  • Supplemental Restraint Systems
  • Identifying and Disabling Voltage

The following list describes certain features that have been incorporated into 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.
  • 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 60C (140F), thermal sensors located near the HV battery will automatically disconnect the HV battery.
