Circuit/System Description

The head-up display (HUD) information (image) down or information (image) up switch is used to vertically adjust the HUD image on the windshield to accommodate various vehicle operator heights. The HUD monitors the image down or image up switch signal circuit in order to adjust image positions. When the HUD information down or information up switch is depressed and the ignition is in the RUN position, the switch signal to the HUD is low.
