Additional Notes

  • The Kia K5 DL3 rear differential fluid capacity is specified as a range of 0.53–0.63 liter across all listed AWD configurations, which is consistent with a compact rear drive module rather than a traditional open differential housing.
  • The range format of 0.53–0.63 liter reflects a service fill tolerance, meaning the acceptable quantity sits between a minimum and maximum mark rather than a single fixed volume.
  • Under normal use conditions, the 1.6 T-GDI AWD (2020-2024) rear differential calls for a fluid check at 40,000 miles or 48 months, with no fluid change interval listed for that use condition.
  • Under severe use conditions, the 1.6 T-GDI AWD (2020-2024) retains the same 40,000-mile or 48-month check interval but adds a fluid change at 72,000 miles.
  • The 2.5 GDI AWD configuration, introduced from 2025, carries a slightly shorter check interval of 37,500 miles or 48 months under normal use conditions, compared to the 40,000-mile threshold on the 1.6 T-GDI AWD.
  • Under severe use conditions, the 2.5 GDI AWD specifies a fluid change at 75,000 miles, which is 3,000 miles longer than the 72,000-mile change interval assigned to the 1.6 T-GDI AWD under the same use condition.
  • The 48-month time limit appears consistently across all four rows regardless of engine or use condition, indicating a time-based ceiling that applies in parallel with the mileage threshold.
