The picture is showing how to adjust bottom half of lower tailgate inward and outward. My vehicle had the bottom portion misaligned (sticking out too much). The adjustment had to be done a few times, as the top portion of lower tailgate has to be adjusted inward/outward as well. Pushing the top portion inward too much results in bottom portion coming out outward. You would have to balance them to move the whole tailgate inward or outward.
After adjusting, the tailgate does not need to be slammed to be closed, as had to be done before. Left and right locks close almost simultaneously with a push.
P.S. I wonder how many people have their tailgates misaligned. Post pictures
