Checking and Replacing Fuses

Fuses and circuit breakers protect your vehicle’s electrical system from overloading. If electrical components in the vehicle are not working, a fuse may have blown. Check the appropriate fuses before replacing any electrical components.

Look carefully at the fuse – a broken wire within the fuse identifies blown fuses. 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.

In case if you do not have a spare fuse, in an emergency you can pull out fuses, which may be dispensable for normal driving (for example, audio system, cigarette lighter, OBD, seat heater, and the like), and use it if its amperage rating is the same.


  • Always switch off the ignition system and the affected electrical circuit before replacing a fuse.
  • Always disconnect the battery before servicing high current fuses.
  • Never use a fuse of a higher amperage rating than that indicated, or use any other object in place of a fuse, even as a temporary fix. This can cause extensive damage or even fire.
  • If the replaced fuses blows again – contact a qualified and equipped service center.


The power distribution box is located under the right-hand side of the instrument panel.


To remove the trim panel for access to the fuse box, pull the panel toward you and swing it out away from the side and remove it.
To reinstall it, line up the tabs with the grooves on the panel, then push it shut.


To remove the fuse box cover, place a finger behind the PULL tab and your thumb above the PULL tab as shown in the illustration, then pull the cover off.
To reinstall it, place the top part of the cover on the fuse panel, then push the bottom part of the cover until you hear it click shut. Gently pull on the cover to make sure it is seated properly.
