Check with a level that both parts of the cross are straight. Then back your car up to a distance of between 7 and 10 metres. For the rest of the process here are the steps to stick to:
- Open your bonnet, find the screws for horizontal and vertical control of the headlights of your GMC Acadia (they are in general marked, and those on top must adjust the verticality and the one on the side handles the horizontality of the adjustment).
- Use a cloth or something else to hide the projector on which you are not making the modification.
- Using the screws to make the horizontal modification, you should have the most intense part of the beam which should be a little to the right of the vertical line noted on the wall
- With regard to vertical modification, you will have to use the screw to try to position the upper end of the beam at the level of the horizontal marking on the wall, or slightly down below.
- Once finished, check that the headlights setting of your GMC Acadia is coherent, do not hesitate to check it after you have driven it, oftentimes it may move.
