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 overloaded.
This could result in a fire.
- Always replace faulty fuses with specified new fuses containing the correct amperage.
NOTE Damage due to incorrect fuses
Using incorrect fuses can result in damage to electrical components or systems or their functions being considerably restricted.
- Use only fuses approved for Mercedes-Benz with the respective specified fuse rating.
Blown fuses must be replaced with fuses of the same rating, which you can recognize by the colour and the label. The fuse ratings and further information to be observed can be found in the fuse assignment diagram.
