GM Service Manual Online
For 1990-2009 cars only

Before you begin to operate the navigation system, read this manual thoroughly to become familiar with it and to understand how the system works.

Keeping your mind on the drive is important for safe driving. See "Defensive Driving" in the Index of your vehicle's owner manual for more information. Get familiar with your vehicle's navigation system so you can use it with less effort and take full advantage of its features. Your navigation system includes not only navigation, but also audio functions. While your vehicle is parked:

    • Familiarize yourself with all of its controls: hard keys on the faceplate and touch-sensitive screen buttons.
    • Familiarize yourself with its operation.
    • Set up your audio by presetting your favorite stations, setting the tone, and adjusting the speakers. Then, when driving conditions permit, you can tune to your favorite stations using the presets and steering wheel controls (if equipped).
    • Set up the navigation features that can only be done before you begin driving, such as entering an address or a preset destination.

Entering a destination or alphanumeric text requires many steps, so you can only perform these operations when the vehicle is in PARK (P). You will notice that touch-sensitive screen buttons leading to the alphanumeric keyboard are dimmed out while driving.

Other functions may also be locked out while driving and they too will appear grayed out on the screen -- but all functions are available when parked. Some functions can be performed while driving, as long as you can do so without diverting too much of your attention from your driving.

Caution: This system provides you with a far greater access to audio stations and song listings. Giving extended attention to entertainment tasks while driving can cause a crash and you or others can be injured or killed. Always keep your eyes on the road and your mind on the drive -- avoid engaging in extended searching while driving.

Caution: Looking at the moving map on the navigation screen frequently or for too long while driving can cause a crash and you or others can be injured or killed. Keep your eyes and mind on the road and avoid looking too long or too often at the moving map on the navigation screen. Use the voice guidance directions whenever possible.

The navigation system allows you to do the following:

    • Plan a route with provided turn-by-turn route and map guidance with voice prompts.
    • Select a destination using various methods and choices.
    • Receive broadcast announcements on traffic and emergency alert communications.

The information in the system may not always be complete. Road conditions such as prohibited turns, detours, and construction zones, change frequently. It is important to consider whether you can follow the directions given by the system for the current conditions.
