elsifer — Yes indeed, after switching to ACC mode from Drive or Neutral, you can move the selector to Park and it will stay in ACC mode. The only place I found this was on an information card attached with string to the gear shift lever when I received the car. I guess they forgot to put it in the Owner's Manual. Maybe the dealer removed yours?

Orcrone — The Ready light in the instrument cluster will be "off" when you're in either ACC or ON mode. It will be "on" in the normal "ready to drive" mode. The ON mode appears to mimic the "on" state of a non-hybrid car — all the instruments are "on" but the engine is not running. The Ready light appears intended to show that you're beyond ON, by mimicking the "engine running and ready to drive" state of a non-hybrid.
