Kia Sorento, MQ4 (EU)

Additional Notes

• The transfer case fluid capacity across all 1.6 T-GDI Hybrid and Plug-in Hybrid AWD variants is a uniform 0.65 liter. A fixed single-value capacity like this typically reflects a sealed or compact transfer unit with a precisely defined sump volume, leaving little tolerance for variation during a service fill.
• The 2.2 CRDI AWD variants carry a capacity range of 0.48–0.53 liter rather than a fixed value. A range specification of this kind usually accounts for minor variation in fluid level acceptance depending on the unit's orientation, temperature at fill time, or manufacturing tolerances across production runs.
• The Kia Sorento MQ4 (EU) 2.2 CRDI diesel AWD variants are specified with a lower transfer case fluid volume than the hybrid and plug-in hybrid AWD variants. The diesel units hold 0.48–0.53 liter compared to the 0.65 liter specified for the electrified drivetrains, reflecting a difference in transfer unit design between the two powertrain families.
• Under normal use conditions, all variants across the specification set share the same transfer case check interval: 48 months or 60,000 km, whichever comes first. No fluid change interval is listed for normal use, meaning the service action defined for that condition is inspection only.
• Under severe use conditions, the 1.6 T-GDI Hybrid and Plug-in Hybrid AWD variants specify both a check interval of 60,000 km or 48 months and a fluid change at 120,000 km. Severe use classifications generally apply to operating environments involving frequent towing, off-road driving, extreme temperatures, or repeated short-distance trips.
• Under severe use conditions, the 2.2 CRDI AWD variants list only a fluid change at 120,000 km, with no separate check interval stated. This contrasts with the hybrid variants, which carry an explicit check interval alongside the change interval under the same severe use condition.
• The 1.6 T-GDI Hybrid AWD covers model years 2020-2024, while the higher-output 1.6 T-GDI Hybrid (158 kW) AWD variant begins from 2024. Both share identical transfer case fluid capacity and service intervals across both normal and severe use conditions.
• The 1.6 T-GDI Plug-in Hybrid AWD covers 2021-2024, and the 1.6 T-GDI Plug-in Hybrid (185 kW) AWD starts from 2024. As with the standard hybrid variants, the transfer case specifications are identical between the two generations of the plug-in hybrid, with 0.65 liter capacity and the same check and change intervals under both use conditions.
• The 2.2 CRDI diesel AWD is represented by two distinct output ratings across the specification set: 148 kW for 2020-2022 and 142 kW from 2022 onward. Despite the difference in power output, the transfer case fluid capacity and service intervals are identical between the two diesel variants.
