Replacing fuses All electrical functions and components are protected by a number of fuses in order to protect the vehicle’s electrical system from damage by short circuiting or overloading.
- Refer to the fuse diagram to locate the fuse.
- 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.
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 performed incorrectly, significant damage can be caused to the electrical system.
