  1. Slowly pour coolant into the reserve tank until it reaches the full line.

    Coolant quantity:
    2.1 liters (2.2 US qts, 1.8 Imp. qts.)

  1. When using the intelligent tester:

    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Active Test / Activate the Water Pump.

    4. Keep the coolant at the full line in the reserve tank to compensate for the drop in coolant level when the air bleeds.

      Standard:
      Air bleeding from the inverter cooling system is completed when the noise made by the inverter water pump assembly becomes smaller and the circulation of coolant in the reserve tank improves.

      HINT:
      Loud noise made by the inverter water pump assembly and poor circulation of coolant in the reserve tank indicates that there is air in the cooling system.

  1. When not using the intelligent tester:

    1. Turn the power switch on (READY). [*1]

    2. Turn the power switch off and add coolant to the full line because the coolant level drops as the air bleeds. [*2]

      NOTICE:
      1. Be sure to turn the power switch off before adding SLLC.
      2. Do not work on the components in the engine compartment while the vehicle is in the READY-on state because the engine is in intermittent operation.

    3. Repeat steps [*1] and [*2] until air bleeding from the cooling system is completed.

      Standard:
      Air bleeding from the inverter cooling system is completed when the noise made by the inverter water pump assembly becomes smaller and the circulation of coolant in the reserve tank improves.

      HINT:
      Loud noise made by the inverter water pump assembly and poor circulation of coolant in the reserve tank indicates that there is air in the cooling system.

  1. After the air is completely bled from the cooling system, tighten the reserve tank cap.



    A248471

  1. Add coolant to the full line of the reserve tank.



24. INSPECT FOR COOLANT LEAK (for Inverter)
