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.

The brightness of the HUD image is determined by the light conditions in the direction the vehicle is facing and where you have the HUD dimmer control set. If you are facing a dark object or a heavily shaded area, the 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.
