Canadian Owners A French language copy of this manual can be obtained from your dealer or from: Helm, Incorporated P.O. Box 07130 Detroit, MI 48207 How to Use This Manual Many people read the owner manual from beginning to end when they first receive their new vehicle. If this is done, it can help you learn about the features and controls for the vehicle. Pictures and words work together in the owner manual 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. Litho in U.S.A. Part No. 05H2A First Edition ii © Copyright General Motors Corporation 04/19/04 All Rights Reserved 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. You will also find 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." {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. iii Vehicle Damage Warnings Also, in this manual you will find 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 specific component, control, message, gage, or indicator.

See Memory Seat on page 2-63 for more information. 1-2 Power Lumbar Your vehicle's seats have power lumbar.
