Additional Notes

  • The INFINITI Q50 HV37 (EU) brake fluid specifications cover the hydraulic brake system across all listed configurations, with the fluid level maintained between the minimum and maximum reservoir marks rather than a fixed volume fill.
  • Under normal use conditions, the Q50 3.5 Hybrid and Q50 3.5 Hybrid AWD both follow a two-stage service schedule: a fluid level check at 15,000 km or 12 months, followed by a full fluid change at 30,000 km or 24 months.
  • Under severe use conditions, the check interval is eliminated entirely, and a full brake fluid change is required at 15,000 km or 12 months — exactly half the change interval specified for normal use.
  • The halved change interval under severe conditions reflects the accelerated degradation brake fluid can experience when subjected to repeated high-temperature cycling, which lowers the fluid's boiling point and increases the risk of vapor lock.
  • The 2013-2015 and 2015-2017 model year ranges for the Q50 3.5 Hybrid AWD share an overlapping year (2015), yet both carry identical normal and severe use specifications, indicating no change in brake fluid service requirements at that production boundary.
  • The 2018-2020 production range applies to both the AWD and non-AWD Q50 3.5 Hybrid variants, and both share the same normal and severe use intervals, meaning drivetrain configuration has no effect on brake fluid service scheduling within those years.
  • Across all model year groupings from 2013 through 2020, the normal-use change interval remains fixed at 30,000 km or 24 months, indicating no revision to the standard brake fluid replacement schedule over the entire covered period.
