The HUD image can only be adjusted up and down, not side-to-side. 3. Press the DIMMER button until the DIC reads HUD DIMMING. Then use the brightness button to adjust the desired intensity. 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 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. To turn off the HUD, press the brightness button down until the image disappears. Polarized sunglasses could make the HUD image harder to see. As light shines out from the HUD, it is possible for light to shine back in. In rare occurrences, when the sun is at a specific angle and position, the sun's rays can shine back into the HUD. When this occurs, the display device within the HUD will be temporarily illuminated. The event will end when the vehicle's angle to the sun changes. +!- (Brightness): This button is used to adjust the brightness of the HUD and the instrument panel cluster.
