Additional Notes

  • The Toyota Sienna XL40 in AWD hybrid form carries a rear differential fluid capacity of 1.7 liters across all listed configurations, a figure that reflects a service fill volume for the electric motor-driven rear differential unit rather than a full overhaul quantity.
  • The 1.7-liter capacity applies specifically to the rear differential associated with the electric motor, a component that is distinct from a conventional mechanical rear axle and is present only on AWD hybrid variants of the Sienna XL40.
  • Under normal use conditions, the rear differential fluid interval for the 2020-2021 Sienna 2.5 AWD hybrid is a check at 30,000 miles or 36 months, whichever comes first, rather than a full fluid change.
  • Under severe use conditions, the same 2020-2021 Sienna 2.5 AWD hybrid rear differential calls for a fluid change at 60,000 miles or 72 months, doubling the mileage and time threshold compared to the normal-use check interval.
  • The Sienna 2.5 Hybrid AWD configuration with a starting year of 2021 shares the identical 1.7-liter rear differential capacity and the same interval structure as the 2020-2021 entry, with a normal-use check at 30,000 miles or 36 months.
  • For the 2021-start Sienna 2.5 Hybrid AWD under severe conditions, the rear differential fluid change interval is set at 60,000 miles or 72 months, consistent with the severe-use specification listed for the 2020-2021 variant.
