Introduction
Your vehicle runs on compressed natural gas (CNG), a highly
pressurized version of the same clean-burning natural gas used in
many homes and businesses.
Your vehicle operates and performs like a gasoline-powered
vehicle. However, there are a few differences you should be aware
of. In addition to reading your vehicle’s owner’s manual, please
read this supplement carefully to understand the operation and
unique features of your vehicle.
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.
CNG (Compressed Natural Gas),
Your Vehicle’s Fuel
The main component of CNG (Compressed Natural Gas) is
methane. It is a highly flammable colorless gas that is used in
home appliances such as kitchen stoves and water heaters.
The CNG in your vehicle is stored under high pressure. The system
is designed to hold gas at the maximum of 3,600 psi/24,800 kPa,
and 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, shut down the CNG system immediately.
If a Fuel Leak is Detected
P.33
Safety Standards of the Fuel Tank
Your vehicle’s fuel tank meets the safety standards of NGV-2/
NFPA-52/DOT NHTSA FMVSS 304.

Home
Fuel Quality and Home Refueling
In order to insure that your Civic Natural Gas vehicle receives
CNG fuel with quality equal to or above the NFPA-52 and SAE
J1616 fuel standards, Honda only recommends that your vehicle
be refueled at a public commercial-grade CNG refueling station.
Public stations offer an approximately five minute refueling time,
and the assurance of natural gas quality meeting NFPA and SAE
standards.
Public refueling stations use commercial quality filtering and
drying equipment that helps to assure your vehicle will only be
refueled with automotive grade CNG, meeting the NFPA and
SAE standards. Due to the nature of home natural gas supplies
from gas companies, even with filtering and drying equipment,
it is possible to introduce moisture into your vehicle’s CNG tank
and fueling system, possibly resulting in damage to the system.
Moisture damage can require inconvenient and costly repairs.
Due to the wide variation of natural gas quality for home use,
Honda does not recommend the use of home refueling at this
time. If you choose to use a home refueling device, you should
consult with the equipment manufacturer and the local natural
gas contractor that installs the equipment. Ask them to evaluate
the quality of the natural gas at the location the refueling
equipment will be installed. They may recommend additional
filtering and drying equipment, and a schedule for maintaining
this equipment to insure delivery of natural gas that meets
the NFPA and SAE standards of fuel quality. It is important to
understand the quality of fuel not just when it is evaluated, but
the range of quality, particularly moisture content, from the
natural gas provider.
The choice to use a slow fill or home refueling equipment,
evaluation of the suitability of using this equipment, installation
and proper maintenance of the equipment, and any damage
associated with the use of this equipment, is the sole responsibility
of you, the owner.
If your vehicle needs repairs, is examined by an authorized
Honda Civic Natural Gas automobile dealer, and is found to have
contamination in the fuel system or damage to the fuel system as
a result of using sub standard natural gas, your warranty claim for
repairs may be denied.

Storing Cargo in the Trunk
Do not put large, heavy or pointed objects in the trunk. When storing items,
properly secure them so that they do not move around while driving. The fuel
tank is located in the trunk, and although a partition separates the tank from the
cargo space, large items or loose items can damage the fuel tank and fuel system
components.

Starting the Engine
Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and
in thinner air found at altitudes above 8,000 feet
(2,400 meters).
When starting the engine in cold weather, turn
off all electrical accessories (the lights, heating
and cooling system, and rear defogger) in order to
reduce battery drain.
If you live in a region where winter is extremely
cold, an engine block heater will improve starting
and warming of the engine. If temperatures
consistently below -22°F (-30°C) are expected, the
coolant mixture should be changed to a higher
concentration to prevent freezing. Consult a dealer
for details.
If the exhaust system sounds abnormal or you
can smell exhaust gas inside the vehicle, have
your vehicle checked by a dealer. There may be a
problem with the engine or exhaust system.

Fuel Information
Only fuels that can be used
NFPA-52 and SAE J1616 standards
Use of a fuel that does not meet these standards can cause a decrease in engine
power and damage the emission controls.
Fuel tank capacity:
Slow filling
6.96 gasoline gallon equivalent (3,000 psi)
7.77 gasoline gallon equivalent (3,600 psi)
Fast filling
5.84 gasoline gallon equivalent (3,000 psi)
6.51 gasoline gallon equivalent (3,600 psi)
How to Refuel
There are two methods of refueling:
Fast filling
It takes about three to five minutes to fill up the fuel tank. This method is usually
available at stations designed to refuel natural gas vehicles.
During fast filling, the natural gas is warmed, causing the pressure in the tank to
rise and reduces the amount of fuel you can put in.
Slow filling
It takes about an hour and a half per GGE (Gasoline Gallon Equivalent) to fill up
the fuel tank. This method can be done using a vehicle refueling appliance.

How to Refuel
WARNING
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 Natural Gas
dealer.
NOTICE
Using fast fill equipment at temperature below -4°F
(-20°C) may damage the fuel system, potentially
causing a leak.

Refueling Procedure Example
How to Refuel
Always observe all safety recommendations and
operating instructions on the refueling equipment.
Use a fuel filler nozzle that complies with ANSI/AGA
NGV-1-2008 standards.
The CNG filler nozzle mechanism may vary by
service station. Each nozzle standard has different
maximum pressure:
P24
•
－
2,400 psi (16,500 kPa)
P30
•
－
3,000 psi (20,700 kPa)
P36
•
－
3,600 psi (24,800 kPa)
The refueling steps shown in this manual are the
typical fast fill refueling procedure. You may need
to go through different steps at a station with slow
fill equipment or other types of equipment. Always
follow the instructions provided on site.
1. Stop your vehicle with the service station
pump on the left side of the vehicle in the
rear.
2. Turn off the engine.
3. Push on the fuel receptacle lid release
handle at the foot of the driver’s seat.
The fuel receptacle lid opens.
4. Remove the receptacle dust cap from the
fuel receptacle.
Clean off any dirt or debris around the
fuel receptacle.

How to Refuel
If you hear or see fuel/vapor leaking from the
nozzle-receptacle connection, stop refueling
immediately. Turn off the refueling station, remove
the nozzle, reconnect it to the receptacle, and begin
refueling again. Dirt or debris adhered to the inside
of the fuel receptacle can cause a gas leak. Remove
dirt or debris from the CNG filler nozzle with a
clean, dry rag.
If it continues to leak, have an authorized CNG
dealer inspect the sealing O-ring in the fuel
receptacle. It may be missing, damaged, or worn.
If you are not sure how to operate the refueling
station, ask for assistance.
6. Turn the lever until the arrows on the
nozzle point to each other, then follow
the instructions on the refueling station to
begin refueling.
While refueling, you may hear a chattering
sound. This is normal.
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 slowly turning the lever
on the nozzle 180 degrees.
You may hear a brief hissing sound as a
small amount of gas escapes, and may
detect a slight gas odor. This is normal.
9. After filling, replace the receptacle dust
cap on the fuel receptacle securely.
Shut the fuel receptacle lid by hand.

repair kit so that you can drive to the nearest service station for a more permanent
repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on firm, level, and non-slippery surface and apply the parking
brake.
2. Put the shift lever in

WARNING
Running the engine with the vehicle in
an enclosed or even partly enclosed area
can cause a rapid build-up of toxic carbon
monoxide.
Breathing this colorless, odorless gas can
cause unconsciousness and even death.
Only run the engine to power the air
compressor with the vehicle outdoors.
NOTICE
Do not operate the tire repair kit compressor
for more than 15 minutes. The accessory power
socket and compressor can overheat and become
permanently damaged.
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher
than actual. After the sealant injection is complete
the pressure will drop and then begin to rise again
as the tire is inflated with air. This is normal. To
accurately measure the air pressure using the gauge,
turn the air compressor off only after the sealant
injection is complete.
If the required air pressure is not reached within
10 minutes, the tire may be too severely damaged
for the kit to provide the necessary seal and your
vehicle will need to be towed.

Your vehicle’s fuel system includes a fuel tank, a
fuel pressure regulator, a manual shut-off valve,
high pressure fuel lines, and other components that
comply with NFPA-52 standards.
The 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 refueling.
Never modify or replace any original components or
parts with those specified for a gasoline vehicle.
Improper parts or components can damage your
vehicle’s fuel system and affect your vehicle’s safety
performance.
Unlike some gasoline models, your vehicle’s rear
seat-back cannot be folded down.
