Lexus RX, XU10 (EU)

Additional Notes

• The Lexus RX 300 (XU10, EU) automatic transaxle holds 8.9 liters at dry fill, a figure that reflects the total fluid volume required when the transmission is completely empty, such as after a full overhaul or component replacement.
• The service fill capacity across all RX 300 configurations is 3.9 liters, representing the partial volume exchanged during a routine fluid change, which accounts for fluid retained in the torque converter and valve body that cannot be drained by gravity alone.
• The gap between the 8.9-liter dry fill and the 3.9-liter service fill means a standard drain-and-fill procedure replaces less than half the total fluid volume in the transaxle.
• Under normal use conditions, the RX 300 and RX 300 AWD both specify a fluid check interval of 45,000 km or 36 months, with no fluid change interval listed for normal use.
• Under severe use conditions, the same 45,000 km / 36-month check interval applies, and a fluid change interval of 90,000 km or 72 months is additionally specified.
• The severe-use change interval of 90,000 km or 72 months is exactly double the check interval, meaning a fluid change under severe conditions would coincide with every second scheduled check.
• The front-wheel-drive RX 300 and the all-wheel-drive RX 300 AWD share identical automatic transaxle fluid capacities and service intervals across all listed model years, indicating no differentiation in transmission fluid servicing between the two drivetrain configurations.
• Specifications for the 2000-2001 and 2001-2003 production periods are identical in both capacity values and service intervals, with the 2001 model year appearing in both ranges as an overlap point.
