Replacing fuses All electrical functions and components are pro- tected by a number of fuses in order to protectthe vehicle's electrical system from damage byshort circuiting or overloading.
1. Refer to the fuse diagram to locate the fuse.
2. Pull out the fuse and examine it from theside 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 amperage.
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 possiblylead to a fire.
WARNING
Contact an authorized Volvo workshop for assistance replacing fuses not listed in theOwner's Manual. If performed incorrectly, sig-nificant damage can be caused to the electri-cal system.
