With your fingers

In a 2008 Volvo S40, the cigarette lighter fuse is located in the fuse box, which is found under the dashboard on the driver's side. To access it, you may need to remove a panel or cover. The specific fuse for the cigarette lighter is usually labeled in the fuse diagram, which can be found on the cover of the fuse box or in the owner's manual. If the cigarette lighter is not functioning, check this fuse first for any signs of damage or a blown fuse.
