How do I swivel the seat at the end of the rail?

The lift stops automatically at the end of the rail. Push down the lever to swivel the seat manually, making it easier to get on and off. Swivel the seat until you hear a 'click'—the seat is now in the correct position. With the optional powered swivel, you can swivel the seat automatically by pushing and holding the joystick in the direction of travel. (Page 4)
