Sorry, I didn't notice that you had mentioned that you had already looked at the documentation. My apologies for not being more helpful.
If think that if you have a significant list of questions, perhaps it's worth another trip to the dealer for a second walk-through, this time recorded on your digital camera. This assumes he isn't too far of course. I don't think many dealers would object to you doing that.
And, as has been pointed out, please feel free to ask us if you can't make sense out of something. We have so many members, there's usually a few that have the knowledge you are looking for!
And finally, let me join in to wish you a hearty welcome
to the Forums. Always lots going on here
