UNLOCK button within five seconds of
programming the memory button. You will hear a
chime to confirm programming of the transmitter.
When your vehicle is in PARK (P), push and release the

adjust the seat.
Pressing any of the seat adjuster switches, the SET
button or pressing the desired memory button twice will
cause the seat to stop moving. If you push the numbered
button to adjust the seat and start the vehicle while the
seat is still adjusting, adjustment will pause while the
ignition is in START. Adjustment will resume after the
ignition is in RUN.Heated Front Seats

the side of the seat. This

lower cushion and lower
back of the driver and
front passenger seats for
added comfort.
Press the lower part of the switch to turn the heater on
low. Press the upper part of the switch to turn the heater
on high. Put the switch in the center position to turn the
heater off.

1-5 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 because it
won't be against your body. Instead, it will be in
front of you. 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
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.
The head restraints tilt forward and rearward also.

1-6 Rear Seats
Your vehicle has a folding rear seat which lets you fold
the seatbacks down for more cargo space.
The rear seat release handles are on the rear of the
seatbacks. Push back on the seatbacks as you pull up on
the handles. The head restraint will automatically fold
out of the way when the seatback is folded down.
To raise the seatbacks, just lift up the seatbacks and push
until they lock in the upright position. Push and pull
on the seatbacks to check that the latches have locked
in the upright position. If they haven't, have them
fixed immediately.
To return the head restraints to the upright position,
reach behind the seats and pull the head restraint up until
it locks into position.
Push and pull on the head restraints to check that they
have locked in the upright position. If they haven't, have
them fixed immediately.
The rear seat head restraints are adjustable.
Push the button located under the head restraint to raise or
lower it. Slide the adjustable head restraint up or down so
that the top of the head restraint is closest to the top of
your ears. After releasing the button, push and pull on the
head restraint to make sure it's locked in place.

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.
