Additional Notes

  • Across all Smart forfour 453 configurations covered here, the brake fluid fill level is specified as between the minimum and maximum marks on the reservoir, rather than as a fixed volume. A "between min and max" specification is typical for brake fluid reservoirs, where the exact quantity depends on brake pad wear and system condition at the time of service.
  • The Smart forfour 453 (45 kW), chassis code 453.041, carries a 24-month brake fluid change interval under normal use conditions for the hydraulic brake system.
  • A separate first-change-only interval of 36 months applies to the 453.041 (45 kW) variant. A first-change-only designation means the extended interval is valid solely for the initial fluid replacement from new, after which subsequent changes revert to the standard 24-month cycle.
  • The 52 kW variants, chassis codes 453.042 and 453.043, share identical brake fluid service intervals with the 45 kW model: 24 months under normal use and 36 months for the first change only.
  • The 66 kW variants, chassis codes 453.044 and 453.053, follow the same interval structure as the lower-output models, with a 24-month normal interval and a 36-month first-change-only interval for the hydraulic brake system.
  • The forfour Brabus (80 kW), chassis code 453.062, covering 2016-2019, also specifies a 24-month normal change interval and a 36-month first-change-only interval. Despite the higher output rating of the Brabus variant, the brake fluid service schedule does not differ from the other forfour 453 configurations in the specifications.
