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, located on the sides of the front
seats, move and adjust the angle of the front seats.
D Moving the seat cushion control (A) forward or
rearward moves the entire seat.
D Moving the seat cushion control (A) up or down
adjusts the seat height.
D Lifting up or pressing down on the front part of the
seat control (A) adjusts the front angle of the
seat cushion.
D Lifting up or pressing down on the rear part of the
seat control (A) adjusts the rear angle of the
seat cushion.
D Lifting up or pressing down on the rear part of the
recline control (B) will also adjust the position of the
safety belt height adjuster.

1-3
Four-Way Power Lumbar Control
(If Equipped)
If your vehicle has this
feature, the driver’s and
passenger’s seatback lumbar
support can be adjusted four
ways by moving the single
switch located on the side of
the seat.
To increase the lumbar support, push the switch forward.
To decrease the support, push the switch backward. To
adjust the location of the lumbar support, push the
switch upward or downward.
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.
If you have the optional personalization package, the
power lumbar control can be programmed for memory
recall. For more information, see “Memory and
Personalization Features” in the Index.
Massaging Lumbar (If Equipped)
Push the top of the lumbar control 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 each front seat. With the ignition in ON, first use the
power seat control to get the proper position.
Then press the top of the control where it is marked
AUTO. The system will inflate the cushion and take a
reading, then automatically deflate the cushion to a
suggested level of comfort, by distributing the
pressure evenly.
You may still wish to further adjust the overall firmness
or softness of the seat cushion. To get to your desired
level of comfort, hold the control up to increase the
firmness, or down for less firmness. When you let go of
the control, the seat will then automatically readjust to
your desired level of comfort.
You will also need to adjust the lumbar support. To
increase the lumbar support, push forward on the control
and to decrease support, push rearward on the control.
(The lumbar will then automatically adjust to your
body’s positioning for the duration of the trip in
two-minute cycles.)
If you exit the vehicle after the system has been
activated and the seat is left unoccupied for more than
two minutes, the system will deflate. You will then need
to readjust the lumbar support upon returning to
your vehicle.
To turn off the adaptive seat feature while still in your
vehicle, press the control down briefly. The seat will
also deflate when the ignition is turned to 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
previous settings.
Adjust the driver’s seat (including the lumbar
adjustments), both the outside mirrors and steering
wheel to a comfortable position and then press the SET
button. Within five seconds, press button 1.
A second mirror, seating and steering wheel position can
be programmed by repeating the above steps and
pressing button 2. Each time a memory button is
pressed, a single beep will sound. Each time button 1 or
2 is pressed, the memory positions will be recalled. Two
personalized exit positions can be set by first recalling
the driving position (1 or 2), positioning the wheel and
seat in the desired exit positions and then pressing the
SET button and, within five seconds, pressing the EXIT
button. the exit position for either previously set driver
can be recalled by pressing the EXIT button.
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 directly to the numbers on the
buttons on the door panel and each seat and mirror can
be programmed to suit driver 1 or 2.
When the key is placed in the ignition in the OFF
position or when the unlock button is pressed on the
transmitter, the seats and mirrors will automatically
adjust to the programmed position.
Programming for automatic mirror and/or seat
movement is done through the Driver Information
Center (DIC). You can choose to either select or not
select automatic seat and/or mirror movement using the
transmitter or by placing your key in the ignition. For
programming information, see “Memory and
Personalization Features” in the Index.

1-6
Heated Seats (Option)
Your vehicle may be equipped with heated front and rear
seats. The control 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
shut off when the ignition is turned to OFF.
Reclining Front Seatbacks
Press the recliner control (B), located on the side of the
seat, forward or rearward to adjust the seatback.
Push the recliner control (B) up or down to adjust the
safety belt tower.

1-7
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.

1-8
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.
On some models, the head restraints tilt forward and
rear also.
Some rear seats have adjustable head restraints. Slide an
adjustable 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.
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.

1-9
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. (See “Safety Belt
Reminder Light” in
the Index.)
In most states and 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!
