Torque: 39 N*m (398 kgf*cm, 29 ft.*lbf)
  2. ADD HYBRID TRANSAXLE FLUID Add transaxle fluid until the fluid level reaches the bottom lip of the filler plug opening. NOTE: Keep the transaxle fluid temperature at 5°C (41°F) or higher. Stop the vehicle on a flat road. Recheck the transaxle fluid level after driving when exchanging transaxle fluid. Insufficient or excessive amounts of transaxle fluid may be the cause of some trouble. Reference 4.2 liters (4.4 US qts, 3.7 lmp.qts) Using a 10 mm hexagon socket wrench, temporarily tighten the filler plug with gasket.
  3. INSPECT AND ADJUST HYBRID TRANSAXLE FLUID Put the engine in inspection mode. Refer to «INSPECTION MODE PROCEDURE»(ref-398089-S21258796492011051600000) . After waiting for 1 minute or more, stop the engine. Using a 10 mm hexagon socket wrench, remove the filler plug and gasket. Add transaxle fluid. Check that the fluid level is between 0 to 5 mm (0 to 0.197 in.) from the bottom lip of the transaxle filler plug opening. NOTE: Keep the transaxle fluid temperature at 5°C (41°F) or higher. Stop the vehicle on a flat road. Recheck the transaxle fluid level after driving when exchanging transaxle fluid. Insufficient or excessive amounts of transaxle fluid may be the cause of some trouble. Check for leaks if the quantity of transaxle fluid is low. Using a 10 mm hexagon socket wrench, install the filler plug with a new gasket. Torque: 39 N*m (398 kgf*cm, 29 ft.*lbf)
