Additional Notes

  • The INFINITI QX50 2.0 AWD transfer case holds 0.31 liter of fluid, a notably small volume consistent with a compact transfer box unit rather than a larger, gear-heavy assembly.
  • A capacity as low as 0.31 liter means even minor fluid loss represents a significant percentage of the total fill, making the 10,000 km or 6-month check interval a meaningful safeguard against running the unit low.
  • The specified interval is a check interval rather than a drain-and-fill interval, meaning the service action is verification of fluid level rather than a scheduled replacement at that mileage or time mark.
  • The 6-month time component of the check interval runs independently of distance, so a vehicle covering low annual mileage would still reach a service check point on calendar time before accumulating 10,000 km.
  • The listed use condition for the 2018-2020 QX50 2.0 AWD transfer case is normal, meaning the 10,000 km or 6-month check interval applies to standard operating conditions rather than a more demanding severe-use schedule.
