      Text in Illustration
      *1 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.

      Note


      • Stop the vehicle on a level surface.

      • Recheck the transaxle fluid level after driving following fluid replacement.

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

      • 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 fully insert the filler nozzle into the filler plug opening.

      Reference
      3.4 liters (3.6 US qts, 3.0 lmp.qts)
      Fluid Type
      Toyota Genuine ATF WS

  27. INSPECT HYBRID TRANSAXLE FLUID


    1. A003UXW

      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 is insufficient, return to the Add Hybrid Transaxle Fluid procedure.)

      Note


      • Stop the vehicle on a level surface.

      • Recheck the transaxle fluid level after driving following fluid replacement.

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

      • 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.

    2. Check for leaks if the quantity of transaxle fluid is low.

    3. Using a 10 mm hexagon socket wrench, install the filler plug with a new gasket.

      Torque:
      50 N*m  { 510 kgf*cm, 37 ft.*lbf }
