The Kia Cerato 4th generationwas produced in 2019, 2020, 2021, 2022, 2023 and 2024 and was delivered worldwide with the BD (fourth generation) index. In the USA, Europe and other countries it is also known as Kia Forte and Kia K3. In this material you will find a designation of fuses and relays of the Kia Forte 4 th generationwith fuse box diagrams and their locations. Let’s highlight the cigarette lighter fuse.
The generation of Kia Forte is not suitable?

The design of the blocks and the purpose of their elements may differ from those presented and depend on the year of manufacture and the level of electrical equipment of your car.
Passenger compartment
Inside the car, the fuse box is located at the bottom of the instrument panel on the left side.
To gain access, you must remove the protective cover. The block itself will look something like this.
Check the purpose of the elements with your diagrams on the back of the protective cover.
