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.

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:

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.

through it is a safety
symbol which means
“Do Not,” “Do Not do
this” or “Do Not let this

{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.
CAUTION: (Continued)
CAUTION: (Continued)
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.
