CNG (compressed natural gas) vehicles and respond safely to incidents involving these
vehicles.
Part 1 presents general information and recommendations that apply to all Honda CNG
vehicles produced through the 2012 model year. Part 2 contains model-specific information
for each of the four models: the 1998-2000 Civic CNG, the 2001-2005 Civic CNG, the
2006-2011 Civic CNG, and the 2012 Civic CNG. This guide will be updated or replaced as
Honda continues to introduce new CNG vehicles.
We hope this publication provides the kind of information you need. This booklet is available

Type, Size, and Appearance
The Civic GX (Natural Gas) is a four-door,
four-passenger car with a conventional
internal combustion engine fueled by
compressed natural gas (CNG). All four
models are nearly identical in appearance
to their gasoline-powered counterparts
except for labels indentifying them as
powered by CNG.
All 1998-2012 Civic CNG vehicles have a
diamond label on the right rear of the
vehicle that identifies it as being powered by
compressed natural gas.
Along with the distinctive diamond CNG
label, 1998-2011 Civic GX vehicles have a NGV
(Natural Gas Vehicle) label on the lower left
and right rear doors.
The 2012 model has an emblem on the right
rear of the vehicle, just above the diamond
CNG label.

The fuel tank is in the trunk, behind a
removable divider that separates it from the
cargo area. The 36.6-inch-long (927 mm) and
18-inch-diameter (460 mm) tank is securely
mounted between two frames attached to
the trunk floor. The tank is made of flame-
resistant materials and certified to have
passed rigid dropping, bullet-impact, and
crash tests.
The natural gas in the tank is compressed up
to 3,600 psi. Fuel capacity is equivalent to
8 gallons of gasoline.
High-pressure CNG Line
Compressed natural gas (CNG) flows from
the fuel tank to the engine through a
stainless-steel, high-pressure CNG line that is
visible under the driver’s side of the car. The
high-pressure CNG line is certified to an
internal pressure of 10,000 psi.
Engine
In the engine compartment, CNG pressure is
reduced to about 40 psi. At this pressure,
the CNG flows into the engine through the
four fuel injectors.
Battery
A conventional 12-volt battery is located
under the hood. This battery powers the
lights, audio system, airbags, seat-belt
tensioners, and other standard electronics. It
also powers a solenoid valve inside the fuel
tank (see page 4).
High-pressure CNG Line

Vehicle Description
Occupant Protection Features
All Civic GX's have lap/shoulder belts and
dual front airbags. The 2001 and later
models add pyrotechnic seat belt tensioners
and side airbags for the driver and front
passenger. The 2006 and later models add
side-curtain airbags. To disable the airbags
and tensioners, the ignition switch must be
in the LOCK (0) position for at least 3
minutes, or the engine must be stopped and
the 12 volt battery must be disconnected for
at least 3 minutes.
CNG Safety Features
The fuel tank has an internal solenoid valve
that automatically shuts off the flow of CNG
whenever the ignition switch is in the LOCK
(0) or ACCESSORY (I) position, or when one
of several sensors in the fuel system detects
a significant fuel leak.
The fuel tank also has an internal pressure
relief device to release all CNG if the
temperature in the tank exceeds 216ºF
(102ºC). When this device is activated, the
CNG is routed out of the car through a
pressure relief outlet under the left rear
corner of the vehicle.

CNG Manual Shutoff Valve
The Civic GX has a CNG manual shutoff valve
to stop the flow of CNG from the fuel tank.
The red handle of the valve is located near
the left rear tire and the splash guard on
1998-2005 models and in front of the left
rear tire on 2006 and later models.
To access the handle, reach around the front
or rear of the left rear wheel, depending on
the model. To stop the flow of CNG, turn

The Civic GX (Natural Gas) does not present
any greater hazards than a conventional
gasoline powered vehicle. Each of the four
models have performed very well in crash
tests performed according to the National
Highway Traffic Safety Administration
standards. As a fuel, CNG also has a long
record of safe use in private, corporate, and
government vehicles.
Compressed Natural Gas
The CNG used in the Civic GX is a nontoxic
gas that cannot spill and cannot
contaminate the ground water.
Like other fuels, however, CNG is both
flammable and explosive. As illustrated in
the graph, when mixed with air, CNG has
much higher flammability and explosivity
limits than gasoline. Its ignition temperature
is also very high (1,200ºF), twice as high as
gasoline.
To reduce the chance of CNG leakage, the
Civic GX has many built-in safety features to
help contain the fuel, detect a leak, and
automatically shut off fuel flow if a leak is
detected (see pages 4-5). As with the natural
gas used in homes and industry, an odor is
added to the CNG that helps you detect a
leak before it can become a problem.
Since CNG is much lighter than air, a leak
occurring in an open area would quickly rise
and dissipate into the atmosphere. In an
enclosed space, CNG would collect in the
uppermost areas.

Potential Hazards
Part 1
Based on discussions with rescue
professionals, we recommend that
emergency response personnel follow
standard procedures developed by their own
organization for assessing situations and
dealing with potential hazards. Given our
knowledge of the Civic GX, we also
recommend the procedures outlined in this
section.
Incidents Involving Fire
If a Civic GX is involved in a fire, follow
standard fire-fighting procedures, but keep
away from the rear of the car until the fire
is completely out. Remember that high
temperatures can cause all CNG in the fuel
tank to be released through the pressure
relief outlet at the left rear of the car (see
page 4).
Damaged Vehicle
Before attempting to rescue occupants from
a damaged Civic GX, or before moving it,
you must stop the flow of CNG and turn off
the engine.
You have three ways to do this, ranging
from the best method to the least desirable
which are detailed on the following pages.
Part 1
Emergency Procedures
Best Method for Stopping CNG Flow
and Turning Off the Engine
Turn off the ignition switch, and remove
the key.
Turning off the ignition switch automatically
shuts off the flow of CNG from the fuel
tank. It also turns off power to the airbags
and the seat belt tensioners within 3
minutes.
To use this method, turn the ignition switch
to the LOCK (0) position, and remove the
key. (Removing the key prevents the vehicle
from being inadvertently restarted.)
Second-Best Method for Stopping
CNG Flow and Turning Off the
Engine
Remove the main fuse, and disconnect
This method should be used if the ignition
switch is in the ON (II) position, and you
cannot reach the key, but you can reach
under the hood.
Removing the main fuse shuts off the flow
of CNG from the fuel tank and turns off the
engine. Disconnecting the battery negative
cable cuts power to the airbags and the seat
belt tensioners within 3 minutes. It also
prevents the engine from being restarted.
Emergency Procedures

or cut the battery negative cable.
To use this method, do this:
1.
Open the hood and locate the under-
hood fuse box and the battery.
2.
Remove the fuse box cover, and locate
the main fuse.
3.
Remove the screws from the main fuse
with a Phillips screwdriver, then remove
the main fuse.
4.
Disconnect or cut the negative battery
cable.

Emergency Procedures
Least-Desirable Method for Stopping
CNG Flow and Turning Off the
Engine
Turn off the CNG manual shutoff valve.
This method does not disable the airbags or
the seat belt tensioners. It should be used
only if the engine is running, you cannot
reach the key, and you cannot reach under
the hood.
Turning off the CNG manual shutoff valve
immediately stops the flow of CNG from the
fuel tank. The engine will stop within 1
minute of turning off the valve.
To use this method, do this:
1.
Locate the red handle of the CNG
manual shutoff valve. Depending on the
model, it is either in front of or behind
the left rear tire. See page 5.
2.
Turn the handle one-quarter turn
clockwise to stop the flow of CNG.

Emergency Procedures
Part 1
If you need to break windows, cut into the
body, or use “Jaws of Life”-type equipment
to remove occupants from a damaged car,
be sure to stay within the cut zone as
indicated in Part 2.
If you need to move the Civic GX only a
short distance, such as to the side of the
road, and it can still roll on the ground, the
easiest way is to shift the transmission to
neutral, then push the car manually.
Example: Cut Zone
The preferred method for transporting the
Civic GX away from an emergency location is
on a flatbed truck.
If a flatbed is not available, wheel-lift
equipment may be used, preferably with the
front wheels lifted. If the rear wheels must
be raised, set the parking brake, and shift
the transmission to neutral before towing.
