  2. Adjustment is made by following criteria:
    The width of a backlash of forward and back edge of doors should make 5–6,5 mm. Otherwise to move doors.
  3. The body contour should be co-ordinated: check up on all perimetre, whether there passes a middle line at height of door handles exactly, without steps, and whether the door too low or too highly is established.
  4. It is necessary to take care of a noise isolation. It can achieve by correct installation of doors: a first line back doors come on an average rack. On this place the rack/door distance is measured at the closed door. It should make 14,5 mm. Proceeding from this backlash other edges of doors are exposed: the first line of a forward door should be more deeply on 0,5–1 mm, than a forward wing. The back edge of a forward door should act on 0,5–1 mm further concerning a first line of a back door. And the back edge of a back door should act on the same distance over a back wing.
