For this purpose, special hinges have been developed that facilitate removal and installation without disturbing the adjustments. This also makes the work easier when doing repairs yourself: after the door dismantling procedure described below, subsequent adjustment is not required. With the traditional procedure for dismantling the door with the removal of the 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. It is opened and closed using a special tool. You can use a screwdriver for this, but it must fit the hole exactly.
Warning! Belt tensioners and self-repair. The front seats of the Mercedes are equipped with seat belt tensioners that are triggered in the event of an accident. The pretensioners are triggered by a gas generator activated by the supply of current. Self-repair of this system is prohibited. Installation and removal of pretensioners is the task of service station specialists, who must comply with strict safety requirements.
Warning! Be careful when working under the vehicle. When performing bodywork, do not use an impact screwdriver or hammer in the area of the seat belt rollers without extreme caution: the pretensioners are very sensitive to vibrations and impacts and may therefore be triggered.
