System Operation

This vehicle is equipped with 12 volt battery where the high voltage battery has a high voltage to low voltage energy transfer feature that keeps the 12 volt battery charged.

When the 12 volt battery's voltage is low the high voltage battery transfers the energy to charge the 12 volt battery when the vehicle is off. The high voltage battery needs to be de-energized when servicing the 12 volt battery.
