Additional Notes

  • The brake fluid capacity range of 1.4–2.25 liters across all Mercedes-Benz CLS-Class C219 variants reflects the variable volume present in a hydraulic brake system with ABS. The lower figure represents the minimum fluid level in the reservoir, while the upper figure accounts for the full system volume including ABS hydraulic unit lines and the master cylinder circuit.
  • A 24-month change interval applies uniformly across all C219 configurations under normal use conditions. Brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere over time, which lowers its boiling point and can compromise braking performance. Time-based replacement rather than mileage-based replacement is standard practice for this reason.
  • The CLS 500 (219.375) and CLS 55 AMG Kompressor (219.376) share identical brake fluid capacity and change interval specifications for the 2004-2006 model years, despite the performance difference between the naturally aspirated V8 and the supercharged AMG variant.
  • The CLS 550 (219.372) carries the same 1.4–2.25 liter capacity range and 24-month interval across both the 2006-2007 and 2007-2010 production periods, indicating no revision to brake system fluid specifications between those two sub-ranges.
  • The CLS 63 AMG (219.377) likewise maintains consistent brake fluid specifications across its 2006-2007 and 2007-2010 periods. Despite the high-performance nature of the 63 AMG, the normal-use interval of 24 months remains unchanged relative to the standard CLS variants.
