The CX-5 is a compact crossover SUV produced by Mazda since 2012. Replacing the Tribute and the slightly larger CX-7, it was the first Mazda model to feature the brand’s “Kodo” design language and the full suite of Skyactiv technologies. This article provides detailed fuse box diagrams and relay panel layouts for the first-generation Mazda CX-5 (chassis KE), covering model years 2011 through 2017.
Below you will find power distribution box locations, photos, and circuit assignments. Fuses for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold text.
