Additional Notes

  • The Lexus RX 350 AWD transfer case holds 0.45 liter as a service fill figure, meaning the capacity reflects the amount of fluid added during a routine top-up or partial drain procedure rather than a complete overhaul refill.
  • The Canadian market RX 350 AWD transfer case inspection interval is set at 8,000 km or 6 months under normal use conditions, reflecting a metric-based service schedule.
  • The US market RX 350 AWD transfer case carries a check interval of 15,000 miles or 18 months under normal use conditions, which is a notably longer distance interval compared to the Canadian specification.
  • Under severe use conditions, the US market RX 350 AWD transfer case moves from a fluid check requirement to an actual fluid change at the same 15,000-mile or 18-month interval, making the service action more involved than the normal-use equivalent.
  • The 0.45-liter service fill capacity is consistent across both the Canadian and US market RX 350 AWD configurations, regardless of whether the service action is a check or a change.
