Air Suspension Question. Leveling too much?

[coltc]

I picked up a 2005 H2 SUT back in July.

Lately I have noticed that the compressor seems to run more than I remembered when I first got it. It could just be my imagination though.

Does this system have a leveling feature? I noticed this mostly while I'm stopped. The compressor will kick on and run for a while, then I hear an air discharge. It's like the compressor runs for a bit, stops, then something bleeds off pressure.

I really don't notice any change in ride height when this happens. The rear air lift feature still works and all. When I hit the button it lifts as normal.

I'm just wondering why the compressor seems to be running, then bleeding off air pressure more than normal.
