Slowly pour coolant into the reservoir tank until it reaches the FULL line.

Standard Capacity

Item	Specified Condition
for LHD	3.1 liters (3.3 US qts, 2.7 Imp. qts.)
for RHD	2.9 liters (3.0 US qts, 2.6 Imp. qts.)

Note

To prevent foreign matter such as dust or dirt from entering the cooling system, make sure to confirm that the container used to add coolant is clean and free of foreign matter such as dust or dirt.

When using the GTS:

Connect the GTS to the DLC3.
Turn the power switch on (IG).
Enter the following menus: Powertrain / Hybrid Control / Active Test / Activate the Water Pump.

Keep the coolant at the FULL line in the reservoir 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 reservoir tank improves.

Tech Tips

If free spinning of the inverter water pump is detected for approximately 5 seconds, failsafe control will be activated to suspend the operation of the pump for approximately 15 seconds and resume operation for approximately 4 seconds repeatedly. Operation of the inverter water pump will return to normal if coolant is added.
Loud noise made by the inverter water pump and poor circulation of coolant in the reservoir tank indicates that there is air in the cooling system.

When not using the GTS:

Turn the power switch on (READY).[*1]
Turn the power switch off and add coolant to the FULL line because the coolant level drops as the air bleeds.[*2]
Note
- Be sure to turn the power switch off before adding SLLC.
- 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.

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 reservoir tank improves.

Tech Tips

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

After the air is completely bled from the cooling system, tighten the reservoir tank cap.
Add coolant to the FULL line of the reservoir tank.

INSPECT FOR COOLANT LEAK (for Inverter)
