* Owner's Manual: The most likely and easiest place to start. Your owner's manual should have a section dedicated to fuses and relays, including a diagram showing their locations and what circuits they protect.
* Inside the Fuse Box: There are usually diagrams printed *inside the lid* of the fuse box itself. The CLK430 has multiple fuse boxes (one in the passenger compartment and one in the engine compartment). Check both.
* Online Resources: Websites like Mercedes-Benz forums (search for "2000 CLK430 fuse diagram"), repair manuals websites (like those selling Haynes or Chilton manuals), or online parts catalogs might have diagrams. Be cautious and verify the source is reliable. Always double-check that the diagram matches your specific year and model.
* Mercedes-Benz Dealership: As a last resort, your local Mercedes-Benz dealership service department can provide you with a fuse diagram.
Remember to always disconnect the negative battery terminal before working with fuses or electrical components to prevent short circuits and damage.
