FUSES
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 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 HYUNDAI dealer.
Information
Four kinds of fuses are used : blade type for lower amperage rating, cartridge type/Multi fuse/Battery fuse terminal 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 HYUNDAI dealer.
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 digital 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.

CAUTION
- 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 in side, possibly causing a malfunction with the electrical system.

FAQs
Inspect the fuse box for a visibly damaged or broken fuse, or use a multimeter to check for continuity.
The fuse box is typically located in accessible areas, such as the driver’s side dashboard or the engine compartment.
Basic tools like a fuse puller or needle-nose pliers are often sufficient for safely removing and replacing fuses.
It’s crucial to use a fuse with the same amperage rating as the one being replaced to avoid electrical issues.
Some vehicles come with spare fuses stored in the fuse box or included in the owner’s manual pouch.
Generally, there’s no specific order for replacing fuses; however, it’s recommended to start with the one related to the specific issue.
Common reasons include electrical overloads, short circuits, or issues with specific components like lights or accessories.
Before replacing a fuse, ensure the vehicle is turned off, and if applicable, disconnect the battery to prevent electrical shocks.
Use a multimeter to check for continuity, or replace the fuse with a known good one and see if the issue persists.
Yes, while often a simple fix, a blown fuse can indicate an underlying issue, especially if it happens repeatedly.
Fuses associated with high-use components like headlights or power windows may be more prone to blowing.
If unsure or if the issue persists, seeking professional assistance is recommended to avoid potential electrical problems.
Regularly inspect fuses during routine maintenance or whenever you encounter electrical issues, and replace them as needed.
