The Renault Koleos is a compact crossover SUV manufactured by Renault at its plant in Busan, South Korea. It was the first purpose-built SUV released by the French automaker. This guide provides detailed fuse box diagrams and circuit assignments for the second-generation Renault Koleos (chassis code HC; CMF-CD platform) for model years 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, and 2024.
Below, you will find fuse box locations, photos, and circuit assignment diagrams. Pay special attention to the dedicated fuses for the cigarette lighter (12V power socket) and fuel pump.
In the Engine Compartment
The engine compartment houses five fuse and relay blocks that protect the vehicle’s electrical circuits.
Battery Power Fuses
These high-current fuses are mounted directly on the positive (+) terminal of the battery.
