Here's the critical part if you haven't already found it:
Hitch Recognition
1. Turn on the touch pad.
2. Push the “UP” arrow (Fig. 5A) to scroll to “Auto Reconnect” option on LCD screen.
3. Push "ENTER" (Fig. 5B). The rear jacks and middle jacks (if equipped) will retract first, then the front jacks will extend to raise the trailer to the height where the auto level sequence was started.
Of course like a lot of things with our trailers, nothing is perfect. You may have to tweak the height a little bit manually to match your hitch.
One other thing is to properly calibrate "Level" to your system. If you find yourself at a level or nearly level campsite, take time to calibrate the level.
I place a carpenters level on the countertop and floor to get a reference.
You may have to manually tweak the legs to get it level if the previous Auto Level setting is wrong. Just remember not to get your wheels above the parking surface when you level the trailer.
