Looked all over the web and cant seem to find the answers, can someone tell me how the ADS ll should work?

1) height switch. Am i correct in saying there are 2 extra height positions, first red dot level one and second red dots on switch level two? If i then press the bottom of the rocker switch button twice to cancel out the 2 red dots, that should return the car to "normal" height?
2) In stationary position, (no red dots on rocker switch) is it possible to lower the car to the lower cruising speed height, it auto does at certain speed, to test it?
3) pushing the big red button locks the suspension, to lift the car from its chassis, on a car lift, correct?
4) what position should the car be in, to check the oil level between the min and max level lines on plastic bottle? This is obviously very important as it seems between the top height and the lowest height, is the difference between the bottle nearly empty and the bottle nearly full and the min / max lines are 2/3rds down the bottle.
5) what does the switch on the middle dash do? From reading, it stiffens up the suspension, ie sport mode, when on, is that correct?

If the system has no faults, can these be reset by turning the steering wheel al the way to the left and right a few times, or will i need the Star system to reset?

Thanks

As I understand it (and I've never had an ADS car):
1. Yes. That's sounds about right.
2. No.
3. No idea.
4. Not sure.
5. Yes.

To reset fault codes will require a code reader.
