Additional Notes

  • The Toyota Avalon XX50 rear differential holds 0.5 liter of fluid across all AWD configurations covered in these specifications, which is a compact fill volume consistent with the sealed, compact rear drive units commonly found in transverse-based AWD passenger cars.
  • The 2.5 AWD variant covering model years 2020-2021 shares the same 0.5-liter rear differential capacity as the 3.5 V6 AWD variants, indicating no meaningful volumetric difference between the four-cylinder and six-cylinder drivetrain configurations at the rear differential.
  • Under normal use conditions, the rear differential fluid interval for both the 2.5 AWD and 3.5 V6 AWD is listed as a check at 15,000 miles or 18 months, meaning the fluid level and condition are inspected rather than replaced on that schedule.
  • Under severe use conditions, the same 15,000-mile or 18-month interval triggers a full fluid change rather than an inspection, reflecting the greater thermal and mechanical stress placed on differential fluid in demanding operating environments.
  • The 3.5 V6 AWD (USA) appears across two overlapping year groupings in these specifications: 2019-2021 and 2021-2022. Both groupings carry identical capacity and interval figures for the rear differential under both normal and severe use conditions.
  • The 18-month time component of the service interval functions as a calendar-based ceiling, meaning whichever threshold is reached first, mileage or time, governs when the check or change is due regardless of how the vehicle has been driven.
