Locate the correct fuse in the fuse lists for the various fuse boxes.
Pull out the fuse and check from the side to see whether the curved wire has blown.
If this is the case, replace it with a new fuse of the same colour and amperage.
Note
Some fuse boxes may contain special tweezers for a better grip on the fuse.
Warning
Never replace a fuse with a foreign object or a fuse of higher amperage. This may lead to damage to the electrical system and cause fire.
Contact an authorised Volvo workshop about replacing the fuses not described in the owner's manual.
