You have the standard level low, unless modified. Very simple, the rotary switch selects front, left, right and drive. Then you have a button for up and down. The front position raises and lowers both front air bags. The left/right raises and lowers the particular side selected and all 3 air bags on that side raise or lowers. The drive position is selected for driving and road height is then controlled by the ride height valves automatically.
