Fuses

Notes on changing fuses

The fuses in your vehicle serve to close down faulty circuits. If a fuse blows, all the components on the circuit and their functions will fail.

Blown fuses must be replaced with fuses of the same rating (which can be recognised by the colour and amperage) and which have the amperage specified in the fuse allocation chart. A Mercedes-Benz Service Centre will be happy to advise you.

Risk of fire

Only use fuses that have been approved for Mercedes-Benz vehicles and which have the correct amperage for the system concerned. Do not attempt to repair or bridge faulty fuses. A circuit overload could otherwise cause a fire. Have the cause traced and rectified at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.

If the newly inserted fuse also blows, have the cause traced and rectified at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.

Only use fuses that have been approved for Mercedes-Benz vehicles and which have the correct amperage for the system concerned. Otherwise, components or systems could be damaged.

The fuses are located in various fuse boxes:

  • Main fuse box on the driver's side of the dashboard

  • Fuse box in the boot, on the left-hand side of the vehicle
