For those of you who don't know how to release the gear lever from park in an emergency, to facilitate towing a "dead" car, (which is probably most of you), there is a small two-sided cam which looks a little like a tiny butterfly nut, on the passenger side of the J-Gate housing. To get to this, you prise off the J-Gate surround trim, insert a screwdriver down the side of the J-Gate, in front of the cam and keeping the screwdriver upright, push it rearwards. The cam is almost exactly in line with the '2' on the J-Gate.
This takes a bit of practice, but once you get the hang of it, the park lock will release and you can move the gear lever. Obviously, take steps to ensure that the car isn't going to run away when you do this. Either chock the wheels or ensure that the handbrake is applied. Cover the footbrake as well, remembering that there might not be any power assistance!
