have all of them. For example, more than one
entertainment system may be offered or your
vehicle may have been ordered without a front
passenger or rear seats.
Keep this manual in the vehicle, so it will be there
if it is ever needed. If the vehicle is sold, leave

How to Use This Manual
Many people read the owner manual from
beginning to end when they first receive their new
vehicle. If this is done, it can help you learn
about the features and controls for the vehicle.
Pictures and words work together in the
owner manual to explain things.
If your vehicle has the DURAMAX
®
Diesel engine,
refer to the DURAMAX
®
Diesel supplement for
additional and specific information on this engine.
Index
A good place to quickly locate information about
the vehicle is the Index in the back of the manual.
It is an alphabetical list of what is in the manual
and the page number where it can be found.
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.”

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
