Additional Notes

  • Across all four variants of the Mercedes-Benz EQS-Class Sedan V297, each configuration 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 every listed variant, including the EQS 450+, EQS 450 4MATIC, EQS 580 4MATIC, and EQS AMG 4MATIC+, indicating a consistent primary circuit volume regardless of drivetrain or performance tier.
  • The secondary cooling system holds 15 liters across all four variants, making the secondary circuit the larger of the two by 3 liters in every case.
  • The combined coolant volume across both circuits totals 27 liters per vehicle, a figure that reflects the thermal management demands of high-voltage electric drivetrains, which require cooling for battery packs, power electronics, and electric motors in addition to any cabin climate hardware.
  • All eight rows carry a normal use condition, meaning the stated intervals apply to standard operating environments rather than elevated-stress or severe-duty cycles.
  • The coolant change interval is 130,500 miles or 144 months for both circuits across all variants. 144 months equals 12 years, placing this among the longest factory-specified coolant service intervals found in passenger vehicles.
  • The EQS 450+ (297.123) and EQS 580 4MATIC (297.144) share identical capacity and interval figures for both cooling circuits, despite representing different power outputs and drivetrain configurations within the V297 lineup.
  • The EQS AMG 4MATIC+ (297.155) carries the same 12-liter primary and 15-liter secondary capacities as the non-AMG variants, along with the same 130,500-mile and 144-month change interval under normal use conditions.
