Frequently Asked Questions
What chassis code does this manual cover?
This manual covers the C218 chassis – the internal Mercedes-Benz designation for the second-generation CLS-Class built from 2011 through 2014. All CLS500 BlueEfficiency body styles on that platform are included.
Is the US-market CLS550 the same as the CLS500 BlueEfficiency?
Yes. Mercedes-Benz badged the same M278 4.7L twin-turbo V8 model as the CLS550 in North America and CLS500 BlueEfficiency in other markets. The underlying C218 platform and powertrain are identical, so this manual applies to both designations.
Are wiring diagrams and fault codes included?
Yes. The manual contains full color-coded wiring schematics, connector pin-out charts, fuse and relay layouts, and diagnostic trouble code (DTC) flowcharts covering engine management, BlueEfficiency systems, COMAND electronics, and body control modules.
What format is the manual?
The manual is delivered as a fully searchable PDF compatible with Windows, Mac, tablets, and smartphones. You can print individual sections as needed, and re-download any time after purchase at no additional cost.
