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.
