For this, special hinges have been developed to facilitate removal and installation without disturbing the adjustments. This makes it easier to work with self-repairs: after the dismantling of the door described below, no further adjustment is required. In the traditional order of dismantling the door with the removal of hinges, the need for adjustment, of course, remains. In this case, the surfaces under the hinges should be painted.
All connections in the door are made through a multi-pin connector. Its opening and closing is carried out using a special tool. You can also use a screwdriver for this, but it must fit exactly into the hole.
Warning! Belt tensioners and self-repair. The front seats of the Mercedes are equipped with seat belt pretensioners that are activated in the event of an accident. The pretensioners are activated by the action of a gas generator activated by the supply of current. Self-repair of this system is prohibited. The installation and removal of pretensioners is the task of workshop professionals, who must comply with strict safety requirements.
Warning! Be careful when working under the vehicle. When carrying out body work, it is not allowed to use an impact screwdriver or hammer in the area of the seat belt roller mechanisms without special care: the pretensioners are very sensitive to vibrations and shocks and can therefore work.
