Reclining Seatbacks - Pontiac 2004 Grand Prix Owner's Manual

Reclining Seatbacks

The recliner levers for the driver's and passenger's front
seatbacks are located on the outboard side of each
front seat cushion.
Lift the lever to release the seatback, then move the
seatback to where you want it. Release the lever to
lock the seatback in place. Pull up on the lever without
pushing on the seatback, and the seatback will return
to an upright position.

But don't have a seatback reclined if your vehicle is
moving.
