Automatic Transaxle Fluid (ATF) Level Check

NOTE: When checking the ATF level, be careful not to allow foreign substance (like dust) to enter through the filler hole.

Shut off the high voltage circuit.
(Refer to Automatic Transaxle System - "HIGH VOLTAGE SHUTOFF PROCEDURE ")
Remove the under cover.
(Refer to Engine Mechanical System - "ENGINE ROOM UNDER COVER ")
Drain the coolant of hybrid motor cooling system.
(Refer to Hybrid Motor System - "COOLANT ")
Remove the air cleaner assembly and air duct.
(Refer to Engine Mechanical System - "AIR CLEANER ")
Remove the hybrid power control unit (HPCU) assembly.
(Refer to Hybrid Control System - "HYBRID POWER CONTROL UNIT ")
Add 0.7 liters of ATF SP-IV through the ATF filler hole after removing the eyebolt (A).

Start the engine to warm up the ATF.
NOTE: Do not step on the brake and accelerator simultaneously to warm up the ATF.
Check by using KDS/GDS that the temperature of the ATF is between 50°C and 60°C (122-140°F).
Move the shift lever slowly from "P" to "D", then back to "P". Repeat this sequence a total of two times and then move the shift lever to "P" range.
NOTE: Pause in each range for more than 2 seconds.
Lift the vehicle and remove the ATF level check plug (A) from the valve body cover.

NOTE: When removing the ATF level plug, keep the vehicle on a level ground.
Check the ATF level.
Normal: ATF flows out in a thin oil stream.

Excessive (abnormal): Over 0.9 liters of ATF flows out for 2 minutes.

Insufficient (abnormal): There is no fluid flow.
NOTE:
If the ATF level is too high or low, follow the instructions below.
- Excessive: Drain until the ATF flows out in a thin oil stream.
- Insufficient: Add until the ATF flows out in a thin oil stream.
Install the ATF level check plug (A).
