Additional Notes

  • The INFINITI QX50 3.7 AWD (J50) transfer case holds 1 liter of fluid, a figure consistent with the compact transfer units found in rear-biased AWD systems of similar displacement and class.
  • The 1-liter capacity applies equally across both normal and severe use conditions, meaning the physical fill volume of the transfer case does not differ based on operating environment.
  • Under normal use conditions, the service specification calls for a fluid check at 10,000 miles or 12 months, with no fluid change interval listed for that condition.
  • Under severe use conditions, the same 10,000-mile or 12-month check interval applies, with an additional fluid change interval set at 20,000 miles or 24 months.
  • The distinction between the normal and severe use rows is meaningful in practice: severe conditions introduce a mandatory drain-and-fill cycle that normal conditions do not carry, despite sharing the same inspection frequency.
