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, 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 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.
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.
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, such as the cigarette lighter fuse. 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 in 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.
- 2. 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 HYUNDAI dealer.
CAUTION

LIGHT BULBS
Consult an authorized HYUNDAI dealer to replace most vehicle light bulbs. It is difficult to replace vehicle light bulbs because other parts of the vehicle must be removed before you can get to the bulb. This is especially true for removing the headlamp assembly to get to the bulb(s).
Removing/installing the headlamp assembly can result in damage to the vehicle.
Information
After heavy driving, rain, or washing, headlamp, and trunk lenses could appear frosty. This condition is caused by the temperature difference between the lamp inside and the outside temperature. This is similar to the condensation on your windows inside your vehicle during the rain and does-n’t indicate a problem with your vehicle. If the water leaks into the lamp bulb circuitry, have your vehicle checked by an authorized HYUNDAI dealer.
WARNING
- Before replacing a lamp, depress the foot brake, move the shift lever into P (Park) apply the parking brake, place the ignition switch to the LOCK/OFF position, and take the key with you when leaving the vehicle to avoid sudden movement of the vehicle and to prevent possible electric shock.
- Be aware the bulbs may be hot and may burn your fingers.
FAQs
Fuses are electrical safety devices designed to protect the vehicle’s electrical system from damage caused by excessive current flow. They are crucial for preventing electrical fires and damage to components.
Typically, if a fuse is blown, the component it protects will not function. Additionally, you can visually inspect the fuse to see if the metal strip inside is intact or broken.
In the 2017 Hyundai Elantra, the fuse box is usually located in the engine bay or under the dashboard on the driver’s side.
Yes, replacing a blown fuse is typically a straightforward task that can be done by most car owners. However, if you’re unsure, it’s always best to consult a professional.
Usually, all you need is a fuse puller or a pair of needle-nose pliers to remove the blown fuse and a replacement fuse of the correct amperage.
The amperage rating for each fuse is usually printed on the fuse itself or listed in the owner’s manual. It’s crucial to replace the blown fuse with one of the same amperage to prevent damage to the electrical system.
No, using a fuse with a higher amperage rating can lead to electrical damage or fires. Always use a fuse with the same amperage rating as the blown fuse.
If a replacement fuse blows immediately, it indicates that there may be a short circuit or another underlying issue with the electrical system. In this case, it’s best to have the vehicle inspected by a professional.
It depends on which component the blown fuse is protecting. If it’s a non-essential component, you may still be able to drive the vehicle. However, if it’s a critical component like the headlights or brake lights, it’s best not to drive until the fuse is replaced.
Fuses typically last a long time and may never need to be replaced under normal circumstances. However, they can blow due to electrical faults or overloads.
If you’re having trouble identifying the faulty fuse, or if the issue persists after replacing the fuse, it’s best to consult a professional mechanic who can diagnose and repair the problem.
While there may not be a specific brand recommendation, it’s important to use high-quality fuses from reputable manufacturers to ensure safety and reliability.
While some blown fuses are unavoidable due to electrical faults or overloads, you can minimize the risk by avoiding overloading electrical circuits and promptly addressing any electrical issues that arise. Regular vehicle maintenance can also help prevent blown fuses.
