Step-by-Step Air Filter Replacement

Follow these simple steps to replace your CLS’s air filter:

  1. Open the hood: Release the hood latch and prop the hood open securely.
  2. Locate the air filter housing: It is typically a black plastic box situated near the engine, often secured with clips or screws.
  3. Remove the housing cover: Use a screwdriver or socket wrench to undo any fasteners and carefully lift the cover.
  4. Take out the old air filter: Note its orientation before removing it to ensure proper installation of the new one.
  5. Clean the housing: Wipe out any dirt or debris inside the housing with a rag or use compressed air for better results.
  6. Install the new filter: Place the new filter into the housing in the same orientation as the old one.
  7. Reassemble the housing: Replace the cover and secure it with screws or clips.
  8. Close the hood: Make sure it’s properly latched before driving.

Regularly changing your air filter, typically every 15,000 to 30,000 miles, can improve engine longevity and maintain your CLS sedan’s performance. Always consult your owner’s manual for specific recommendations related to your model year.
