  The engine starts.
  
  HINT:
  - Do not turn the power switch on (READY) and off repeatedly because this may cause DTC P3000-389 to be set.
  - Turning the power switch on (READY) and off repeatedly while the SOC is low may cause the SOC to drop further, resulting in DTC P3000-389 being set. Charge the HV battery using the THS charger as necessary.
  - Cranking the engine once causes the SOC to drop approximately 1%.
  - Charging the HV battery once (10 minutes) using the THS charger restores the SOC approximately 2%.
NO → CHARGE HV BATTERY (CHECK THAT ENGINE STARTS)

YES → LEAVE VEHICLE IN P POSITION, AND CHARGE HV BATTERY IN IDLE STATUS UNTIL IDLING STOPS
