Fuse Box: 2019 - 2021 Kia Forte Fuse Box Diagram

2021 Kia Forte (Cerato)

Fuses and Relays

Left side : Normal , Right side : Blown

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, 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 rating, 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-on 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", turn off switches of all electrical devices, and then remove the battery (-) terminal.
• The actual fuse/relay panel label may differ from equipped items.

WARNING - Electrical Fire
Always ensure replacements fuses and relays are securely fastened when installed. Failure
to do so can result in a vehicle fire.

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, such as a screwdriver or wiring, except fuses or relays into the fuse/relay terminals.
• 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 regulated
capacity to install trailers etc., the inner junction block can get burned.

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 - Electrical wiring repairs
All electrical repairs should be performed by authorized Kia dealerships using approved Kia
parts. Using other wiring components, especially when retrofitting an Infotainment system
or a theft alarm system, remote engine control, car phone or radio 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.

✽ NOTICE - Window tinting precaution
Window tint (especially metallic film) might cause communication errors or poor radio reception, and a malfunctioning automatic lighting system due to reflections from the mirror tint inside the vehicle. The tint installation solution used might also leak into the electronic components, causing malfunctions or damage.

Inner panel fuse replacement

1. Turn the ignition switch and all other switches off.

2. Open the fuse panel cover.
If the switch is located in the “OFF” position, a caution indicator will be displayed in the cluster.
To identify the location of a specific fuse, please refer to the inside of the fuse panel cover and the description list in this section.

Fuse Puller Location

3. Pull the suspected fuse straight out. Use the removal tool provided on the engine compartment fuse panel cover.
4. Check the removed fuse; replace it if it is blown.
Spare fuses are provided in the engine compartment fuse panel.
5. 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 head lamp, turn signal lamp, stop signal lamp, fog lamp, Daytime Running Lights (DRL), tail lamp, High mounted stop lamp (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 malfunction even without any problem to the lamps, have the vehicle checked by an authorized Kia dealer for assistance.

Engine compartment fuse replacement

1. Turn the ignition switch and all other switches off.
2. Remove the fuse panel cover by pressing the tab and pulling the cover up.

3. 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.
4. 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
Always securely install the fuse panel cover in the engine compartment to protect against
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

✽ NOTICE
Do not disassemble nor assemble a 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

✽ NOTICE
Do not disassemble nor assemble a main 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.

NOTICE
The electronic system may not function correctly even when the engine compartment and internal fuse box’s individual fuses are not disconnected.
If this occurs, the cause of the problem may be 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.

Battery fuse

If the battery fuse is blown, it must be removed as follows:
1. Disconnect the negative battery cable.
2. Replace the fuse with a new one of the same rating.
3. 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 due to influx of moisture into the system.
