Additional Notes

  • The Irisbus CityClass carries 6.5 liters of power steering fluid, a volume consistent with the large hydraulic systems found in full-size urban transit buses, where longer steering linkages and heavier axle loads require greater fluid reserves than passenger cars.
  • Both the 491.10.22 and 491.12.22 variants share an identical 6.5-liter power steering fluid capacity, indicating no difference in the hydraulic system volume between the two configurations across the 1995-2006 model span.
  • The capacity figure of 6.5 liters applies under normal use conditions, meaning standard urban service operation rather than severe-duty or off-cycle scenarios.
