CAUTION / NOTICE / HINT
CAUTION:
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.

PROCEDURE
1. DRAIN COOLANT (for Inverter)
CAUTION:
To
avoid the danger of being burned, do not remove the reserve tank cap
while the coolant (for inverter) is still hot. Pressurized, hot coolant
(for inverter) and steam may be released and cause serious burns.
NOTICE:
- Do not reuse the drained coolant because it may contain foreign matter.
- 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.
(a) Remove the reserve tank cap from the inverter reserve tank assembly.
(b) Remove the 2 screws and clip. | |
(c) Pull down the No. 1 engine under cover.
NOTICE:
Do not damage the No. 1 engine under cover.
(d) Connect a hose with an inside diameter of 8.3 mm (0.327 in.) to the drain cock as shown in the illustration. |

(e) Loosen the drain cock plug indicated in the illustration and drain the coolant. |
|
(f) Tighten the drain cock plug by hand.
(g) Disconnect the hose from the drain cock.
(h) Install the 2 screws and clip.
2. ADD COOLANT (for Inverter)
NOTICE:
- Do not reuse the drained coolant because it may contain foreign matter.
- If the vehicle is driven with air in the inverter cooling system, damage may occur and the following DTCs may be stored.

(a) Slowly pour coolant into the inverter reserve tank assembly until it reaches the FULL line.
Standard Capacity: 1.8 liters (1.9 US qts, 1.6 Imp. qts) NOTICE:
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. | |
(b) When using the Techstream:
(1) Connect the Techstream to the DLC3.
(2) Turn the power switch on (IG).
(3) 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 |
(4)
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.
(c) When not using the Techstream:
(1) Turn the power switch on (READY). [*1]
(2) Turn the power switch off and add coolant to the FULL line as the coolant level will drop as the air bleeds. [*2]
NOTICE:
- 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.
(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 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.
(d)
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. NOTICE: Check that the amount of coolant (for Inverter) added is more than the amount drained. |
