Additional Notes

  • The Mercedes-Benz CLS-Class C257 front differential capacity is listed at 0.55 liter for both the CLS 450 4MATIC (257.359) and the CLS 53 AMG 4MATIC+ (257.361), and I note that value applies equally to the standard housing and the light alloy housing variant.
  • The front differential's 0.55 liter figure is a relatively small service fill, consistent with the compact integrated front axle differential units commonly found in all-wheel-drive passenger cars rather than larger truck-type axle assemblies.
  • Rear differential capacity for the CLS 450 4MATIC (257.359) is listed across four distinct values — 0.8, 0.9, 1.0, and 1.1 liters — all under normal use conditions, indicating that multiple rear differential unit variants are fitted to the same model designation depending on the specific assembly installed.
  • The same four rear differential capacity values of 0.8, 0.9, 1.0, and 1.1 liters appear identically for the rear-wheel-drive CLS 450 (257.358), confirming that the rear differential hardware variants are shared across the 4MATIC and non-4MATIC configurations of the CLS 450.
  • The CLS 53 AMG 4MATIC+ (257.361) carries the same rear differential capacity spread of 0.8, 0.9, 1.0, and 1.1 liters as the CLS 450 variants, meaning the AMG model does not use a uniquely sized rear differential unit relative to the non-AMG trims in the C257 lineup.
  • All capacity figures across every row are designated for normal use conditions, with no separate severe-use or first-change-only intervals listed for any differential position or model variant in the C257 specifications.
  • The CLS 450 (257.358) rear-wheel-drive variant covers model years 2018-2022, while the CLS 450 4MATIC (257.359) spans 2018-2023, representing a one-year difference in the listed production range between the two CLS 450 configurations.
  • The presence of four separate rear differential capacity entries for a single model variant reflects that the correct fill volume is housing-dependent, and using an incorrect figure during service could result in either underfilling or overfilling the unit.
