In 2009, the Mercedes-Benz S-Class W221 underwent restyling. His model year presentation took place in April in Stuttgart. In this material, we will analyze in detail the fuse diagrams of the fifth generation Mercedes S-class (W221 / C216: S350, S450, S500, S65 AMG, S63) in the restyling of 2009, 2010, 2011, 2012, 2013 model year.
Here you will find the locations and photos of the mounting blocks. Separately, we note the fuses responsible for the cigarette lighter and fuel pump.
In the trunk
Access is from the passenger compartment. The armrest needs to be folded back. Then remove the trim and the plastic cover.
