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.
Some fuse boxes may contain special tweezers for a better grip on the fuse.
Never use a foreign object or a fuse with an amperage higher than that specified when replacing a fuse. This could cause significant damage to the electrical system and possibly lead to fire.
Contact an authorised Volvo workshop about the fuses not mentioned in the owner's manual. If replacing the fuse is not performed correctly, it can cause serious damage to the electrical systems.
