Introduction
Main Menu
Your Civic GX runs on Compressed
Natural Gas (CNG), a highly
pressurized version of the same
clean-burning natural gas used in
many homes.
Your Civic GX operates and
performs like a gasoline-powered
Civic. However, there are a few
diff erences you should be aware of .
In addition to reading the Civic
Sedan owner’s manual, please read
this supplement carefully to
understand the operation and unique
features of your Civic GX.

You will f ind important safety
information in this supplement and
in the owner’s manual. This
information alerts you to potential
hazards that could hurt you or others.
Please read it carefully.

may have a problem. For complete
information, refer to the Civic Sedan
owner’s manual.
This indicator will also come on if
there is a problem in the fuel system.
If this happens, have the vehicle
checkedbyanauthorizedHonda

Gauges
Main Menu
Fuel Gauge
UPPER ‘‘F’’ MARK
LOWER ‘‘F’’ MARK
FUEL GAUGE
This gauge shows how much f uel
you have. The quantity of fuel
remaining in the tank is calculated
based on the pressure and
temperature of the natural gas in the
fuel tank.
The lower ‘‘F’’ mark indicates a full
tank at a fill pressure of 3,000 psi.
The upper ‘‘F’’ mark indicates a full
tank at a fill pressure of 3,600 psi.
The gauge may show slightly more
or less than the actual amount. The
outside temperature, fill method, and
ambient conditions may affect the
pressure and temperature of the
natural gas.

Instruments and Controls
Fuel
Main Menu
Your Civic GX is designed to operate
on Compressed Natural Gas (CNG).
The natural gas you use to refuel
must meet NFPA-52 and SAE J1616
standards for fuel composition and
quality.
If you use a fuel that does not meet
these standards, you may feel a
decrease in engine power and your
vehicle’s emissions controls may be
damaged.
Compressed Natural Gas (CNG)
The main component of compressed
natural gas is methane, a highly
flammable, colorless gas. While it is
the same gas that is burned in
everyday home appliances such as
kitchen stoves and water heaters,
theCNGinyourvehicleisstored
under high pressure (maximum
3,600 psi/24,800 kPa).
The CNG fuel system in your Civic,
including the tank and hose, has
been designed to hold gas at this
pressure. It has also been tested for
safety. You should never smell gas
or hear a hissing sound unless you
are ref ueling. If you smell gas or
hear a hissing sound at any other
time, you need to shut down the fuel
system. Follow the instructions on
page .
13
Compressed natural gas is
flammable and highly explosive.
You could be killed or seriously
injured if leaking natural gas is
ignited.
If you suspect a leak, have your
vehicle immediately inspected
and repaired by an authorized
Honda Civic GX dealer.

Fuel, Refueling Procedure
Main Menu
CNG Identif ication Ref ueling Procedure
CNG LABEL
There are two methods of refueling,
fast filling or slow filling.
Fast filling is normally used in fuel
stations for natural gas vehicles. It
takes about 3 to 5 minutes to fill up
the fuel tank.
Slow filling is done with a vehicle
refueling appliance. Ref ueling takes
about 1 hour per gasoline gallon
equivalent.
Your vehicle has an identifying
‘‘CNG’’ label attached next to the
rear license plate. Do not remove
this label. This label is necessary for
Always observe all safety
recommendations and operating
instructions on the refueling
equipment. During a fast fill, the natural gas will

without this label may violate the
laws or regulations in some states.

Before Driving
When refueling, you should use a
fuel fill nozzle that complies with
ANSI/AGA NGV-1-1994 standards.
Nozzles are designed according to
their maximum fill pressure: P24 for
2,400 psi (pounds per square inch),
P30 for 3,000 psi, and P36 for 3,600
psi.
Your Civic’s maximum f ill pressure
is 3,600 psi (24,800 kPa), so you
should refuel with a P36 nozzle.
Using a P30 nozzle will fill the tank
to the second (3,000 psi) fill mark on
the fuel gauge. Using a P24 nozzle
will not fill the tank completely.
be warmed by the refueling process,
causing the pressure in the tank to
rise and reduce the amount of fuel
you can put in.
Filling the Fuel Tank
Main Menu
The refueling procedure can vary
with the refueling station. The
following explains the typical
refueling procedure with fast fill
equipment. With slow fill equipment,
or other types of refueling
equipment, follow the instructions on
the equipment.

Fuel system components include a
fuel tank located in the trunk, an
integrated fuel pressure regulator,
an in-tank fuel shutoff valve, high
pressure f uel lines, electronically
controlled multipoint fuel injectors,
and other equipment.
Fuel system components in the Civic
CNG comply with NFPA-52
standards.
Your vehicle is equipped with
genuine Honda component parts that
have been designed and approved
for use in a compressed natural gas
vehicle. Never modify or replace any
original components or parts with
those specified for a gasolinepowered vehicle.
Improper parts or components can
damage your vehicle’s fuel system
and affect your vehicle’s safety and
performance.
Fuel System Components, Fuel Cutoff System
Main Menu
Fuel system maintenance and repair
should be done only by an authorized
Honda Civic GX dealer.
Tampering with, or improperly
maintaining the high-pressure
fuel system can cause a
dangerous condition in which
you can be seriously hurt or
killed.
Never attempt to modify the fuel
system, and always have fuel
system maintenance performed
by an authorized Honda Civic
GX dealer, or a qualified NGV
technician.
Fuel Cutoff System
The in-tank fuel shutoff valve is
controlled by the ignition switch.
When the ignition switch is in the
LOCK (0) or ACCESSORY (I)
position, the valve is closed, shutting
off fuel flow to the engine. It opens
when the ignition switch is turned to
ON (II). This is similar to how an
electric fuel pump works in a
gasoline-powered vehicle.
Manual Shutoff Valve
MANUAL SHUTOFF VALVE
A manual shutoff valve is located
underneath the vehicle, near the rear
tire on the driver’s side. We
recommend that you locate this
valve so you can find it quickly.
To turn off the valve, turn the lever
one-quarter turn clockwise. Turn it
counterclockwise to turn the valve
back on.
Turn off the valve if you ever suspect
a fuel leak or are involved in an
accident.
