Additional Notes

  • The Kia Rio UB 1.6 manual transaxle carries a fluid capacity of 1.8-1.9 liters for the 2011-2015 model years, while the 2015-2017 variant uses a slightly smaller 1.6-1.7 liter fill. The capacity range in both cases reflects acceptable variation between a drain-and-refill service fill and a fully topped-off state.
  • For the 2011-2015 Rio 1.6 manual transaxle under normal use conditions, the specification calls for a fluid check at 37,500 miles or 48 months, with no fluid change interval listed for normal use.
  • Under severe use conditions for the 2011-2015 Rio 1.6 manual transaxle, a fluid change is specified at 80,000 miles, in addition to the same 37,500-mile or 48-month check interval shared with the normal use schedule.
  • The 2015-2017 Rio 1.6 manual transaxle under normal use conditions carries a check interval of 37,500 miles or 30 months, which is a shorter time-based interval than the 48-month period specified for the 2011-2015 configuration at the same mileage threshold.
  • Under severe use conditions, the 2015-2017 Rio 1.6 manual transaxle specifies a fluid change at 75,000 miles, which is 5,000 miles shorter than the 80,000-mile change interval listed for the 2011-2015 severe use schedule.
  • Both the 2011-2015 and 2015-2017 Rio 1.6 manual transaxle specifications present capacity as a range rather than a fixed value, which is standard practice for manual transmission fluid fills where the exact quantity retained can vary slightly depending on the drain angle and refill method.
