Additional Notes
- The Mazda 5 CW automatic transaxle carries a dry fill capacity of 5 liters, which represents the amount of fluid required when filling a completely drained or newly rebuilt unit with no residual fluid present.
- A service fill of 3 liters applies to the 1.8, 2.0, and 2.0 DISI i-stop variants across 2010-2015, reflecting the smaller volume exchanged during a routine fluid change where fluid retained in the torque converter and passages is not fully expelled.
- The total system capacity of 8.14 liters across all three engine variants indicates the full fluid volume held within the transaxle assembly, including the torque converter, valve body, and internal circuits.
- The gap between the 5-liter dry fill and the 8.14-liter total capacity confirms that approximately 3.14 liters remain in the torque converter and hydraulic circuits even after a conventional drain procedure.
- All three configurations, the 1.8, the 2.0, and the 2.0 DISI i-stop, share identical capacity figures for dry fill, service fill, and total volume, indicating a common automatic transaxle unit across the 2010-2015 model range.
- A 12-month check interval is specified under normal use conditions for all three variants, meaning the fluid level and condition are to be inspected on an annual basis regardless of mileage accumulation.
