Note: Block the wheels if the 12-volt battery power is NOT available. The parking brake cannot be applied or released if the 12-volt battery is not available.

To Apply

The electric parking brake can be applied any time the vehicle has battery, no matter which position the power mode is in.

1. Pull the electric parking brake switch up gently and securely.

The indicator in the switch comes on.

The parking brake and brake system indicator (red) comes on.

To Release

The power mode must be in ON in order to release the electric parking brake.

1. Depress the brake pedal.

2. Press the electric parking brake switch.

The indicator in the switch goes off.

The parking brake and brake system indicator (red) goes off.

1. Press the POWER button twice to turn the vehicle ON. NOTE: This action will not turn the engine/hybrid system on.

2. Press and hold the brake pedal, press the release button, then shift to the P position on the Gear Selector to shift the transmission to Park, or N to shift the transmission to Neutral.

NOTE: The gear selector can be shifted into the P or N position without the POWER on or pressing the brake pedal if the 12-volt system is not available.

The preferred method for high-voltage shutdown is to push and hold the POWER button for 3 seconds.

This simple action turns the vehicle OFF and immediately shuts down the high-voltage 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.

The alternative best method is to locate and cut the negative 12-volt battery cable and the Power Control Unit (PCU) cable in the engine compartment. Cutting both cables immediately turns off and shuts down the high-voltage system controllers and engine.

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

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

4. Locate the two cut point labels as shown in the guide, 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.

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.

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

• If you need to cut the hood to open it, be sure to stay within the cut zone shown around the vehicle’s front emblem area.

• 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 shown, which generally encompasses the area below the windows, between the front and rear wheel wells. Avoid cutting near the Side Curtain Airbag Inflator, located along the roofline.

Power Seats Adjustment (Driver’s seat)

• Horizontal Position Adjustment: Use the horizontal control.

• Height Adjustment: Use the vertical control.

• Seat-back Angle Adjustment: Use the recline control.

Manual Seats Adjustment

• Height Adjustment (Driver’s side only): Pull up or push down the lever to raise or lower the seat.

• Horizontal Position Adjustment: Pull up on the bar under the front of the seat to move it, then release the bar.

• Seat-back Angle Adjustment: Pull up the lever on the side of the seat to change the angle.

Head Rest Adjustment

• To raise the head restraint: Pull it upward.

• To lower the head restraint: Push down while pressing the release button.

Steering Column Adjustment

1. Pull the steering wheel adjustment lever down. The lever is under the steering column.

2. Move the steering wheel up or down, and in or out.

3. Push the steering wheel adjustment lever up to lock the steering wheel in position.

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

1. Extinguish the fire using a large volume of water such as from a fire hydrant, well water, or pond water. If water is not available, an ABC powder fire extinguisher may be used as an alternative.

2. If it is safe to do so, open the passenger’s side rear door and direct water from the right side into the high-voltage battery vent under the rear seat cushion.

3. Continue extinguishing until a complete suppression of fire and smoke is observed from the battery area.

4. Once signs of active fire have completely subsided (e.g. no visible smoking), a thermal camera should be used to evaluate and monitor the temperature of the battery unit.

NOTE: The battery temperature should continue to be monitored. If the battery temperature begins to increase, a possibility for reignition exists, and additional water or a fire extinguisher should be used to mitigate reignition.

WARNING:

– Do NOT attempt to open the battery cover at this time.

– Never use seawater or any water containing salt.

– Always assume the high voltage battery contains stranded energy and a possibility for reignition exists.

If a Civic Hybrid is submerged or partly submerged in water, first pull the vehicle out of the water, then shut down the high-voltage system using the high-voltage shutdown procedures.

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.

Aside from severe damage to the vehicle, there is no risk of an electric shock from touching the vehicle’s body or framework – in or out of the water. If the high-voltage battery was submerged, you may hear noises from the battery as the cells are being discharged from shorting.

See Section 8 (Towing/Transportation/Storage) for additional procedures including discharging the high voltage battery.

1. Set the parking brake.

2. Turn the vehicle to the OFF mode.

3. Remove the built-in key from the keyless remote.

4. Wrap a cloth around the tip of the built-in key. Put it into the shift lock release slot and remove the cover. A pocket screwdriver can also be used.

5. Insert the key into the shift lock release slot.

6. While pushing the key in, press the shift lever release button, and place the shift lever into N. The lock is now released.

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: Secure the vehicle on the flat-bed tow truck and apply the parking brake.

• Front Wheel Type: Lift the front wheels and 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.

WARNING: 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. 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 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 Points:

Use the indicated lifting points to raise the vehicle.

• Recommended Lifting Points (for a vehicle lift): There are four points, located on the reinforced frame just behind the front wheels and just in front of the rear wheels.

• Floor Jack Lifting Points: There are front and rear central jacking points, as well as side jacking points near the wheels.

• Front Lifting Point (If Necessary): A front tow hook can be used for lifting if needed.

Securing the Vehicle (Tie-Downs):

The recommended tie-down locations for securing the vehicle are four tie-down slots covered by rubber plugs. There are two behind the front wheels and two in front of the rear wheels.

4-Door Model

5-Door Model

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.

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 the passenger compartment, the battery must be discharged. Failure to discharge stored energy may result in a fire or re-ignition.

If touching 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).

4. Remove the rear seat cushion.

5. Remove the service plug cover 10 mm bolts, then remove the service plug cover.

6. Push and slide the tab on the service plug until you hear a click.

7. Raise the lever and remove the service plug.

8. Set up a pool approximately 18 feet long x 9 feet wide x 3 feet high in a well-ventilated outdoor area.

9. Use a forklift or similar equipment to place the vehicle in the center of the pool.

10. Fill the pool with water from a fire hydrant, well water, or pond water until the high voltage battery is completely submerged. If there is a risk of water leakage from the pool, place a thick plastic sheet under the pool. Never use seawater or any water containing salt.

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

12. 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.

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. Extinguishing a lithium-ion battery fire will take a large and sustained volume of water. To minimize 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 battery contains a flammable electrolyte that could leak. 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 is highly unlikely because:

• 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.

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.

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.

The Civic Hybrid is also 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 high-voltage components and stops the flow of electricity in the high-voltage cables.

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

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.
