damage your vehicle’s emissions controls and engine. Those repairs may not be covered by your vehicle’s warranties.

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.

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

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

300

).

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

Brake System Indicator

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

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 348

Emergency ).

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

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 346
fuse box lid, which fuse or fuses control that device. The diagram for the interior driver’s side fuse box is on the kick panel below the fuse box. 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.

344

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. 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 that anything is wrong. Replace the fuse with one of the correct rating as soon as you can.

09/07/02 17:26:49 31SNA640_350

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 with your vehicle. Leave the blown fuse in that circuit, and have your vehicle checked by a qualified technician.

If the radio fuse is removed, the audio system may disable itself. The next time you turn on the radio, you will see ‘‘ENTER CODE’’ in the frequency display. Use the preset buttons to enter the five-digit code (see page

206

).

When the audio system is disabled, the clock setting in the audio system will be canceled. You will need to reset the clock (see page

207

Emergency Towing

If your vehicle needs to be towed, call a professional towing service or organization. Never tow your vehicle with just a rope or chain. It is very dangerous.

There are two ways to tow your vehicle:

This is an acceptable

348

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, do not tow the vehicle more than 50
miles (80 km), and keep the speed below 35 mph (55 km/h).

If, due to damage, your vehicle must be towed with the front wheels on the ground, do this:

Manualtransmission:

Release the parking brake. Shift the transmission to neutral. Leave the ignition switch in the ACCESSORY (I) position so the steering wheel does not lock.

Automatictransmission:

Start the engine. Press on the brake pedal. Move the shift lever through all its positions. Shift to D position and hold for 5
seconds, then to N. Turn off the engine. Release the parking brake. Leave the ignition switch in the ACCESSORY (I) position so the steering wheel does not lock.

09/07/02 17:27:31 31SNA640_354

Do not tie down the vehicle at an angle that would allow the towing cables to contact the vehicle’s front bumper. To avoid possible damage, protect the front bumper with tape.

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

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.

Emergency Towing

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

Identification Numbers

Your vehicle has several identifying numbers in various places.

The vehicle identification number (VIN) is the 17-digit number your 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 attached to the driver’s doorjamb, and is stamped on the engine compartment bulkhead. The VIN is also provided in bar code on the certification label.

The VIN is also located on the engine bulkhead. Slide the cover on the engine compartment bulkhead to view the VIN. Always close the cover when finished.

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 tread shoulder and 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.

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.

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.

357

09/07/02 17:29:07 31SNA640_363

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 overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

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.

Tire Pressure Monitoring System (TPMS)

−

Required Federal Explanation

U.S.modelsonly Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label.

(If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale

when one or more of your tires is significantly under-inflated.

Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure.

Driving on a significantly under- inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

Tire Pressure Monitoring System (TPMS)

−

Required Federal Explanation

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is provided by a separate telltale, which displays the symbol ‘‘TPMS’’ when illuminated.

Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

When the malfunction indicator is illuminated,

the system may not be able to detect or signal low tire pressure as intended.

TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.

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.

＊

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 crankcase ventilation valve routes them from the crankcase back to the

Emissions Controls

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.

363

09/07/02 17:30:10 31SNA640_369

Emissions Controls

Exhaust Emissions Controls The exhaust emissions controls include three or four systems: PGM-FI, ignition timing control, exhaust gas recirculation, and three way catalytic converter. These systems work together to control the engine’s combustion and minimize the amount of HC, CO, and NOx that come 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 powertrain control module (PCM) in automatic transmission vehicles or the engine control module (ECM) in manual transmission vehicles uses various sensors to determine how much air is going into the engine. It

364

then controls how much fuel to inject under all operating conditions.

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

ExhaustGasRecirculation(EGR) System ExceptSimodel 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.

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.

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 ), nitrogen (N ), and water vapor.

THREE WAY CATALYTIC CONVERTER

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 combustible materials that come near it. Park your vehicle away from high grass, dry leaves, or other flammables.

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 Converter

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

Keep the engine well maintained.

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

Emissions Testing

Testing of Readiness Codes If you take your vehicle for an 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.

366

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 retested within the next two or three days, you can condition the vehicle for retesting by doing the following.

1.

2.

3.

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 6
hours or more.

Make sure the ambient temperature is between 40° and 95°F (4° and 35°C).

4.

5.

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 (about 3 minutes).

6.

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

Emissions Testing

7.

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 (automatic) or 5th (manual). 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).

8.

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.

9.

Make sure the vehicle has been parked with the engine off for 30
minutes.

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