Reclining the seats
Pull the lever located on the outside
of the seat to recline the seatback.
Release the lever to lock the
seatback in place.
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.
Never adjust the driver's seat or seatback when the vehicle is
moving.
Power lumbar (if equipped)
Depress the button forward to
inflate, or rearward to deflate.
