Buick 2004 Century - Manual (Page 11)

Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.
Rear Seats
Split Folding Rear Seat
If the vehicle has a split folding seat, you can gain
access to the interior of the vehicle through the trunk.
To do this, pull forward
on the seat tab, located
on the side of the rear
seat, to move the
rear seatback down.
To return the seatback to its original position, push it
back up, making sure the seat latch locks it in place.
