Additional Notes
- The Acura RDX 2.0 i-VTEC AWD rear differential holds a service fill capacity of 1.7 liters across both the USA and CAN specifications, meaning a routine drain-and-fill procedure uses that volume rather than the full system capacity.
- The USA specification lists a separate overhaul capacity of 1.95 liters, which represents the total fluid volume when the differential is fully disassembled and refilled from dry, a figure that differs from the 1.7-liter service fill used in standard maintenance.
- The CAN specification carries no distinction between overhaul and service fill capacities, listing only the 1.7-liter figure for all use conditions.
- Under severe use conditions, the USA specification calls for a rear differential fluid change interval of 15,000 miles, while the CAN specification sets the equivalent severe-use interval at 24,000 km.
- A first-change-only interval exists within the severe use category for both markets. The USA specification places the initial change at 7,500 miles, and the CAN specification places it at 12,000 km, each representing a shortened break-in interval before the standard severe-use schedule takes effect.
- The flexible interval condition, governed by the on-board maintenance system, is listed for both the USA and CAN specifications without a fixed mileage or kilometer value, indicating the vehicle's monitoring system determines the change point rather than a predetermined distance.
