Safety Warnings and Symbols
There are a number of safety cautions in this book. We
use a box and the word CAUTION to tell 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 do not,
you or others could be hurt.
You will also find a circle
with a slash through it in
this book. This safety
symbol means “Do Not,”
“Do Not do this” or “Do Not
let this happen.”
iii

Vehicle Damage Warnings
Also, in this manual you will find these notices:
Notice: These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell 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.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specific component, control, message,
gage, or indicator.
If you need help figuring out a specific name of a
component, gage, or indicator, reference the following
topics:
•Seats and Restraint Systems in Section 1
•Features and Controls in Section 2
•Instrument Panel Overview in Section 3
•Climate Controls in Section 3
•Warning Lights, Gages, and Indicators in Section 3
•Audio System(s) in Section 3
•Engine Compartment Overview in Section 5

Front Seats
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.
Vertical Control: You can use the vertical control to
adjust the angle of the seatback. Move the reclining
seatback forward or rearward by moving the top of the
control toward the front or toward the rear of the
vehicle.
For information on the reclining seatbacks, see Reclining
Seatbacks on page 1-5.
Your vehicle may have a memory function which allows
seat settings to be saved and recalled. See Memory
Seat on page 2-49 for more information.
1-2

Power Lumbar
Your vehicle’s seats may be equipped with power
lumbar.
You can increase or
decrease lumbar support
in an area of the lower
seatback with this control,
located on the outboard
sides of the front seat(s).
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.
Your vehicle may have a memory function which allows
seat settings to be saved and recalled. See Memory
Seat on page 2-49 for more information.
1-3

Heated Seats
If your vehicle has this
feature, the buttons are
located on the front doors.
The engine must be
running for the heated
seats to work.
To heat the entire seat, press the horizontal button with
the heated seat and seatback symbol. Press the
button to cycle through the temperature settings of high,
medium and low and to turn the heated seat off.
Indicator lights will be lit to designate the level of heat
selected: three for high, two for medium, and one
for low.
To heat only the seatback, press the vertical button with
the heated seatback symbol. An indicator light on the
seatback button will be lit 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 seats will be canceled after the ignition is
turned off. If you still want to use the heated seat feature
after you restart your vehicle, you will need to press
the heated seat button again.
1-4

Reclining Seatbacks
The front seats have a power recline feature. See
Power Seats on page 1-2 for more information on how
to operate them.
{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts cannot do their
job when you are reclined like this.
The shoulder belt cannot do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt cannot 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.
Do not have a seatback reclined if your vehicle is
moving.
1-5

Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.
Pull the head restraint up to raise it. Push the head
restraint down to lower it.
Each front head restraint can also be tilted forward to
four positions by pulling on it.
A click will sound after each tilt position is reached.
Pull the head restraint forward, past the last position, to
release it to the upright position.
The rear seat head restraints are also adjustable up and
down, but they do not tilt.
