The 2004 Cadillac SRX with HID lights has only a horizontal adjustment. There is no option to adjust the vertical plane. Under the hood, just behind the top of the lens assembly, you will find a hole that leads to an allen wrench adjustment. If you are not near a dealer that has a calibration screen, park on a flat surface about three feet away from a wall. Turn on headlights and adjust as you see fit. Once complete, back up about 20 feet and readjust as required. Not perfect but will do the job. However, the best scenario is a dealer or garage that has the calibration screen. Be wary, many say they do have one but will just use the wall after you have left your vehicle.
