5-32 Instruments and Controls 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. English Shown, Metric Similar Format Three: This display includes much of the information in Format One along with a circular tachometer, but without outside air temperature and compass heading. All formats will show the turn-by-turn navigation information and provide details about the next driving maneuver to be made. When you near your next maneuver, the HUD will display a distance bar that will empty the closer you get to your maneuver. All navigation information is provided to the HUD by the navigation radio or OnStar service, for vehicles that have these features. English Shown, Metric Similar The HUD image displayed on the windshield will automatically dim and brighten to compensate for outside lighting. However, the HUD brightness control can still be adjusted as needed. 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. 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.
