The premiere of the S-Class in the back of the W222 took place in May 2013. When creating the interior, its long-wheelbase version was taken as a basis, so that the maximum comfort on the back sofa was ensured. In 2017, the car went through restyling. In this material, we will analyze in detail the fuse diagrams of the sixth generation Mercedes S-class (W222 / C217: S300, S350, S400, S450, S500, S550, S560, S600, S650, S63, S65) 2013, 2014, 2015, 2016, 2017, 2018 and 2019, 2020 release.
Here you will find the locations and photos of the fuse blocks. Separately, we note the elements responsible for the cigarette lighter.
In the luggage compartment
The unit is located on the right side of the trunk, behind the trim.
