   NOTE:

   • Stop the vehicle on a level surface.
   • Be sure to directly check that the hybrid transaxle fluid level is within the specified range.
   • An insufficient or excessive amount of hybrid transaxle fluid may damage the rear traction motor with transaxle assembly.
   • If the hybrid transaxle fluid was replaced or hybrid transaxle fluid was added, make sure to recheck the hybrid transaxle fluid level after driving the vehicle.
4. Check for leaks if the hybrid transaxle fluid level is low. (If there are no hybrid transaxle fluid leaks but the amount of the hybrid transaxle fluid is insufficient, add hybrid transaxle fluid.)
