      • 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.

    2. 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 5 mm (0 to 0.197 in.) from the bottom lip of the filler plug opening. (If the fluid level is too low, return to the Add Hybrid Transaxle Fluid procedure.)

      Note

      After adding fluid, make sure to check the fluid level.
