2-5 High-voltage Safety System
The
high-voltage safety system is intended to help keep vehicle occupants and emergency responders safe
from high-voltage electricity. • A high-voltage fuse provides short circuit protection inside the high-voltage battery.
• The high-voltage safety system is insulated from the metal chassis.
• Positive and negative high-voltage power cables are connected to the high-voltage battery and arecontrolled by normally open system main relays (SMR1 and SMR2) . When the vehicle is shut off,
the relays stop electrical flow from leaving the high-voltage battery. However, it can take
approximately ten (10) minutes for the high-voltage capacitor to fully discharge. Trunk

Pull underhood fuse panel (1) out by hand and
disconnect terminal (black) connector (A) .
NOTE: : Arrow in illustration depicts vehicle front
direction.
6.
If you cannot identify the connector, disconnect all
connectors on the underhood fuse panel. To avoid unintended reinstallation and risk of electrical shock and severe personal injury or
death,
the rescuer should cover the fuse box and connectors with insulated tape or remove
the fuse panel and carry on his/her person.
