This is going to sound dumb but this is my first BMW and I tried to re-install the rear seat. I messed it up and locked in the front and now I can't get it off to redo it. Is there a lever/catch somewhere that will release it?? I can't find the owner's manuel ( as I took it out of the car recently and miss placed it in my house ) and I have no other info on it. I am trying to get this done before I go to sleep for work in the morning as my wife wants to use it with our newborn son but can't install the car seat till then. Any help is appricated as I need to get it done before I can go to bed.
