In 2009, the Mercedes-Benz S-Class W221 underwent a restyling. Its presentation of the model year took place in April in Stuttgart. In this article we will understand in detail fuse box diagrams Mercedes W221 / C216 (5th Gen; S-Class: S350, S450, S500, S65 AMG, S63) in restyling 2009, 2010, 2011, 2012, 2013 years of manufacture.
Here you will find the locations and photos of the mounting blocks. Also, we will separately mark the fuses responsible for the cigarette lighter and the fuel pump.
In the trunk
Access is from the passenger compartment. It is necessary to fold down the armrest. Then remove the trim and the plastic cover.
