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 your vehicle is equipped with the Head-Up Display (HUD), you can see some of the driver information that appears on your instrument panel cluster.

The information may be displayed in English or metric units and appears as an image focused out toward the front of your vehicle. The HUD consists of the following information:

    • Speedometer
    • Turn Signal Indicators
    • High-Beam Indicator Symbol
    • Tachometer
    • Oil and Temperature Gages
    • Shift Light (Performance SHIFT Light)
        This light is used for performance driving to indicate that the vehicle's best performance level has been reached to shift the transmission into the next higher gear. The SHIFT light will display at an engine speed of about 6,250 rpm, just prior to reaching the engine fuel cut-off mode.
    • Check Gages Warning
    • Engine Coolant Temperature Gage
    • Transmission Oil Temperature Gage
    • Engine Oil Temperature Gage
    • Engine Oil Pressure Gage
    • G-Force Gage
    • Audio Functions, Street Mode Only
    • Navigation, Only with Navigation Radio, Street Mode Only
    • Check Gages Warning

There are three HUD modes that you can choose to view in the HUD display. By pressing the MODE button, you can scroll through these modes in the following order:


Object Number: 1462835  Size: A1

Street Mode supports audio and navigation functions with your choice of tachometer settings.


Object Number: 1462848  Size: A1

Track Mode 1 supports the G-Force gage and minor gages with a circular tachometer.


Object Number: 1462851  Size: A1

Track Mode 2 supports G-Force gages and minor gages with a linear tachometer.

When you have chosen the desired HUD display, release the MODE button.

Within each mode, the display, can be further customized by pressing the PAGE button. Pressing this button in each mode will turn off and on the following:

    • Street Mode -- No tachometer, circular tachometer and linear tachometer.
    • Track Modes 1 and 2 -- No minor gage, coolant temperature, transmission oil temperature, engine oil temperature and engine oil pressure.

If your vehicle is equipped with a navigation radio, many of the turn-by-turn navigation features will also be displayed on the HUD if you are in Street Mode.


Object Number: 1462770  Size: B2

Be sure to continue scanning your displays, controls and driving environment just as you would in a vehicle without HUD. If you never look at your instrument panel cluster, you may not see something important, such as a warning light. Under important warning conditions, the CHECK GAGES warning will illuminate in the HUD. View your Driver Information Center (DIC) for more information.

The HUD controls are located to the left of the steering wheel.

To adjust the HUD so you can see it properly, do the following:

  1. Start your engine and press the HUD dimmer control all the way up by pressing the (+) button.
  2. The brightness of the HUD image is determined by the light conditions in the direction your vehicle is facing and where you have the HUD dimmer control set. If you are facing a dark object or a heavily shaded area, your HUD may anticipate that you are entering a dark area and may begin to dim.

    It is possible for sunlight to enter the HUD making it difficult to see the image. The display will return to normal when the sunlight is no longer entering the HUD.

  3. Adjust the seat to a comfortable driving position. If you change your seat position later, you may have to re-adjust your HUD.
  4. Press the up or down arrows to center the HUD image in your view.
  5. The HUD image can only be adjusted up and down, not side-to-side.

  6. Press the dimmer control downward until the HUD image is no brighter than necessary.

To turn HUD off, press and hold the (-) button until the HUD display turns off.

If the sun comes out or it becomes cloudy, you may need to adjust the HUD brightness again using the dimmer control. Polarized sunglasses could make the HUD image harder to see.

The HUD information can be displayed in one of six languages including English, Spanish, French, German, Italian or Japanese. The speedometer can be displayed in either English or Metric units.

To change the language and unit selections, see "OPTION" under DIC Controls and Displays .

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

To clean the HUD, spray household glass cleaner on a soft, clean cloth. 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 the ignition is on and you can't see the HUD image, check to see if:

    • Something is covering the HUD unit.
    • The HUD dimmer control is adjusted properly.
    • The HUD image is adjusted to the proper height.
    • Ambient light is low, in the direction your vehicle is facing.
    • A fuse is blown. See Fuses and Circuit Breakers .

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