Natural Gas (CNG) models
Fuel Information
Compressed natural gas that meets NFPA-52 and SAE J1616 standards is
required.
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)
Your vehicle runs on compressed natural gas (CNG). The CNG in your vehi\
cle is
stored under high pressure. The system is designed to hold gas at the ma\
ximum
of 3,600 psi/24,800 kPa, and you should never smell gas or hear a hissin\
g sound
unless you are refueling. If you smell gas or hear a hissing sound at an\
y other
time, shut down the CNG system immediately.
Your vehicle’s fuel tank meets the safety standards of NGV-2/NFPA-52/DOT NHTSA
FMVSS 304.
To ensure that your Civic Natural Gas vehicle receives CNG fuel with qual\
ity 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 fi ve minute refueling time, and the
assurance of natural gas quality meeting NFPA and SAE standards.
For information on the locations of the CNG fuel stations, visit either \
www.afdc.
energy.gov/afdc/fuels/natural_gas_locations.html or www.cngprices.com, or call
NGVAmerica at (202) 824-7360. In California, visit www.cngvc.org.
The location of the CNG pump can vary from station to station, may not b\
e clearly
marked, or be readily accessible during certain hours. It is recommended\
that you
call the station (the number should be displayed with the address infor\
mation) to
verify the location and availability of the CNG pump before you arrive.
Have an authorized dealer or certifi ed NGV technician inspect the fuel tank every
three years, or 36,000 miles, whichever comes fi rst, and replace it 15 years from
its production date. Do not use an expired tank or reuse the old tank fo\
r other
purposes. After a collision, have the fuel tank inspected by an authoriz\
ed dealer or
certifi ed NGV technician.
Compressed natural gas is highly fl ammable and explosive. You can be burned
or seriously injured if leaking natural gas is ignited.
If you suspect a leak, have your vehicle immediately inspected and repai\
red by
an authorized Honda Civic Natural Gas dealer.
WARNING
Using fast fi ll equipment at temperature below -4°F (-20°C) may damage the fu\
el
system, potentially causing a leak.
NOTICE
How to RefuelSlow filling
It takes about an hour and a half per GGE (Gasoline Gallon Equivalent)\
to fi ll up the
fuel tank. This method can be done using a vehicle refueling appliance.
Fast filling
It takes about 3–5 minutes to fi ll up the fuel tank. This method is usually available
at stations designed to refuel natural gas vehicles. During fast fi lling, the natural
gas is warmed, causing the pressure in the tank to rise and reduces the \
amount of
fuel you can put in. The steps for fast fi lling are described below.
1. The fuel fi ll door is located at the left rear of the vehicle. Park next to the service pump that is most
accessible.
2. Turn off the engine.
3. Push the fuel fi ll door release handle near the bottom of the driver’s seat. The fuel fi ll door opens.
4. Remove the receptacle dust cap from the fuel receptacle.
5. Securely connect the CNG fi ll nozzle to the fuel receptacle.
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. You may hear
a chattering sound; this is normal. If you hear or
see fuel/vapor leaking from the nozzle-receptacle
connection, stop refueling immediately.
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 fi ll 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 fi lling, replace the receptacle dust cap on the fuel receptacle securely. Close the fuel lid door.
