Additional Notes

  • All capacity figures across every configuration are classified as service fill values, meaning the specified liters represent the amount of fluid used during a partial drain-and-refill service rather than a complete overhaul of the transaxle.
  • The Lexus RX 350, in both AWD and FWD configurations, carries a 7.1-liter service fill capacity for the automatic transaxle, applying equally to Canadian and US market variants starting from 2022.
  • The RX 500h Hybrid AWD carries a 6.4-liter service fill capacity, which is 0.7 liters less than the 7.1-liter figure specified for the RX 350 configurations.
  • Canadian-market RX 350 variants, both AWD and FWD, follow a fluid check interval of every 8,000 km or 6 months under normal use conditions.
  • US-market RX 350 variants, both AWD and FWD, follow a fluid check interval of every 30,000 miles or 36 months under normal use conditions, which is a considerably longer distance-based interval than the Canadian specification.
  • Under severe use conditions, US-market RX 350 AWD and FWD configurations require a fluid change at 60,000 miles or 72 months, a distinction from the normal use schedule, which specifies only a check rather than a full change.
  • The RX 500h Hybrid AWD in the US market follows the same interval structure as the RX 350 US variants: 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 conditions.
  • No Canadian-market specifications are listed for the RX 500h Hybrid AWD, whereas both AWD and FWD variants of the RX 350 have Canadian entries with their own distinct kilometer-based intervals.
