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.25
Safety Standards of the Fuel Tank
Your vehicle’s fuel tank meets the safety standards of NGV-2/
NFPA-52/DOT NHTSA FMVSS 304.

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.

When the outside air gets very cold
[below 25°F (

of the natural gas inside the tank
goes down, and the fuel gauge may
indicate that you have less fuel than
what actually remains in the tank.
Keep this in mind if the low fuel

Fuel Gauge Fuel Gauge
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, average fuel, range, and instant fuel
economy show more or less than the actual
amount. The tank temperature, fill method, and
ambient conditions may affect the pressure and
temperature of the natural gas.
You can choose whether to reset trip A and average
fuel economy A when you refuel, using the multi-
information display.
Refueling a small amount of gas may not trigger trip
A and the average fuel economy to reset.
FUEL LID OPEN
Displays the amount of fuel left 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.
If the fuel receptacle lid is open, the fuel gauge blinks when you turn the ignition

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.
Towing a Trailer
Your vehicle is not designed to tow a trailer. Attempting to do so can void your
warranties.
