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.” iii
Vehicle Damage Warnings You will also find notices in this manual. 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. The notice tells 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 which 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 specific component, control, message, gage, or indicator. iv
