The CLA-Class coupe debuted in January 2013. Outwardly, it resembles a reduced CLS. This is especially noticeable on the rear of the body, as well as on the doors. But if you look from the front, you can see that the "faces" of the models are different. Platforms are also different: the larger CLS is based on the E-class, while the compact CLA shares the platform with the A-Class hatchback. In this article we analyze in detail the circuit fuse Mercedes-Benz CLA-Class 1st generation (body C117 / x117: CLA180, CLA200, CLA220, CLA250, CLA45 ): 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020 model year.
Here you will find the locations and photos of the fuse blocks. Separately, we note the elements responsible for the cigarette lighter and fuel pump.
In the engine compartment
The block is located on the right side of the engine compartment.
To access it, it is necessary to remove the protective cover by pressing two latches.
