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.
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 the cover-up. When the blade-type fuse is disconnected, remove it by using the clip designed for changing fuses located in the engine compartment fuse box. Upon removal, securely insert a reserve fuse of the same rating.
-
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 Kia dealer.
CAUTION
After checking the fuse panel in the engine compartment, securely install the fuse panel cover through the audible clicking sound.
If not, electrical failures may occur from water contact.
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 nuts shown in the picture above.
- Replace the fuse with a new one of the same rating.
- Reverse these steps to reinstall the multi-fuse.

How to replace the 2018 Kia RIO Fuse
Here are general steps to guide you:
Materials:
- The new fuse of the correct amperage.
- Fuse puller or needle-nose pliers.
Instructions:
-
Turn off the vehicle:
- Ensure the ignition is turned off, and the key is removed from the ignition.
-
Locate the fuse box:
- The fuse box in the Kia Rio is typically located in one of two places: under the dashboard on the driver’s side or in the engine compartment.
-
Identify the faulty fuse:
- Use the fuse box cover or the owner’s manual to identify which fuse corresponds to the component that is not working.
-
Remove the fuse:
- Use the fuse puller tool or needle-nose pliers to grasp the fuse. Apply gentle, even pressure, and pull the fuse straight out.
-
Inspect the fuse:
- Examine the fuse for any signs of damage, such as a broken filament or discolouration. If the fuse is blown, you will need to replace it.
-
Install the new fuse:
- Take the new fuse of the same amperage rating and push it firmly into the slot where the old fuse was removed.
-
Close the fuse box:
- Ensure that the new fuse is securely in place and that there are no loose wires or debris in the fuse box.
-
Test the component:
- Turn on the ignition and test the component associated with the fuse to ensure it is now functioning properly.
Tips:
- Always use a fuse with the correct amperage rating to prevent electrical issues or damage to the vehicle.
- If a fuse blows repeatedly, it may indicate an underlying electrical problem and professional assistance may be needed.
FAQs
Use a multimeter to check for continuity or look for a visible break in the metal filament inside the fuse.
Depending on the circuit that a blown fuse protects, it can indeed affect multiple components.
Standard instruments consist of a fuse puller or needle-nose pliers and a substitute fuse with the appropriate amperage.
To find out the amperage associated with each fuse, consult the fuse box cover or the handbook for your car.
No, it is not advised to use a higher amperage fuse as this could cause electrical damage.
A few cars come with extra fuses in the fuse box or a special compartment.
Grip the fuse and carefully pull it straight out with a fuse puller or needle-nose pliers.
VThe cause could be a malfunctioning part on the same circuit, wiring problems, or short circuits.
Although it’s not always necessary, disconnecting the battery can help keep people safe from electrical shocks.
Indeed, fuses come in a variety of forms and serve to safeguard distinct circuits.
Once you’ve located the fuse box, it should only take a few minutes to complete.
Depending on how the blown fuse operates. Certain problems could make the car unusable or dangerous to drive.
A blown fuse does frequently have a discolored appearance or a clearly broken filament.
Once you’ve located the fuse box, it should only take a few minutes to complete.
