Additional Notes

  • The Lexus RX 350 AWD rear differential carries a service fill capacity of 0.5 liter, a figure that reflects a partial drain-and-refill rather than a complete overhaul volume.
  • For the RX 350 AWD in Canada under normal use, the rear differential fluid interval is a check at 8,000 km or 6 months, while the U.S. specification extends that same check interval to 15,000 miles or 18 months.
  • Under severe use conditions, the U.S.-market RX 350 AWD rear differential fluid moves from a check to an actual change at 15,000 miles or 18 months, keeping the mileage and time threshold identical to the normal-use check interval but requiring a full fluid replacement instead.
  • The RX 350h Hybrid AWD rear differential, which also houses the electric motor, holds 1.7 liters of fluid, more than three times the 0.5-liter service fill of the non-hybrid RX 350 AWD rear differential.
  • Under normal use, the RX 350h Hybrid AWD rear differential and electric motor fluid is scheduled for a check at 30,000 miles or 36 months, a notably longer interval than the 15,000-mile or 18-month check on the non-hybrid RX 350 AWD.
  • Under severe use, the RX 350h Hybrid AWD rear differential and electric motor fluid requires a change at 60,000 miles or 72 months, doubling the normal-use check interval in both mileage and time.
  • The RX 500h Hybrid AWD rear differential and electric motor assembly holds 3.1 liters of fluid, the largest rear differential capacity among the configurations listed and nearly double the 1.7-liter figure of the RX 350h Hybrid AWD.
  • The RX 500h Hybrid AWD shares the same interval structure as the RX 350h Hybrid AWD: a check at 30,000 miles or 36 months under normal use, and a change at 60,000 miles or 72 months under severe use, despite the substantially larger fluid capacity.
