PSM alert and Air Suspension warning!!! Help!
 

i went out to my car this morning (here in LA) and got started driving and 5 minutes into it, saw the red AIR SUSPENSION WARNING. then the PSM Workshop alert came up. the vehicle's riding very, very low, clearly no suspension as bumps and speedbumps are murder. What happened? anything i can do to fix this? it was cold last night for the first time in some time and rainy (in an area that is normally warm and dry)...could that be a factor?

Thanks!
