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.
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 is melted or broken.
If the electrical system does not work, first check the driver’s side fuse panel.
WARNING
Never replace a fuse with anything but another fuse of the same rating.
- A higher capacity fuse may 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.
Information
Not all fuse panel descriptions in this manual may be applicable to your vehicle. When you inspect the fuse panel on your vehicle, refer to the fuse panel label. Inside the fuse panel cover, you can find the label describing fuse names and ratings.

Replacing Fuses
Instrument panel fuse replacement
- Turn off the vehicle and all other switches
- 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 tool straight out. Use the removal tool provided in the motor compartment fuses panel cover.
- Check the removed fuse and replace it if it is blown. Spare fuses are provided in the instrument panel fuse panels (or in the motor compartment fuse panel).
- Push in a new fuse of the same rating, and make sure it fits tightly in the clips. If it is not tight, contact 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.
