Buick 2007 Rendezvous Owner's Manual page 25

Do not put the seats in so that they face rearward
because they will not latch that way. The captain
chairs have seat position labels, located on
the back of each seat, showing where that seat
must go. The seat must be placed in the
proper location for the legs to attach correctly.
1. Make sure that the seatback is in the folded
forward position and that the safety belts are
on the correct side of the seat.
2. Hook the front latches over the front floor pins.
