How to Adjust the Two Screws on the Cruze Headlights?
2 Answers
Drive the car to a relatively flat road surface, adjust the low beam point to 30 meters apart with two points overlapping, and adjust the high beam point to be parallel to the ground. Park the car about 7.5 meters away from the wall, ensuring that the car is perpendicular to the wall and level with the ground. Adjust the vertical adjustment screw until the headlight beam is centered on the tape on the wall. Measure the height of the headlights and the beam on the wall. If the heights are consistent, it indicates that the headlight adjustment is perfect.
Last time I adjusted the headlights on a 2009 Cruze, the positions of the two adjustment screws were crucial. The vertical one is located at the top of the headlight housing near the fender and can be turned with a Phillips screwdriver. The horizontal one is on the side near the bumper, and you'll need to remove the air filter box to access it. Remember to park the car on level ground, 5 meters from a wall, with the low beams on. First, adjust the vertical screw to align the main light spot on the wall with the original headlight height. Then, adjust the horizontal screw to position the cutoff line at a 15-degree angle in front of the driver's side. Finally, walk around the car to check that both light patterns are symmetrical and not conflicting. The whole process is best done with two people—it took me half an hour in my garage to get it right. If not adjusted properly, it can blind other drivers.
