HIGH-VOLTAGE ELECTRICAL AND FUEL DISCONNECT FEATURES
The following list describes certain features that have been incorporated into the
Hybrid vehicles that allow for either simple or automatic shutoff of the high-
voltage electrical and fuel systems.
•
Inertia Switch – Fuel Pump Shut-Off — The fuel pump shut-off inertia
switch is normally closed to allow vehicle operation. In the event of a
collision or a substantial physical jolt, the switch is designed to open
automatically shutting off electrical power to the fuel pump and the HV
shut-off switch.
•
Inertia Switch – High-Voltage (HV) Shut-Off — The HV shut-off switch
is located behind the jack access panel in the cargo area on the
passenger side of the vehicle. In the event of a collision or a substantial
physical jolt, the switch is designed to open automatically disabling the
HV system.
•
High-Voltage (HV) Fuse — In the event of a high current short circuit,
the HV fuse will open disabling the HV system.
•
High-Voltage (HV) Interlock Circuit — Whenever a high-voltage
connector is disconnected, the HV interlock circuit opens and disables
the HV system.
•
Ignition Key in OFF Position — Anytime the ignition lock cylinder is in
the OFF position, the HV system is disabled.
•
High-Voltage Service Disconnect Switch — Whenever the high-voltage
service disconnect switch (located on top of the high-voltage battery in
the cargo area) is removed, the HV system is disabled. For additional
information, refer to Page 9 in this manual.
•
Thermal Sensors — In the event the ignition key is left in the ON
position, while the vehicle is parked and the HV battery temperature
exceeds 60°C (140°F), thermal sensors located near the HV battery will
automatically disconnect the HV battery.
