      Add transaxle fluid until the fluid level is between 0 to 5 mm (0 to 0.197 in.) from the bottom lip of the filler plug opening.

      Note


      • Stop the vehicle on a level surface.

      • Use Toyota Genuine ATF WS.

      • Be sure to fully insert the filler nozzle into the filler plug opening.

      • 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.

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

      • Insufficient or excessive amounts of transaxle fluid may damage the hybrid transaxle.

      Reference
      3.7 liters (3.9 US qts, 3.2 Imp. qts)

      Note


      • Stop the vehicle on a level surface.

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

      • Insufficient or excessive amounts of transaxle fluid may damage the hybrid transaxle.
