2-3 High Voltage Circuit Shut-Off System
The high voltage can be shut off by the following methods:
Service plug Positioned in the center area of the Li-ion battery, this shuts off output high
voltage when manually removed.
System main relay (located
in high voltage battery) Controlled by the power switch, this relay, which is controlled by the 12V
system, shuts off the high voltage from the Li-ion battery.
Emergency shut-off sys-
tem In the case of a collision (front and side collisions in which the air bags are
deployed, certain rear collisions) or certain system malfunctions this system
is designed to shut off the high voltage from the Li-ion battery.
Charging connector Some of the high voltage components are activated during charging. Remove
the charging connector to deactivate these components.
2-4 Preventing Electrical Shock
1. If it is necessary to touch any of the high voltage harnesses or components, you must always
wear appropriate Personal Protective Equipment (PPE)
(refer to
3-2 Preparation Items (DG–15) ) and shut off the high voltage system by referring
to 3-4 High Voltage System Shut-Down Procedures (DG–16) .
2. To avoid the risk of electrocution, NEVER touch the inside of the Li-ion battery unless appropriate
PPE is worn even after shutting off the high voltage system. The Li-ion battery maintains charge
even though the high voltage system is shut down.
3. Cover any damaged high voltage components with insulated tape.
