I have the 4 point factory installed levelup system. When unhooking, turn the control panel ON and press the front button to extend the front landing jacks until the front of the RV is high enough to disconnect the truck and pull away. Before you pull away, make sure you're really high enough that the weight is really on the jacks. You should be able to wiggle the hitch. After pulling the truck away, press the AUTO button and the levelup does the rest. Tip: If the site is way off level, with the front sitting low, you might want to first put down blocks or boards before extending the front jacks. The shorter the jack extension, the more stable the rig will be. If the site is really, really unlevel, you may have to go to manual mode, but this usually happens only in front of my house.
When ready to hook back up, press the control panel ON button. The rear stabilizers should automatically begin retracting. If they're stuck, you can free them up by going to manual mode and extending the rear landing jacks slightly. Then go to stabilizer mode and manually retract the stabilizers. After the stabilizers are up, go to manual mode, press the retract button, and press the rear button to retract the rear jacks, at least partially. That way they won't be loaded when you next extend the front jacks.
The new units are supposed to remember the height of the front jacks before you last hit the AUTO button. I think you push the left/right buttons at the same time to get the front jacks to return to that position (not sure if you have to be in manual mode before doing this). You can also get there by going to manual mode and pressing the front button to extend the front jacks to the height to engage the hitch. I usually have to fine tune this. If your left/right alignment to the hitch is slightly off (on unlevel ground for example) you can push the left or right buttons to shift the RV slightly for better alignment.
Once you're hitched, retract the front jacks enough to put the weight on the hitch, but not enough to cause damage if the hitch didn't really lock, and test to make sure the hitch really locked. Finally go to RETRACT ALL mode and press Enter to retract all the landing jacks. Turn the control panel OFF (it will automatically shut off after a couple of minutes).
I've attached a couple of files that are reasonably current, although they may not be the latest.
