Reclining Seatbacks - Pontiac Sunfire 2003 Owner's Manual

Reclining Seatbacks

To adjust the seatback, lift the lever located on the
outboard side of the seat and move the seatback
to where you want it. Release the lever and push
rearward on the seatback to make sure it is locked. Pull
up on the lever without pushing on the seatback and
the seatback will go to an upright position.
