Fuses and Relays
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.

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.

5. Pull the suspected fuse straight out. Use the removal tool provided in the engine compartment fuse panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are provided in the engine compartment fuse panel.
7. 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 other electrical components do not work and the fuses are undamaged, check the fuse panel in the engine compartment. If a fuse is blown, it must be replaced with the same rating.
If the headlamp, turn signal lamp, tail lamp, interior lamp doesn’t work and the fuses are undamaged, consult an authorized HYUNDAI dealer.
