   1. Lift the vehicle. [*1]

      Note:

      The transmission fluid level cannot be measured accurately if the vehicle is not level. Make sure it is held level.

   2. 

      Remove the drain plug and gasket from the hybrid vehicle transmission assembly and drain the transmission fluid. [*2]

   3. Temporarily install the gasket and the drain plug to the hybrid vehicle transmission assembly. [*3]

      Tip:

      Gasket replacement and tightening are performed at step [*17].

   4. 

      Remove the refill plug and gasket from the hybrid vehicle transmission assembly. [*4]

      CAUTION:

      Make sure not to touch the high temperature parts such as the exhaust pipe, etc.

   5. 

      Using a 5 mm hexagon socket wrench, remove the overflow plug and gasket from the hybrid vehicle transmission assembly. [*5]

   6. 

      Add transmission fluid to the refill hole until it flows out of the overflow hole. [*6]

      Note:
      

      • Use Toyota Genuine ATF WS.

      • Be sure to add transmission fluid slowly. If transmission fluid is added quickly, the transmission fluid may hit internal parts and bounce back, resulting in transmission fluid coming out of the refill hole.

   7. 

      Wait until the transmission fluid flow slows and only drips come out. [*7]

   8. 

      Using a 5 mm hexagon socket wrench, temporarily install the overflow plug and gasket to the hybrid vehicle transmission assembly. [*8]

      Pour the specified amount of transmission fluid into the refill hole. [*9]

      Specified Amount of Fluid
      1.6 liters (1.7 US qts, 1.4 Imp. qts)

      Note:

   10. 

       Temporarily install the gasket and the refill plug to the hybrid vehicle transmission assembly. [*10]
