      Tech Tips


      • After disconnecting and reconnecting the auxiliary battery cable, the hybrid control system may not start on the first attempt. If this occurs, turn the power switch off. The hybrid control system will start normally from the second time onward.

      • When the auxiliary battery cable is disconnected and reconnected, the power source mode returns to the mode it was in before the auxiliary battery cable was disconnected.
