Additional Notes

  • The INFINITI EX J50 (EU) transfer case holds 1 liter of fluid across all listed configurations, a figure consistent with the compact transfer boxes found in crossover-sized all-wheel-drive platforms.
  • The EX30D J50 covering 2010-2011 carries a normal-use check interval of 15,000 km or 12 months, whichever comes first.
  • The EX30D J50 covering 2011-2013 sees a revised normal-use check interval of 20,000 km or 12 months, a longer distance threshold compared to the earlier 2010-2011 specification for the same engine variant.
  • The EX37 J50 spanning 2008-2010 and the EX37 J50 spanning 2010-2013 share an identical normal-use check interval of 15,000 km or 12 months, meaning no interval revision was applied to the petrol variant across those model years.
  • The 12-month time component appears in every listed row regardless of engine type or model year, indicating that calendar-based servicing runs parallel to the distance threshold under normal use conditions for all configurations.
  • The capacity figure of 1 liter applies uniformly to both the diesel EX30D and the petrol EX37 variants, reflecting a shared transfer box unit rather than engine-specific hardware differences in fluid volume.
