Important safety notes

WARNING
Only use fuses that have been approved for
Mercedes-Benz vehicles and that have the
correct fuse rating for the systems
concerned. Do not attempt to repair or bridge
faulty fuses. Using fuses that have not been
approved or attempting to repair or bridge
faulty fuses could cause the fuse to be
overloaded and result in a fire. Have the cause
traced and rectified at a qualified specialist
workshop.
! 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 newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
