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 amper-
age, the electric line could be overloaded.
This could result in a re.
#
Always replace faulty fuses with speci-
ed new fuses containing the correct
amperage.
*
NOTE Damage due to incorrect fuses
Electrical components or systems may be
damaged by incorrect fuses, or their function-
ality may be signicantly impaired.
#
Only use fuses that have been approved
by Mercedes-Benz and which have the
correct fuse rating.
Blown fuses must be replaced with fuses of the
same rating, which you can recognise by the col-
our and fuse rating. The fuse ratings and further
information to be observed can be found in the
fuse assignment diagram.
