To initially set up the auto-leveling system on my motorhome, I first had to get the coach level and then push some buttons to let the system know the coach was level.
I found level by taping the ends of my 25-foot water hose even with a seam line on my coach, then filling the hose with water. I manually operated the jacks until the water was at the same level on both ends. To do left and right, I ran the hose under the coach and followed the same procedure.
