Programming for automatic seat and mirror movement
can be done through the Driver Information Center
(DIC). You can choose to either select or not select
automatic seat and mirror movement by using the
remote keyless entry transmitter, by placing your
key in the ignition, or when exiting the vehicle. For
programming information, see ªVehicle Programming
and Personalization Featuresº in the Index.
Heated Front Seats (Option)
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 to cycle through
the temperature settings of high, medium and low, and
to turn the heated seat 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 vertical button with
the heated seatback symbol. An indicator light on the
seatback switch will glow to designate that only the
seatback is being heated. Additional presses will cycle
through the heat levels for the seatback only. Press the
horizontal button again to heat the whole seat.
The feature will shut off automatically when the ignition
is turned off.

1-5 Power Reclining Front Seatback
The vertical power seat control described earlier allows
the seatback to recline.
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.

1-6 Head Restraints
Slide the head restraint up or down 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.
On some models, the head restraints tilt forward and
rearward also.
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
Your vehicle has a folding rear seat which lets you fold
the seatbacks down for more cargo space.
Pull up on the tab 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.

1-7
The rear seatback handles
are located on the 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.
To return the head restraint to the upright position, reach
behind the seat and pull the restraint up until it locks
into place. Push and pull on the head restraint to make
sure that it is latched securely.

Safety Belts: They're for Everyone
This part of the manual tells you how to use safety belts
properly. It also tells you some things you should not do
with safety belts.
And it explains the air bag system.
CAUTION:
Don't let anyone ride where he or she can't wear
a safety belt properly. If you are in a crash and
you're not wearing a safety belt, your injuries
can be much worse. You can hit things inside the
vehicle or be ejected from it. You can be seriously
injured or killed. In the same crash, you might
not be if you are buckled up. Always fasten your
safety belt, and check that your passengers' belts
are fastened properly too.
CAUTION:
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision,
people riding in these areas are more likely to be
seriously injured or killed. Do not allow people to
ride in any area of your vehicle that is not
equipped with seats and safety belts. Be sure
everyone in your vehicle is in a seat and using a
safety belt properly.
Your vehicle has a light
that comes on as a reminder
to buckle up. See ªSafety
Belt Reminder Lightº in
the Index.

In most states and Canadian provinces, the law says to
wear safety belts. Here's why: They work.
You never know if you'll be in a crash. If you do have a
crash, you don't know if it will be a bad one.
A few crashes are mild, and some crashes can be so
serious that even buckled up a person wouldn't survive.
But most crashes are in between. In many of them,
people who buckle up can survive and sometimes walk
away. Without belts they could have been badly hurt
or killed.
After more than 30 years of safety belts in vehicles,
the facts are clear. In most crashes buckling up does
matter ... a lot!Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.
Take the simplest vehicle. Suppose it's just a seat
on wheels.

1-10
Put someone on it.Get it up to speed. Then stop the vehicle. The rider
doesn't stop.

1-11
The person keeps going until stopped by something.
In a real vehicle, it could be the windshield ...or the instrument panel ...
