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
your home. Because natural gas

does not contain impurities such as
sulfur, the production of oxides of
sulfur (SOx) and soot pollutants is
eliminated. Using CNG as a fuel also
minimizes the amount of CO2 in the

engine exhaust, producing much
lower emissions than a conventional
gasoline-powered vehicle.

Your Civic GX operates and
performs like a gasoline-powered

Civic. However, there are a few

differences 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 find 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.

MALFUNCTION INDICATOR LAMP

Main Menu

LOW FUEL INDICATOR

Indicator Lights

Malfunction Indicator
Lamp

This indicator comes on for a few

seconds when you turn the ignition
switch ON (II). If it comes on at any
other time, it indicates one of the
engine's emissions control systems
may have a problem. For complete
information, refer to the primary
owner's manual.

This indicator will also come on if

there is a problem in the fuel system.
If this happens, have the vehicle
checked by an authorized dealer as
soon as possible. Drive moderately
until the dealer has inspected the
problem. Avoid full-throttle
acceleration and driving at high
speed.

If you smell natural gas or hear a

hissing sound, the fuel system may

have a leak. Follow the instructions

under If the Fuel System Has a

Leak on page 40 of this supplement.

Instruments and Controls

Low Fuel Indicator

This indicator comes on for a few

seconds when you turn ignition on

(II).

This light comes on as a reminder

that you must refuel soon.

If the outside temperature falls
below 25° F ( — 4° C), the pressure of
the natural gas in the fuel tank may

go down. If this happens, the fuel

gauge will show less than the actual

amount of fuel remaining, and this

indicator may come on.

If this indicator starts blinking and

the fuel level reading goes down to

empty when the engine is running, it

indicates a problem in the fuel

system. Have the vehicle checked by

an authorized Honda Civic GX dealer

as soon as possible.

Gauges

Main Menu

Fuel Gauge

FUEL GAUGE

This gauge shows how much fuel
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 gauge may show slightly more

or less than the actual amount. The

outside temperature and ambient
conditions may affect the pressure
and temperature of the natural gas.

The gauge stays at the same fuel
level reading after you turn off the
ignition. When you add fuel, the
gauge slowly changes to the new
reading after you turn the ignition
switch back ON (II).

Instruments and Controls

Rear Seat

Main Menu

Unlike the standard Civic, only two
people can ride in the rear seat. They
should sit in the outside seating
positions and wear the lap/shoulder

belts. There is no center seat belt.

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

car'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,
the CNG in your car is stored 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 refueling. 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 40.

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.

Before Driving

Fuel, Refueling Procedure

Main Menu

CNG Identification

CNG LABEL

Your vehicle has an identifying

"CNG" label attached next to the
rear license plate. Do not remove
this label. This label is necessary for
insuring your vehicle. Driving
without this label may violate the
laws or regulations in some states.

Before Driving

Refueling Procedure

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 three to five minutes to
fill up the fuel tank.

Slow filling is done with a vehicle
refueling appliance. Refueling takes
approximately 1 hour per gallon.

Always observe all safety
recommendations and operating
instructions on the refueling
equipment.

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 fill pressure
is 3,600 psi (24,800 kPa), so you

should refuel with a P36 nozzle.
Using a P24 or P30 nozzle may cause

the tank to not fill completely.

The natural gas may be warmed by
the refueling process, causing it to
expand 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.

Refueling Procedure

RECEPTACLE DUST CAP

1. Because the fuel receptacle is on
the driver's side of the vehicle,
park with that side closest to the
refueling station.

2. Turn the ignition switch to LOCK
(0) and apply the parking brake.

3. Open the fuel receptacle door by

pushing on the handle to the left
of the driver's seat.

4. Remove the receptacle dust cap
from the fuel receptacle. Clean up
any dirt and debris around the fuel
receptacle.

6. Follow the instructions on the
refueling station to begin refueling.

While refueling, you may hear a

chattering sound. This is normal.

If you hear fuel leaking from the
nozzle-receptacle connection, stop
refueling immediately. Dirt or

other debris may be preventing a
positive connection. Turn off the
refueling station, remove the
nozzle, reconnect it to the
receptacle, and begin refueling
again. If it continues to leak, have
an authorized Honda Civic GX

dealer inspect the sealing O-ring
the receptacle for damage and
wear.

7. Refueling will stop automatically
when the tank is full. Follow the
instructions on the refueling

station to turn it off.

8. Disconnect the CNG fill nozzle
from the fuel receptacle by

turning the lever on the

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
gasoline-powered vehicle.

Improper parts or components can
damage your vehicle's fuel system
and affect your vehicle's safety and
performance.

Fuel System Components, Fuel Cut-off System

Main Menu

Fuel system maintenance and repair

should be done only by an authorized
Honda Civic GX dealer.

Fuel Cut-off System

The in-tank fuel shut-off 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 Shut-off Valve

MANUAL SHUT-OFF VALVE

A manual shut-off 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.

Before Driving

Fuel Cut-off System, Carrying Cargo

Main Menu

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.

Before Driving

Carrying Cargo

The maximum load you can carry in

your car is 635 Ibs (288 kg). That

figure includes the total weight of

four occupants (driver and three

passengers), their cargo, and any

accessories. The maximum
recommended weight for cargo in
the trunk is 35 Ibs (16 kg).

The fuel tank is located in the trunk,
with a partition between the fuel
tank and the cargo space.

When you store small items in the
trunk, secure them so they will not

shift while you are driving. Loose
items can fly over the partition and

damage the fuel tank and fuel

system components.

Do not carry large, heavy or pointed
objects in the trunk. They may
damage the fuel tank.

Starting the Engine

Main Menu

1. Apply the parking brake.

2. In cold weather, turn off all
electrical accessories to reduce
the drain on the battery.

3. Make sure the shift lever is in
Park. Press on the brake pedal.

4. Without touching the accelerator
pedal, turn the ignition key to the
ON (II) position. You may hear a
click from the in-tank fuel shut-off

valve.

Make sure the Malfunction
Indicator Lamp goes out before
you turn the ignition key to the
START (III) position.

5. Turn the ignition key to START
(III). If the engine does not start

right away, do not hold the key in
START (III) for more than 15
seconds at a time. Pause for at
least 10 seconds before trying
again.

6. If the engine does not start within
15 seconds, or starts but stalls

right away, repeat step 5 with the
accelerator pedal pressed half-way
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.

7. If the engine still does not start,

press the accelerator pedal all the
way down and hold it there while
starting. As before, keep the
ignition key in the START (III)
position for no more than 15
seconds. Return to step 6 if the
engine does not start. If it starts,
lift your foot off the accelerator
pedal so the engine does not race.

If the outside temperature is below

— 4°F ( — 20°C), the engine may be
harder to start. In this case, use the
starting procedure for cold weather
at high altitude described in the next
column.

Starting in Cold Weather at High

Altitude (Above 5,000 feet/

1,600 meters)

An engine is harder to start in cold

weather. The thinner air found at
high altitude above 5,000 feet (1,600
meters) adds to the problem.
Use the following procedure:

1. Turn off all electrical accessories
to reduce the drain on the battery.

2. Make sure the Malfunction
Indicator Lamp goes out before
you turn the ignition key to the
START (III) position.
