Checking and Replacing Fuses in Toyota Prius

If the headlights or other electrical components do not work, check the fuses.

Turn the ignition switch and inoperative component off. Pull the suspected fuse straight out and check it. If the fuse has blown, push a new fuse into the clip. Only install a fuse with the amperage rating designated on the fuse box lid.

If the new fuse immediately blows out, there is a problem with the electrical system. Have your Toyota dealer correct it as soon as possible.

Caution!

Never use a fuse with a higher amperage rating, or any other object, in place of a fuse. This may cause extensive damage and possibly a fire.
