Additional Notes

  • Across all Smart fortwo 453 variants covered here, brake fluid capacity is expressed as "between min and max" rather than a fixed volume, which reflects how brake fluid reservoirs are serviced by topping up to the marked level rather than by draining and refilling a measured quantity.
  • The 45 kW variant, chassis code 453.341, carries a standard change interval of 24 months under normal use conditions for the hydraulic brake system.
  • A 36-month change interval applies to the 453.341 exclusively under the first change only condition, meaning the extended interval is recognized solely for the initial service and not for subsequent ones.
  • The same dual-interval structure, 24 months for normal use and 36 months for the first change only, is shared by the 52 kW variant across chassis codes 453.342, 453.343, 453.442, and 453.443.
  • The 66 kW variant, covering chassis codes 453.344, 453.444, and 453.453, follows the identical interval pattern, with 24 months under normal use and 36 months for the first change only.
  • The Smart fortwo Brabus at 80 kW, chassis codes 453.462 and 453.362, shares the same 24-month normal and 36-month first-change-only intervals as the lower-output variants, despite the higher power output.
  • The Brabus 453.462/362 variant has a start year of 2016, which is two years later than the 2014 start year of the 45 kW, 52 kW, and 66 kW configurations within the same 453 generation.
  • The first change only designation, present across all four power variants, indicates the brake fluid interval is longer at initial service, a practice sometimes associated with factory-fill fluid having different properties or the system being new and uncontaminated at the point of first service.
