Relay Guide: 2018 Genesis G80 Fuses and Fuse Box
A fuse box is a feature of the 2018 Genesis G80 that is essential for controlling and safeguarding the electrical systems of the car. Numerous fuses in the fuse box are intended to break an electrical circuit in the event of a high current or short circuit, protecting the car’s systems from harm. The 2018 Genesis G80’s fuse box is arranged neatly and conveniently inside the car, with each fuse serving a particular purpose in terms of electricity. This covers devices like air conditioning, power windows, lighting, and more. One frequent troubleshooting approach for a non-functioning function on your G80 is to check the relevant fuse in the fuse box.

FUSES
A vehicle’s electrical system is protected from electrical overload damage by fuses. This vehicle has 4 fuse panels, one located in the driver’s side panel bolster, another in the engine compartment, and two others in the trunk compartment. 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 melted or broken. If the electrical system does not work, first check the driver’s side fuse panel. Before replacing a blown fuse, turn the engine and all switches off, and then disconnect the negative battery cable. 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 retailer of Genesis Branded products.
Information
Four kinds of fuses are used: blade type for lower amperage rating, cartridge type/Multi fuse/Fusible link for higher amperage ratings.
WARNING
NEVER replace a fuse with anything but another fuse of the same rating.
- A higher capacity fuse could cause damage and possibly cause a fire.
- Do not install a wire or aluminum foil instead of the proper fuse – even as a temporary repair. It may cause extensive wiring damage and possibly a fire.
NOTICE
Do not use a screwdriver or any other metal object to remove fuses because it may cause a short circuit and damage the system.
Instrument Panel Fuse Replacement
- Turn the engine off.
- Turn all other switches OFF.
- Open the fuse panel cover.
- Refer to the label on the inside of the fuse panel cover to locate the suspected fuse location.
- Pull the suspected fuse straight out. Use the removal tool provided in the engine compartment fuse panel.
- Check the removed fuse; replace it if it is blown. Spare fuses are provided in the instrument panel fuse panels (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 retailer of Genesis Branded products.
In an emergency, if you do not have a spare fuse, use a fuse of the same rating from a circuit you may not need for operating the vehicle. If the headlamps or other electrical components 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 with the same rating.
Fuse switch
Always, place the fuse switch to the ON position. If you move the switch to the OFF position, some items such as the audio system and clock must be reset and the smart key may not work properly.
Information
If the fuse switch is OFF, the above message will appear.
NOTICE
- Always place the fuse switch in the ON position while driving the vehicle.
- Do not move the fuse switch repeatedly. The fuse switch may be damaged.
Engine Compartment Panel Fuse Replacement
- Turn the engine off.
- Turn all other switches OFF.
- Remove the fuse panel cover by pressing the tap and pulling 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 retailer of Genesis Branded products
NOTICE
After checking the fuse box in the engine compartment securely close the fuse box cover inside the engine compartment, until it clicks. If the fuse box is not closed properly, water may leak inside, possibly causing a malfunction with the electrical system.
Main fuse
If the main fuse is blown, it must be removed as follows:
- Turn off the engine.
- Disconnect the negative battery cable.
- Remove the fuse panel cover by pressing the tab and pulling it up.
- 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.
Information
If the main fuse is blown, consult an authorized retailer of Genesis Branded products.
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 fuse panel cover by pressing the tab and pulling it up.
- 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.
Information
If the multi fuse is blown, consult an authorized retailer of Genesis Branded products.
Blade type fuse
Before inspecting a fuse, you should turn OFF the engine as well as the other electric system switches. If a fuse is blown out, remove the blown-out fuse and install a new fuse of the same capacity by using the fuse puller, which is prepared inside the fuse box in the engine compartment. A new fuse may be prepared along with the fuse puller. However, if not, you may temporarily select/use a fuse of the other systems, which do not affect the vehicle operation, such as the audio system.
Cartridge type fuse
Before inspecting a fuse, you should turn OFF the engine as well as the other electric system switches. If a fuse is blown out, remove the blown-out fuse and install a new fuse of the same capacity. Pay extreme caution not to damage the blown-out fuse while removing it.

How to Replace Fuses of Genesis G80
Replacing fuses in a Genesis G80 is a straightforward process. Here’s a detailed guide along with some helpful tips:
-
Locate the Fuse Box: The fuse box in the Genesis G80 is typically located either under the dashboard on the driver’s side or under the hood near the battery. Look for a rectangular or square-shaped black plastic box.
-
Identify the Fuse Box Cover: The fuse box cover may have a diagram indicating which fuses correspond to various components. If there’s no diagram on the cover, you might need to refer to an online resource or use the guidance of a professional.
-
Turn Off the Vehicle: Before beginning any work on the fuses, ensure that the vehicle is completely turned off, and the key is removed from the ignition.
-
Open the Fuse Box Cover: Depending on the model year of your Genesis G80, you may need to press a release latch or simply lift the cover to access the fuses. Some models may have additional covers within the fuse box itself.
-
Determine the Faulty Fuse: If you’re encountering a specific electrical issue, utilize the fuse diagram to identify which fuse corresponds to the malfunctioning component.
-
Remove the Fuse: Use a fuse puller tool if one is available, or carefully grip the fuse with your fingers and pull it straight out. Ensure you do this gently to avoid damaging the fuse or the fuse box.
-
Inspect the Fuse: Visually inspect the fuse to determine if the wire inside is intact. If the wire is broken or there are signs of damage, the fuse requires replacement.
-
Select the Correct Replacement Fuse: Refer to the fuse diagram to determine the correct amperage and type of fuse required for replacement. Using an incorrect fuse can lead to electrical problems or damage to your vehicle.
-
Insert the New Fuse: Carefully insert the new fuse into the slot from which you removed the old one. Ensure that it fits securely and is seated properly.
-
Close the Fuse Box Cover: After replacing the fuse, firmly close the fuse box cover to prevent any dust or moisture from entering the fuse box.
-
Test the Component: Turn the ignition to the accessory position (without starting the engine) and test the component associated with the fuse to verify that it’s functioning correctly.
Tips:
- Keep a variety of spare fuses in your vehicle, covering different amperages, in case of emergencies.
- Periodically inspect your fuses if you notice any electrical issues with your Genesis G80.
- Handle fuses delicately to prevent damage to the fuse box or other components.
- If you’re uncertain about which fuse controls a particular component, consider seeking assistance from a professional mechanic.
FAQs
A fuse is a safety tool used to guard against overcurrents in electrical circuits.
The fuse box is usually either inside the cabin or in the engine compartment.
Depending on the design, you can either remove the screws or press a latch to open the fuse box cover.
A fuse’s amperage rating is usually indicated by its color. For information on the colors and amperage ratings or the cover of the fuse box.
Examine the fuse using a fuse tester or by looking at it. The fuse blows if the metal strip within the fuse breaks.
No, that is not advised. To prevent harming the electrical system, always replace fuses with the same amperage rating.
Fuse blows can be caused by short circuits, overloaded circuits, or defective electrical components.
A thorough list of fuse amperage ratings can be found by looking behind the fuse box.
Usually, all you need is a pair of needle-nose pliers or a fuse puller.
Check your car’s fuses on a regular basis and replace any that blow. It’s a wise procedure to follow throughout standard upkeep.
In order to prevent electrical shock or injury, it is often safer to change fuses with the ignition turned off.
It is advised to have a professional evaluate the area if changing a fuse doesn’t resolve the issue.
