Mercury Mountaineer 2002 Owner's Manual page 123

Seating and safety restraints
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.
The control is located on the
outboard side of the seat cushion.
Press front to raise or lower the
front portion of the seat cushion.
Press rear to raise or lower the rear
portion of the seat cushion.
