   1. Be sure that the vehicle remains level and lift the vehicle. [*1]

   2. 

      *1	Filler Plug

   3. Using a 10 mm hexagon socket wrench, remove the drain plug and gasket from the hybrid vehicle transaxle assembly. [*3]

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

      Tech Tips

   5. 

      *1	Filler Plug
      *2	Filler Nozzle

      Add transaxle fluid until the fluid level is between 0 to 10 mm (0 to 0.394 in.) from the bottom lip of the filler plug opening. [*5]

      Note

      
      

      • Use Toyota Genuine ATF WS.

      • 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 fluid coming out of the filler plug opening.

      • Be sure to directly check that the fluid level is within the specified range.

      • An insufficient or excessive amount of hybrid transaxle fluid may damage the hybrid vehicle transaxle assembly.
