Doors, Hood and Trunk: Testing and Inspection

Oiling the Door Hinges

Check the door locks, lid locks and safety hooks of the front lid to ensure that they are secure and functioning properly.

Secure fit inspection

- Tightening torque of the fastening screws for door lock, front and rear lid lock as well as of the fastening nuts for the upper parts of the lock for the front and rear lid.

Tightening torque: 10 Nm (7.5 ftlb.)

Door lock function test

- Check that the door lock engages in two stages through the locking wedge when the doors are closed and that it disengages again when the door handle is operated (inside and outside).

Lid lock, front and rear

- Check that the lid locks engage by insertion of the lock upper parts when the lids (front and rear) are closed and that they disengage again when the lid releases are pulled.

Safety hook, front lid

1. Check that the front lid is held down by the safety hook after the lid lock is opened.
At the same time, the safety hook must engage in the retaining plate at its lowest point.

2. Check that the return spring pulls back the safety hook until it makes contact with the base plate of the lock upper part when the lid is open.
