RE: 03 Rear seat removal
There are 2 push-in type clips under the seat. The are located on each side of the seat, in center of where one would normally sit but close to the front edge of the seat. Place you hands under the seat on each side of the clip then pull up to disengage the clip.
Once both clips are disengaged, pull forward on the seat to remove.
To install the seat, reverse the order.
