How to Use this Manual Many people read their owner's manual from beginning to end when they first receive their new vehicle. If you do this, it will help you learn about the features and controls for your vehicle. In this manual, you'll find that pictures and words work together to explain things quickly. vii You will also find a circle with a slash through it in this book. This safety symbol means "Don't," "Don't do this" or "Don't let this happen." When you read other manuals, you might see CAUTION and NOTICE warnings in different colors or in different words. You'll also see warning labels on your vehicle. They use the same words, CAUTION or NOTICE. Vehicle Symbols Your vehicle may be equipped with components and labels that use symbols instead of text. Symbols, used on your vehicle, are shown along with the text describing the operation or information relating to a specific component, control, message, gage or indicator. If you need help figuring out a specific name of a component, gage or indicator reference the following topics in the index: Vehicle Damage Warnings Also, in this book you will find these notices: NOTICE: These mean there is something that could damage your vehicle. In the notice area, we tell you about something that can damage your vehicle. Many times, this damage would not be covered by your warranty, and it could be costly.

If you use the unlock button on the remote keyless entry transmitter to enter your vehicle, the preset driver's seat and mirror positions will be recalled if programmed to do so through the Driver Information Center (DIC). The numbers on the back of the transmitters, 1 or 2, correspond to the numbers on the memory controls. The seat and mirror positions can also be recalled by placing the key in the ignition if programmed to do so through the Driver Information Center (DIC). To stop recall movement of the memory feature at any time, press one of the power seat controls or memory buttons.
