Additional Notes

  • The Toyota Prius C, NHP10 carries two separate cooling circuits: one for the combustion engine with a 5.3-liter capacity, and a dedicated electric drive cooling system with a 1.6-liter capacity.
  • The 5.3-liter figure for the main cooling system represents a full system fill, accounting for the radiator, hoses, reservoir, and engine passages typical of a hybrid powertrain layout.
  • The electric drive cooling circuit's 1.6-liter capacity reflects a smaller, self-contained loop designed specifically to regulate the power electronics and motor-generator units rather than a combustion engine.
  • Under normal use conditions in the Canadian market, both the main and electric drive cooling systems share a change interval of 80,000 km or 60 months, whichever comes first.
  • The first-change-only designation in the Canadian specification extends the main cooling system's change interval to 160,000 km or 120 months, meaning the initial factory-fill coolant is rated for a longer service life before the standard 80,000 km cycle applies to subsequent fills.
  • In the USA market under normal use, both cooling circuits are scheduled for a change at 50,000 miles or 60 months, with checks required every 15,000 miles or 18 months.
  • The first-change-only interval for the USA electric drive cooling system extends to 150,000 miles or 180 months, which is notably longer than the USA main cooling system's first-change interval of 100,000 miles or 120 months.
  • Canadian-market specifications call for coolant checks every 8,000 km or 6 months, a more frequent inspection schedule compared to the USA market's 15,000-mile or 18-month check interval, despite both markets sharing the same 5.3-liter and 1.6-liter capacities.
