Introduction
2008 Civic Sedan GX
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.

Fuel
2008 Civic Sedan GX
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.
6
Before Driving
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 system in your vehicle,
including the tank and hoses, 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
CNG system. Follow the instructions
on page .12
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
2008 Civic Sedan GX
Main Menu
CNG Identification Ref ueling Procedure
CNG LABEL
There are two methods of refueling,
fast filling or slow f illing.
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. Refueling 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.
insuring your vehicle. Driving
without this label may violate the
laws or regulations in some states.
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 vehicle’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.
During a fast fill, the natural gas is
warmed by the refueling process.
This causes the pressure in the tank
to rise and reduces the amount of
fuel you can put in.
The label shown below is attached to
the fuel receptacle lid.

Using f ast f ill equipment at
temperatures below 4°F ( 16°C) may
−
damage the f uel system, potentially
causing a leak. Only use slow fill
equipment when ambient temperatures
are below 4°F ( 16°C).

Filling the Fuel Tank
The refueling equipment and
procedure can vary with the
refueling station. The CNG fill
nozzle may not look or work like the
example on the next page. The
following steps explain the typical
refueling procedure with fast fill
equipment. With slow fill equipment,
or other types of refueling
equipment, follow the instructions on
the equipment.

Before Driving
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
the ON (II) position. This is similar
to how an electric fuel pump works
in a gasoline-powered vehicle.
Manual Shutoff Valve

example, if the ‘‘XXX’’ amount
equals 1,400 lbs. and there will be
five 150 lb. passengers in your
vehicle, the amount of available
cargo and luggage load capacity is
650 lbs.
(1,400 750 (5 150) = 650 lbs.)

Determine the combined weight
(5)
of luggage and cargo being loaded
on the vehicle. That weight may
not safely exceed the available
cargo and luggage load capacity
calculated in Step 4.
If your vehicle will be towing a

Starting the Engine, Towing a Trailer
2008 Civic Sedan GX
Main Menu
If you regularly drive your vehicle in
very cold weather [below 4°F
( 20°C)], consider having an
−
engine block heater installed. It
should greatly improve starting in
very cold weather.
Also, when driving in very cold
weather, make sure that the 12 V
battery is fully charged either by
driving several miles each day or by
using a 12 V charger to fully charge
the battery.
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 f ound at
high altitude above 5,000 feet (1,600
meters) adds to the problem.
The unique design of a CNG engine
makes it even more dif ficult or
impossible to start if temperatures
drop below 4°F ( 16°C).

have your vehicle towed to an
authorized Honda Civic GX dealer
