ELECTRICAL COMPONENTS 2. Make sure the inoperative component is turned off. Pull the suspected fuse straight out with the pull-out tool and check it. If it has blown, push a new fuse into the clips. " Good " Blown a. Look carefully at the fuse. If the thin wire is broken, the fuse has blown. If you are not sure or if it is too dark to see, try replacing the suspected fuse with one of the same value that you know is good. b. Only install a fuse with the amperage rating designated on the fuse box lid. If you do not have a spare fuse, in an emergency you can pull out the "CIG", "RADIO NO.1" or "SEAT HEATER" fuse, which may be dispensable for normal driving, and use it if its amperage rating is the same. If you cannot use one of the same amperage, use one that is lower, but as close to the rating as possible. If the amperage is lower than that specified, the fuse might blow out again but this does not indicate anything wrong. Be sure to get the correct fuse as soon as possible and return the substitute to its original clips. 615
