Fuses and Fuse Box Diagram: 2022 Kia Niro PHEV Guide
Fuse boxes are very important in the 2022 Kia Niro PHEV because they keep electrical circuits from getting damaged by overloading or short circuits. A fuse is a small device that is meant to break the circuit when too much current runs through it. This keeps electrical hazards from happening. These fuses are kept in the fuse box, which is also called the fuse panel or fuse block. The fuse box is usually easy to get to inside the car. It’s important to know the fuse box diagram, which shows where each fuse is located and what it does in the car’s electrical system. This picture can help you figure out what’s wrong with your electricity and quickly replace blown fuses. Owners of the Kia Niro PHEV can easily find and fix electrical problems by looking at the fuse box diagram. This keeps their car safe and reliable.

FUSES
Left side: Normal, Right side: Blown
A vehicle’s electrical system is pro-tected 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.
Always replace a blown fuse with one of the same rating.
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 alu-minum 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 the 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.
Inner panel fuse replacement
- Turn the engine start/stop button to the OFF position 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.
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.
- 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.
CAUTION - Do not input any other objects except fuses or relays into fuse/relay terminals, such as a driver 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 taillight or replace the bulb which is over the reg-ulated capacity to install trailers, etc., the inner junction block can get burned.
- 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.
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 power outlet fuse.
If the headlamp, turn signal lamp, stop signal lamp, fog lamp, DRL, tail lamp, and HMSL do not work and the fuses are OK, check the fuse panel in the engine compartment. If a fuse is blown, it must be replaced.
NOTICE
If the headlamp, fog lamp, turn signal lamp, or tail lamp malfunctions even without any problem with the lamps, have the vehicle checked by an authorized Kia dealer for assis-tance.
CAUTION – Fuse Panel Covers
- Set all switches to ON before driving.
- If the vehicle is going to be unused for over 1 month, set all switches to OFF to prevent the batteries from draining.
- The contact points of the
switches may wear out with excessive use. Please refrain from excessive use of the switches (except for long-term parking for over 1 month).
Fuse switch
Always set the fuse switch to the ON position before using the vehicle.
If you move the switch to the OFF position, some items such as the audio and digital clock must be reset and the transmitter (or smart key) may not work properly. When the switch is Off, the caution indicator will be displayed on the instrument cluster.
Always place the fuse switch in the ON position while driving the vehicle.
If the switch is located in the “OFF” position, a caution indicator will be displayed in the cluster.
Engine compartment fuse replacement
- Turn the engine start/stop button to the OFF position 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 a 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, consult an authorized Kia dealer.
CAUTION
After checking the fuse panel in the engine compartment, securely install the fuse panel cover to protect against any electrical failure which may occur from water contact. Listen for the audible clicking sound to ensure the fuse panel cover is securely fastened.
Multi fuse
If the multi fuse is blown, it must be removed as follows:
- Turn off the engine.
- Disconnect the negative battery cable.
- Remove the nuts shown in the pic-ture above.
- Replace the fuse with a new one of the same rating.
- Reverse these steps to reinstall the multi-fuse.
NOTICE
Do not disassemble nor assemble the multi-fuse when it is secured with nuts and bolts. Incorrect or partial assembly torque may cause a fire. Have the vehicle checked by an authorized Kia dealer.
Main fuse (Plug-in Hybrid)
If the multi fuse is blown, it must be removed as follows:
- Turn off the engine.
- Disconnect the negative battery cable.
- Remove the nuts shown in the pic-ture above.
- Replace the fuse with a new one of the same rating.
- Reverse these steps to reinstall the multi-fuse.
NOTICE
The electronic system may not func-tion correctly even when the engine compartment and internal fuse box’s 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, have the vehicle checked by an authorized Kia dealer.
CAUTION
Visually inspect the battery cap to ensure it is securely closed. If the battery cap is not securely closed, moisture may enter the system and damage the electrical components.
WARNING – Random wiring is prohibited when retrofitting equipment
The use of random wiring in the vehicle might cause danger due to failure and damage to the vehicle’s performance.
Using random wires, especially when retrofitting AVN or theft alarm system, remote engine control, car phone or radio might damage the vehicle or cause a 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 vehi-cle may also void your warranty and cause you to be responsible for any subsequent vehicle damage which may result.

How to Replace the Fuse of the 2022 Kia Niro PHEV
To replace the fuse in a 2022 Kia Niro PHEV, you’ll need to follow these steps:
Materials:
- The new fuse of the correct amperage.
- Fuse puller or needle-nose pliers.
Instructions:
- Locate the Fuse Box: The fuse box in the Kia Niro PHEV is typically located under the dashboard on the driver’s side or in the engine compartment.
- Identify the Correct Fuse: Once you’ve located the fuse box, open it and locate the fuse that needs to be replaced. Each fuse should be labelled with its function. See the diagram on the fuse box cover to identify the specific fuse for the component that isn’t working.
- Disconnect the Battery: To avoid any electrical mishaps, it’s a good idea to disconnect the car battery before replacing the fuse. This step is optional but recommended for safety purposes.
- Remove the Fuse: Using a fuse puller tool or a pair of needle-nose pliers, carefully remove the faulty fuse from its slot. Be gentle to avoid damaging the fuse or the fuse box.
- Install the New Fuse: Take a new fuse of the same amperage rating and insert it into the slot where the old fuse was removed. Make sure it fits snugly into place.
- Reconnect the Battery: If you disconnected the car battery earlier, reconnect it once the new fuse is in place.
