Additional Notes

  • The INFINITI Q50 3.5 Hybrid AWD (HV37) transfer case holds 1 liter of fluid across all three generation spans covered, from 2013 through 2020.
  • A 1-liter transfer case capacity is a relatively modest figure, consistent with compact transfer units found in passenger car-based AWD systems rather than truck-derived four-wheel-drive assemblies.
  • The check interval is set at 15,000 km or 12 months, whichever comes first, and applies under normal use conditions for all three model year groupings: 2013-2015, 2015-2017, and 2018-2020.
  • The 15,000 km interval aligns the transfer case check schedule with a typical annual service cycle, meaning a vehicle driven at average mileage would reach the time-based threshold before the distance-based one in many real-world scenarios.
  • The specification is labeled as a check interval rather than a drain-and-fill interval, indicating the service action involves inspecting fluid level and condition rather than a mandatory full fluid replacement at each visit.
  • Capacity and check interval figures remain unchanged across the 2013-2015, 2015-2017, and 2018-2020 production spans, reflecting no revision to the transfer case service specification over the covered period.
