When raising or lowering the roof make sure that no body parts are in the vicinity of moving components. 2002 slk230 and all the switches are working fine i just rebuilt the front and and 1 trunk cylinders i do believe there is still a leak in one or two of the cylinders still. From what you have described though it sounds like your car is not equipped with the remote roof open close feature it just has the standard convience.
