Introduction

Your Civic GX runs on CompressedNatural Gas (CNG), a highlypressurized version of the sameclean-burning natural gas used inyour home. Because natural gasdoes not contain impurities such assulfur, the production of oxides ofsulfur (SOx) and soot pollutants iseliminated. Using CNG as a fuel alsominimizes the amount of CO2 in theengine exhaust, producing muchlower emissions than a conventionalgasoline-powered vehicle.

Your Civic GX operates andperforms like a gasoline-poweredCivic. However, there are a fewdifferences you should be aware of.In addition to reading the CivicSedan owner's manual, please readthis supplement carefully tounderstand the operation and uniquefeatures of your Civic GX.

You will find important safetyinformation in this supplement andin the owner's manual. Thisinformation alerts you to potentialhazards that could hurt you or others.Please read it carefully.

Indicator Lights

Malfunction IndicatorLamp

This indicator comes on for a fewseconds when you turn the ignitionswitch ON (II). If it comes on at anyother time, it indicates one of theengine's emissions control systemsmay have a problem. For completeinformation, refer to the primaryowner's manual.

This indicator will also come on ifthere is a problem in the fuel system.If this happens, have the vehiclechecked by an authorized dealer assoon as possible. Drive moderatelyuntil the dealer has inspected theproblem. Avoid full-throttleacceleration and driving at highspeed.

Instruments and Controls

MALFUNCTION INDICATOR LAMP LOW FUEL INDICATOR

Indicator Lights

If you smell natural gas or hear ahissing sound, the fuel system mayhave a leak. Follow the instructionsunder If the Fuel System Has aLeak on page 40 of this supplement.

Low Fuel Indicator

This indicator comes on for a fewseconds when you turn ignition on(I I).This light comes on as a reminderthat you must refuel soon.

If the outside temperature fallsbelow 25° F ( — 4° C), the pressure ofthe natural gas in the fuel tank maygo down. If this happens, the fuelgauge will show less than the actualamount of fuel remaining, and thisindicator may come on.

If this indicator starts blinking andthe fuel level reading goes down toempty when the engine is running, itindicates a problem in the fuelsystem. Have the vehicle checked byan authorized Honda Civic GX dealeras soon as possible.


Gauges

Fuel Gauge

This gauge shows how much fuelyou have. The quantity of fuelremaining in the tank is calculatedbased on the pressure andtemperature of the natural gas in thefuel tank.

The gauge may show slightly moreor less than the actual amount. Theoutside temperature and ambientconditions may affect the pressureand temperature of the natural gas.

The gauge stays at the same fuellevel reading after you turn off theignition. When you add fuel, thegauge slowly changes to the newreading after you turn the ignitionswitch back ON (II).


FUEL GAUGE

Rear Seat

Unlike the standard Civic, only twopeople can ride in the rear seat. Theyshould sit in the outside seatingpositions and wear the lap/shoulderbelts. There is no center seat belt.


Fuel

Your Civic GX is designed to operateon Compressed Natural Gas (CNG).The natural gas you use to refuelmust meet NFPA-52 and SAE J1616standards for fuel composition andquality.

If you use a fuel that does not meetthese standards, you may feel adecrease in engine power and yourcar's emissions controls may bedamaged.

Compressed Natural Gas (CNG)The main component of compressednatural gas is methane, a highlyflammable, colorless gas. While it isthe same gas that is burned ineveryday home appliances such askitchen stoves and water heaters,the CNG in your car is stored underhigh pressure (maximum 3,600 psi/24,800 kPa).

The CNG fuel system in your Civic,including the tank and hose, hasbeen designed to hold gas at thispressure. It has also been tested forsafety. You should never smell gasor hear a hissing sound unless youare refueling. If you smell gas orhear a hissing sound at any othertime, you need to shut down the fuelsystem. Follow the instructions onpage 40.

Before Driving

Compressed natural gas isflammable and highly explosive.You could be killed or seriouslyinjured if leaking natural gas isignited.

If you suspect a leak, have yourvehicle immediately inspectedand repaired by an authorizedHonda Civic GX dealer.

Fuel, Refueling Procedure

Your vehicle has an identifying"CNG" label attached next to therear license plate. Do not removethis label. This label is necessary forinsuring your vehicle. Drivingwithout this label may violate thelaws or regulations in some states.

Refueling ProcedureThere are two methods of refueling,fast filling or slow filling.

Fast filling is normally used in fuelstations for natural gas vehicles. Ittakes about three to five minutes tofill up the fuel tank.

Slow filling is done with a vehiclerefueling appliance. Refueling takesapproximately 1 hour per gallon.

Always observe all safetyrecommendations and operatinginstructions on the refuelingequipment.

When refueling, you should use afuel fill nozzle that complies withANSI/AGA NGV-1-1994 standards.Nozzles are designed according totheir maximum fill pressure: P24 for2,400 psi (pounds per square inch),P30 for 3,000 psi, and P36 for 3,600psi.

Your Civic's maximum fill pressureis 3,600 psi (24,800 kPa), so youshould refuel with a P36 nozzle.Using a P24 or P30 nozzle may causethe tank to not fill completely.

The natural gas may be warmed bythe refueling process, causing it toexpand and reduce the amount offuel you can put in.

Refueling Procedure

Filling the Fuel TankThe refueling procedure can varywith the refueling station. Thefollowing explains the typicalrefueling procedure with fast fillequipment. With slow fil l equipment,or other types of refuelingequipment, follow the instructions onthe equipment.

1. Because the fuel receptacle is onthe driver's side of the vehicle,park with that side closest to therefueling station.

2. Turn the ignition switch to LOCK(0) and apply the parking brake.

3. Open the fuel receptacle door bypushing on the handle to the leftof the driver's seat.

4. Remove the receptacle dust capfrom the fuel receptacle. Clean upany dirt and debris around the fuelreceptacle.

Before Driving

Refueling Procedure

5. Securely connect the CNG fillnozzle to the fuel receptacle byturning the lever until the arrowson the nozzle point to each other.

6. Follow the instructions on therefueling station to begin refueling.

While refueling, you may hear achattering sound. This is normal.

If you hear fuel leaking from thenozzle-receptacle connection, stoprefueling immediately. Dirt orother debris may be preventing apositive connection. Turn off therefueling station, remove thenozzle, reconnect it to thereceptacle, and begin refuelingagain. If it continues to leak, havean authorized Honda Civic GXdealer inspect the sealing O-ring inthe receptacle for damage andwear.

7. Refueling will stop automaticallywhen the tank is full. Follow theinstructions on the refuelingstation to turn it off.

8. Disconnect the CNG fill nozzlefrom the fuel receptacle byturning the lever on the nozzle 180degrees. You may hear a briefhissing sound as a small amount ofgas escapes. This is normal.

Before Driving

Refueling Procedure

9. Put the receptacle dust cap on thefuel receptacle securely.

10.Push the fuel receptacle doorclosed until it latches.

If you are not sure how to operatethe refueling station, ask forassistance.

Fuel Cut-off System, Carrying Cargo

To turn off the valve, turn the leverone-quarter turn clockwise. Turn itcounterclockwise to turn the valveback on.

Turn off the valve if you ever suspecta fuel leak or are involved in anaccident.

Carrying CargoThe maximum load you can carry inyour car is 635 Ibs (288 kg). Thatfigure includes the total weight offour occupants (driver and threepassengers), their cargo, and anyaccessories. The maximumrecommended weight for cargo inthe trunk is 35 Ibs (16 kg).

The fuel tank is located in the trunk,with a partition between the fueltank and the cargo space.

When you store small items in thetrunk, secure them so they will notshift while you are driving. Looseitems can fly over the partition anddamage the fuel tank and fuelsystem components.

Do not carry large, heavy or pointedobjects in the trunk. They maydamage the fuel tank.

Before Driving

Starting the Engine

1. Apply the parking brake.

2. In cold weather, turn off allelectrical accessories to reducethe drain on the battery.

3. Make sure the shift lever is inPark. Press on the brake pedal.

4. Without touching the acceleratorpedal, turn the ignition key to theON (II) position. You may hear aclick from the in-tank fuel shut-offvalve.

Make sure the MalfunctionIndicator Lamp goes out beforeyou turn the ignition key to theSTART (III) position.

5. Turn the ignition key to START(III). If the engine does not startright away, do not hold the key inSTART (III) for more than 15seconds at a time. Pause for atleast 10 seconds before tryingagain.

6. If the engine does not start within15 seconds, or starts but stallsright away, repeat step 5 with theaccelerator pedal pressed half-waydown. If the engine starts, releasepressure on the accelerator pedalso the engine does not race.

7. If the engine still does not start,press the accelerator pedal all theway down and hold it there whilestarting. As before, keep theignition key in the START (III)position for no more than 15seconds. Return to step 6 if theengine does not start. If it starts,lift your foot off the acceleratorpedal so the engine does not race.

If the outside temperature is below— 4°F ( — 20°C), the engine may beharder to start. In this case, use thestarting procedure for cold weatherat high altitude described in the nextcolumn.

Starting in Cold Weather at HighAltitude (Above 5,000 feet/1,600 meters)An engine is harder to start in coldweather. The thinner air found athigh altitude above 5,000 feet (1,600meters) adds to the problem.Use the following procedure:

1. Turn off all electrical accessoriesto reduce the drain on the battery.

2. Make sure the MalfunctionIndicator Lamp goes out beforeyou turn the ignition key to theSTART (III) position.

SHIFT LEVER

RELEASE BUTTON


Park (P) — This positionmechanically locks the transmission.Use Park whenever you are turningoff or starting the engine. To shiftout of Park, you must press on thebrake pedal, have your foot off theaccelerator pedal, and press therelease button on the front of theshift lever.

If you have done all of the above andstill cannot move the lever out ofPark, see Shift Lock Release in themain Owner's manual.

You must also press the releasebutton to shift into Park. To avoidtransmission damage, come to acomplete stop before shifting intoPark. The shift lever must be in Parkbefore you can remove the key fromthe ignition switch.

Reverse (R) —To shift from Re-verse to under Park. To shift to Reverse fromNeutral, come to a complete stopfirst. Press the release button beforeshifting into Reverse from Neutral.

Neutral (N) — Use Neutral if youneed to restart a stalled engine, or ifit is necessary to stop briefly withthe engine idling. Shift to Park posi-tion if you need to leave the car forany reason. Press on the brake pedalwhen you are moving the shift leverfrom Neutral to another gear.

Drive (D) — Use this position foryour normal driving. The transmis-sion automatically adjusts to keepthe engine at the best speed fordriving conditions. To help theengine warm up faster, the transmis-sion will select ratios that allow theengine to run at higher speeds whenit is cold.

Driving


Second (S) — Selecting Secondshifts the transmission into a lowerrange of ratios for better accelera-tion and increased engine braking.Use Second when you are goingdown a steep hill, or in stop-and-godriving.

Low (L) — To shift to Low, pressthe release button on the front of theshift lever. Use Low to get morepower when climbing, and formaximum engine braking whengoing down steep hills.

For faster acceleration when in D, Sor L, the transmission willautomatically "kick down" to a lowerrange of ratios by pushing theaccelerator pedal to the floor.

Maximum Allowable SpeedsThe CVT shifts automatically tomaintain proper engine speed in anyshift position.

When the vehicle reaches themaximum speed in any shift position,you may feel the engine cut in andout. This is caused by a limiter (112mph, 180 km/h) in the engine'scomputer controls. The engine willrun normally when you reduce thespeed below the maximum.

If the Fuel System Has a Leak

You may detect a slight natural gasodor for a few moments afterrefueling. This is normal. You shouldnot be able to smell natural gas atany other time. If you do, or if youhear a hissing sound, your vehicle'sfuel system may have a leak.

If this happens, follow thesedirections:

1. Park your vehicle in a well-ventilated area and apply theparking brake.Keep heat, sparks, and flame away.Open all the windows and thetrunk lid for ventilation.

2. Turn the ignition switch to theLOCK (0) position.

3. Turn the manual shut-off valve tothe OFF position to shut off thenatural gas (see Manual Shut-offValve on page 13 in thissupplement).

You cannot continue driving. Yourvehicle should be towed to anauthorized Honda Civic GX dealer(see Emergency Towing in theprimary owner's manual).


Compressed natural gas isflammable and highly explosive.You could be killed or seriouslyinjured if leaking natural gas isignited.

If you suspect a leak, have yourvehicle immediately inspectedand repaired by an authorizedHonda Civic GX dealer.

Jump Starting


Do not jump start your vehicle if yoususpect a natural gas leak. If yousmell natural gas or hear a hissingsound, the fuel system may have aleak that needs to be repaired by anauthorized technician.

Turn the manual shut-off valve to theOFF position and have your vehicletowed to an authorized Honda CivicGX dealer (see Emergency Towingin the primary owner's manual).

Emissions Controls

The burning of compressed naturalgas in your vehicle's engineminimizes the production of severalbyproducts. Some of these arecarbon monoxide (CO), oxides ofnitrogen (NOx) and hydrocarbons(HC). Controlling the production ofNOx, CO, and HC is important to theenvironment. Under certainconditions of sunlight and climate,NOx and HC react to formphotochemical "smog." Carbonmonoxide does not contribute tosmog creation, but it is a poisonousgas.

The Clean Air ActThe United States Clean Air Act setsstandards for automobile emissions.It also requires that automobilemanufacturers explain to ownershow their emissions controls workand what to do to maintain them.This section summarizes how theemissions controls work. Scheduledmaintenance is on page 196 in theprimary owner's manual.

Crankcase Emissions ControlSystemYour vehicle has a PositiveCrankcase Ventilation System. Thiskeeps gasses that build up in theengine's crankcase from going intothe atmosphere. The Positive Crank-case Ventilation valve routes themfrom the crankcase back to theintake manifold. They are thendrawn into the engine and burned.


Emissions Controls

Exhaust Emissions ControlsThe exhaust emissions controlsinclude four systems: PGM-FI,Ignition Timing Control, ExhaustGas Recirculation, and Three WayCatalytic Converters. These foursystems work together to control theengine's combustion and minimizethe amount of HC, CO, and NOx thatcomes out the tailpipe. The exhaustemissions control systems areseparate from the crankcaseemissions control system.

PGM-FI SystemThe PGM-FI System uses sequentialmultiport fuel injection.It has three subsystems: Air Intake,Engine Control, and Fuel Control.The Powertrain Control Module(PCM) uses various sensors todetermine how much air is goinginto the engine. It then controls howmuch fuel to inject under all operat-ing conditions.

Ignition Timing Control SystemThis system constantly adjusts theignition timing, reducing the amountof HC, CO and NOx produced.

Exhaust Gas Recirculation (EGR)SystemThe Exhaust Gas Recirculation(EGR) system takes some of theexhaust gas and routes it back intothe intake manifold. Adding exhaustgas to the air/fuel mixture reducesthe amount of NOx produced whenthe fuel is burned.

Three Way Catalytic ConvertersThe three way catalytic convertersare in the exhaust system. Throughchemical reactions, they convert HC,CO, and NOx in the engine's exhaustto carbon dioxide (CO2), dinitrogen(Na), and water vapor.

Replacement PartsThe emissions control systems aredesigned and certified to work to-gether in reducing emissions tolevels that comply with the Clean AirAct. To make sure the emissionsremain low, you should use only newgenuine Honda replacement parts ortheir equivalent for repairs. Usinglower quality parts may increase theemissions from your vehicle.

The emissions control systems arecovered by warranties separate fromthe rest of your vehicle. Read yourwarranty manual for more informa-tion.
