Additional Notes

  • The transfer case fluid capacity across all listed Lexus NX AZ20 AWD configurations is 0.45 liter, applying equally to both the NX 250 AWD and NX 350 AWD variants in both USA and Canadian markets.
  • The NX 350 AWD rows explicitly label the 0.45 liter figure as a service fill, meaning the quantity reflects a partial fluid exchange rather than a full drain and refill of the transfer case from empty.
  • The NX 250 AWD rows carry no service fill designation on the 0.45 liter capacity, which distinguishes how the specification is presented compared to the NX 350 AWD entries.
  • Canadian market intervals for both the NX 250 AWD and NX 350 AWD are expressed in kilometers and months, with a check interval of 8,000 km or 6 months under normal use conditions.
  • USA market intervals are expressed in miles and months, with a check interval of 15,000 miles or 18 months under normal use conditions for both the NX 250 AWD and NX 350 AWD.
  • Under severe use conditions, the USA-market NX 250 AWD specifies a fluid change at 15,000 miles or 18 months, whereas the same interval under normal use only calls for a check rather than a change.
  • The same severe-use pattern applies to the USA-market NX 350 AWD, where the 15,000-mile or 18-month interval triggers a fluid change rather than a check, at the same 0.45 liter service fill capacity.
  • No severe-use interval is listed for either the NX 250 AWD or NX 350 AWD in the Canadian market, where only normal-use check intervals appear in the specifications.
  • The NX 350 AWD entries begin from 2022 in both markets, while the NX 250 AWD entries begin from 2021, reflecting a one-year offset in the starting model year between the two variants.
