Kia Sportage, NQ5 (USA / CAN)

Additional Notes

• The Kia Sportage NQ5 rear differential fluid capacity is specified as a range of 0.53–0.63 liter across all listed configurations. A range rather than a fixed value is typical for rear differentials, where the fill procedure involves adding fluid until it reaches the level plug opening, making the exact accepted volume dependent on the unit's orientation and fill angle.
• The 1.6 T-GDI Hybrid AWD, 1.6 T-GDI Plug-in Hybrid AWD, 2.5 GDI, and 2.5 GDI AWD variants all share the identical 0.53–0.63 liter capacity specification for the rear differential. No variation in fluid volume exists across engine types or drivetrain configurations in the listed data.
• Under normal use conditions, the service requirement for the rear differential is limited to a fluid level check at 40,000 miles or 48 months, whichever comes first. No fluid change interval is assigned to normal use across any of the listed configurations.
• Under severe use conditions, the rear differential retains the same check interval of 40,000 miles or 48 months, with the addition of a fluid change at 72,000 miles. The check interval preceding the change point allows for condition monitoring before the mandatory replacement mileage is reached.
• The 72,000-mile fluid change interval under severe use applies uniformly to all four configurations: the 1.6 T-GDI Hybrid AWD, the 1.6 T-GDI Plug-in Hybrid AWD, the 2.5 GDI, and the 2.5 GDI AWD. No configuration carries a more or less frequent change requirement under severe conditions.
• The 48-month time limit on the check interval means the service trigger can be reached by calendar time before the 40,000-mile mark, depending on annual mileage. Both conditions apply concurrently, and whichever is reached first would govern the service timing.
