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, Temperature and Fuel 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 5,750 rpm (6,250 rpm on Z06), just prior to reaching the engine fuel cut-off mode.
    • Check Gages Icon

There are five HUD selections that you can choose to view in the HUD display. By pressing and holding the PAGE button, you can scroll through these pages in the following order:

    • Speed Only
    • Speed and Gage
    • Speed, Tachometer and Gage
    • Speed and Tachometer
    • Tachometer Only

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

Gages can be scrolled through by tapping the PAGE button (only when a gage is displayed). The gages shown are the following:

    • Oil Pressure
    • Coolant Temperature
    • Fuel Level

The selections that you choose will remain in the HUD display until they are changed.

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 icon 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 slide the HUD dimmer control all the way up.
  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 causing all of the graphics to light up. 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 top or bottom of the DISPLAY switch to center the HUD image in your view.
  5. The HUD image can only be adjusted up and down, not side-to-side.

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

To turn HUD off, slide the switch to 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.

To change from English to metric units, press the E/M button located to the right of the steering wheel.

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, in the direction your vehicle is facing, is low.
    • A fuse is blown. See Fuses and Circuit Breakers .

Keep in mind that your windshield is part of the HUD system. If you ever have to have your windshield replaced, be sure to get one that is designed for HUD or your HUD image may look blurred and out of focus.
