Additional Notes

  • Across all five configurations of the Mercedes-Benz GLE-Class W166 covered in the specifications, the transfer case fluid capacity is listed with two distinct values: 0.5 liter and 1.5 liter, where the larger figure applies specifically to units equipped with a dual range system.
  • The 0.5 liter figure represents the standard transfer case fill volume, while the 1.5 liter capacity reflects the additional fluid demand introduced by the dual range assembly, which mechanically expands the unit's internal components and lubrication requirements.
  • The GLE 350 4MATIC (166.057) and GLE 400 4MATIC (166.056) share identical transfer case fluid capacities across the 2015-2019 model year span, with both the standard 0.5 liter and the dual range 1.5 liter values applying equally to each variant.
  • The GLE 550 4MATIC (166.073) carries the same 0.5 liter and 1.5 liter dual range capacity figures as the other variants, though the model year coverage for the 550 4MATIC runs through 2018 rather than 2019.
  • The GLE 63 AMG (166.074) and GLE 63 S AMG (166.075) follow the same transfer case fluid capacity specifications as the non-AMG variants, with 0.5 liter for the standard unit and 1.5 liter when the dual range configuration is present, across the 2015-2019 range.
  • All five configurations carry a normal use condition designation, meaning the listed capacities are associated with standard operating service rather than a severe-duty or first-change-only service scenario.
  • The three-fold difference between the standard 0.5 liter fill and the 1.5 liter dual range fill underscores how significantly the dual range mechanism increases the internal volume requiring lubrication within the transfer case assembly.
