Seating and Safety Restraints
Pull lever up to adjust seatback.
Using the manual lumbar support
The lumbar support control is
located on the inboard side of the
driver's seat.
Turn the lumbar support control
clockwise to increase firmness.
Turn the lumbar support control
counterclockwise to increase
softness.
Adjusting the front power seat (if equipped)
Never adjust the driver's seat or seatback when the vehicle is
moving.
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.
