Turn the INTENSITY knob counterclockwise until the HUD image is no brighter than necessary. To turn the HUD off, turn the HUD INTENSITY knob all the way counterclockwise. If the sun comes out, or it becomes cloudy, or if you turn on your headlamps, you may need to adjust the HUD brightness using the HUD INTENSITY knob. Polarized sunglasses could make the HUD image harder to see. Clean the inside of the windshield as needed to remove any dirt or film that reduces the sharpness or clarity of the HUD image. 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 fluid could leak inside the unit. If you cannot see the HUD image when the ignition is on, check to see if: The HUD unit is covered. The HUD INTENSITY knob is adjusted correctly. The HUD image is adjusted to the proper height. A fuse in the fuse panel may have blown. See Fuses and Circuit Breakers on page 5-101. If the HUD image is not clear, it could be too bright. Move the HUD INTENSITY knob counterclockwise. You may need to clean the windshield and HUD lens. Your windshield is part of the HUD system. If you ever have to have a new windshield, be sure to get one designed for HUD. If you do not, the HUD image may look blurred and out of focus. 3-24
