Fuses and fuseboxes
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.
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
Orange wiring may only be handled by qualified personnel.
WARNING
Several components in the vehicle work with high voltage that can be hazardous in case of an incorrect procedure. Do not touch anything not clearly described in this Owner’s Manual.
If any electrical component or function is not responding, the component may have blown a fuse due to temporary overload. If the same fuse blows repeatedly, there may be a problem with the component. Volvo recommends contacting an authorized Volvo workshop to have the components checked.

Replacing fuses
All electrical functions and components are protected by several fuses 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 colour 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.
