Jump Starting

Although this seems like a simple procedure, you should take several precautions.

A battery can explode if you do not follow the correct procedure, seriously injuring anyone nearby.

Keep all sparks, open flames, and smoking materials away from the battery.

162

Taking Care of the Unexpected

ToJumpStartYourVehicle:

1.

Open the hood, and check the physical condition of the battery. In very cold weather, check the condition of the electrolyte. If it seems slushy or like ice, do not try jump starting until it thaws.

NOTICE: If a battery sits in extreme cold, the electrolyte inside can f reeze. Attempting to jump start with a f rozen battery can cause it to rupture.

2.

3.

Turn off all the electrical accessories: heater, A/C, audio system, lights, etc. Put the transmission in Neutral, and set the parking brake.

Jump Starting, If the Engine Overheats

6.

7.

Start the vehicle. If the starter motor still operates slowly, check that the jumper cables have good metal-to-metal contact.

Once your vehicle is running, disconnect the negative cable from your vehicle, then from the booster battery. Disconnect the positive cable from your vehicle, then from the booster battery.

Keep the ends of the jumper cables away from each other and any metal on the vehicle until everything is disconnected. Otherwise, you may cause an electrical short.

If the Engine Overheats The reading on your vehicle’s temperature gauge should stay in the midrange under most conditions. If it reaches the red mark, you should determine the reason (hot day, driving up a steep hill, etc.).

If your vehicle overheats, you should take immediate action. The only indication may be the temperature gauge reading reaching the red mark. Or you may see steam or spray coming from under the hood.

NOTICE: Driving with the temperature gauge reading at the red mark can cause serious damage to your engine.

Taking Care of the Unexpected

163

The numbers in the illustration show you the order to connect the jumper cables.

5.

If the booster battery is in another vehicle, have an assistant start that vehicle and run it at a fast idle.

Main MenustTable of Contents０３／０８／１９　１０：４７：１３　３１Ｓ２Ａ６４０　０１６７　

If the Engine Overheats

Steam and spray from an overheated engine can seriously scald you.

Do not open the hood if steam is coming out.

164

Taking Care of the Unexpected

4.

If the temperature gauge stays at the red mark, turn off the engine.

5.

Look for any obvious coolant leaks, such as a split radiator hose. Everything is still extremely hot, so use caution. If you find a leak, it must be repaired before you Emergency continue driving (see Towing ). 176

on page

6.

If you don’t find an obvious leak, check the coolant level in the radiator reserve tank. Add coolant if the level is below the MIN mark.

1.

2.

3.

Safely pull to the side of the road. Put the transmission in Neutral, and set the parking brake. Turn off the all accessories, and turn on the hazard warning indicators.

If you see steam and/or spray coming from under the hood, turn off the engine. Wait until you see no more signs of steam or spray, then open the hood.

If you do not see steam or spray, leave the engine running, and watch the temperature gauge. If the high heat is due to overloading, the engine should start to cool down almost immediately. If it does, wait until the temperature gauge comes down to the midpoint, then continue driving.

Main MenustTable of Contents０３／０８／１９　１０：４７：２１　３１Ｓ２Ａ６４０　０１６８　

If the Engine Overheats

7.

If there was no coolant in the reserve tank, you may need to add coolant to the radiator. Let the engine cool down until the reading reaches the middle of the temperature gauge, or lower, before checking the radiator.

Removing the radiator cap while the engine is hot can cause the coolant to spray out, seriously scalding you.

Always let the engine and radiator cool down before removing the radiator cap.

8.

9.

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.

Start the engine, and set the temperature control dial to maximum. Add coolant 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 176

).

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.

Low Oil Pressure Indicator, Charging System Indicator

Low Oil Pressure Indicator

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.

NOTICE: 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.

4.

166

Taking Care of the Unexpected

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.

103

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

129

).

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 176

Emergency Towing ).

Charging System Indicator

If the charging system indicator comes on brightly

when the engine is running, the battery is not being charged.

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 service station or garage where you can get technical assistance.

Main MenustTable of Contents０３／０８／１９　１０：４７：４３　３１Ｓ２Ａ６４０　０１７０　

If this indicator comes on while driving, it means one

of the engine’s emission 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.

If you have recently refueled your vehicle, the indicator coming on could be 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 off immediately; it takes at least three days of normal driving.

Malfunction Indicator Lamp

If the indicator comes on repeatedly, even though it may go off as you continue driving, have your vehicle checked by a dealer as soon as possible.

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.

NOTICE: 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.

Readiness Code 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.

To check if they are set, turn the ignition 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, on page

Brake System Indicator

U.S.

Canada

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 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 thenexttimeyoustopataservice station (see page

136

).

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

168

Taking Care of the Unexpected

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 176

Emergency ).

on page

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, check for a blown fuse first. Determine from the chart on pages ,or the diagram on the fuse box lid, which 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.

4.

Check the smaller fuses in the under-hood fuse boxes and all the fuses in the interior fuse box by pulling out each one with the fuse puller provided in the primary under-hood fuse box.

5.

Look for a burned wire inside the fuse. If it is burned, replace it with oneofthesparefusesofthesame rating or lower.

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 sureyoucandowithoutthatcircuit 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

NOTICE: 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.

If the radio fuse is removed, the audio system will disable itself. The next time you turn on the radio you will see ‘‘Code’’ in the frequency display. Use the preset buttons to enter the five-digit code (see page 94

).

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.

182

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.

Main MenustTable of Contents０３／０８／１９　１０：５０：２３　３１Ｓ２Ａ６４０　０１８６　

−

A, B, C

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.

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 page 123

In Canada, Honda vehicles comply

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

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.

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

Exhaust Emissions Controls The exhaust emissions controls include four systems: PGM-FI, Ignition Timing Control, Secondary Air Injection System, 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) uses various sensors to determine how much air is going into the engine. It then controls how much fuel to inject under all operating con- ditions.

186

Technical Information

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

SecondaryAirInjectionSystem During engine warm-up, air is pumped into the exhaust to reduce emissions when the engine is cold.

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.

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.

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.

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

Keep the engine tuned-up.

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

THREE WAY CATALYTIC CONVERTER

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.

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.

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.

188

Technical Information

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

Keep the vehicle in Neutral. 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).

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 5th. 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.
