ELECTRICAL ELECTRICAL Low Voltage Disconnect (LVD) Electrical System Purpose See an authorized dealer if the LVD fails to reconnect loads during normal operation. WARNING! The LVD may increase battery life and prevent unnecessary jump start conditions by ensuring that an unattended load does not deplete the battery charge to a level that will prevent you from starting your vehicle. Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
