GM Service Manual Online
For 1990-2009 cars only

Caution: 

If the HUD image is too bright or too high in your field of view, it may take you more time to see things you need to see when it is dark outside. Be sure to keep the HUD image dim and placed low in your field of view.

If the vehicle has the Head-Up Display (HUD), some information concerning the operation of the vehicle is projected onto the windshield. This includes the speedometer reading, transaxle positions, compass direction, outside air temperature, the tap shift gear and the upshift symbol if active, and a brief display of the current radio station, including XM information or CD track. It will also display turn-by-turn guidance information if the vehicle is has a navigation radio. The images are projected by the HUD lens located on the driver's side of the instrument panel.

The tap shift gear and the upshift symbol will also appear on the HUD if the vehicle has tap shift and it is active.

The HUD information can be displayed in one of three languages, English, French, or Spanish. The speedometer reading and other numerical values can be displayed in either English or metric units.

The language selection and the units of measurement are changed through the trip computer in the Driver Information Center (DIC). See "Options" under DIC Controls and Displays .


Object Number: 1198030  Size: B3

The HUD information appears as an image focused out toward the front of the vehicle.

When the ignition key is turned to RUN, the HUD will display an introductory message for a short time, until the HUD has warmed up.

The following indicator lights come on the instrument panel when activated and will also appear on the HUD:

    • Turn Signal Indicators
    • High-Beam Indicator Symbol

The HUD will temporarily display CHECK TRIP COMPUTER when there are messages on the DIC trip computer.

The HUD will also display the following messages when these systems, if the vehicle has them, are active:

    • TRACTION CONTROL ACTIVE
    • STABILITY CONTROL ACTIVE

The HUD will temporarily display the TRACTION CONTROL OFF message when the traction control system is turned off.

The HUD will temporarily display the CRUISE SET message when cruise control is activated or cruise speed is increased.

Notice: If you try to use the HUD image as a parking aid, you may misjudge the distance and damage your vehicle. Do not use the HUD image as a parking aid.

When the HUD is on, the speedometer reading will continually be displayed. The current radio station or CD track number will display for a short period of time after the radio or CD track status changes. This will happen whenever one of the radio controls is pressed.

The speedometer size will be reduced when radio, CD information, warnings, or turn-by-turn guidance information are displayed on the HUD.

The HUD control is located on the console.

To adjust the HUD image so that items are properly displayed, do the following:

  1. Adjust the driver's seat to a comfortable position.
  2. Start the engine.
  3. Adjust the HUD controls.

Use the following settings to adjust the HUD.

(Off): Turn the outer ring on the HUD control to this position to turn the HUD off .

I II III IIII (Brightness) : Turn the outer ring on the HUD control clockwise to dim the display and counterclockwise to brighten it.

(Up) : Press this portion of the switch on the HUD control to move the image up.

(Down) : Press this portion of the switch on the HUD control to move the image down. Move the image as low as possible on the windshield, keeping it in full view.

(Page) : Press this button to select the display formats. Release the page button when the format number with the desired display is shown on the HUD.

    • Format One : This display gives the speedometer reading (in English or metric units), transaxle positions, compass direction, and the outside air temperature.
    • Format Two : This display includes the information in Format One without the compass direction and the outside air temperature.
    • Format Three : This display includes all the information in Format One, but turns the instrument cluster lighting off. Format three is only available at night.

All formats will show the turn-by-turn guidance information. It will display the next turn, direction, street name, and distance to the selected destination. When you near your destination, the HUD will display a distance bar that will fill in the closer you get to your destination. All navigation information is provided to the HUD by the navigation radio, if the vehicle has one.

The warning indicators still appear on the instrument panel when required. The HUD will display Stealth Mode On.

The HUD will store the last display format selected. If the last format displayed was Format One or Format Three, then Format One will be displayed when the vehicle is started.

If the last format was Format Two, then Format Two will be displayed.

The HUD image displayed on the windshield will automatically dim and brighten to compensate for outside lighting.

The HUD image can temporarily light up depending on the angle and position of the sunlight on the HUD display. This is normal and will change when the angle of the sunlight on the HUD display changes.

Polarized sunglasses could make the HUD image harder to see.

Care of the HUD

Clean the inside of the windshield as needed to remove any dirt or film that could reduce the sharpness or clarity of the HUD image.

To clean the HUD lens, use a soft, clean cloth that has household glass cleaner sprayed on it. Wipe the HUD lens gently, then dry it. Do not spray cleaner directly on the lens because the cleaner could leak into the unit.

If You Cannot See the HUD Image When the Ignition Is On

    • Is anything covering the HUD lens?
    • Is the HUD dimmer setting bright enough?
    • Is the HUD image adjusted to the proper height?
    • Are you wearing polarized sunglasses?
    • Still no HUD image? Check the fuse in the instrument panel fuse block. See Instrument Panel Fuse Block .

If the HUD Image Is Not Clear

    • Is the HUD image too bright?
    • Are the windshield and HUD lens clean?

If the HUD image is not correct, contact your dealer.

Keep in mind that the windshield is part of the HUD system. See Windshield Replacement .
