Additional Notes

  • The Kia Optima TF (EU) manual transaxle fluid capacity is specified as a range rather than a single fixed value across all engine variants, reflecting the tolerance band used during a service fill to account for fluid remaining in the unit after draining.
  • The 1.7 CRDi and 2.4 MPI variants share an identical transaxle fluid capacity range of 1.8–1.9 liters, while the 2.0 CVVL carries a slightly higher range of 1.9–2.0 liters, indicating a marginally larger transaxle housing in the petrol four-cylinder application.
  • Under normal use conditions, the 1.7 CRDi transaxle fluid interval is a check at 48 months or 60,000 km, whichever comes first, with no fluid change specified at that interval.
  • Under severe use conditions across all listed variants, a fluid change is required at 120,000 km, a requirement absent from the normal use schedule, where only a fluid level check is called for.
  • The check interval under severe conditions is expressed as 60,000 km or 48 months, placing the distance threshold ahead of the time threshold in the specification order, whereas the normal use schedule lists the time threshold of 48 months first.
  • The 1.7 CRDi and 1.7 CRDi DPF variants carry identical capacity and interval specifications across both their 2011–2014 and 2014–2016 sub-ranges, meaning the addition of a diesel particulate filter in the DPF variant did not alter the manual transaxle service requirements.
  • The 2.0 CVVL is the only petrol engine in the listed configurations to span the full 2011–2016 model year range without a mid-range sub-division, while the 2.4 MPI enters the specification from 2012 onward.
