I HAVE SENT A COMMUNICATION TO MERCEDES-BENZ USA, LLC ON 7/15/2010, NEXT DAY AFTER MY INJURY FROM ONE OF THE CAR'S AUTOMATIC FEATURE (HEAD REST AUTOMATICALLY THRUSTS DOWN WHEN THE LEVER IS LIFTED AND SEAT MOVES FORWARD). IT'S A 2 DOOR SPORTS VEHICLE, SO IT WILL BE ALWAYS THE ACTION OF THE CONSUMER/VEHICLE OWNER TO GET IN AND OUT OF THE BACK SEATS. ON 7/14/2010 @ AROUND 1900: MY RIGHT ARM FLESH/SKIN GOT WEDGED/MANGLED INTO THE HEAD REST 'STEEL' OF THE CAR PASSENGER SEAT WHEN THE HEAD- REST-STEEL AUTOMATICALLY RAMMED/THRUST/PUSH LOWER CONTINUOUSLY DOWNWARDS; WHILE I WAS GETTING THINGS FROM THE BACK SEAT OF MY CAR-MB (MERCEDES-BENZ CLK 350, YEAR 2008 MODEL) CAR. MY OUTER RIGHT ARM AREA (ABOUT AN INCH PROXIMAL TO MY WRIST) WAS RESTING ON THAT PART OF THE SEAT WHEREIN I NEEDED TO LIFT THE LEVER/MECHANISM TO MOVE THE SEAT FORWARD WHEN THE STEEL CAUGHT MY SKIN/FLESH AND PRESSED IT INSIDE THE INSERTION CONTINUOUSLY. MY HUSBAND TOOK PHOTOS OF MY INJURY AND BROUGHT ME TO THE ER AFTERWARDS - DUE TO THE CONTUSION AND WOUND (V SHAPED) I SUFFERED FROM THE INCIDENT. MY ARM LOOKED LIKE IT WAS BURNED AND VERY SWOLLEN. I LOOKED INTO THE MERCEDES SAFETY MANUAL - AND IT DOES NOT EXPLAIN THE SAFETY PURPOSE OF THAT AUTOMATIC FEATURE OF THE MERCEDES CLK 350. I OWN 2 BRANDS OF CARS USUALLY (LEXUS AND MB) - OTHER BEST CARS - DOES NOT HAVE THIS FEATURE REALLY (SO IT'S NOT ACTUALLY A SAFETY FEATURE THAT IS PROVEN TO MEET THE SAFE OUTCOME FOR ALL VEHICLE MANUFACTURERS - WHATEVER MERCEDES INTENDS FOR IT
