Kia Sorento, XM (EU)

Additional Notes

• The rear differential fluid capacity across the Kia Sorento XM (EU) 4WD lineup is either 0.6 liter or 0.7 liter, depending on the engine. The 0.6-liter figure applies to all four-cylinder configurations, covering the 2.0 CRDi, 2.0 CRDi DPF, 2.2 CRDi DPF, 2.4, and 2.4 GDI variants. These small fill volumes are characteristic of a compact rear differential housing rather than a full axle assembly overhaul quantity.
• The Sorento 3.5 V6 4WD (2009-2015) carries a rear differential fluid capacity of 0.7 liter, which is 0.1 liter higher than all four-cylinder variants. A larger displacement V6 engine typically produces more torque, and the slightly larger differential housing that accommodates greater load capacity accounts for the marginally higher fluid volume.
• Under normal use conditions, all configurations across the lineup share an identical check interval of 48 months or 60,000 km for the rear differential fluid. No fluid change interval is specified under normal use, meaning the service action defined for that condition is inspection only.
• Under severe use conditions, the check interval is expressed as 60,000 km or 48 months across all configurations. While the numerical values match the normal-use interval, the severe-use rows additionally carry a fluid change interval of 210,000 km or 120 months, a requirement absent from the normal-use entries.
• The severe-use change interval of 210,000 km or 120 months applies uniformly to every engine variant in the Sorento XM (EU) 4WD range. At 120 months, the time-based threshold equals 10 years, making the distance threshold of 210,000 km the more likely limiting factor for higher-mileage vehicles.
• The 2.0 CRDi 4WD and 2.0 CRDi 4WD DPF variants share identical rear differential fluid specifications in both capacity and service intervals across normal and severe use conditions. The only distinction between the two configurations is the presence of a diesel particulate filter on the DPF variant, which does not affect differential servicing requirements.
• The 2.2 CRDi 4WD DPF has a model year range starting from 2009, while the 2.0 CRDi variants begin from 2012. Despite the different introduction years, both engine families converge on the same 0.6-liter rear differential capacity and the same check and change intervals.
• The 2.4 GDI 4WD variant, available from 2012-2015, uses gasoline direct injection, distinguishing it from the standard 2.4 4WD available from 2009-2015. Both share a 0.6-liter rear differential capacity and identical service intervals, indicating the induction system difference has no bearing on differential fluid specifications.
