Low Fuel
Indicator• Comes on when you turn the
ignition switch to ON
II, and
goes off when the engine starts.
• Comes on when the fuel reserve is running low.
• Blinks if there is a problem with the fuel gauge. •
Comes on - Refuel your vehicle as
soon as possible.
When the outside air gets very cold
[below 25°F (
－4°C)], the pressure
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
indicator comes on while you are
driving in cold weather.
• Blinks - Have the vehicle checked by
an authorized Civic Natural Gas dealer
as soon as possible.

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 doing so, turn off all electrical accessories
(the lights, heating and cooling system, and rear
defogger) in order to reduce battery drain.
If you regularly drive in very cold weather (below
-4°F [-20°C]), consider having an engine block
h e a t e r.
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.
Brake Pedal
1. Make sure the parking brake is applied.
2. Check that the shift lever is in P
, then
depress the brake pedal.
Although it is possible to start the vehicle
in
N, it is safer to start it in P.

3. Turn the ignition switch to ON II without
depressing the accelerator pedal.
You may hear a click from the in-tank fuel
shut-off valve.
4. Turn the ignition switch to START III
without depressing the accelerator pedal.
Starting the Engine
Do not hold the key in START
III for more than 15
seconds.
If the engine does not start right away, wait for at

•least 10 seconds before trying again.
If the engine starts, but then immediately stops,

•wait at least 10 seconds before repeating step
4 while gently depressing the accelerator pedal.
Release the accelerator pedal once the engine
starts.
The immobilizer system protects your vehicle from
theft. If an improperly coded key (or other device) is
used, the engine’s fuel system is disabled. Immobilizer Syste m

After extended storage: If you ever parked your
vehicle for an extended period, open the trunk for
several minutes before starting the engine to allow
any natural gas vapors that may have accumulated
to dissipate.

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: 7.2 gasoline gallon equivalent (3,000 psi)
8.0 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 dealer for your CNG vehicle.
NOTICE Using fast fill equipment at temperature below -4°F
(-20°C) may damage the fuel system, potentially
causing a leak.

Driving
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
r e a r.
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.
5
. Securely connect the CNG fill nozzle to the
fuel receptacle.
