Additional Notes
- The Lexus RX XU30 (EU) rear differential holds 0.9 liter across the RX 300 (2003-2006) and RX 350 AWD (2006-2009), with a change interval of 30,000 km or 48 months under normal use conditions.
- The RX 400h AWD rear electric drive differential carries a notably larger capacity of 1.8 liters, double that of the conventional RX 300 and RX 350 AWD units, reflecting the additional fluid volume required by the electrically driven rear axle assembly.
- Under normal use conditions, the RX 400h AWD rear electric drive differential specifies only a fluid check at 45,000 km or 36 months, with no change interval listed for that condition.
- Under severe use conditions, the RX 400h AWD rear electric drive differential carries both a check interval of 45,000 km or 36 months and a fluid change interval of 90,000 km or 72 months, the latter being unique to the severe use designation.
- The 90,000 km or 72-month change interval assigned to the RX 400h AWD rear electric drive differential under severe use represents a considerably longer service span than the 30,000 km or 48-month change interval applied to the RX 300 and RX 350 AWD rear differentials.
- The RX 400h AWD rear electric drive differential specifications remain consistent at 1.8 liter capacity across all listed model year ranges from 2005-2009, with no variation in capacity or interval values between those ranges.
