   NOTICE:

   1. Stop the vehicle on a level surface.
      
   2. Use Toyota Genuine ATF WS.
      
   3. Be sure to fully insert the filler nozzle into the filler plug opening.
      
   4. Be sure to add fluid slowly. If fluid is added quickly, the fluid may hit internal parts and bounce back, resulting in fluid coming out of the filler plug opening.
      
   5. Be sure to directly check that the transaxle fluid level is within the specified range.
      
   6. Insufficient or excessive amounts of transaxle fluid may damage the hybrid transaxle.
      

   Reference:

   3.4 liters (3.6 US qts, 3.0 lmp.qts)
   

2. After adding 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 10 mm (0 to 0.394 in.) from the bottom lip of the filler plug opening. (If the fluid level is too low, return to the Add Hybrid Transaxle Fluid procedure.)
   

   NOTICE:

   After adding fluid, make sure to check the fluid level.

1. Using a 10 mm hexagon socket wrench, remove the filler plug and gasket.
