- REMOVE OIL PAN PROTECTOR
- DRAIN COOLANT (for Inverter) WARNING:
- To avoid the danger of being burned, do not remove the reserve tank cap or drain cock plug while the coolant (for inverter) is still hot.
- Pressurized, hot coolant (for inverter) and steam may be released and cause serious burns.
NOTE:- Do not reuse the drained coolant because it may contain foreign objects.
- Collect the drained coolant and measure its volume to establish a benchmark. When adding coolant, make sure to add more coolant than the measured amount.
- ADD COOLANT (for Inverter) NOTE:
- Do not reuse the drained coolant because it may contain foreign objects.
- If the vehicle is driven with air in the inverter cooling system, damage may occur and the following DTCs may be set.

Standard Capacity
2.5 liters (2.6 US qts, 2.2 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.
- When using the Techstream:
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Enter the following menus: Powertrain / Hybrid Control / Active Test / Activate the Inverter Water Pump.
Powertrain > Hybrid Control > Active Test
Tester Display Activate the Inverter Water Pump - While adding coolant to the inverter reserve tank assembly to keep the coolant at the FULL line and compensate for the drop in the coolant level as the air bleeds, operate and stop the inverter water pump assembly at 1 minute intervals.
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 inverter reserve tank assembly improves.
HINT:
Loud noises made by the inverter water pump assembly and poor circulation of coolant in the inverter reserve tank assembly indicate that there is air in the cooling system.
- When not using the Techstream:
- Turn the power switch on (READY). [*1]
- Turn the power switch off and add coolant to the FULL line as the coolant level will drop 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 power switch is on (READY) as the engine will operate intermittently.
- 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 inverter reserve tank assembly improves.
HINT:
Loud noises made by the inverter water pump assembly and poor circulation of coolant in the inverter reserve tank assembly indicate that there is air in the cooling system.
- After the air is completely bled from the cooling system, add coolant to the FULL line of inverter reserve tank assembly and install the reserve tank cap.
