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.
Front Seatback Latches
(Two-Door Models)
The front seatback folds forward to let people get into the
back seat.
Your seatback will move .back and forth freely, unless you
come to a sudden stop. Then it will lock in place.
There's one time the seatback may not fold without some
help from you. That's if your vehicle is parked facing
down a fairly steep hill.
To fold a front seatback
forward, push the seatback
toward the rear as you lift
this latch. Then the
seatback will fold forward.
The latch must be down for
the seat to work properly.
