Extrication
Extrication
Immobilize Vehicle
- Chock wheels and set the parking brake.
- Push the P switch to engage park.
Disable Vehicle
- Performing either of the two procedures will shut the vehicle off and disable the HV battery pack, SRS airbags, and gasoline fuel pump, and optional remote air conditioning system.
Procedure #1
1. Confirm the status of the READY indicator in the instrument cluster. If the READY indicator is illuminated, the vehicle is on and operational.
2. Shut off the vehicle by pushing the power button once.
3. The vehicle is already shut off if the instrument cluster lights are not illuminated. Do not push the power button because the vehicle may start.
4. If the smart key is easily accessible, keep it at least 16 feet (5 meters) away from the vehicle.
5. Disconnect the 12 Volt auxiliary battery under the cover in the cargo area to prevent accidental restarting of the vehicle and operation of the optional remote air conditioning system.
Procedure #2 (Alternate if power button is inaccessible)
1. Open the hood.
2. Remove the fuse box cover.
3. Remove the IGCT fuse (30A green colored) and AM2 fuse (7.5A orange colored) in the engine compartment fuse box (refer to illustration). If the correct fuse cannot be recognized, pull all fuses in the fuse box.
4. Disconnect the 12 Volt auxiliary battery under the cover in the cargo area.
NOTE:
Before disconnecting the 12 Volt auxiliary battery, if necessary, lower the windows, unlock the doors and open the hatch as required. Once the 12 Volt auxiliary battery is disconnected, power controls will not operate.
WARNING:
- The high voltage system may remain powered for up to 10 minutes after the vehicle is shut off or disabled. To prevent serious injury or death from severe burns or electric shock, avoid touching, cutting, or breaching any orange high voltage power cable or high voltage component.
- The SRS may remain powered for up to 90 seconds after the vehicle is shut off or disabled. To prevent serious injury or death from unintentional SRS deployment, avoid breaching the SRS components.
- If none of the disabling procedures can be performed, proceed with caution as there is no assurance that the high voltage electrical system, SRS, fuel pump, or optional remote air conditioning system are disabled.
Stabilize Vehicle:
Crib at (4) points directly under the front and rear pillars.
Do not place cribbing under the high voltage power cables, exhaust system, or fuel system.
NOTE: The Prius is equipped with a tire pressure warning system that by design prevents pulling the metal valve stem with integral transmitter from the wheel. Snapping the valve stem with pliers or removing the valve cap and schrader valve will release the air in the tire.
Access Patients:
Glass Removal
Use normal glass removal procedures as required.
SRS Awareness:
Responders need to be cautious when working in close proximity to undeployed airbags and seat belt pretensioners. Deployed front dual stage airbags automatically ignite both stages within a fraction of a second.
Door Removal/Displacement:
Doors can be removed by conventional rescue tools such as hand, electric, and hydraulic. In certain situations, it may be easier to pry back the body to expose and unbolt the hinges.
Roof Removal:
The Prius is equipped with side curtain airbags. If the side curtain airbags are undeployed, total roof removal is not recommended. This is to avoid breaching the side curtain airbags, inflators, and wiring harness. Patient access through the roof can be performed by cutting the roof center section inboard of the roof rails as illustrated.
Prius models equipped with the optional solar panel have an output wire bundled with the side curtain airbag wire harness routed along the driver side C-pillar as shown in the illustration. This output wire is energized when the solar panel surface is exposed to light energy, and similar to a 12 Volt battery positive cable, it cannot be shut off or isolated until it reaches the control computer under the dashboard.
Cutting the roof center section may result in cutting into the optional solar panel and energized output wire. Wear personal protective equipment to prevent exposure to broken glass, material fragments, and dust.
NOTE: The 27 Volt maximum solar panel output wire has a higher arc potential than 12 Volt wires.
If the driver side curtain airbag is undeployed, avoid cutting the shaded area shown in the illustration. If this area is cut, there is a slight possibility of shorting the side curtain airbag harness and the solar panel energized output wire, resulting in airbag deployment. If cutting this area is unavoidable, manually disable the solar panel output wire using one or both of the following recommendations.
- Disable solar panel output by covering the entire panel with a material that blocks sunlight. Debris bags or salvage covers have been effective for disabling the solar panel output when two layers, either two separate layers, or one layer folded over the other, are used. Make sure the material is free of holes or tears that would allow sunlight through, and block the entire solar panel since even a small amount of sunlight will allow the solar panel to generate power.
NOTE: Once the solar panel is disabled, the output in the energized wire drops immediately.
- Disable solar panel output by disconnecting or cutting the solar panel energized output wire. Remove the headliner above the driver side rear passenger area. Identify the red or blue output wire from under the solar panel as illustrated. Disconnect the connector or cut the red or blue wire to disable power output.
NOTE: The 27 Volt maximum solar panel output wire has a higher arc potential than 12 Volt wires.
If neither of the above recommendations can be performed, keep away from the side curtain airbag deployment zone area along the driver and passenger side window as shown in the illustration.
Dash Displacement:
The Prius is equipped with side curtain airbags. When undeployed, total roof removal is not recommended. This is to avoid breaching the side curtain airbags, inflators, SRS harnesses, and optional solar panel energized wire. As an alternative, dash displacement may be performed by using a Modified Dash Roll.
Rescue Lift Air Bags:
Responders should not place cribbing or rescue lift air bags under the high voltage power cables, exhaust system, or fuel system.
Repositioning Steering Wheel and Front Seats:
Telescopic steering wheel and seat controls are shown in the illustrations.
Active Headrest Removal:
The Prius is equipped with active front headrests, located in both front seatbacks. The active headrests are mechanical non-pyrotechnic head supports that are designed to reduce neck injuries in the event of a rear collision.
No special methods are required to remove the headrests. Push the release button and lift to remove the headrest.
NOTE:
The Prius is equipped with an optional electrochromic auto dimming rear view mirror. The mirror contains a minimal amount of transparent gel sealed between two glass plates that will not normally leak.
