Additional Notes

  • The rear electric drive differential on the Toyota Prius Hybrid AWD (ZVW55) carries a capacity of 1.2-1.3 liters for the 2020-2021 model year, while the 2021-2022 entries list a fixed 1.2 liters. A capacity expressed as a range typically reflects variation between a drain-and-fill service and a full overhaul or housing replacement, whereas a single fixed value represents a standard service fill.
  • For the 2021-2022 ZVW55 under normal use conditions, the rear differential fluid is subject to a check interval of 48 months or 60,000 km, with no change interval specified for that condition.
  • Under severe use conditions for the 2021-2022 ZVW55, the rear differential fluid check interval tightens to 36 months or 45,000 km, and a fluid change is required at 72 months or 90,000 km. Severe use intervals are generally applied when the vehicle operates under more demanding conditions such as frequent towing, extreme temperatures, or repeated short trips.
  • The 2020-2021 ZVW55 row carries no interval data, only a capacity figure, meaning no check or change schedule is associated with that particular entry in the specifications.
  • The rear differential fluid capacity of 1.2 liters is consistent across both the normal and severe use rows for the 2021-2022 ZVW55, indicating the fill volume does not vary by service condition, only the timing of service actions does.
