Additional Notes

  • Across all three configurations in the Lexus RX XU30 (EU) range, the transfer case fluid capacity is 0.9 liter, which is a relatively modest fill volume consistent with a compact transfer box unit rather than a larger mechanical assembly requiring a higher service fill.
  • The RX 300 in its 2003 model year carries a transfer case fluid change interval of 30,000 km or 48 months under normal use conditions, pairing a distance-based threshold with a four-year time limit, whichever comes first.
  • The 2004-2006 RX 300 shares the same 0.9-liter capacity and 30,000 km / 48-month change interval as the 2003 model year, indicating no revision to transfer case service requirements across the full RX 300 production span in the EU market.
  • The RX 350 AWD, covering 2006-2009, also carries a 0.9-liter transfer case fluid capacity with a 30,000 km or 48-month change interval under normal use, matching the figures established for the earlier RX 300 configurations.
  • All three rows are designated for normal use conditions, meaning the 30,000 km and 48-month intervals apply specifically to standard operating environments rather than severe-duty cycles.
  • The 48-month time-based interval functions as an independent trigger alongside the 30,000 km mileage limit, so a vehicle accumulating low annual mileage would still reach a service point at the four-year mark regardless of distance traveled.
  • The transfer case note across all configurations specifies an automatic transferbox, which distinguishes the fluid service context from manually shifted transfer cases that may involve different fluid types or service procedures.
