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
Electrical components or systems may be damaged by incorrect fuses, or their functionality may be significantly 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 colour and the label. The fuse ratings and further information to be observed can be found in the fuse assignment diagram.
Fuse assignment diagram: on the fuse box in the rear passenger compartment More.
NOTE Damage or malfunctions caused by moisture
Moisture may cause damage to the electrical system or cause it to malfunction.
When the fuse box is open, make sure that no moisture can enter the fuse box.
When closing the fuse box, make sure that the seal of the lid is positioned correctly on the fuse box.
If the newly inserted fuse also blows, have the cause traced and rectified at a qualified specialist workshop.
Ensure the following before replacing a fuse:
The vehicle is secured against rolling away.
All electrical consumers are switched off.
The vehicle is switched off.
