Fuses and relays Mercedes CLS-Class (C219; 2004 - 2010)

The CLS debuted at the 2004 New York Auto Show. The car is positioned as a four-door coupe, in fact, it is a fastback sedan with a rear-wheel drive layout. The car was designed by American designer Michael Fink. In this material, we will analyze in detail the fuse circuits for the Mercedes CLS class first generation (body 219: CLS280, CLS300, CLS320, CLS350, CLS500, CLS55 ): 2004, 2005, 2006, 2007, 2008, 2009, 2010 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.
