The oil pump will operate to circulate hybrid transmission fluid through the oil cooler system.
Lift the vehicle. [*1]
Turn the power switch off, wait for 1 minute, and then remove the refill plug and gasket from the hybrid vehicle transmission assembly. [*2]
Note
After the power switch is turned off, hybrid transmission fluid will flow back from the oil cooler system to the hybrid vehicle transmission assembly and the fluid level will rise. Make sure to perform steps [*1] to [*5] within 20 minutes.
| *a | 0 to 5 mm (0 to 0.196 in.) |
Add hybrid transmission fluid until the fluid level is between 0 to 5 mm (0 to 0.196 in.) from the bottom lip of the refill plug opening. [*3]
Note
Use Toyota Genuine ATF WS.
Be sure to fully insert the filler nozzle into the refill plug opening.
Be sure to add hybrid transmission fluid slowly. If hybrid transmission fluid is added quickly, the hybrid transmission fluid may hit internal parts and bounce back, resulting in fluid coming out of the refill plug opening.
An insufficient or excessive amount of hybrid transmission fluid may damage the hybrid vehicle transmission assembly.
Make sure that the hybrid transmission fluid temperature is 5°C (41°F) or more.
After adding hybrid transmission fluid, leave it for 30 seconds so that the fluid surface can become still again, and then check that the fluid level is between 0 to 5 mm (0 to 0.196 in.) from the bottom lip of the refill plug opening. [*4]If the fluid level is too low, add hybrid transmission fluid.
