Using this Manual
Many people read the owner manual from beginning to
end when they rst receive their new vehicle to learn
about the vehicle’s features and controls. Pictures
and words work together to explain things.
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.
A box with the word CAUTION is used to tell about
things that could hurt you or others if you were to ignore
the warning.
{CAUTION:
These mean there is something that could hurt
you or other people.
We tell you what the hazard is and what to do to help
avoid or reduce the hazard. Please read these cautions.
If you do not, you or others could be hurt.
A circle with a slash
through it is a safety
symbol which means
“Do Not,” “Do Not do
this” or “Do Not let this
happen.”

Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the

by your vehicle’s warranty, and it could be costly.
The notice tells what to do to help avoid the damage.

CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle which
use the same words, CAUTION or NOTICE.
