This might seem weird, but I think my '97 C230 has an inflatable lumbar support that I can not figure out how to operate. I noticed after a long trip with my brother that something was digging into my back, and he told me (I bought the car from him) to hold the height adjustment for the seat (front and back) down for a few seconds and, to my surprise, I could feel the lumbar support deflating. I can't find anything about this in the owner's manual; it just has the standard power seat, not the multi-countour upgrade. What's more, my brother can't remember how to inflate it... does anyone have any suggestions. I am happy with it the way it is, but you know... "Enquiring Minds" wanna know!
