Smart fortwo, 450

Brake fluid capacity & service interval

Smart fortwo 450 uses brake fluid with a capacity of 0,5 liter. Service intervals include checking at 10000 km or 12 months and 15000 km or 12 months, with changes at 20000 km or 24 months and 30000 km or 24 months. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Smart fortwo 450 hydraulic brake system holds 0,5 liter of brake fluid across all four configurations covered in the 2004-2006 model years, meaning the fill volume is consistent regardless of engine output or variant.
  • The 37 kW and 45 kW petrol variants share identical service intervals, with a brake fluid check scheduled at 15000 km or 12 months and a full fluid change at 30000 km or 24 months under normal use conditions.
  • The fortwo Brabus carries the same 0,5 liter capacity as the standard petrol variants, but under normal use conditions the check interval is shortened to 10000 km or 12 months and the change interval to 20000 km or 24 months, both tighter than the 37 kW and 45 kW schedules.
  • The distance-based check interval for the Brabus is 33% shorter than the one applied to the 37 kW and 45 kW variants, while the time-based component of 12 months remains the same across all three petrol configurations.
  • The fortwo cdi shares the 10000 km or 12 months check interval with the Brabus under normal use conditions, placing both on a more frequent inspection schedule than the standard petrol variants.
  • The fortwo cdi specification lists only a check interval and does not include a change interval entry, making the cdi the only configuration in the 2004-2006 range without a documented fluid change schedule in the provided data.
