Additional Notes

  • Across all three configurations in the Toyota Prius XW60 lineup — the standard Hybrid, Hybrid AWD, and Prime Plug-in Hybrid — the main cooling system capacity is 6.1 liters, while the power control unit carries a separate 1.6-liter capacity.
  • The 1.6-liter power control unit circuit is a dedicated cooling loop for the hybrid electronics, kept separate from the 6.1-liter engine cooling circuit rather than shared with it.
  • A coolant check interval of every 15,000 miles or 18 months applies to all three configurations under normal use conditions.
  • Under normal use, the coolant change interval is 50,000 miles or 60 months for the Prius Hybrid, Prius Hybrid AWD, and Prius Prime Plug-in Hybrid alike.
  • A first-change-only condition extends the initial coolant change interval to 100,000 miles or 120 months — double the normal change interval — for all three configurations.
  • The 120-month first-change-only interval reflects the use of long-life coolant from the factory, which is formulated to remain serviceable well beyond a standard fill's service life before requiring replacement.
  • After the first-change-only service is completed, subsequent changes revert to the normal interval of 50,000 miles or 60 months across all configurations.
  • The Prius Hybrid AWD shares identical cooling system capacities and service intervals with the front-wheel-drive Prius Hybrid, indicating the addition of the rear electric motor does not alter the cooling system specifications.
