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 a fire. Contact an authorized Volvo workshop about replacing the fuses not described in the owner’s manual. If an electrical component or function does not work, it may be because the component’s fuse was overloaded and has blown. If the same fuse blows repeatedly then there is a fault in a component. Volvo recommends contacting an authorized Volvo workshop for checking.

Replacing a fuse
- A fuse that has been overloaded needs to be changed in order to restore the function of the electrical component it is protecting.
- 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 color and amperage.
Some fuse boxes may contain special tweezers for a better grip on the fuse.
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 a fire.

Fuses under the left-hand front seat
Updated 11/15/2021
Fuses under the left-hand front seat protect, amongst other things, electrical sockets, displays and door modules.
Positions
Fuse locations are shown on the inside of the cover. Functions and components in the fuse table cover several models and engine alternatives. A fuse description can therefore apply to fewer than those in the table, or be completely missing, depending on how the car is equipped. If a position has several values in the table, the value depends on variations in equipment level. In which case, follow the value of the fuse being replaced. In the event of doubt – contact a workshop. An authorized Volvo workshop is recommended.
