Checking and Replacing Fuses
A vehicle’s electrical system is protected from electrical overload damage by fuses. If any of your vehicle’s lights, accessories, or controls do not work, check the appropriate circuit fuse. If a fuse has blown, the element inside the fuse will be broken or melted. Check those fuses first that protect the failed component, but check all the fuses before deciding that a blown fuse is not the cause. Replace any blown fuses with another with the same amperage (same color) and check the component’s operation.
Notice
- Before changing a fuse, check the ignition key has been removed and that all the other electric devices have been turned off/disabled.
- Do not use a screwdriver or any other metal object to remove fuses because it may cause a short circuit and damage the system.
- Never replace a fuse with anything but another fuse of the same rating. A higher capacity fuse could cause damage and possibly a fire. Never install a wire or aluminum foil instead of the proper fuse even as a temporary repair. It may cause extensive wiring damage and a possible fire.
- If the replacement fuse blows, this indicates an electrical problem. Avoid using the system involved and immediately consult at a qualified service center.
- When replacing a blown fuse or relay, make sure the new fuse or relay fits tightly into the clips. Failure to tightly install the fuse or relay may cause damage to the wiring and electric systems.
- Do not remove fuses, relays, and terminals fastened with bolts or nuts. The fuses, relays, and terminals may not be fastened correctly which may cause vehicle damage.
- If you do not have a spare, use a fuse of the same rating from a circuit you may not need for operating the vehicle, such as the power outlet fuse.
Instrument Panel Fuse Box
The fuse panel is behind the cover on the driver’s side dash panel.
To check and replace a fuse:
- Turn the ignition switch and all other switches off.
- Open the fuse panel cover. If the switch is located in the “OFF” position, a caution indicator will be displayed in the cluster.
- Pull the suspected fuse straight out. Use the removal tool provided on the engine compartment fuse panel cover.
- Check the removed fuse; replace it if it is blown. Spare fuses are provided in the engine compartment fuse panel.
- Push in a new fuse of the same rating, and make sure it fits tightly in the clips.

Engine Compartment Fuse Box
To check and replace a fuse:
- Turn the ignition switch and all other switches off.
- Remove the fuse panel cover by pressing the tab and pulling the cover up. When the blade type fuse is disconnected, remove it by using the clip designed for changing fuses located in the engine compartment fuse box. Upon removal, securely insert reserve fuse of the same rating.
- Check the removed fuse; replace it if it is blown. To remove or insert the fuse, use the fuse puller in the engine compartment fuse panel.
- Push in a new fuse of the same rating, and make sure it fits tightly in the clips. If it fits loosely, consults an authorized Kia dealer.
