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
Horizontal Control: You can adjust your vehicle’s front
seats with the horizontal control located on the outboard
edge of each front seat.
Raise or lower the front of the seat by raising or
lowering the forward edge of the control. Raise or lower
the rear of the seat by raising or lowering the rear edge
of the control.
Move the seat forward or rearward by moving the
whole control toward the front or toward the rear of
the vehicle.
Moving the whole control up or down raises or lowers
the entire seat cushion.

1-3
Power Lumbar Control
You can increase or
decrease lumbar support
in an area of the
lower seatback.
To increase support, press
and hold the front of the
control. To decrease
support, press and hold
the rear of the control.
Let go of the control when the lower seatback reaches
the desired level of support.
You can also reshape the side wing area of the lower
seatback for more lateral support.
To increase support, press and hold the top of the
control. To decrease support, press and hold the bottom
of the control. Let go of the control when the lower
seatback reaches the desired level of support.
Memory Seat
The controls for the
memory seat are located on
the driver’s door trim panel.
The memory function can recall preset positions for the
driver’s seat cushion and the recliner. The memory function
does not store the lumbar or back support positions.
To set your memory seat do the following:
1. Adjust the driver’s seat to the desired position.
2. Press the SET button and then press the “1” or “2”
button of the memory control within five seconds.
When your vehicle is in PARK (P), press the same
button of the memory control to recall the seat setting.
To do the same thing for a second driver, follow the
preceding steps, but press the other number button of
the memory control. The memory feature only works
when the transmission is in PARK (P).

1-4
Heated Front Seats
The control for the driver’s
side heated seat is located
on the driver’s side door
panel. The control for the
passenger’s side heated seat
is located on the passenger’s
side door panel.
The ignition must be in RUN for this feature to operate.
To activate the heated seats, press the button once for the
HI heat setting. Press the button again for the LO heat
setting. To turn off the heated seats, press the button a third
time. An indicator light on the button will illuminate for
each heat setting anytime the heated seats are operating.
The heated front seats will be canceled after the ignition
is turned to OFF. If you still want to use the heated front
seat feature after you restart your vehicle, you will need
to press the heated seat button again.
You vehicle also has rear heated seats. See the section
on “Rear Heated Seats” later in this section for
more information.
Reclining Front Seatbacks
Your vehicles front seatbacks have a recline feature.
Vertical Control: You can use the vertical control to
adjust the angle of the seatback. Move the reclining front
seatback rearward or forward by moving the control
toward the rear or toward the front of the vehicle.

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.

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 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.
The rear seat head restraints in your vehicle are adjustable.
They work the same as the front seat head restraints.
Rear Seats
60/40 Split Bench Seat (Second Row)
If your vehicle has a 60/40 split bench, the seatbacks can
be reclined and the seats can be folded to give you more
cargo space.
Reclining the 60/40 Split Bench Seatbacks
To recline the seatback, do the following:
1. Pull the lever located at
the base of the seat
cushion forward.
2. Release the lever to lock the seatback where you
want it. Pull the lever again without pushing on
the seatback and the seatback will go to an
upright position.

1-7
Folding the 60/40 Split Bench Seatbacks
The rear seat may have a 60/40 split seat which may be
folded down to create a load floor and give you more
cargo space. The rear seatbacks are equipped with
rearward folding head restraints. When the seatback is
being folded down, the head restraint will automatically
fold rearward to allow a flat load floor for cargo or entry
to the third row seat.
To fold the rear seat, do the following:
1. Insert the two safety belt buckles into the pocket in
the seatback before folding the rear seat on the
driver’s side.
That way, the buckles will be out of the way when
the seat is folded and will be 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.
2. Make sure the seatback is in an upright position
(unreclined) before folding it.
3. Pull up on the strap loop
located at the rear of the
seat cushion and pull the
seat cushion up. Then
fold it forward.
4. Pull the seatback forward and fold it down until it
is flat.
