Additional Notes

  • The Kia Rio DC automatic transaxle carries a fluid capacity of 5.9 liters across both the 1.5 16V (2000-2002) and 1.6 (2003-2005) Canadian configurations, indicating a service fill volume rather than a full overhaul or dry fill amount.
  • For the 1.5 16V (CAN) under normal use conditions, the fluid check interval is set at 7,500 miles or 6 months, with a change interval of 30,000 miles or 24 months.
  • Under severe use conditions, the 1.5 16V (CAN) retains the same 30,000-mile change distance as the normal schedule, though the time-based change interval shortens to 18 months rather than 24 months.
  • The check interval for the 1.5 16V (CAN) under severe use conditions tightens to 5,000 miles or 3 months, compared to 7,500 miles or 6 months under normal use, reflecting the added stress placed on the fluid in demanding operating conditions.
  • The 1.6 (CAN) covering model years 2003-2005 shares the same 5.9-liter capacity and the same normal-use check and change intervals as the earlier 1.5 16V, despite the engine displacement change between the two generations.
