is not moving.
Pull up on the lever located under the front of the
manual seat
to unlock it. Slide the seat to where you
want it and release the lever. Then try

ManualLumbar
Your vehicle may have this feature. This control is
located on the outboard side of
the seat.
Turn the knob counterclockwiseto increase lumbar
support and clockwise to decrease lumbar support.
Power Lumbar
Your vehicle may have this feature. The driver’s and
passenger’s seatback lumbar support can be adjusted
by moving a single control located on the outboard
side of the seat cushions.
To increase or decrease support, hold the control
forward or rearward.
Keep in mind that as your seating position changes,
as it may during long trips, so should the position of your
lumbar support. Adjust the seat as needed.
Heated Seats
7
Your vehicle may have
heated front seats. The
buttons used
to control this
feature are located on
the front door armrests.
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 repeatedly
to cycle through the temperature settings of high,
medium, low and
off. The 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 button with the
words “BACK
ONLY’. An indicator light on the seatback
switch will glow to designate that only the seatback is
being heated. Additional presses will cycle through

power seat control described earlier allows the seatback
to recline.
But don’t have a seatback reclined
if your vehicle is
moving.

Head Restraints
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 wouldbe 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 theseat and wear your safety belt
properly. 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.
The head restraints lock into place when raised.
To release the head restraint and lower it, press the
tab located on the top of the seatback.

Rear Seats
Rear Seat Operation
Your vehicle may have a folding rear seat which lets
you fold the seatbacks down for more cargo space.
The rear seatback handles

outboard side of the rear
seatbacks.
---.=_-
Pull the seatback toward you as you lift up on the
handle. The head restraint will automatically fold out of
the way when the seatback is folded down.
To raise the seatbacks, lift up the seatbacks and push
on them until they lock into the upright position.
Push and pull on the seatbacks to make sure that they
are latched securely. Then fold the bottom seat
cushion back into place.
Pull up on the loop located where the seat cushion
meets the seatback to fold the seat cushion up and out
of the way. This will allow the seatback to
fold flat
and increase the cargo area.

You can be seriously injured or killed. In the

Questions and Answers About
Safety Belts
Q: Won’t I be trapped in the vehicle after an
accident if I’m wearing a safety belt?
A: You could be - whether you’re wearing a safety
belt or not. But you can unbuckle a safety belt,
even
if you’re upside down. And your chance
of being conscious during and after an accident,
so you can unbuckle and get out, is much greater if
you are belted.
or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That’s why
safety belts make such good sense.
Q: If my vehicle has air bags, why should I have to
wear safety belts?
A: Air bags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only;
so they work with
safety belts - not instead of them. Every air bag
system ever offered for sale has required the use of
safety belts. Even if you’re in a vehicle that has
air bags, you still have to buckle up
to get the most
protection. That’s true not only in frontal collisions,
but especially in side and other collisions.
