Oldsmobile 2004 Silhouette Owner's Manual page 21

To recline the seatback, lift up on the recliner lever,
located on the outboard side of the seat. Use the recliner
lever to move the seatback to the desired position.
It is easier to raise or lower the seatback if you lean
forward, taking the weight off the seatback.
The seatbacks on the second row captain's chairs also
fold forward to put items behind the left and right seats.
Lift up on the recliner lever and fold the seatback
forward. The seatback will lock into place when you
push it back to the upright position.
The armrests can be lowered or raised for entering
or exiting the vehicle.
