FUSES
A vehicle’s electrical system is protected from electrical overload damage by fuses. This vehicle has 4 (or 5) 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. 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 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.
Inner panel fuse replacement
- 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.
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 to the lamps, have the vehicle checked by an authorized Kia dealer for assistance.
NOTICE
Fuse Panel Covers
-
Put all switches in ON when driving.
-
If the vehicle remains idle for over 1 month, put all switches in OFF to prevent the batteries from being discharged.
-
Excluding long-term parking for over 1 month, the contact points of switches may wear out upon extensive use. Please refrain from excessive use of switches.
Fuse switch
Always, put the fuse switch at the ON position. 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.
Engine compartment fuse replacement
If the main fuse is blown, it must be removed as follows:
- Turn off the engine.
- Disconnect the negative battery cable.
- 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.
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.
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 picture above.
-
Replace the fuse with a new one of the same rating.
-
Reinstall in the reverse order of removal.
NOTICE
The electronic system may not function correctly even when the engine room and internal fuse box’s individual 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.
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 be applicable 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.

How to Change Fuses of 2018 Kia Sorento
Certainly, here’s a detailed guide on changing fuses in a 2018 Kia Sorento:
-
Locate the Fuse Box: The fuse box in your 2018 Kia Sorento is typically situated under the dashboard on the driver’s side or in the engine compartment. Look for a small rectangular or square-shaped cover.
-
Identify the Fuse Box Cover: The fuse box cover usually has a diagram indicating the fuse positions and their corresponding functions.
-
Turn Off the Vehicle: Before proceeding, ensure the vehicle is turned off completely. Remove the key from the ignition for safety.
-
Access the Fuse Box: If the fuse box is inside the cabin, you may need to open the driver’s side door and kneel down to reach it comfortably. If it’s under the hood, prop the hood open and locate the fuse box near the battery.
-
Remove the Fuse Box Cover: Depending on the design, the cover might be secured with clips, screws, or just be snapped on. Carefully remove the cover to access the fuses.
-
Remove the Fuse: Use a fuse puller tool or a pair of needle-nose pliers to grip and pull out the fuse. Pull straight out with gentle, even pressure to avoid damaging the fuse or its housing.
-
Inspect the Fuse: Examine the fuse visually. If the wire inside is broken or discolored, it’s likely blown and needs replacement.
-
Insert the New Fuse: Take the new fuse and carefully insert it into the slot previously occupied by the old fuse. Make sure it fits securely and is seated properly.
-
Replace the Fuse Box Cover: Once you’ve replaced the fuse, put the fuse box cover back on securely, ensuring all clips or screws are fastened properly.
-
Test the Component: After replacing the fuse, turn the ignition to the accessory position (without starting the engine) and test the component to ensure it’s functioning correctly.
Tips:
- Keep spare fuses of various amperages in your vehicle in case of emergencies.
- Handle fuses gently to avoid damaging them or the fuse box.
FAQs
Use a multimeter to verify continuity or visually inspect the fuse for any broken wires inside.
The fuse box is often found on the driver’s side under the dashboard or in the engine compartment.
No, in order to protect your car’s electrical system, you should always replace a blown fuse with one that has the same amperage rating.
A flashlight and a fuse puller or needle-nose pliers are basic tools. For testing, a multimeter can also be useful.
Grip the fuse firmly with needle nose pliers or a fuse puller, then pull it straight out.
As an alternative, needle nose pliers can be used; however, take care not to harm the fuse or any nearby components.
Depending on how the impacted circuit operates. Some might not be necessary for safe driving, while others definitely are.
Fuses can blow for a number of reasons, but they don’t do so very often. If it occurs frequently, there might be a problem that needs to be addressed.
It is true that a blown fuse has the potential to cause problems with related components as well as malfunctions in the corresponding electrical system.
Check the fuse visually for a broken wire or use a multimeter to measure continuity.
Before working on fuses, always disconnect the battery. Also, only swap out fuses for ones with the same amperage rating.
It’s advisable to seek professional assistance as there might be an underlying issue with the electrical system.
No, it is best to avoid using higher amperage fuses as they may cause damage to the electrical system. Use the designated amperage rating at all times.
