Fuses and fuseboxes All electrical functions and components are protected by a number of fuses in order toprotect the vehicle's electrical system fromdamage by short circuiting or overloading.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possi-bly lead to a fire.
If any electrical component or function is not responding, the component may have blown afuse due to temporary overload. If the samefuse blows repeatedly, there may be a prob-lem with the component. Volvo recommendscontacting an authorized Volvo workshop tohave the component checked.

Replacing fuses
All electrical functions and components are protected by a number of fuses in order toprotect the vehicle's electrical system fromdamage by short circuiting or overloading.
1. Refer to the fuse diagram to locate the fuse.
2. Pull out the fuse and examine it from the side to determine if the curved metal wire in the fuse is intact.
3. If the wire is broken, replace the fuse with a new fuse of the same color and amper-age.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possi-bly lead to a fire.
WARNING
Contact an authorized Volvo workshop for assistance replacing fuses not listed in theOwner's Manual. If fuse replacement isperformed incorrectly, significant damagecan be caused to the electrical system.
