RE: Disconnected battery
Not one mention of MDS in my manual. I have read a procedure on the forums to reset the MDS system, as I recall it involved driving up to a certain speed and crusing there for some time and then stopping and restarting the car. It was dismissed in the thread as unneccessary and I would agree. The computer is adaptive and would adjust to set any paramaters neccessay for proper operation over time. It's not like the computer will lose it's program because the battery was disconnected. Just keep driving, any problems like poor fuel mileage should become apparent shortly and you can take it in with a specific complaint. I think the lack of specific knowledge for this from the dealer points to how little importance it really is. Call a few more dealers and see if any have a real knowledge of why a service visit is neccessay, may set your mind at ease.
