Additional Notes

  • The C5 Aircross 1.2 PureTech 130 with HNS transmission, starting from 2018, carries a service fill capacity of 1.7 liters for its manual transaxle under normal use conditions.
  • A service fill capacity reflects the amount of fluid required when changing fluid in an already-assembled unit, as opposed to a dry fill, which accounts for a completely drained or new assembly with no residual fluid.
  • The 1.5 BlueHDi 130 with YHZ transmission, starting from 2018, lists four distinct capacity values for its manual transaxle, separating dry fill and service fill figures and further dividing each by whether fins are present or absent in the unit.
  • Fins in a transmission housing refer to external cooling fins that increase surface area for heat dissipation. Units built with fins have a different internal volume than those without, which accounts for the capacity differences seen in the YHZ specifications.
  • For the YHZ manual transaxle with fins, the dry fill capacity is 2.2 liters, while the service fill drops to 1.9 liters, reflecting the volume of fluid that remains in the unit after draining.
  • For the YHZ manual transaxle without fins, the dry fill capacity rises to 2.9 liters and the service fill to 2.6 liters, indicating a larger internal volume in the finless housing variant.
  • The 1.5 BlueHDi 130 YHZ transaxle is designated as filled for life, meaning no periodic fluid change interval is specified and the factory fill is intended to last the operational life of the unit under that use condition.
  • The 1.2 PureTech 130 HNS transaxle, by contrast, carries a normal use condition, which is associated with a defined service fill capacity of 1.7 liters rather than a lifetime fill designation.
