The front seat adjustment lever
To recline the front manual seats:
1. On the side of the seat, find the handle for
the recliner.
2. Lift the handle up and hold it in place.
3. Lean against the back of the seat and adjust
it to the position you want. You can tilt the
seat back or bring it forward.
4. Release the handle to lock the seat in its new
position.
NOTE: Seat back recline angle is restricted to
prevent interference with interior trim
panels on convertible models.
Never adjust the driver's seat or seatback
when the vehicle is moving.
Always drive and ride with your seatback
upright and the lap belt snug and low
across the hips.
