Additional Notes

  • Every variant in the Mercedes-Benz EQS-Class SUV X296 lineup carries two separate cooling circuits: a primary cooling system and a secondary cooling system, each with its own distinct capacity figure.
  • The primary cooling system holds 12 liters across all variants, including the EQS 450+, EQS 450 4MATIC, EQS 500 4MATIC, EQS 580 4MATIC, and EQS 680 4MATIC Maybach.
  • The secondary cooling system holds 15 liters across all variants, a figure 3 liters greater than the primary circuit, reflecting the additional thermal management demands of electric drivetrains where battery and power electronics cooling often require a dedicated loop.
  • The combined coolant volume across both circuits totals 27 liters per vehicle, which is a notably high figure compared to conventional internal combustion engine vehicles and is consistent with the multi-circuit architecture common in battery electric platforms.
  • All coolant change intervals are rated under normal use conditions, with a service interval of 210,000 km or 144 months, whichever comes first. 144 months equals 12 years, placing this among the longest coolant service intervals found in passenger vehicles.
  • The EQS 680 4MATIC Maybach (296.655) shares the identical 12-liter primary and 15-liter secondary capacities as the other variants, and carries the same 210,000 km / 144-month change interval under normal use conditions.
  • The interval and capacity specifications are consistent across all four 4MATIC variants and the single-motor EQS 450+, indicating no differentiation in cooling service requirements between single-motor and dual-motor configurations within the X296 platform.
