The navigation system's voice recognition allows for hands-free operation of the navigation system, audio system, and OnStar® features. The DVD map disc must be installed in the navigation system for voice recognition to work. See "Installing the DVD Map Disc" under Maps for more information.

Voice recognition can be used when the ignition is on or when Retained Accessory Power (RAP) is active. See "Retained Accessory Power (RAP)" in the Index of your vehicle's owner manual for more information.

To use voice recognition, do the following:


  1. Object Number: 2000431  Size: A3

    Push and hold the SRCE button on the steering wheel until you hear a beep. The audio system mutes.

  2. Clearly state one of the commands listed on the following pages.

Helpful Hints for Stating Commands

    • When a multiple command is available, choose the command that works best.
    • Words that are in brackets are optional. For example, for the command Radio [band] [select] FM, stating Radio FM or Radio select FM are both valid commands.
    • When the system recognizes the command the system does one of the following:
       - Perform the function.
       - Ask you to confirm your choice.
       - Issue an error message "Did not recognize. Voice Recognition Canceled."
    • If you experience difficulty with the system recognizing a command, try saying it more softly, and wait for a few seconds after the beep, or repeat the command.
    • Background noise may cause voice commands to be misunderstood, including airflow noise from wind.
    • To use the voice recognition system, the map DVD must be loaded and the navigation system must be on.

This system is able to recognize commands in three different languages. The system only recognizes commands based on the language selected from the Driver Information Center (DIC). See DIC Vehicle Customization for more information.
