GM Service Manual Online
For 1990-2009 cars only

Before operating the navigation system, read this manual to become familiar with its operation.

While entering the vehicle or when turning the vehicle off, some DVD Map Disc noise is normal.

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.

The navigation system includes navigation and audio functions.

While the vehicle is parked:

    • Familiarize yourself with all of its controls.
    • Familiarize yourself with its operation.
    • Set up your audio by presetting your favorite stations, setting the tone, and adjusting the speakers.
    • Set up the navigation features that can only be done before you begin driving.

A destination or alphanumeric text can only be entered when the vehicle is in PARK (P). The touch-sensitive screen buttons leading to the alphanumeric keyboard are not lit while driving.

Other functions may also not function while driving. They appear grayed out on the screen. 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 lets you:

    • Plan a route with provided turn-by-turn route and map guidance with voice prompts.
    • Select a destination using various methods and choices.

Always be alert and obey traffic and roadway laws and instructions, regardless of the guidance from the navigation system. The navigation system uses street map information that does not include all traffic restrictions or the latest road changes, it may suggest using a road that is now closed for construction or a turn that is prohibited by signs at the intersection. The system uses limited information. Always evaluate whether following the system's directions is safe and legal for the current conditions.
