Fuses
fuses maintenance-fuses
- Left side: Normal, Right side: Blown
- The actual fuse/relay panel label may differ from the equipped items.
- A vehicle’s electrical system is protected from electrical overload damage by fuses.
- This vehicle has 2 (or 3) fuse panels, one located in the driver’s side panel bolster, and the other in the engine compartment near the battery.
- 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 melt.
- If the electrical system does not work, first check the driver’s side fuse panel.
- If the replacement fuse blows, this indicates an electrical problem.
- Avoid using the system involved and immediately consult an authorized Kia dealer.
- Three kinds of fuses are used: blade type for lower amperage ratings, cartridge type, and multi fuse for higher amperage ratings.
WARNING
- Fuse replacement
- 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.
- Do not arbitrarily modify or add electric wiring to the vehicle.
CAUTION
- Do not use a screwdriver or any other metal object to remove fuses because it may cause a short circuit and damage the system.
NOTICE
- When replacing a fuse, turn the ignition ‘OFF’ and turn off the switches of all electrical devices then remove the battery (-) terminal.
- The actual fuse/relay panel label may differ from the equipped items.
WARNING
- Electrical fire
- Always ensure replacement fuses and relays are securely fastened when installed.
- Failure to do so can result in a vehicle fire.
- Do not remove fuses, relays and terminals fastened with bolts or nuts.
- The fuses, relays and terminals may be fastened incompletely, and it may cause a possible fire.
- If fuses, relays and terminals fastened with bolts or nuts are blown, consult with an authorized Kia dealer.
CAUTION: 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.
CAUTION
- Do not input any other objects except fuses or relays into fuse/ relay terminals such as a screwdriver or wiring. It may cause contact failure and system malfunction.
- Do not plug in screwdrivers or aftermarket wiring into the terminal originally designed for fuse and relays only. The electrical system and wiring of the vehicle interior may be damaged or burned due to contact failure.
- If you directly connect the wire on the taillamp or replace the bulb which is over the regulated capacity to install trailers etc., the inner junction block can get burned.
WARNING
- Electrical wiring repairs
- All electrical repairs should be performed by authorized Kia dealerships using approved Kia parts.
- Using other wiring components, especially when retrofitting multimedia or theft alarm systems, car phones or radios may cause vehicle damage and increase the risk of a vehicle fire.
NOTICE
- Remodeling prohibited
- Do not rewire your vehicle in any way as doing so may affect the performance of several safety features in your vehicle.
- Rewiring your vehicle may also void your warranty and cause you to be responsible for any subsequent vehicle damage which may result.
Inner panel fuse replacement
Fusesinner panel fuse replacement
- Turn the ignition switch or ENGINE START/STOP button and all other switches off.
- Open the fuse panel cover.
- Pull the suspected fuse straight out. Use the removal tool provided in the main fuse box in the engine compartment.
- Check the removed fuse; replace it if it is blown. Spare fuses are provided in the instrument panel fuse panel (or 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, consult an authorized Kia dealer.
- 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 cigarette lighter fuse.
- If the headlamps or taillamps, stoplights, courtesy lamps, and daytime running lights (DRL) do not work and the fuses are OK, consult an authorized Kia dealer.
Engine compartment fuse replacement
Fusesengine compartment fuse replacement
- Turn the ignition and all other switches off.
- Remove the fuse panel cover by pressing the tab and pulling the cover-up.
- 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, consult an authorized Kia dealer.
CAUTION: After checking the fuse panel in the engine compartment, securely install the fuse panel cover through the audible clicking sound. If not, electrical failures may occur from water contact.
NOTICE: If the multi fuse is blown, consult an authorized Kia dealer.
NOTICE: The electronic system may not function correctly even when the engine room and internal fuse box fuses are not disconnected. In such a case, the cause of the problem may be the disconnection of the main fuse (BFT type), which is located inside the positive battery terminal (+) cap. Since the main fuse is designed more intricately than other parts, visit the nearest authorized Kia dealer.
Main fuse (Multi fuse)
If the main fuse is blown, it must be removed as follows:
- Turn off the engine.
- Disconnect the negative battery cable.3. Remove the nuts shown in the picture above.
- Replace the fuse with a new one of the same rating.
- Reinstall in the reverse order of removal.
CAUTION
- Visually inspect the battery cap for secure closing.
- If the battery cap is not securely latched, the electrical system may be damaged to due the influx of moisture into the system.
Fuse/relay panel description
- Inside the fuse/relay panel covers you can find the fuse/relay label describing the fuse/relay name and capacity.
NOTICE: Not all fuse panel descriptions in this manual may apply to your vehicle. It is accurate at the time of printing. When you inspect the fuse panel in your vehicle, refer to the fuse panel label.

The fuse box is typically located in the engine compartment or the driver’s side kick panel. Refer to your owner’s manual for the exact location.
Basic tools like needle-nose pliers or a fuse puller can be used to remove and replace fuses.
Depending on the model, there may be a cover that needs to be removed. Refer to the owner’s manual for specific instructions on accessing the fuse box.
The fuse diagram indicates the function and location of each fuse in the vehicle, helping you identify the fuse related to a specific electrical component.
Inspect the fuse for a melted or broken fuse element. If in doubt, use a multimeter to check for continuity.
Yes, there are often spare fuses in the fuse box or a designated compartment in the vehicle.
No, it’s crucial to replace a blown fuse with the same amperage rating to prevent damage to the electrical system.
Refer to the fuse diagram in the owner’s manual to identify the fuse associated with a particular system or component.
Overloading the electrical system, short circuits, or using faulty accessories can lead to blown fuses.
Regularly inspect fuses and replace any that are blown. This is especially important if you experience electrical issues in your vehicle.
Issues such as malfunctioning lights, inoperative power windows, or non-functional accessories may indicate a blown fuse.
Refer to the owner’s manual for any specific instructions, but generally, you can replace fuses in any order. Ensure the vehicle is turned off before replacing fuses.
