How can headlights and fog lights be adjusted for proper alignment and optimal visibility for Buick Enclave,Chevrolet Traverse and GMC Acadia?

Headlights and fog lights can be adjusted to ensure proper alignment and optimal visibility. For composite headlights, there are adjustment screws that control the up-and-down movement, but left-and-right movement is not adjustable. To adjust the headlights, a blank wall 25 feet in front of the vehicle and a level floor are needed. Position masking tape on the wall in reference to the vehicle centerline and the centerlines of both headlights. Measure the height of the headlight reference marks from the ground and position a horizontal tape line on the wall at the same height. With the vehicle sitting level, the gas tank half-full, and no heavy load, turn on the low beams and adjust the adjusting screw to position the high-intensity zone eight inches below the horizontal line. To ensure proper adjustment, it is recommended to have the headlights adjusted professionally. Similarly, fog lights can also be adjusted like headlights. Position tape on a wall 25 feet in front of the vehicle and tape a horizontal line representing the height of the fog light centers, as well as another line four inches below. Remove the fasteners from the front portion of the inner fender splash shield to access the adjustment screws for the fog lights. Adjust the pattern on the wall so that the top of the fog light beam meets the lower line.

How do you remove the headlight housing on Buick Enclave,Chevrolet Traverse and GMC Acadia?

Disconnect the cable from the negative battery terminal. Remove the front bumper cover. Remove the headlight housing mounting bolts. Gently pull the headlight housing from the radiator support, then disconnect the electrical connector. Installation is the reverse of removal. If you are reusing the original headlight assemblies, there is no need to readjust the headlight aim. But if you are replacing the assemblies, set the adjustment cam to its base setting about six turns from completely seated. This will aid in aligning the bumper cover.
