Additional Notes

  • The Toyota Prius XW50 AWD-e rear electric motor differential holds 1.2 liters of fluid across all listed configurations, a figure that reflects a service fill capacity for a compact rear-drive unit rather than a full overhaul volume.
  • The 1.2-liter capacity remains consistent across both the 2018-2021 and 2021-2022 model year ranges, with no variation tied to the year of production within the AWD-e lineup.
  • Canadian-market AWD-e specifications list only a capacity value under normal use conditions, without an associated change interval in the provided data.
  • US-market AWD-e specifications apply a severe use condition, under which a fluid change interval of 60,000 miles or 72 months is specified for the rear differential.
  • A 72-month interval corresponds to six years of service, meaning the mileage and time limits run concurrently, with whichever threshold is reached first typically governing the service point.
  • The severe use designation in the US-market rows indicates the interval was established for more demanding operating conditions, such as frequent towing, off-road use, or repeated short-trip driving cycles.
  • The 2021-2022 US-market configuration carries the same 60,000-mile and 72-month severe-use interval as the 2018-2021 range, indicating no revision to the change schedule between those two overlapping year spans.
