The 4th generation Kia Optima was produced in 2015, 2016, 2017, 2018, 2019, 2020. Also known as Kia Magentis. During this time, the car has been restyled. In this publication you will find a designation of the fuses and relays of the Kia Optima JF (Magentis) generation with boxes diagrams, photos and locations. Let’s show the cigarette lighter fuse. In conclusion, we offer for download a complete manual for repair and maintenance.
The purpose of the fuses and relays in the boxes of your Kia Optima 4 may differ from the one presented and depends on the year of manufacture, the level of equipment and the region of delivery. Check the designation with your diagrams on the back of the protective cover.
