   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 hybrid transaxle fluid coming out of the filler plug opening.
   • Be sure to directly check that the hybrid transaxle fluid level is within the specified range.
   • Driving the vehicle with an insufficient or excessive amount of hybrid transaxle fluid may damage the hybrid vehicle transaxle assembly.
