Preventing Current Flow Through the High-Voltage Cables

Before attempting to rescue occupants or move a damaged Civic Hybrid, you should reduce the potential of current flowing from the electric motor or the high-voltage battery through the high-voltage cables.

There are two recommended methods for preventing current flow. These are discussed in the following pages:
PREFFERED METHOD for High-Voltage Shutdown
Push and hold the POWER button for 3 seconds.
This simple action turns the vehicle OFF and immediately shuts down the highvoltage system controllers, preventing current flow into the cables. It also cuts power to the airbags and front seat belt tensioners, though these pyrotechnic devices have up to a 3-minute deactivation time.

To prevent accidental restarting, you must remove the keyless remote from the vehicle and move it at least 20 feet away.

If you cannot locate the keyless remote, disconnect the negative terminal from the 12-volt battery to prevent electrical fires and accidental restarting of the vehicle.

ALTERNATIVE BEST METHOD for High-Voltage Shutdown
Locate and cut the negative 12-volt battery cable and the Power Control Unit (PCU) cable in the engine compartment.
Cutting both the negative 12-volt battery cable and PCU cable immediately turns off and shuts down the high-voltage system controllers and engine, preventing current flow into the high-voltage cables.

1. Pull the hood release handle under the driver's side lower corner of the dashboard. The hood will open slightly.
   

2. Push the hood latch lever (located under the front edge of the hood to the center) to the side and raise the hood. Once you have raised the hood slightly, you can release the lever.
   

3. Remove the support rod from the clamp using the grip. Mount the support rod in the hood.
   

If you need to cut the hood to open it, be sure to stay within the cut zone as shown

4. Locate the two cut point labels as shown, and cut them.

If touching high-voltage cables and/or other high-voltage components is unavoidable, personal protective equipment (insulating gloves, goggles, and boots) should always be worn.
This also cuts power to the airbags and the front seat belt tensioners, but remember these pyrotechnic devices have up to a 3-minute deactivation time.
NOTE: When cutting the cables, do not allow the cutting tool to contact any surrounding metal parts; electrical arcing could occur, igniting any flammable vapors.
If you cannot do either method to stop the engine and prevent current flow into the highvoltage cables, use extreme care and do not touch damaged cables as they may be electrically charged.

Access to Occupants

High-Strength and Ultra-High-Strength Steel

The body of the Civic Hybrid is made of high-strength steel and ultra-high-strength steel indicated in the colored areas.

Extricating Occupants

If you need to cut the hood to open it, be sure to stay within the cut zone as shown.

When cutting the vehicle body, personal protective equipment (insulating gloves, goggles, and boots) should always be worn.

If you need to cut the vehicle body or use Jaws-of-Life equipment to remove occupants, be sure to stay within the cut zone as shown.

Emergency Towing

The preferred method for emergency towing is to use a flat-bed tow truck. If wheel lift equipment must be used, be sure to suspend the front wheels and release the parking brake. DO NOT use cable-type tow equipment.

NOTE: If there is a 12-volt power failure, the vehicle cannot be shifted into neutral. Use available wheel dollies.

Flat-Bed

1. Secure the vehicle on the flat-bed tow truck.
2. Apply the parking brake.

Front Wheel Type

1. Lift the front wheels.
2. Release the parking brake.

Cable-type

Never tow this vehicle with cable-type equipment.

Be aware that when rolling a Civic Hybrid with the front (drive) wheels on the ground, the electric motor can produce electricity and remains a potential source of electric shock even when the high-voltage system is turned off.

Carry a fire extinguisher during transportation for enhanced safety, and have the flat-bed tow truck with the damaged vehicle followed by another support vehicle for monitoring. After transportation, discharge the battery if necessary. See the Battery Discharging information on this section.

If the orange high-voltage cables or high-voltage covers have been damaged exposing wiring, terminals, and/or other components, the exposed parts should never be touched. Doing so could result in serious injury or death due to severe burns or electric shock. If it is not clear whether the exposed wires and terminals are high-voltage components or not, do not touch them.

If touching high-voltage cables and/or other high-voltage components is unavoidable, personal protective equipment (insulating gloves, goggles, and boots) should always be worn.

Acoustic Vehicle Alerting System
The Civic Hybrid is equipped with an acoustic vehicle alerting system that alerts pedestrians with an audible sound that it is approaching when the speed is about 14 mph or less. When pushing the Civic Hybrid with the ignition turned to ON, you will hear this sound as the vehicle is being moved.

Lifting the Vehicle

Use the indicted lifting points to raise the vehicle.

Securing the Vehicle

The recommended tie-down locations for securing the vehicle are indicated below.

• Four tie-down slots (covered by rubber plugs) - Two behind the front wheels and two in front of the rear wheels
  

Dimensions & Weight

Storing the Vehicle

The damaged vehicle can be stored in either Open Perimeter Isolation or Barrier Isolation.

Open Perimeter Isolation
Store the vehicle in an outdoor area separated from all combustibles and structures by a minimum distance of 50 feet (15.2 m) from all sides.

Barrier Isolation

• Store the vehicle in an outdoor area separated from all combustibles and structures with a barrier constructed of earth, steel, concrete or solid masonry designed to contain a fire or prevent the fire from extending to adjacent vehicles.
• The barriers should be of sufficient height to direct any flame or heat away from adjacent vehicles.
• If the barrier is only on three of the four sides of the vehicle, the open side must maintain the separation distance referenced above.
• It is not recommended to fully enclose the vehicle in a structure due to the risk of post-incident fire extending to the structure and the possibility of trapped explosive or harmful gases. Therefore, a roof is not recommended for barrier isolation.

High-Voltage Battery Access

See Battery Discharging Section for procedures to remove the rear seat and turning off the high-voltage service plug.

NOTE: In the event of an emergency, remove the seat cushion with extrication equipments as necessary.

NOTE: Accord Hybrid model shown. Civic Hybrid similar

Battery Discharging

If the high-voltage battery is severely damaged or burned, or the vehicle has been submerged, and water has entered and accumulated on the floor of passenger compartment, the battery must be discharged. Failure to discharge stored or stranded energy remaining in the battery may result in a fire or re-ignition due to damage or short circuit.

See Disable Direct Hazards / Safety Regulations Section for procedures to disconnect the 12-volt battery.

If touching high-voltage cables and/or other high-voltage components is unavoidable, personal protective equipment (insulating gloves, goggles, and boots) should always be worn.

1. Disconnect the 12-volt battery.
2. Remove the rear seat cushion bolts (A).
3. While pushing down on the rear seat cushion, pull the seat hook handles (B) to release the hooks (C). Disconnect the rear seat heater connectors (if equipped).
   

5. Remove the rear seat cushion.
   
6. Remove the service plug cover 10 mm bolts, then remove the service plug cover.
   
7. Push and slide the tab on the service plug until you hear a click.
   

12. Continue filling the pool to a minimum depth of 1.71 ft (522 mm) until the high voltage battery is completely submerged.
    

13. Maintain this water level for at least 3.5 days. If the water level drops below the minimum specified level, add fresh water.

Since the water used for discharging the battery is converted to an aqueous solution containing metals such as Phosphorus (P) and Lithium (Li), dispose of it properly as an industrial waste according to local regulations.

Important Additional Information

Lithium-Ion Battery Fumes or Fire
A damaged high-voltage lithium-ion battery can emit toxic fumes, and the organic solvent used as electrolyte is flammable and corrosive. Responders should wear appropriate personal protective equipment. Even after a lithium-ion battery fire appears to have been extinguished, a renewed or delayed fire can occur. The battery manufacturer cautions responders that extinguishing a lithium-ion battery fire will take a large and sustained volume of water.

In order to minimize the possibility of collateral fire damage, responders should always ensure that a Civic Hybrid with a damaged battery is kept outdoors and far away from other flammable objects.

Lithium-Ion Battery Fluid
Avoid contact with the high-voltage battery fluid. The high-voltage battery contains a flammable electrolyte that could leak as a result of a severe crash. Avoid any skin or eye contact with the electrolyte as it is corrosive. If you accidentally touch it, flush your eyes or skin with a large quantity of water for at least 5 minutes and seek medical attention immediately.

Electric Shock
Unprotected contact with any electrically charged high-voltage component can cause serious injury or death. Receiving an electric shock from a Civic Hybrid, however, is highly unlikely because of the following:

• Contact with the battery module or other high-voltage components can only occur if they are damaged and the contents are exposed, or if they are accessed without following proper precautions.
• Contact with the electric motor can only occur after one or more components are removed.
• The high-voltage cables can be easily identified by their distinctive orange color, and contact with them can be avoided.

If severe damage causes high-voltage components to become exposed, responders should take appropriate precautions and wear appropriate insulated personal protective equipment.

Disposal
The lithium-ion battery, the high-voltage battery fluid, and the water used to discharge the battery must be properly disposed of as industrial waste according to local regulations.

Seat Belts and Airbags

The Civic Hybrid is equipped with lap/shoulder belts in all seating positions. The front seat belts are equipped with pyrotechnically activated tensioners that help tighten the seat belt in a sufficient crash. In addition, the Civic Hybrid is equipped with the following airbags:

• Front Airbags – Driver/Front Passenger
• Knee Airbags – Driver/Front Passenger
• Side Airbags – Front/Rear
• Side Curtain Airbags – Driver's Side/Passenger's Side

It takes up to 3 minutes for the airbags and tensioners to power off after the 12-volt system has been turned off by following the emergency shutdown procedures described in this guide.

In a collision severe enough to deploy one or more of the airbags, the Civic Hybrid electrical system is designed to automatically open the high-voltage electrical contactors. This disconnects the high-voltage battery from the other highvoltage components and stops the flow of electricity in the high-voltage cables.

However, responders should always assume that the highvoltage system is powered on and take the appropriate action described in this guide to power off the system.

Vehicle Collisions

In the event of a crash, the supplemental restraint system (SRS) unit makes a judgment based on input from the impact sensors. If the input values meet various threshold requirements, the SRS unit sends a signal to the high-voltage battery electronic control unit (ECU). The high-voltage battery ECU then turns off the high-voltage battery contactors, stopping the flow of electrical current from the high-voltage battery.

When responding to an incident involving a Civic Hybrid, we recommend that emergency personnel follow their organization's standard operating procedures for assessing and dealing with vehicle emergencies.

Honda recommends that responders follow the procedures in this guide to avoid potentially lethal shock from high voltage.

Dealer Inspection and Repair
A damaged Civic Hybrid should be taken to an authorized Honda dealer for a thorough inspection and repairs. For questions or to locate an authorized Honda dealer, please contact your local Honda dealer or Honda Automobile Customer Service at (800) 999-1009.

High-Voltage Battery Recycling
The high-voltage lithium-ion battery requires special handling and disposal. If disposal is necessary, please contact your local Honda dealer or American Honda's Hybrid Battery Consolidation Center at (800) 555-3497.
