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. 2. Adjust the seat to a comfortable driving position. If you change your seat position later, you may have to re-adjust your HUD. 3. Press the up or down arrows to center the HUD image in your view. The HUD image can only be adjusted up and down, not side-to-side. 4. 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 on page 206. 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 not 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 on page 420. Keep in mind that your windshield is part of the HUD system. See Windshield Replacement on page 374. 175
