Changing Fuse Precautions
An overloaded fuse needs to be replaced to restore function to the electrical component it protects.
Locate the correct fuse in the fuse diagrams for the different fuse boxes.
Details for mileage, safety, and performance.
Pull out the fuse and examine it from the side to determine if the curved metal wire in the fuse is intact.
If the wire is broken, replace the fuse with a new fuse of the same color and amperage.
Note
Some fuse boxes contain special pliers to make it easier to grip the fuse.
Warning
Never use a foreign object or a fuse with a higher amperage than that specified to replace a fuse. This could cause significant damage to the electrical system and possibly lead to a fire.
Warning
Contact an authorized Volvo workshop for assistance replacing fuses not listed in the Owner’s Manual. If fuse replacement is performed incorrectly, significant damage can be caused to the electrical system.
