You are refering to the auto-leveling switch for the HID's that is by the steering wheel. If you need to physically adjust the headlights is on the headlight itself. It's a gear like silver circle that you turn.fr0IVIan said:gf has a 2003 gt auto. the owner's manual refers to some sort of dial/switch to the left of the steering wheel that doesn't exist on this car, the only thing there is the power window lock. tech info on here refers to some nut or bolt you can turn, but when i turned the one i thought i saw on the headlight housing it had no effect.
