The HUD controls are located to the left of the steering wheel. 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. To adjust the HUD so you can see it properly, do the following: 1. Start your engine and press the HUD dimmer control all the way up by pressing the (+) button. 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 making it difficult to see the image. The display will return to normal when the sunlight is no longer entering the HUD. 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 3-48. Clean the inside of the windshield as needed to remove any dirt or film that reduces the sharpness or clarity of the HUD image. 3-23
