Reclining Seatbacks

To adjust the seatback, pull up on the recliner lever
located on the outboard sides of both the driver's and
front passenger's seats. Release the lever to lock the
seatback where you want it. Push and pull on the seat to
make sure it's locked into position. Pull up on the lever,
and the seat will go to its original upright position.
