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, 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.
NOTICE
Three kinds of fuses are used: blade type for lower amperage rating, cartridge type, and 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 a fire.
- Do not install a wire or aluminium 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 fuses panel.
- Remove and check the suspected 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 headlights 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.
Memory fuse
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 remote key (or smart key) may not work properly.
CAUTION
Always place the fuse switch in the ON position while driving the vehicle.
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.
- Remove and check the suspected 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.
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 tap 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.
✽ NOTICE
If the main fuse is blown, consult an authorized HYUNDAI 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 fuse panel cover by pressing the tap and pulling up.
- Remove the bolts shown in the picture above.
- Replace the fuse with a new one of the same rating.
- Reinstall in the reverse order of removal.
✽ NOTICE
If the multi fuse is blown, consult an authorized HYUNDAI dealer.
