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

These are some examples of symbols that may be found on the vehicle:

Section 1 Seats and Restraint Systems
1-1

Front Seats
Power Seats
The power seat controls are located on the outboard
edge of the front seats.
Horizontal Control: This control adjusts the
seat cushion.
•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.
•Lower or raise the entire seat cushion by moving
the whole control up or down.
Vertical Control: This control adjusts the seatback.
Move the reclining front seatback rearward or forward by
moving the control toward the rear or toward the front
of the vehicle. This adjusts the angle of the seatback.
For more information on the reclining seatbacks,
see Reclining Seatbacks on page 1-4.
Your vehicle has a memory function which allows seat
settings to be saved and recalled. See Memory Seat
on page 2-63 for more information.
1-2

Power Lumbar
Your vehicle’s seats have 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 2-63 for more information.
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.
1-3

Reclining Seatbacks
The front seats have a recline feature which is described
earlier. See Power Seats on page 1-2.{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.
1-4

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.
1-5

Rear Seats
Heated Seats
If your vehicle has this
feature, the buttons used
to control this feature
are located on the back of
the center console. The
engine must be running for
the heated seat feature
to work.
To heat the seat cushion, press the button to cycle
through the temperature settings of high and low. Press
the button a third time to turn the feature off. An
indicator light will glow for each heat setting when the
feature is operating.
The heated rear seats will shut off automatically when
the ignition is turned off.
60/40 Split Bench Seat
The 60/40 split bench seats can be folded to give you
more cargo space.
Folding the Seatbacks
The seatbacks (SUV only) are equipped with rearward
folding head restraints. When the seatback is being
folded down, the head restraint will automatically
fold rearward.
To fold the rear seat, do the following:
1. Make sure that nothing is under or in front of
the seat. 2. Pull up on the strap
loop located at the rear
of the seat cushion
and pull the seat
cushion up and fold
it forward.
3. Pull the seatback forward and fold it down until it
is flat.
If the seatback cannot fold flat because it interferes
with the cushion, try moving the front seat forward
and/or bringing the front seatback more upright.
4. Repeat the steps for the other half of the 60/40 split
bench seat.

Safety Belts
Safety Belts: They Are 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.
{CAUTION:
Do not let anyone ride where he or she cannot
wear a safety belt properly. If you are in a
crash and you are 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.
{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.
