Toyota Grand Highlander (USA / CAN)

Differential fluid capacity & service interval

Toyota Grand Highlander (USA / CAN) differential fluid capacity ranges from 0,45 to 3 liters. Service intervals include checks at 15000 miles/ 18 months and 30000 miles/ 36 months, and changes at 15000 miles/ 18 months, 30000 miles/ 36 months, and 60000 miles/ 72 months. The data covers 6 configurations.

Additional Notes

  • The Toyota Grand Highlander carries three distinct rear differential fluid capacities across its AWD configurations: 0.45-0.55 liter for the 2.4 AWD, 1.7 liters for the 2.5 AWD Hybrid, and 3 liters for the 2.4 AWD Hybrid MAX. A capacity expressed as a range, as seen in the 2.4 AWD, typically reflects a service fill tolerance rather than a fixed overhaul volume.
  • The 3-liter capacity of the 2.4 AWD Hybrid MAX rear electric drive differential is notably larger than the other two configurations. Electric drive differentials often integrate motor and reduction gear components within the same housing, which accounts for the substantially higher fluid volume.
  • Under normal use conditions, the 2.4 AWD rear differential follows a two-stage service schedule: a fluid check at 15,000 miles or 18 months, followed by a fluid change at 30,000 miles or 36 months. The check interval serves as an intermediate inspection point before the full drain-and-fill service.
  • Under severe use conditions, the 2.4 AWD rear differential change interval shortens to 15,000 miles or 18 months, which matches the normal-use check interval. No separate check interval is listed for severe use, meaning the change itself replaces the inspection step.
  • Both hybrid configurations, the 2.5 AWD Hybrid and the 2.4 AWD Hybrid MAX, share the same check interval of 30,000 miles or 36 months under both normal and severe use conditions. The check schedule does not differentiate between the two driving conditions for either hybrid model.
  • Under severe use, both hybrid configurations add a fluid change at 60,000 miles or 72 months. Under normal use, no change interval is specified for either hybrid rear electric drive differential, only the periodic check at 30,000 miles or 36 months.
  • The 2.5 AWD Hybrid rear electric drive differential holds 1.7 liters, placing its capacity between the compact 0.45-0.55 liter range of the 2.4 AWD and the 3-liter volume of the 2.4 AWD Hybrid MAX. Each powertrain variant therefore requires a different fluid quantity at service time.
