Care of the HUD
Clean the inside of the windshield as needed to remove any dirt or film that could reduce the sharpness or clarity of the HUD image.
To clean the HUD lens, use a soft, clean cloth that has household glass cleaner sprayed on it. Wipe the HUD lens gently, then dry it. Do not spray cleaner directly on the lens because the cleaner could leak into the unit.
