Additional Notes

  • The Mercedes-Benz CLS-Class C257 transfer case fluid capacity falls within a 0.65–0.68 liter range across both available configurations, which is consistent with a service fill rather than a full overhaul volume.
  • The CLS 450 4MATIC (257.359) carries a transfer case fluid change interval of 77,500 miles under normal use conditions.
  • The CLS 53 AMG 4MATIC+ (257.361) has a notably shorter transfer case fluid change interval of 46,500 miles or 36 months under normal use conditions, whichever comes first.
  • The dual-trigger interval on the CLS 53 AMG 4MATIC+ — combining a mileage threshold with a 36-month time limit — means the fluid is due for replacement based on whichever limit is reached first, regardless of driving frequency.
  • Despite sharing an identical transfer case fluid capacity range of 0.65–0.68 liter, the two configurations differ by more than 31,000 miles in their respective change intervals under the same normal use condition.
  • The CLS 450 4MATIC covers model years 2018-2023, while the CLS 53 AMG 4MATIC+ specifications apply to 2018-2022, representing a one-year difference in the span of each configuration's listed service data.
