Important safety notes
Use only fuses approved for Mercedes-Benz and of the rating specified for the systems concerned. Do not repair or bridge defective fuses. If unapproved fuses or repaired or bridged fuses are used, a fire could start due to overload. Have an qualified workshop find and eliminate the cause of the problem.
Use only fuses approved for Mercedes-Benz and of the rating specified for the system concerned. Use only fuses marked "S". Otherwise, components or systems could be damaged.The vehicle's fuses serve to interrupt the power supply to defective electrical circuits. When a fuse blows, the consumers connected downstream of it no longer function.
Blown fuses must be replaced with fuses of the same type (same color and same amperage).
Refer to the fuse allocation chart to find the amperage rating of each fuse.
If the new fuse also blows, have a qualified workshop find and eliminate the cause of the problem.
