Adjustment [09/2023 - ]: Procedure
WARNING: This page is about a different car, the 2024 Lexus TX 550h+ and 2024 Lexus TX 500h. However, it is still accessible from the selected car via links, so may be relevant.
- DRAIN HYBRID TRANSAXLE FLUID
- Remove the filler plug and gasket from the rear transaxle with motor and inverter assembly.
- Using a 10 mm hexagon socket wrench, remove the drain plug and gasket from the rear transaxle with motor and inverter assembly and drain the hybrid transaxle fluid.
- Using a 10 mm hexagon socket wrench, install the drain plug and a new gasket to the rear transaxle with motor and inverter assembly.
Torque: 50 N.m (510 kgf/cm, 37 ft.lbf)
- Temporarily install the gasket and filler plug to the rear transaxle with motor and inverter assembly.
HINT:
Because the filler plug will be removed again, the gasket can be reused at this time.
- Remove the filler plug and gasket from the rear transaxle with motor and inverter assembly.
- ADD HYBRID TRANSAXLE FLUID
- Remove the filler plug and gasket from the rear transaxle with motor and inverter assembly.
- Add hybrid transaxle fluid until the hybrid transaxle fluid level is between 0 to 7 mm (0 to 0.276 in.) from the bottom lip of the filler plug opening. [#]
*a Filler Nozzle *b 0 to 7 mm (0 to 0.276 in.) Hybrid Transaxle Fluid Standard Capacity (for Reference)
3.1 liters (3.3 US qts, 2.7 Imp. qts)
NOTE:- Use Toyota Genuine e-Transaxle Fluid TE.
Using hybrid transaxle fluid other than the above type may cause abnormal noise or vibration, or ultimately damage the transaxle of the vehicle.
- Be sure to fully insert the filler nozzle into the filler plug opening.
- Be sure to add hybrid transaxle fluid slowly. If hybrid transaxle fluid is added quickly, the hybrid transaxle fluid may hit internal parts and bounce back, resulting in hybrid transaxle fluid coming out of the filler plug opening.
- Be sure to directly check that the hybrid transaxle fluid level is within the specified range.
- Driving the vehicle with an insufficient or excessive amount of hybrid transaxle fluid may damage the rear transaxle with motor and inverter assembly.
- Use Toyota Genuine e-Transaxle Fluid TE.
- After adding hybrid transaxle fluid, leave the vehicle for 30 seconds so that the hybrid transaxle fluid surface can become still again, and then check that the hybrid transaxle fluid level is between 0 to 7 mm (0 to 0.276 in.) from the bottom lip of the filler plug opening. (If the hybrid transaxle fluid level is low, repeat this procedure from step [#].)NOTE:
After adding hybrid transaxle fluid, make sure to check the hybrid transaxle fluid level.
