The CLA-Class Coupe made its debut in January 2013. Externally, it resembles a smaller CLS. It is especially noticeable on the rear part of the body, as well as the doors. But if you look from the front, you can see that the "faces" of the models are different. The platforms are also different: the larger CLS is based on the E-class, while the compact CLA shares a platform with the A-Class hatchback. In this article, we will take a detailed look at the fuse box diagrams for the Mercedes CLA-Class C117 / X117 (1st Gen; CLA180, CLA200, CLA220, CLA250, CLA45): 2013, 2014, 2015, 2015, 2016, 2016, 2017, 2018, 2019, 2020 years of manufacture.
Here you will find the locations and photos of distribution boxes. The fuses responsible for the “Cigarette lighter” and “Fuel Pump” are highlighted in bold.
In the engine compartment
The distribution box is located on the right side of the underhood.
In order to access it, it is necessary to remove the protective cover by releasing two locks.
