High Voltage Safety
Information
eAssist vehicles have a standard
12-volt battery and a high voltage
battery. Only a trained service
technician with the proper
knowledge and tools should inspect,
test, or replace the high voltage
battery. See your dealer if the high
voltage battery needs service.
The negative 12-volt battery cable
and the high voltage cable in the
engine compartment are clearly
labeled. In emergency situations,
first responders can cut those
cables to disable the high voltage
battery system.
