feature to work.

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
to heat the whole seat.
The heated front seats will shut off automatically when
the ignition is turned off.Reclining Seatbacks

Release the lever to lock the seatback where you want
it. Lift the lever without pushing on the seatback and
the seatback will go to an upright position.

on how to operate the reclining seatback feature.
1-5

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.
The rear seat head restraints in your vehicle are
adjustable. They work the same as the front seat head
restraints.
Rear Seats
Rear Seat Operation
The rear seat is a 60/40 split rear seat that can be
folded to give you more cargo space and access to the
folding midgate. SeeMidgate on page 2-14for more
information on operation of the folding midgate.
To fold either side of the seat do the following:
1. Push the rear head restraints all the way down.
2. Pull the seat loop
located where the
seatback and
seat cushion meet.
The seat cushion will
release and allow
you to tilt it toward the
front of the vehicle.
1-7

3. Grasp the seatback and pull it toward the front of
the vehicle. Push it down until it is at. You may
have to move the front seats forward slightly to
do this.
4. Repeat the procedure for the other side.
To return the seats to the normal position, pull the
seatback up and fold the seat cushion down.
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it is
locked.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted will not provide
the protection needed in a crash. The person
wearing the belt could be seriously injured.
After raising the rear seatback, always check
to be sure that the safety belts are properly
routed and attached, and are not twisted.

Safety Belts
Safety Belts: They Are 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.
{CAUTION:
Do not let anyone ride where he or she can not
wear a safety belt properly. If you are in a
crash and you are 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.
SeeSafety Belt Reminder
Light on page 3-36.

In most states and in all 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.
