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 speci-
fied new fuses having the correct amper-
age.
!
Only use fuses that have been approved for
smart vehicles and which have the correct
fuse rating for the system concerned. Oth-
erwise, components or systems could be
damaged.
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the com-
ponents 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 newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
