2002 MERCEDES BENZ CLK430 Visibilitywiper Problems

WENT TO PUT MY TOP UP ON MERCEDES CABRIOLET PARKED IN MY DRIVEWAY. WITH THE KEY ON AND THE VEHICLE TURNED OFF, IN PARK, PARKING BRAKE ON, PRESSED CLOSURE BUTTON. DURING CLOSURE HEADRESTS BEGAN TO RAISE. NOT A SUDDEN POP UP KIND OF RAISING, BUT A SLOW, STEADY RAISING, AS IF I HAD MY HAND ON THE BUTTON TO RAISE THEM, YET I DID NOT. IT'S ON THE DASH, AND I WAS THE ONLY ONE IN THE CAR, AND HAD NO ITEMS IN THE CAR EITHER. FOR THE RECORD, WHILE FEMALE, I GREW UP RACING CARS, HAVE CHANGED MY OWN ENGINE, TURBO, TRANSMISSION, SHOCKS, SPRINGS, ETC. THESE TWO SEAT AND TOP PROCESSES ARE MUTUALLY EXCLUSIVE SO THEN NEITHER WOULD WORK. CLEARLY UP THEY GREATLY IMPACT VISIBILITY PLUS THE TOP WILL NOT GO UP. SECONDLY TO GET THE TOP OVER THE HEADRESTS, ACCORDING TO THE MANUAL IT'S IMPOSSIBLE, BUT SAID ANOTHER...
