I looked for an HWH Leveling manual for the 310 system.
I seemed to learn that system only lowers jacks or kick down jacks.

That would seem unusual equipment for a CC Intrigue of your vintage.
So, you also could not raise the coach with the leveling system. Only set up the jacks.
I would think a CC Intrigue will have at minimum the 600 series of leveling system using the air bags for leveling.
Perhaps I am on the wrong tangent here?
