Additional Notes
- The Mercedes-Benz eActros 983 (EU) uses a flexible service interval governed by an on-board maintenance system across all variants and all three cooling circuits, meaning coolant service timing is determined by the vehicle's own monitoring rather than a fixed mileage or time schedule.
- The high voltage battery cooling system on the eActros 300 and eActros 400 carries a capacity range of 45-60 liters. A range rather than a fixed value typically reflects variation between specific configurations or build states within the same variant.
- The heater cooling system on the eActros 300 and eActros 400 holds a fixed capacity of 25 liters, making it the most precisely defined of the three cooling circuits on those variants.
- The brake cooling system on the eActros 300 and eActros 400 has the widest capacity range among the three circuits at 39-58 liters, a spread of 19 liters that suggests meaningful variation depending on axle configuration or brake system specification.
- The eActros 600, introduced from 2023, shares identical coolant capacities across all three circuits with the eActros 300 and eActros 400: 45-60 liters for the high voltage battery circuit, 25 liters for the heater circuit, and 39-58 liters for the brake circuit.
- Across all three variants, the heater cooling circuit at 25 liters is consistently the smallest of the three systems, while the high voltage battery and brake circuits both carry substantially larger and variable volumes, reflecting the thermal demands of electric drivetrain and retardation systems in heavy-duty operation.
