Checking and also Replacing Fuses

The fuses in your car serve to close under faulty circuits. If a fuse blows, every the contents on the circuit and their attributes stop operating. If a fuse has blown, the inside element will it is in melted. Puffy fuses should be changed with fuses that the very same rating, which you can recognize by the color and value. The fuse ratings are listed in the fuse allocation chart. The fuse allocation chart is located in the vehicle tool kit in the storage compartment under the trunk/cargo compartment floor.

If a newly put fuse likewise blows, have actually the reason traced and also rectified at a qualified specialist workshop, e.g. One authorized Mercedes-Benz Center.


Notice

Before transforming a fuse, for sure the vehicle against rolling away and switch off all electrical consumers.Always disconnect the battery prior to servicing high current fuses.Always replace faulty fuses through the specified new fuses having the exactly amperage. If friend manipulate or leg a faulty fuse or if you replace it v a fuse with a higher amperage, the electric cables might be overloaded. This could result in a fire. Over there is a hazard of one accident and injury.Only use fuses that have been authorized for Mercedes-Benz vehicles and also which have actually the exactly fuse rating for the device concerned. Otherwise, materials or systems can be damaged.

Make sure that the windshield wipers are turned off.Open the hood.Use a dry towel to remove any moisture indigenous the fuse box.To open: eliminate lines (2) from the guides.Move present (2) aside. Course the lines behind connection (3) to execute this.Open clamp (1).Remove the fuse crate cover forwards.
