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.
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.”

viii
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 power seats -- how to
adjust them, and also about the reclining front seatbacks,
memory seats, lumbar adjustments and heated seats.
Power Seats
The power seat controls
are located on the
outboard side of the
front seat cushions.
D Move the front of the seat control up or down to
adjust the front portion of the cushion.
D Move the rear of the seat control up or down to
adjust the rear portion of the cushion.
D Lift up or push down on the center of the seat control
to move the entire seat up or down.
D To move the seat forward or rearward, slide the seat
control forward or rearward.
Four Way Power Lumbar Control
(If Equipped)
If you have this feature, the
driver’s and passenger’s
seatback lumbar support
can be adjusted four ways
by moving a single switch
located on the outboard side
of the seat.
To increase or decrease support, hold the switch forward
or rearward. To move the lumbar up or down, hold the
switch up or down.
Keep in mind that as your seating position changes, as it
may during long trips, so should the position of your
lumbar support. Adjust the seat as needed.

1-3
Massaging Lumbar (If Equipped)
Push the top of the lumbar
control located on the
outboard side of the seat
where it is marked AUTO
briefly to activate the
massage feature.
The massage cycle will run continuously for up to
10 minutes and can be interrupted by pushing the
lumbar control down briefly. The lumbar support can
be adjusted during the massage cycle by moving the
switch forward to increase support and rearward to
decrease support. The massage cycle will continue
to run even if the ignition is turned to OFF,
unless interrupted.
Four-Way Rear Power Lumbar
(If Equipped)
Four-way lumbar, without
the massage feature, is also
available for the outboard
rear seating positions.
To activate the rear lumbar feature, push forward on the
switch located on the rear door trim to increase support
or rearward to decrease support. The lumbar switch can
also be moved up and down to adjust the location of
the support.

1-4
Adaptive Seat Control (Option)
The adaptive seat control is
located on the outboard side
of the driver’s seat. Use the
power seat control first to
get the proper position.
When the ignition is turned to ON, press the top of
the power lumbar control where it is marked AUTO to
activate the adaptive feature. The seatback and cushion
will inflate to adjust to the driver’s body positioning in
four-minute cycles.
To reshape the lower seatback, press the lumbar
control forward to increase support and rearward to
decrease support.
To turn off the adaptive seat feature, press the control
down. The seat will deflate when the adaptive seat
control or the ignition is turned off.

1-5
Memory Seat, Mirrors and Steering
Wheel (Option)
The controls for these
features are located on the
driver’s door panel, and are
used to program and recall
memory settings for the
driver’s seating positions.
Adjust the driver’s seat (including the seatback recliner,
lumbar and shoulder belt height adjustments), both the
outside mirrors and steering wheel to a comfortable
position and then press the MEMORY SET button.
Within five seconds, press button “1” (for driver 1).
A second mirror, seating and steering wheel position
can be programmed by repeating the above steps and
pressing button “2” (for driver 2). Each time a memory
button is pressed, a single beep will sound. Each time
button 1 or 2 is pressed and released while the vehicle
is in PARK (P), the memory positions will be recalled.
Each time button 1 or 2 is pressed and held while the
vehicle is out of PARK (P), the memory positions will
be recalled.
To stop recall movement of the memory seat and
steering wheel at any time, press one of the power seat,
steering wheel or mirror controls.
Two personalized exit positions can be set by first
recalling the driving position (by pressing 1 or 2),
then positioning the steering wheel and seat in the
desired exit positions and then pressing and releasing
the MEMORY SET button and, within five seconds,
pressing the EXIT button. With the vehicle in PARK (P),
the exit position for either previously set driver can be
recalled by pressing the EXIT button. The mirrors,
power lumbar and shoulder belt height positions will
not be stored or recalled for the exit positions.

1-6
If you use the remote keyless entry transmitter to enter
your vehicle, automatic seat and mirror movement will
occur. The numbers on the back of the transmitters,
1 and 2, correspond to the numbers on the buttons
on the door panel.
When the key is placed in the ignition in OFF or when
the unlock button is pressed on the remote keyless entry
transmitter, the seats and mirrors will automatically
adjust to the programmed position.
Programming for automatic seat, steering wheel and
mirror movement is done through the Driver Information
Center (DIC). You can choose to either select or not
select automatic seat and mirror movement using the
remote keyless entry transmitter, placing your key in
the ignition, or by exiting the vehicle. For programming
information, see “Vehicle Programming and
Personalization Features” in the Index.
Heated Seats (If Equipped)

1-7
Your vehicle may have heated front and rear seats. The
buttons are located on the armrests. The HEAT/OFF
button controls the temperature settings HI, MED
and LO. The other button is to choose BACK ONLY
heating. The LO setting warms the seatback and cushion
until the seat approximates body temperature. The MED
and HI settings heat the seatback and seat cushion to a
slightly higher temperature, and the BACK ONLY heats
only the seatback. The temperature can be adjusted
by pushing the button from HI to LO or, until the
desired setting is reached. You will be able to feel heat
in approximately two minutes. To heat just the seatback,
push the BACK ONLY button once, after first activating
the heated seat feature. To turn off the heat in the
seatback, push the button again. The feature will
also shut off when the ignition is turned to OFF.
Reclining Front Seatbacks
Press the recliner control
located on the outboard
side of the seat, forward
or rearward to adjust
the seatback.
Push the recliner control up or down to adjust the
shoulder belt height. See “Shoulder Belt Height
Adjuster” in the Index for more information.

1-8
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.
