Fuses and relays Kia Forte / Cerato 4 (BD; 2018–2023)

Table of Contents

The Kia Forte (marketed as the K3 in South Korea and Vietnam, the Forte K3 or Shuma in China, and the Cerato in South America, Australia, and New Zealand) is a compact car produced by the South Korean automaker since mid-2008. In this article, we take a detailed look at the fuse box diagrams for the Kia Cerato and Forte (fourth generation, BD chassis) for model years 2018, 2019, 2020, 2021, 2022, and 2023. 

Here you will find the locations and layout diagrams for the distribution/junction blocks. Fuses responsible for the “Power Outlet” (Cigarette Lighter) and “Fuel Pump” are highlighted in bold.

Engine Compartment


The main fuse block (1) is located on the left side of the engine compartment. Remove the protective cover to gain access.
