  • The capacity specification for the hydraulic brake system on both configurations is expressed as a fill range between the minimum and maximum reservoir marks, rather than a fixed volume figure, which is characteristic of a service top-up or level-maintenance fill rather than a full system overhaul quantity.
  • The 12-month change interval applies uniformly across the 2019-2024 model years for both the G 550 and G 63 AMG variants, with no variation tied to engine type or trim level within the W463B generation.
