   *a	Filler Nozzle
   *b	0 to 10 mm (0 to 0.394 in.)

   Hybrid Transaxle Fluid Standard Capacity (for Reference)

   4.0 liters (4.2 US qts, 3.5 Imp. qts)

   NOTE:

   • When adding hybrid transaxle fluid, make sure that the vehicle is level.
   • Use Toyota Genuine ATF WS.

     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 hybrid vehicle transaxle assembly.
3. 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 10 mm (0 to 0.394 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.

4. Using a 10 mm hexagon socket wrench, temporarily install the filler plug and gasket to the hybrid vehicle transaxle assembly.

   HINT: 

   Reuse the old gasket as the filler plug will be removed again.
