2. INSPECT HYBRID TRANSAXLE FLUID

(a) Make sure that the vehicle will remain level, and lift the vehicle.

(b) Using a 10 mm union nut wrench and 10 mm straight hexagon, remove the filler plug and gasket from the rear traction motor with transaxle assembly.

*1 10 mm Union Nut Wrench *2 10 mm Straight Hexagon

(c) Check that the hybrid transaxle fluid level is between 0 to 5 mm (0 to 0.196 in.) from the bottom lip of the filler plug opening. (If the hybrid transaxle fluid level is too low, return to the Add Hybrid Transaxle Fluid procedure.) NOTICE: 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.

*1 Filler Plug *a 0 to 5 mm (0 to 0.196 in.)

(d) 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.)
