Those are on the bottom part to adjust the gap down there when closed I believe. Docs and mine are off up by the hinge. I think you need to loosen the two bolts on the hinge to adjust it.I saw a video about adjusting the trunk alignment yourself. I'll try to find it. Basically there are about four round black knobs that come to rest on matching pads. The knobs just twist by hand to adjust how far in/out they sit against the matching pads.
