So that the car does not remain completely de-energized in the event of any malfunction, the fuses are distributed between various electrical circuits. However, the connections between the battery, alternator, starter and ignition switch are not fused.
Blade-type fuses
The Mercedes car has flat-shaped fuses with blade-type contacts. Two flat contact plates are inserted into their plastic case, connected by a fusible insert.
Two main ratings are used: overload fuses for 30 or 40 A are installed in the engine compartment and under the rear seat. Fuses of a smaller value cover the area from 7.5 to 20 A. There is a special tool in the standard kit for easy removal of the fuses. Don't forget about timely replacement - spare fuses are located in the front fuse box.
Up to 56 fuses can be installed in a Mercedes vehicle.
Fuse Location
The location of the fuses in various modifications of the E-class depends on the year of manufacture and equipment variant. The location of the fuses in your vehicle can be found in the owner's manual or on the fuse box cover.
The color of the plastic body of the fuse corresponds to the specified maximum current rating (A): brown - 7, 5; red - 10; blue - 15; yellow - 20; green - 30; orange - 40.
