Additional Notes

  • All transfer case configurations across the Lexus RX XU30 AWD lineup share a uniform fluid capacity of 0.9 liter, which is consistent with a service fill rather than a full overhaul or dry-fill volume.
  • The Canadian-market RX 330 AWD saw a change interval revision between model years: the 2004-2005 specification calls for a fluid change at 32,000 km, while the 2006 specification extends that interval to 64,000 km under normal use conditions.
  • The Canadian-market RX 350 AWD (2007-2009) carries the same 64,000 km change interval established for the 2006 RX 330, paired with a 16,000 km check interval under normal use.
  • USA-market RX 330 AWD specifications for 2004-2005 separate normal and severe use into distinct service actions: normal use calls for a fluid check at 15,000 miles or 18 months, while severe use triggers an actual fluid change at the same 15,000-mile or 18-month interval.
  • The same normal/severe split seen in the 2004-2005 USA specifications carries forward unchanged into the 2006 USA-market RX 330 AWD, with both the check and change thresholds remaining at 15,000 miles or 18 months.
  • USA-market RX 350 AWD (2007-2009) specifications list only a normal-use check interval of 15,000 miles or 18 months, mirroring the structure of the USA RX 330 normal-use entries rather than the Canadian format that explicitly states a change interval.
  • The Canadian specifications consistently express service intervals in kilometers with two distinct thresholds — a check interval and a change interval — whereas USA specifications use a combined mileage and time threshold of 15,000 miles or 18 months, reflecting different regional service schedule formats.
  • Across all model years and markets covered, the transfer case is identified as an automatic transferbox type, which distinguishes the fluid service requirements from manually shifted transfer cases that may use different fluid types or intervals.
