Lincoln 2004 Aviator Owner's Manual page 167

Do not pile cargo higher than the seatbacks to avoid injuring
people in a collision or sudden stop.
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.
Reclining the seatback can cause an occupant to slide under the
seat's safety belt, resulting in severe personal injuries in the
event of a collision.
Press to move the seat forward or
backward.
Press to move the front portion of
the seat cushion up or down.
Press to move the rear portion of
the seat cushion up or down.
