Lippert leveling system question

[gdog]

I recently purchased the Alpine 3500RE and now that the leveling system is wired correctly, I use the auto level with a little more confidence.
But after watching a Youtube video on the leveling system, I saw it has a feature where you can hit the left and right buttons together and it is supposed to take the coach back to the point where you hit the auto level button when you're ready to hook up to the tow vehicle to leave.
Well when I hit those buttons together on my unit I get an error of "feature disabled". Any idea how I can "enable" this feature? I see nothing in the manuals I have looked at.

Thanks,

G
