Instruments and Controls 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. Format Three: This display includes all the information in Format One along with a circular tachometer, but without outside air temperature. 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 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. Polarized sunglasses could make the HUD image harder to see. 5-35 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 on page 10‑34. Is the HUD image too bright? Are the windshield and HUD lens clean? . . . . 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.

Do not spray cleaner directly on the lens because the cleaner could leak into the unit. If the HUD Image Is Not Clear . . If the HUD image is not correct, contact your dealer/retailer. Keep in mind that the windshield is part of the HUD system.
