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 nd 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.”
iii

Vehicle Damage Warnings
Also, in this manual you will nd 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 specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
