Mercedes-Benz EQS-Class SUV, X296 (EU)

Brake fluid capacity & service interval

Mercedes-Benz EQS-Class SUV, X296 (EU) uses brake fluid with a capacity range between min and max. Service intervals require a change every 24 months. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • Across all five variants of the Mercedes-Benz EQS-Class SUV X296 covered here, the brake fluid fill level is specified as between the minimum and maximum marks on the reservoir, rather than as a fixed volume in liters or milliliters. A range-based fill specification of this kind is standard for brake fluid reservoirs, where the acceptable operating level is defined by two reference points rather than a precise measured quantity.
  • The EQS 450+, 296.623, the EQS 450 4MATIC, 296.624, the EQS 500 4MATIC, 296.634, and the EQS 580 4MATIC, 296.644 all share a starting year of 2022, while the EQS 680 4MATIC Maybach, 296.655 carries a starting year of 2023.
  • All five variants share an identical brake fluid change interval of 24 months under normal use conditions. A time-based interval of this kind reflects the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time and lowers the fluid's boiling point regardless of mileage accumulated.
  • The 24-month change interval applies uniformly across both single-motor rear-wheel-drive configurations and all-wheel-drive 4MATIC configurations, with no differentiation in service timing between the two drivetrain types.
  • Each variant's brake fluid specification is associated with the hydraulic brake system specifically. In electric vehicles, a conventional hydraulic brake circuit operates alongside or in coordination with regenerative braking, and the hydraulic side retains its own fluid maintenance requirements independent of the electric drivetrain.
  • The EQS 680 4MATIC Maybach, 296.655 shares the same 24-month brake fluid change interval and the same between-min-and-max fill specification as the lower variants, indicating no deviation in brake fluid service requirements for the Maybach sub-brand configuration.
