I know this must seem like a really dumb question. Only have had the car a few weeks. Owners manual shows battery under back seat. I can't seem to get the back seat up. Manual shows a 60/40 split. I have one big seat that looks like two seat forms and a big arm rest. I do have a middle seatbelt though. Can seem to find those pull straps the manual shows. Thanks in advance for any advice. Steve
