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.
If your vehicle is a Two-mode Hybrid, see the
Two-mode Hybrid manual for more information.
Index
To quickly locate information about the vehicle use 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.
Cautions tell what the hazard is and what to do to avoid
or reduce the hazard. Read these cautions.
A circle with a slash
through it is a safety

“Do Not,” “Do Not do
this” or “Do Not let
this happen.”

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