Heated Seats
Your vehicle may have
heated front seats. The
buttons used to control this
feature are located on the
front doors. The engine
must be running for the
heated seat feature
to work.
To heat the entire seat, press the horizontal button with
the heated seat symbol. Press the button to cycle
through the temperature settings of high, medium and
low and to turn the heated seat off. Indicator lights
will glow to designate the level of heat selected,
three for high, two for medium, and one for low.The low setting warms the seatback and cushion until
the seat temperature is near body temperature. The
medium and high settings heat the seatback and seat
cushion to a slightly higher temperature. You will be able
to feel heat in about two minutes.
To heat only the seatback, press the vertical button with
the heated seatback symbol. An indicator light on the
seatback button will glow to designate that only the
seatback is being heated. Additional presses of
the seatback button will cycle through the heat levels for
the seatback only. Press the horizontal button again

Reclining Seatbacks
Your vehicle’s front seatbacks have a recline feature
which is described earlier. SeePower Seats on
page 1-2.
But don’t have a seatback reclined if your vehicle is
moving.{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts can’t do their job
when you’re reclined like this.
The shoulder belt can’t do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt can’t do its job either. In a crash
the belt could go up over your abdomen. The
belt forces would be there, not at your pelvic
bones. This could cause serious internal
injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety belt
properly.

Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.Pull straight up on the head restraint to raise it and
push it down to lower it.
The front head restraints can also be tilted forward in
addition to being slid up or down. To tilt either of
the front head restraints do the following:
Pull the head restraint toward you until you hear a click.
Then let go. The head restraint will stay in this position
unless you pull it forward more until another click is
heard. There are four positions available: initial position,
rst click, second click, and third click. After the third
position (three clicks) is reached, pulling the head
restraint farther will release it back to the normal upright
position.
The rear head restraints can be slid up or down just as
the front head restraints, but they do not tilt.
