    3. After the auxiliary battery is removed and reinstalled, open and close the driver door, and be sure to wait 10 seconds or more before the next hybrid control system start. The hybrid control system may not start immediately after the auxiliary battery is reinstalled.

      • 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.
