure as to what the extra ones do. Left to right, the ones I have are brightness, as in manual up/down, as in manual left-right, as in manual rotate, as in manual zoom, as in manual A in sunburst icon. Pressing the ((C)) select button toggles something (what?) on and off. anti-glare, as in manual house icon with "setup" legend. I think it allows configuration of the garage-door opener tranceiver. globe icon. Pressing the ((C)) select button cycles through English/French/Spanish, but I don't know which portion of the car's UI is affected. Is there a more recent manual? The one I have is footered PRIUS PRIME_OM_OM47E73U_(U).
Interestingly, the "A" in a sunburst is mentioned in the 2024 Prius Prime US/Canada owner's manual but not the 2023 one (downloaded just now, from the US website): So it allows you to change the anti-glare function of the optical mirror while in digital mode. As to what the language setting changes I'm not sure, but maybe it's the on/off text that shows up in optical mirror mode: Otherwise, I don't see any references to any text that is displayed in digital mode. (And also my vehicle doesn't have the digital rearview mirror, but I was curious about this.)
