СИСТЕМА CVT


  1. OUTLINE


    1. A K115 Continuously Variable Transaxle (CVT) is used.

    2. A 7-speed sport sequential shiftmatic system is used.

    3. A gate type shift lever is used.

    4. A CVT fluid warmer is used in the CVT fluid cooling system.

    5. A coaxial 2 discharge port oil pump system is used.

    6. An electric CVT oil pump (oil pump with motor assembly) is provided to ensure adequate CVT oil pressure when the stop and start system is operating. For details, refer to IDLING STOP CONTROL.
