If your vehicle has a power seat on the driver’s or
passenger’s side, you can adjust it with these switches at
the front center cushion of the seat.

To raise the seat, move the center knob up. To lower the
seat, move the center knob down. To move the seat
forward, move the center knob toward the right. To move
the seat rearward, move the center knob toward the left.

You can raise and lower the front and rear of the seat. To raise 
the front of the seat, move the right lever up. To lower it, 
move the right lever down. To raise the rear of the seat, move 
the left lever up. To lower it, move the left lever down.

To adjust the seatback, lift the front of this lever, which
is located at the inner edge of the seat cushion.

Move the seatback with your body and release the lever
to lock the seatback where you want it. Lean forward
and pull up on the front of the lever and the seatback
will go to an upright position.
