FUSES
A vehicle’s electrical system is protected from electrical overload damage by fuses. This vehicle has 2 fuse panels, one located in the driver’s side panel bolster, the other in the engine 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. If the electrical system does not work, first check the driver’s side fuse panel. Before replacing a blown fuse, move to safe place, turn off the engine and all electric devices, and 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. Four kinds of fuses are used: blade type for lower amperage rating, cartridge type, multi fuse and battery fuse terminal (BFT) for higher amperage ratings.
NOTICE
The actual fuse/relay panel label may differ from the equipped items.
WARNING – Fuse replacement
- Never replace a fuse with anything but another fuse of the same rating.
- A higher capacity fuse could cause damage and possibly a fire.
- Never install a wire or aluminium foil instead of the proper fuse – even as a temporary repair. It may cause extensive wiring damage and a possible 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.
- When replacing an open fuse or relay with a new one, make sure the new fuse or relay fits tightly into the clips. The incomplete fastening fuse or relay may cause the vehicle wiring and electric systems damage and a possible fire.
- Do not remove fuses, relays and terminals fastened with bolts or nuts. The fuses, relays and terminals may be fastened incompletely, and it may cause a possible fire. If fuses, relays and terminals fastened with bolts or nuts are open, consult with an authorized HYUNDAI dealer.
- Do not input any other objects except fuses or relays into fuse/relay terminals such as a driver or wiring. It may cause contact failure and system malfunction.
Instrument panel fuse replacement
- Turn the ignition switch and all other switches off.
- Open the fuse panel cover.
- 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. If you do not have a spare, 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
Your vehicle is equipped with a memory fuse to prevent battery discharge if your vehicle is parked without being operated for prolonged periods. Use the following procedures before parking the vehicle for prolonged periods.
- Turn off the engine.
- Turn off the headlights and tail lights.
- Open the driver’s side panel cover and pull up the memory fuse.
✽ NOTICE
- If the memory fuse is pulled up from the fuse panel, the warning chime, audio, clock and interior lamps, etc., will not operate. Some items must be reset after replacement. Refer to “Battery” in this section.
- Even though the memory fuse is pulled up, the battery can still be discharged by operation of the headlights or other electrical devices.
Engine compartment fuse replacement
- Turn the ignition switch and all other switches off.
- Remove the fuse panel cover by pressing the tab 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
After checking the fuse panel in the engine compartment, securely install the fuse panel cover. If not, electrical failures may occur from water contact.
Main fuse
Electrical equipment are not working even though inner panel and engine compartment fuses are not blown, or many of these are not working at the same time, it may has blown the main fuse(Battery Fuse Terminal type) inside of the battery(+) cap. If the main fuse is blown, consult an authorized HYUNDAI dealer.
CAUTION
After checking the main fuse, install the cover securely when you close the cover, check the locking sound. If not, electrical failures may occur from water leaking in.
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 on the right side in the engine compartment.
- 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 multi fuse is blown, consult an authorized HYUNDAI dealer.
