The Omoda C7 entered production in 2025 and is still in production. It is shipped worldwide. In this article, we will describe the Omoda C7 ‘s fuses and relays, including fuse box diagrams, their locations, and photo examples. We will highlight the fuse responsible for the cigarette lighter and USB ports.
The purpose of fuses and relays may differ from those presented and depend on the year of manufacture, the level of electrical equipment and the region of delivery of your vehicle.
Passenger compartment
Inside the car, the fuse and relay box is located at the bottom of the instrument panel behind a plastic protective cover.
Or through the protective cover, if there is one on the panel.
