Using gloves or large heavy cloth, turn the radiator cap counterclockwise without pushing down to the first stop. After the pressure releases, push down on the cap, and turn it until it comes off.

’’). Add coolant

Start the engine and set the temperature control dial to maximum (climate control to AUTO at ‘‘ to the radiator up to the base of the filler neck. If you do not have the proper coolant mixture available, you can add plain water. Remember to have the cooling system drained and refilled with the proper mixture as soon as you can.

10.

Put the radiator cap back on tightly. Run the engine and watch the temperature gauge. If it goes back to the red mark, the engine needs repair (see Towing on page

Emergency 272

).

11.

If the temperature stays normal, check the coolant level in the radiator reserve tank. If it has gone down, add coolant to the MAX mark. Put the cap back on tightly.

Running the engine with low oil pressure can cause serious mechanical damage almost immediately.Turn of f the engine as soon as you can saf ely get the vehicle stopped.

Start the engine, and watch the oil pressure indicator. If it does not go out within 10 seconds, turn off the engine. There is a mechanical problem that needs to be repaired before you can continue driving (see 272

Emergency Towing ).

on page

Safely pull off the road, and shut off the engine. Turn on the hazard warning indicators.

Let the vehicle sit for a minute. Open the hood, and check the oil level (see page ). An engine very low on oil can lose pressure during cornering and other driving maneuvers.

168

If necessary, add oil to bring the level back to the full mark on the dipstick (see page

217

).

This indicator should never come on when the engine is running. If it starts flashing or stays on, the oil pressure has dropped very low or lost pressure. Serious engine damage is possible and you should take immediate action.

Malfunction Indicator Lamp

MALFUNCTION INDICATOR LAMP

Immediately turn off all electrical accessories. Try not to use other electrically operated controls such as the power windows. Keep the engine running; starting the engine will discharge the battery rapidly.

Go to a Honda dealer or a service station where you can get technical assistance.

If the indicator comes on while driving, it means one of the engine’s emissions control systems may have a problem. Even though you may feel no difference in your vehicle’s performance, it can reduce your fuel economy and cause increased emissions. Continued operation may cause serious damage.

Readiness Codes Your vehicle has certain ‘‘readiness codes’’ that are part of the on-board diagnostics for the emissions systems. In some states, part of the emissions testing is to make sure these codes are set. If they are not set, the test cannot be completed.

If your vehicle battery has been disconnected or gone dead, these codes are erased. It takes at least three days of driving under various conditions to set the codes again.

Malfunction Indicator Lamp

If you have recently refueled your vehicle, the indicator could come on because of a loose or missing fuel fill cap. Tighten the cap until it clicks at least three times. Tightening the cap will not turn the indicator turn off immediately; it takes at least three days of normal driving.

If the indicator remains on, or the fuel cap was not loose or missing, have your vehicle checked by the dealer as soon as possible.

If you keep driving with the Malf unction Indicator Lamp on, you can damage your vehicle’s emissions controls and the engine. Those repairs may not be covered by your vehicle’s warranties.

This indicator may also come on along with the ‘‘D’’ indicator.

270

Taking Care of the Unexpected

To check if they are set, turn the ignition switch to ON (II), without starting the engine. The Malfunction Indicator Lamp will come on for 20
seconds. If it then goes off, the readiness codes are set. If it blinks 5
times, the readiness codes are not set. If possible, do not take your vehicle for a state emissions test until the readiness codes are set. Refer to State Emissions Testing for more information (see page

296

).

Brake System Indicator

BRAKE SYSTEM INDICATOR

＊

If the brake system indicator comes on while driving, the brake fluid level is probably low. Press lightly on the brake pedal to see if it feels normal. If it does, check the brake fluid level the next time you stop at a service station (see page

230

).

U.S. indicator shown ＊

The brake system indicator normally comes on when you turn the ignition switch to ON (II) and as a reminder to check the parking brake. It will stay lit if you do not fully release the parking brake.

If the fluid level is low, take your vehicle to the dealer and have the brake system inspected for leaks or worn brake pads.

However, if the brake pedal does not feel normal, you should take immediate action. A problem in one part of the system’s dual circuit design will still give you braking at two wheels. You will feel the brake pedal go down much farther before the vehicle begins to slow down and you will have to press harder on the pedal.

Slow down by shifting to a lower gear, and pull to the side of the road when it is safe. Because of the long distance needed to stop, it is hazardous to drive the vehicle. You should have it towed and repaired as soon as possible (see Towing 272

Emergency ).

on page

If you must drive the vehicle a short distance in this condition, drive slowly and carefully.

If the ABS indicator comes on with the brake system indicator, have the vehicle inspected by your Honda dealer immediately.

If your Honda cannot be transported by flat-bed, it should be towed by wheel-lift equipment with the front wheels off the ground. If, due to damage, your vehicle must be towed with the front wheels on the ground, do the following:

ManualTransmission:

Release the parking brake. Shift the transmission to Neutral.

AutomaticTransmission:

Release the parking brake. Start the engine. Shift to D, then to N. Turn off the engine.

Improper towing preparation will damage the transmission. Follow the above procedure exactly. If you cannot shif t the transmission or start the engine (automatic transmission), your vehicle must be transported with the f ront wheels of f the ground.

With the front wheels on the ground, it is best to tow the vehicle no farther than 50 miles (80 km), and keep the speed below 35 mph (55 km/h).

If your vehicle is equipped with a front spoiler, remove it before towing so it is not damaged.

Emergency Towing

Trying to lif t or tow your vehicle by the bumpers will cause serious damage. The bumpers are not designed to support the vehicle’s weight.

If you decide to tow your vehicle with all four wheels on the ground, make sure you use a properly- designed and attached tow bar. Prepare the vehicle for towing as described above, and leave the ignition switch in Accessory (I) so the steering wheel does not lock. Make sure the radio and any items plugged into the accessory power socket are turned off so they do not run down the battery.

The steering system can be damaged if the steering wheel is locked. Leave the ignition switch in Accessory (I), and make sure the steering wheel turns f reely bef ore you begin towing.

Closing the Moonroof

OnEXandEX-V6models If the electric motor will not close the moonroof, do the following:

1.

2.

Check the fuse for the moonroof motor (see page ). If the fuse is blown, replace it with one of the same or lower rating.

279

Try closing the moonroof. If the new fuse blows immediately or the moonroof motor still does not operate, you can close the moonroof manually.

3.

Get the moonroof wrench out of the tool kit in the trunk.

4.

To remove the round plug in the center of the headliner, turn the plug by using a screwdriver or coin, then pry it out. Make sure to align the tabs on the round plug to the notches on the ceilling as shown in the illustration.

Checking and Replacing Fuses If something electrical in your vehicle stops working, the first thing you should check for is a blown fuse. Determine from the chart on pages , or the diagram on the 278
fuse box lid, which fuse or fuses control that device. Check those fuses first, but check all the fuses before deciding that a blown fuse is the cause. Replace any blown fuses, and check if the device works.

279

The vehicle’s fuses are located in two fuse boxes.

The interior fuse box is on the driver’s lower left side. To remove the fuse box lid, put your finger in the notch on the lid, and pull it upward slightly, then pull it toward you and take it out of its hinges.

The under-hood fuse box is located on the driver’s side. To open it, push the tabs as shown.

1.

Turn the ignition switch to LOCK (0). Make sure the headlights and all other accessories are off.

2.

Remove the cover from the fuse box.

5.

Look for a burned wire inside the fuse. If it is burned, replace it with one of the spare fuses of the same rating or lower.

Fuses

If you cannot drive the vehicle without fixing the problem, and you do not have a spare fuse, take a fuse of the same rating or a lower rating from one of the other circuits with the fuse puller provided in the under- hood fuse box. Make sure you can do without that circuit temporarily (such as the accessory power socket or radio).

If you replace the blown fuse with a spare fuse that has a lower rating, it might blow out again. This does not indicate anything wrong. Replace the fuse with one of the correct rating as soon as you can.

Replacing a f use with one that has a higher rating greatly increases the chances of damaging the electrical system. If you do not have a replacement f use with the proper rating f or the circuit, install one with a lower rating.

6.

If the replacement fuse of the same rating blows in a short time, there is probably a serious electrical problem in your vehicle. Leave the blown fuse in that circuit, and have your vehicle checked by a qualified mechanic.

Identification Numbers

Your vehicle has several identifying numbers in various places.

The Vehicle Identification Number (VIN) is the 17-digit number your Honda dealer uses to register your vehicle for warranty purposes. It is also necessary for licensing and insuring your vehicle. The easiest place to find the VIN is on a plate fastened to the top of the dashboard. You can see it by looking through the windshield on the driver’s side. It is also on the Certification label at- tached to the driver’s doorjamb, and is stamped on the engine com- partment bulkhead. The VIN is also provided in bar code on the Certification label.

DOT Tire Quality Grading (U.S. Vehicles)

Treadwear The treadwear grade is a compara- tive rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one- half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual condi- tions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

The tires on your vehicle meet all U.S. Federal Safety Requirements. All tires are also graded for treadwear, traction, and temperature performance according to Department of Transportation (DOT) standards. The following explains these gradings.

Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between the tread shoulder and the maximum section width. For example:

Treadwear 200
Traction AA Temperature A

All passenger car tires must conform to Federal Safety Requirements in addition to these grades.

288

Technical Information

−

AA, A, B, C

Traction The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

Temperature The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

DOT Tire Quality Grading (U.S. Vehicles)

Warning: The temperature grade for this tire is established for a tire that is properly inflated and not over- loaded. Excessive speed, underinfla- tion, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions.

If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement.

Before using an oxygenated fuel, try to confirm the fuel’s contents. Some states/provinces require this information to be posted on the pump.

The following are the U.S. EPA and Canadian CGSB approved percentages of oxygenates:

ETHANOL (ethyl or grain alcohol) You may use gasoline containing up to 10 percent ethanol by volume. Gasoline containing ethanol may be marketed under the name ‘‘Gasohol.’’

(Methyl Tertiary Butyl

MTBE Ether) You may use gasoline containing up to 15 percent MTBE by volume.

(methyl or wood

METHANOL alcohol) Your vehicle was not designed to use fuel that contains methanol. Methanol can corrode metal parts in the fuel system, and also damage plastic and rubber components. This damage would not be covered by your warranties.

Oxygenated Fuels

If you notice any undesirable operating symptoms, try another service station or switch to another brand of gasoline.

Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates given above are not covered under warranty.

Driving in Foreign Countries

If you are planning to take your Honda outside the U.S. or Canada, contact the tourist bureaus in the areas you will be traveling in to find out about the availability of unleaded gasoline with the proper octane rating.

If unleaded gasoline is not available, be aware that using leaded gasoline in your Honda will affect perfor- mance and fuel mileage, and damage its emissions controls. It will no longer comply with U.S. and Canadian emissions regulations, and will be illegal to operate in North America. To bring your vehicle back into compliance will require the re- placement of several components, such as the oxygen sensors and the three way catalytic converter. These replacements are not covered under warranty.

The burning of gasoline in your vehicle’s engine produces several by- products. Some of these are carbon monoxide (CO), oxides of nitrogen (NOx) and hydrocarbons (HC). Gasoline evaporating from the tank also produces hydrocarbons. Con- trolling the production of NOx, CO, and HC is important to the environ- ment. Under certain conditions of sunlight and climate, NOx and HC react to form photochemical ‘‘smog.’’ Carbon monoxide does not contri- bute to smog creation, but it is a poisonous gas.

The Clean Air Act The United States Clean Air Act sets standards for automobile emissions. It also requires that automobile manufacturers explain to owners how their emissions controls work and what to do to maintain them. This section summarizes how the emissions controls work. Scheduled maintenance is on pages 205

In Canada, Honda vehicles comply

with the Canadian emission requirements, as specified in an agreement with Environment Canada, at the time they are manufactured.

Crankcase Emissions Control System Your vehicle has a Positive Crankcase Ventilation System. This keeps gasses that build up in the engine’s crankcase from going into the atmosphere. The Positive Crank-

Emissions Controls

case Ventilation valve routes them from the crankcase back to the intake manifold. They are then drawn into the engine and burned.

Evaporative Emissions Control System As gasoline evaporates in the fuel tank, an evaporative emissions control canister filled with charcoal adsorbs the vapor. It is stored in this canister while the engine is off. After the engine is started and warmed up, the vapor is drawn into the engine and burned during driving.

Onboard Refueling Vapor Recovery The Onboard Refueling Vapor Recovery (ORVR) system captures the fuel vapors during refueling. The vapors are adsorbed in a canister filled with activated carbon. While driving, the fuel vapors are drawn into the engine and burned off.

Emissions Controls

Exhaust Emissions Controls The exhaust emissions controls include four systems: PGM-FI, Ignition Timing Control, Exhaust Gas Recirculation and Three Way Catalytic Converter. These four systems work together to control the engine’s combustion and minimize the amount of HC, CO, and NOx that comes out the tailpipe. The exhaust emissions control systems are separate from the crankcase and evaporative emissions control systems.

PGM-FISystem The PGM-FI System uses sequential multiport fuel injection. It has three subsystems: Air Intake, Engine Control, and Fuel Control. The Engine Control Module (ECM) or the Powertrain Control Module (PCM) uses various sensors to determine how much air is going into the engine. It then controls how much fuel to inject under all operat-

Technical Information

Replacement Parts The emissions control systems are designed and certified to work to- gether in reducing emissions to levels that comply with the Clean Air Act. To make sure the emissions remain low, you should use only new Honda replacement parts or their equivalent for repairs. Using lower quality parts may increase the emissions from your vehicle.

The emissions control systems are covered by warranties separate from the rest of your vehicle. Read your warranty manual for more informa- tion.

ing conditions.

IgnitionTimingControlSystem This system constantly adjusts the ignition timing, reducing the amount of HC, CO, and NOx produced.

ExhaustGasRecirculation(EGR) System The Exhaust Gas Recirculation (EGR) system takes some of the exhaust gas and routes it back into the intake manifold. Adding exhaust gas to the air/fuel mixture reduces the amount of NOx produced when the fuel is burned.

ThreeWayCatalyticConverter The three way catalytic converter is in the exhaust system. Through chemical reactions, it converts HC, CO, and NOx in the engine’s exhaust to carbon dioxide (CO ), dinitrogen (N ), and water vapor.

Main MenustTable of Contents０３／０７／２６　１９：５４：１３　３１ＳＤＰ６１０　０２９８　

Three Way Catalytic Converter

The three way catalytic converter contains precious metals that serve as catalysts, promoting chemical reactions to convert the exhaust gasses without affecting the metals. The catalytic converter is referred to as a three-way catalyst, since it acts on HC, CO, and NOx. A replacement unit must be an original Honda part or its equivalent.

The three way catalytic converter must operate at a high temperature for the chemical reactions to take place. It can set on fire any com- bustible materials that come near it. Park your vehicle away from high grass, dry leaves, or other flamma- bles.

THREE WAY CATALYTIC CONVERTER 4-cylinder models A defective three way catalytic converter contributes to air pollution, and can impair your engine’s per- formance. Follow these guidelines to protect your vehicle’s three way catalytic converter.

THREE WAY CATALYTIC CONVERTERS 6-cylinder models Keep the engine tuned-up.

Have your vehicle diagnosed and repaired if it is misfiring, back- firing, stalling, or otherwise not running properly.

Always use unleaded gasoline. Even a small amount of leaded gasoline can contaminate the catalyst metals, making the three way catalytic converter ineffective.

State Emissions Testing

Testing of Readiness Codes If you take your vehicle for a state emissions test shortly after the battery has been disconnected or gone dead, it may not pass the test. This is because of certain ‘‘readiness codes’’ that must be set in the on- board diagnostics for the emissions systems. These codes are erased when the battery is disconnected, and set again only after several days of driving under a variety of conditions.

296

Technical Information

Without touching the accelerator pedal, start the engine, and let it idle for 20 seconds.

Keep the vehicle in Park (automatic transmission) or Neutral (manual transmission). Increase the engine speed to 2,000
rpm and hold it there until the temperature gauge rises to at least 1/4 of the scale (approximately 3
minutes).

If the testing facility determines that the readiness codes are not set, you will be requested to return at a later date to complete the test. If you must get the vehicle re-tested within the next two or three days, you can condition the vehicle for re-testing by doing the following.

Make sure the gas tank is nearly, but not completely, full (around 3/4).

Make sure the vehicle has been parked with the engine off for 8
hours or more.

Make sure the ambient temperature is between 20° and 95°F.

State Emissions Testing

Select a nearby lightly traveled major highway where you can maintain a speed of 50 to 60 mph (80 to 97 km/h) for at least 20
minutes. Drive on the highway in D (A/T) or 5th/6th (M/T). Do not use the cruise control. When traffic allows, drive for 90 seconds without moving the accelerator pedal. (Vehicle speed may vary slightly; this is okay.) If you cannot do this for a continuous 90
seconds because of traffic conditions, drive for at least 30
seconds, then repeat it two more times (for a total of 90 seconds).

Then drive in city/suburban traffic for at least 10 minutes. When traffic conditions allow, let the vehicle coast for several seconds without using the accelerator pedal or the brake pedal.

If the testing facility determines the readiness codes are still not set, see your Honda dealer.
