Height is speed dependent. For example, at the middle setting, you’ll see it automatically lower once you go above about 35 mph
It adjusts from normal ride height to aero at ~60mph not 35mph. It should go back to NRH when you slow down to 30mph.
It's also not totally dependent on speed. If you are in sport mode it will be in aero mode no matter what speed. Similar behavior for the off-road settings.
I have an overland and will get strange messages like ride height not permitted when it's in aero mode even though I never go fast enough for aero mode. Happens even if I'm parked. I also get air suspension cooling down messages frequently.
Car was at the dealership for 44 days while they tried to fix it. Replaced everything, compressor, valve body, air lines, sensors, air bags and it still does this stuff. I don't think it's working correctly but I guess it might be.
