Additional Notes

  • The Mercedes-Benz EQE-Class SUV (X294) carries two separate cooling circuits across all listed variants: a primary cooling system and a secondary cooling system, each with its own distinct fluid capacity.
  • The secondary cooling system holds 13 liters across every listed variant without exception, making it the larger of the two circuits regardless of the drivetrain configuration.
  • Primary cooling system capacity varies by variant. The EQE 300 (294.611), EQE 350+ (294.621), EQE 43 AMG 4MATIC (294.632), and EQE 53 AMG 4MATIC (294.653) all specify 11 liters, while the EQE 350 4MATIC (294.612) and EQE 500 4MATIC (294.622) specify 12 liters.
  • The 1-liter difference in primary circuit capacity between the single-motor rear-wheel-drive variants and the dual-motor 4MATIC variants such as the EQE 350 4MATIC and EQE 500 4MATIC reflects the additional thermal management demands of a second electric motor at the front axle.
  • The AMG variants — the EQE 43 AMG 4MATIC and EQE 53 AMG 4MATIC — share the 11-liter primary circuit capacity with the single-motor EQE 300 and EQE 350+, despite being all-wheel-drive configurations.
  • All listed variants share a uniform coolant change interval of 210,000 km or 144 months (12 years), whichever comes first, under normal use conditions. The 144-month time limit means the interval is bounded by both distance and calendar time.
  • A 210,000 km service interval is notably long by conventional standards, reflecting the reduced thermal cycling stress on coolant in electric drivetrains compared to internal combustion engines, where combustion heat causes faster coolant degradation.
  • All specifications are designated for normal use conditions only. No severe-use interval variations are listed for any variant in the X294 lineup.
