I'd only add that you'll want to be familiar with the operation of any "econ" button that may disable auto-stop. I don't know if the 06's have this, but the HCH I's have an econ button that if you don't have it engaged, auto-stop won't work. When I test drove mine, I couldn't get auto-stop to engage and the salesman didn't know why. Realized later it was the button. You may also want to read up on how an 06 gets into "EV only" mode to maintain highway speeds if you want to check that out too. I expect there are some conditions to be met there too (engine warm, batts at a certain charge). Basically, just be familiar with the conditions necessary to enable some of the hybrid-unique features if you want to check them out.
