Fuses

Important safety notes

WARNING

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.

Always replace faulty fuses with the specified

new fuses having the correct amperage.

Only use fuses that have been approved

for Mercedes-Benz vehicles and which

have the correct fuse rating for the system

concerned. Otherwise, components or

systems could be damaged.

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.

Blown fuses must be replaced with fuses of

the same rating, which you can recognize by

the color and value. The fuse ratings are listed

in the fuse allocation chart.

If a fuse has blown, contact a breakdown

service or an authorized Mercedes-Benz

Center.

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.
