Additional Notes

  • The INFINITI QX55 2.0 AWD transfer case holds 0.31 liter of fluid, a notably small capacity consistent with compact transfer cases found in crossover-based AWD systems rather than traditional body-on-frame designs.
  • A check interval of 7,500 miles or 12 months applies under normal use conditions, meaning the fluid level and condition are to be inspected on an annual basis or at each oil service cycle, whichever comes first.
  • The change interval for the transfer case fluid is set at 20,000 miles or 24 months under normal use, placing a full fluid replacement on a two-year cycle when mileage accumulation is moderate.
  • Both the 2021-2022 and the 2022 configurations share identical capacity and interval specifications at 0.31 liter, with check intervals at 7,500 miles or 12 months and change intervals at 20,000 miles or 24 months, indicating no variation in transfer case service requirements across those entries.
