Of course it can be adjusted. When installing a car in the assembly workshop of Chongqing Vehicle Factory, including other installation parts, especially exterior decoration parts, the gap and segment difference need to be adjusted by the field assembler to meet the dimensional tolerance requirements. The adjustment of the garage has no technical content. It's all done by brute force, about the same size up and down. For example, the tolerance of 3 1 mm, the upper clearance of 3.5mm and the lower clearance of 2.5mm are all within the tolerance range, and the garage will release them. If you have a vernier caliper or clearance gauge, just measure it up and down. If it is big or small, hold the lower edge of the door by hand and pull it up hard, and vice versa.
