Additional Notes

  • The Mercedes-Benz CLS-Class C218/X218 transfer case fluid capacity is specified as a range of 0.65 to 0.68 liter across all listed 4MATIC variants. A capacity expressed as a range rather than a fixed value reflects the tolerance built into the fill procedure, where the correct level is confirmed by the fluid reaching the fill plug opening rather than by measuring a precise volume.
  • The CLS 250 d 4MATIC (218.397/997), covering model years 2015-2018, shares the same 0.65-0.68 liter transfer case capacity and 125,000 km / 60-month service interval as the larger-displacement diesel and petrol variants in the same generation.
  • The CLS 350 BlueTEC 4MATIC (218.394) from 2013-2015 and the CLS 350 d 4MATIC (218.394/994) from 2015-2018 carry identical transfer case specifications despite the naming change between model years, with both showing a 0.65-0.68 liter fill range and a 125,000 km / 60-month change interval under normal use conditions.
  • The 60-month time limit on the transfer case fluid change interval means the fluid is due for replacement at whichever threshold arrives first, either 125,000 km of driving or five years of elapsed time, regardless of mileage accumulated.
  • The CLS 500 4MATIC BlueEFFICIENCY (218.391/991), produced from 2012-2016, and the CLS 550 4MATIC BlueEFFICIENCY (218.391/991), produced from 2012-2015, share the same chassis code designation and identical transfer case fluid specifications, reflecting a common transfer case unit across both V8 output variants.
  • All five listed configurations carry a normal use condition designation for the transfer case fluid service interval. In fluid service terminology, a normal use classification typically applies to standard on-road driving as opposed to severe duty cycles involving frequent towing, off-road operation, or extreme temperature exposure.
  • The transfer case fluid volume of under one liter across all listed variants is consistent with the compact, single-speed transfer cases commonly used in passenger car-based all-wheel-drive systems, which differ substantially in size and fluid capacity from truck-oriented transfer cases with selectable ranges.
