High Voltage Battery

The High Voltage battery gradually discharges when the vehicle is not in use. As a
result, if your vehicle is parked for an extended period of time, the battery level may
get low. Keeping the High Voltage battery's charge level low can shorten its life.
To maintain the High Voltage battery, drive your vehicle for more than 30 minutes
to recharge it at least once every three months. Also, try to park in shaded areas
instead of direct sunlight.
