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.
Your vehicle also has rear heated seats. See Heated
Seats
on page 1-8.
Reclining Seatbacks
The vertical power seat control described earlier allows
the seatback
to recline.
But don’t have a seatback reclined
if your vehicle is
moving. Sitting
in a
re nec losition when your ve :le
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.

3. Pull (push if you are exiting the third row with no
assistance) the seat forward until it stops.
If the seatback isn’t 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.
Heated Seats
A safety belt that is improperly routed, not
properly attached, or twisted won’t 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. The
buttons used to
control this feature are
located on the back of the
center console. The
engine must be running for
the heated seat feature
To heat the seat, press the button to cycle through the
temperature settings of high and low. Press the
button a third time to turn the seats
off. An Indicator
light will glow for each heat setting when the seats are
operating.
The heated rear seats will shut
off automatically when
the ignition is turned
off.
Be sure to return the seat to the passenger position
when finished. Pull forward and push rearward on the
seat to make sure it is locked in place.

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
n-’
do ---!Lh safety belts.
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.
It is extremeiy 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
Safety Belt Reminder
Light
on page 3-30.
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 Why Safety Belts Work
serious that even buckled up, a person wouldn't survive.
But most crashes are in between. In many of them, When you ride in or
on anything, you go as fast
people
who buckle up can survive and sometimes walk as it goes-
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!
Take the simplest vehicle. Suppose it's just a seat
on
wheels.
