Additional Notes

  • The Irisbus EuroPolis 8/9/10m Euro 4 automatic transmission is listed with two distinct fluid capacities: 20 liters and 30 liters. A 10-liter difference of this magnitude typically reflects different transmission unit variants installed across the body length range, as larger vehicles commonly accommodate larger transmission assemblies.
  • Under normal use conditions, both the 20-liter and 30-liter capacity configurations share an identical service interval of 120,000 km or 36 months, whichever comes first. The dual-trigger format means the time limit applies even when mileage accumulation is low.
  • The alternative (acceptable) use condition reduces the change interval significantly to 45,000 km or 24 months for both capacity variants. Compared to the normal use interval of 120,000 km, the alternative condition shortens the distance-based interval by 75,000 km.
  • The time-based component of the alternative (acceptable) interval is 24 months, compared to 36 months under normal use. For a vehicle accumulating low annual mileage, the 24-month ceiling would become the governing factor rather than the 45,000 km distance limit.
  • Both capacity figures, 20 liters and 30 liters, apply across the same 2006-2008 model years and the same Euro 4 emission standard designation, indicating the capacity difference is tied to transmission variant rather than a year-over-year specification change.
