Your computer has detected a problem in your air ride suspension. If is most likely either a height sensor but could be the compressor or air bags.

Does the system drain down overnight? That could mean a valve or a small tear in the air bag or even an air line. If the compressor brings it back up when you start the vehicle that would tell you the compressor is good, or at least not the problem.

Suncore Industries at www.suncoreindustries.com has some very good explanations on how the system is susposed to work and has some troubleshooting tips.

This sounds like the A/C developed a leak and the safety switch won't let the compressor engage due to low refrigerant. It's probably time to take it to a service center and have the A/C checked for leaks and refrigerant level. You don't need anything off the internet until this check is completed.
