How to Use this Manual
Many people read their owner’s manual from beginning
to end when they first receive their new vehicle. If you
do this, it will help you learn about the features and
controls for your vehicle. In this manual, you’ll find
that pictures and words work together to explain
things quickly.
Safety Warnings and Symbols
You will find a number of safety cautions in this book.
We use a box and the word CAUTION to tell you
about things that could hurt you if you were to ignore
the warning.
CAUTION:
These mean there is something that could hurt
you or other people.
In the caution area, we tell you what the hazard is. Then
we tell you what to do to help avoid or reduce the
hazard. Please read these cautions. If you don’t, you or
others could be hurt.

viii
You will also find a circle
with a slash through it in
this book. This safety
symbol means “Don’t,”
“Don’t do this” or “Don’t
let this happen.”
Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could
damage your vehicle.
In the notice area, we tell you about something that can
damage your vehicle. Many times, this damage would
not be covered by your warranty, and it could be costly.
But the notice will tell you what to do to help avoid
the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors or
in different words.
You’ll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.

Seats and Seat Controls
This section tells you about the seats -- how to adjust
them and fold them up and down. It also tells you about
reclining front seatbacks and head restraints.
Power Seats
You can adjust the front seats with the controls located
on the side of the seat, next to the door.
You can use the round center knob to move the seat to
where you want it. To do this, move the knob up. To
lower the seat, move the knob down. To move the seat
forward or rearward, move the knob toward the front of
the vehicle or toward the rear.
You can also raise and lower the front and rear of the
seat. To raise or lower the front of the seat, move the
front lever up or down. To raise or lower the rear of the
seat, move the rear lever up or down.

1-3
Power Lumbar Adjustment
Your vehicle has a power lumbar adjuster located at the
front of the control panel on the left side of the seat. You
can increase or decrease lumbar support in an area of the
lower seatback.
To increase support, press and hold the front of the
rocker switch. Let go of the switch when the lower
seatback reaches the desired level of support.
To decrease support, press and hold the rear of the
rocker switch. Let go of the switch when the lower
seatback reaches the desired level of support.
Heated Front Seats
The control for the driver’s side heated seat is located on
the left side of the seat. The control for the right front
passenger is located on the right side of the passenger
seat. Move the switch forward to MED or HIGH
temperature to turn on the heating elements in the seat.
The right front passenger’s safety belt must be buckled
before the heating elements in that seat will operate. To
turn the heated seats off, move the switch rearward to
OFF. For information on heated rear seats, see “Heated
Rear Seats” in the Index.

1-4
Reclining Front Seatbacks
To adjust the seatback,
move the lever rearward.
Release the lever to lock the seatback where you want it.
Move the lever again rearward and the seatback will go
to an upright position. But don’t have a seatback reclined if your vehicle
is moving.

1-5
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.
Pull firmly on the top of the head restraint to position it
to your liking.
Rear Seats
CAUTION:
If a head restraint is not installed on the seatback
or stored in the vehicle properly, it could be
thrown about the vehicle in a crash or sudden
maneuver. People in the vehicle could be injured.
Remove the head restraints only when you need
to fold the seat, and be sure that the head
restraints are stored securely in the appropriate
holes at the rear of the lower seat cushion. When
the seat is returned to the passenger position, be
sure the head restraints are installed properly.

1-6
Folding the Rear Seat
Your vehicle has a 60/40 rear seat. Either side may be
folded down to give you more cargo space.
Before folding, place the latch portion of the center
safety belt in the center armrest. That way, the center
safety belt will be out of the way when the seat is folded
and also will be easily available for passengers to use
when the seat is returned to the passenger position. Also,
make sure that nothing is under or in front of the seat.
When the seat is folded, it will lay flat on the floor.
To fold the seat, pull up on
the strap loop at the rear of
the seat cushion.
Then, pull the seat cushion up and fold it forward.
Fold the seatback forward
enough to allow removal
of the head restraints. Push
and hold the release buttons
at the bottom of each head
restraint height-adjust
post and slide the head
restraint out of the
height-adjust tubes.
Set the head restraints aside for now. You will stow
them in their proper position after you are done folding
the seat.
Pull the seatback forward and fold the seatback down
until it is flat.

1-7
Then, store the head
restraints by sliding them
into the rear of the seat
cushion. Make sure the
posts go in all the way.
To return the seat to the passenger position, use the
following procedure:
1. Remove the head restraints by sliding them out of
the seat cushion.
2. Lift the seatback up enough to install the
head restraints.
3. Push the seatback rearward all the way.
4. Lower the seat cushion until it latches in position.
5. Pull forward on the seatback and up on the seat
cushion to make sure that the seat is securely
in place.
If the latch plate portion of the center safety belt was put
in the center armrest when the seat was folded, take the
latch plate portion out and place it on the seat. That way,
the center position safety belt will be available for the
center rear seat passenger to use.

1-8
Heated Rear Seats
The controls for the heated
rear seats are located on the
rear of the center floor
console, below the rear seat
audio controls.
Press the top of the switch to HI or the bottom of the
switch to LO to turn on the heating elements in the
outside rear seat positions. The text HI or LO on the
switch will illuminate to indicate that the heated seat
elements are operating. The switch on the left side
operates the driver’s seat and the switch on the right side
operates the passenger’s sent. The rear seat outside
passenger’s safety belt must be attached before the
heating element in that seat will operate. To turn the
heated seats off, move the switch to the center. For more
information on heated front seats, see “Heated Front
Seats” in the Index.
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.
