How to Use This Manual
Many people read their owner’s manual from beginning
to end when they rst 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 will nd
that pictures and words work together to explain things.
Index
A good place to look for what you need is the Index in
back of the manual. It is an alphabetical list of what is in
the manual, and the page number where you will nd it.

Safety Warnings and Symbols
You will nd 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 nd 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.”
iii

Vehicle Damage Warnings
Also, in this book you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will 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.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specic component, control,
message, gage or indicator.
