GPF RegenerationThis procedures is to forcibly regenerate the GPF with scan tool when the GPF doesn't have been regenerated during driving. For example, if the vehicle has repeated "Low speed driving" or "Short distance driving", the GPF regeneration procedure cannot be proceeded because "Regeneration Mode" doesn't made.
Safety PrecautionPrecautions To Take Before Servicing High Voltage System • Since hybrid vehicles contain a high voltage battery, if the high voltage system or vehicles are handled incorrectly, this might lead to a serious accidents like electric shock and electric leakage.
