To adjust the HUD so you can see it properly: 1. Start your engine and slide the HUD dimmer control all the way up. 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 causing all of the graphics to light up. The display will return to normal when the sunlight is no longer entering the HUD. The HUD controls are located to the left of the steering wheel. 2. Adjust the seat to your driving position. If you change your seat position later, you may have to re-adjust your HUD. 3. Press the DISPLAY switch up or down to center the HUD image in your view. The HUD image can only be adjusted up and down, not side-to-side. 4. Slide the dimmer control downward until the HUD image is no brighter than necessary. To turn HUD off, slide the switch to OFF. 2-115
