The Kona Electric is a compact crossover SUV produced by South Korean automaker Hyundai. Introduced in June 2017, the vehicle went on sale in Western Europe in late 2017. It is marketed as the Hyundai Kauai in Portugal and as the Hyundai Encino in China. This guide provides comprehensive fuse box diagrams and relay panel layouts for the first-generation Hyundai Kona EV (OS chassis code) across model years 2018, 2019, 2020, 2021, 2022, and 2023.
Below you will find the locations, diagrams, and photos of all power distribution centers. The fuses controlling the 12V auxiliary power outlets (“cigarette lighter” sockets) are specifically highlighted.
In the engine compartment
The engine compartment fuse box is located adjacent to the 12V auxiliary battery. Unclip and remove the protective plastic cover to access the fuses.
