CHARGE AIR CONDITIONING SYSTEM WITH REFRIGERANT
Perform vacuum purging using a vacuum pump or appropriate equipment.
Charge the air conditioning system with refrigerant.
| Refrigerant type |
|---|
| HFC-134a (R134a) |
| Standard charge amount |
|---|
| 470 g (16.6 oz.) |
Note
Do not turn the A/C switch on before charging the air conditioning system with refrigerant. Doing so may cause the compressor to work without refrigerant, resulting in overheating of the compressor.
The refrigerant amount should be checked by quantity (weight).
The graph above is shown for reference only. This vehicle is not equipped with a sight glass.
If at all possible, avoid using a manifold gauge set or recovery and recycling unit that has been used for vehicles with conventional compressor oil (ND-OIL 8 or equivalent). If either of these is used, conventional compressor oil remaining in the equipment will enter the air conditioning system of the vehicle, resulting in electrical insulation performance deterioration. A manifold gauge set that has been used 3 times or less can be used if an appropriate one is not available.
Tech Tips
Ensure that sufficient refrigerant is available to recharge the system when using a refrigerant recovery unit. Refrigerant recovery units are not always able to recover 100% of the refrigerant from an air conditioning system.
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 stored.
| DTC No. | Detection Item |

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.) |
When using the intelligent tester:
Connect the intelligent tester 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 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. |
Tech Tips
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.
When not using the intelligent tester:
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 reserve tank improves. |
Tech Tips
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.
After the air is completely bled from the cooling system, tighten the reserve tank cap.
Add coolant to the full line of the reserve tank.
INSPECT FOR COOLANT LEAK (for Inverter)
Remove the reserve tank cap.
CAUTION:
To avoid the danger of being burned, do not remove the reserve tank cap while the coolant for the inverter is still hot.
Install a radiator cap tester.
Pump the radiator cap tester to 122 kPa (1.2 kgf/ cm2, 18 psi), and then check that the pressure does not drop.
Tech Tips
If the pressure drops, check the hoses, radiator, inverter water pump assembly, inverter with converter, and hybrid vehicle transaxle assembly for leaks.
Reinstall the reserve tank cap.
WARM UP COMPRESSOR
Keep the A/C switch on for at least 2 minutes to warm up the compressor.
Note
To prevent damage to the compressor, be sure to warm up the compressor when turning the air conditioning on after removing and installing air conditioning system lines (including the compressor).
INSPECT FOR REFRIGERANT LEAK
After recharging the air conditioning system with refrigerant, inspect for refrigerant leaks using a halogen leak detector.
Carry out the test under the following conditions:
Power switch off.
Secure good ventilation (the halogen leak detector may react to volatile gases which are not refrigerant, such as gasoline vapor and exhaust gas).
Repeat the inspection 2 or 3 times.
Measure the pressure to make sure that there is some refrigerant remaining in the air conditioning system.
Pressure when the compressor is off: approx. 392 to 588 kPa (3.9 to 5.9 kgf/cm2, 57 to 85 psi)
| *1 | Halogen Leak Detector |
| *a | Inspect for Leak |
Using a halogen leak detector, inspect for refrigerant leaks from the air conditioning system.
| *1 | Halogen Leak Detector |
| *2 | Drain Hose |
Bring the halogen leak detector close to the drain hose with the detector power off, and then turn the detector on.
Tech Tips
After the blower motor has stopped, leave the cooling unit for more than 15 minutes.
Bring the halogen leak detector sensor under the drain hose.
When bringing the halogen leak detector close to the drain hose, make sure that the halogen leak detector does not react to volatile gases. If it is not possible to avoid interference from volatile gases, the vehicle should be lifted up to allow checking for leaks.
If a refrigerant leak is not detected from the drain hose, remove the blower motor control from the cooling unit. Insert the halogen leak detector sensor into the unit and check for a leak.
Disconnect the pressure sensor connector and leave it for approximately 20 minutes. Bring the halogen leak detector close to the pressure sensor and check for a leak.
Tech Tips
When checking for leaks, the presence of oily dirt at a joint can indicate a leak.
