Head Restraints
Slide the head restraint up or down so that the top of the
restraint is closest to the top of your ears. This position
reduces the chance of a neck injury in a crash.
Split Folding Rear Seat (If Equipped)
This feature enables you
to access your trunk.
Pull forward on the seat tab,
located on the rear seatback,
to fold the seatback down.
To return the seatback to its original position, push it
back up and make sure it latches.
