Checking and Replacing 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 stop operating. If a fuse has blown, the inside element will be melted. Blown fuses must be replaced with fuses of the same rating, which you can recognize by the color and value.

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

Notice

  • Before changing a fuse, secure the vehicle against rolling away and switch off all electrical consumers.
  • Always disconnect the battery before servicing high current fuses.
  • Always replace faulty fuses with the specified new fuses having the correct amperage. If you manipulate or bridge a faulty fuse or if you replace it with a fuse with a higher amperage, the electric cables could be overloaded. This could result in a fire. There is a risk of an accident and injury.
  • Only use fuses that have been approved for Mercedes-Benz vehicles and which have the correct fuse rating for the system concerned.
