Notes on electrical fuses
& WARNING Risk of accident and injury
due to overloaded lines
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher
amperage, the electric line could be overloa‐
ded.
This could result in a fire.
#
Always replace faulty fuses with speci‐
fied new fuses containing the correct
amperage.
*
NOTE Damage caused by incorrect fuses
Incorrect fuses may cause damage to electri‐
cal components or systems.
#
Only use Mercedes-Benz approved
fuses with the correct fuse rating.
Blown fuses must be replaced with fuses of the
same rating, which you can recognize by the
color and fuse rating. The fuse ratings are listed
in the fuse assignment diagram.

box.
