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 ratings. If the replacement fuse blows, this indicates an electrical problem. Avoid using the system involved and immediately consult an authorized HYUNDAI dealer.

Information
Three kinds of fuses are used: blade type for lower amperage ratings, 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 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

1. Turn the engine off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside of the fuse panel cover to locate the suspected fuse location.
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 instrument panel fuse panels (or 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, 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.
• Do not move the transportation fuse switch repeatedly. The fuse switch may be damaged.

Engine Compartment Panel Fuse Replacement

1. Turn the engine off.
2. Turn all other switches OFF.
3. Remove the fuse panel cover by pressing the tap and pulling up.
4. 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.
5. 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:

1. Turn off the engine.
2. Disconnect the negative battery cable.
3. Remove the fuse panel cover by pressing the tab and pulling it up.
4. Remove the nuts shown in the picture above.
5. Replace the fuse with a new one of the same rating.
6. Reinstall in the reverse order of removal.

Information
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:

1. Turn off the engine.
2. Disconnect the negative battery cable.
3. Remove the fuse panel cover by pressing the tab and pulling it up.
4. Remove the nuts shown in the picture above.
5. Replace the fuse with a new one of the same rating.
6. Reinstall in the reverse order of removal.

Information
If the multi fuse is blown, consult an authorized HYUNDAI dealer.

How to Replace Fuses of Hyundai Tucson

Replacing fuses in a Hyundai Tucson is a relatively straightforward process. Here’s a detailed guide along with some tips:

1. Locate the Fuse Box: The fuse box in the Hyundai Tucson is typically located in one of two places: either in the engine bay or inside the cabin, often beneath the dashboard on the driver’s side.

2. Turn Off the Vehicle: Before replacing any fuses, ensure that the vehicle’s ignition is turned off, and the key is removed from the ignition switch to prevent any electrical mishaps.

3. Select a Replacement Fuse: Check the amperage rating printed on the blown fuse and select a replacement fuse with the exact same amperage rating. Using a fuse with a different amperage rating could cause electrical issues or damage to your vehicle.

4. Remove the Blown Fuse: Once you’ve identified the blown fuse and selected a replacement, use a fuse puller tool or a pair of needle-nose pliers to grip the blown fuse firmly. Pull the fuse straight out of its socket, being careful not to damage the fuse box or adjacent fuses in the process.

5. Insert the Replacement Fuse: Take the replacement fuse and insert it into the empty socket in the fuse box. Make sure the fuse is seated securely and fully inserted into the socket to ensure proper electrical connection.

6. Check for Proper Fit: Double-check that the replacement fuse fits snugly into the socket and is of the correct amperage rating. It should not be loose or protruding from the socket.

7. Replace the Fuse Box Cover: Once you’ve replaced the blown fuse with a new one, carefully replace the fuse box cover and ensure that it is securely fastened. This helps to prevent water or debris from entering the fuse box.

8. Test the Circuit: Turn the ignition key to the accessory position or start the vehicle to test the circuit associated with the replaced fuse. Verify that the electrical component or system is functioning properly.

9. Dispose of the Blown Fuse: Dispose of the blown fuse properly. You can keep it as a spare in case of future emergencies or dispose of it according to local regulations for electronic waste.

Tips:

• • Use the Fuse Puller Tool: If your Hyundai Tucson comes with a fuse puller tool, use it to remove the blown fuse. This can help prevent damage to the fuse or the fuse box.
  • Check Other Fuses: If you find one blown fuse, it’s a good idea to check the surrounding fuses as well. Sometimes, multiple fuses may blow simultaneously due to the same issue.
  • Keep Spare Fuses: It’s wise to keep a set of spare fuses of various amperage ratings in your vehicle’s glove compartment for quick replacement in case of emergencies.
