Main MenuTable of Contentsst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.

You cannot start your vehicle by pushing or pulling it.

248

To jump start your vehicle:

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 frozen, do not try jump starting until it thaws.

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.

Turn off all the electrical accessories: heater, A/C, audio system, lights, etc. Put the transmission in neutral (M/T) or Park (A/T), and set the parking brake.

7.

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

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.

Main MenuTable of ContentsstThe pointer of the vehicle’s temperature gauge should stay in the midrange. If it climbs to 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 climbing to or above the red mark. Or you may see steam or spray coming from under the hood.

Driving with the temperature gauge pointer at the red mark can cause serious damage to the engine.

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

Do not open the hood if steam is coming out.

1.

Safely pull to the side of the road. Put the transmission in neutral (M/T) or Park (A/T), and set the parking brake. Turn off all accessories, and turn on the hazard warning indicators.

2.

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 the Engine Overheats

3.

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.

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 ). 262

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

Emergency 262

).

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.

If the Engine Overheats

6.

7.

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

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 pointer reaches the middle of the tempera- ture gauge, or lower, before check- ing 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.

252

8.

9.

Using gloves or a 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 (climate control to FULL AUTO at 90°F/32°C). 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.

Main MenuTable of Contentsst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.

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.

1.

2.

3.

4.

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

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.

159

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

204

).

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 262

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.

253

Main MenuTable of ContentsstMalfunction Indicator Lamp

If this 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.

If you have recently refueled your vehicle, the indicator coming on could be due to a loose or missing fuel fill cap. You will also see a ‘‘CHECK FUEL CAP’’ message on the information display. Tighten the cap until it clicks at least once. Tightening the cap will not turn the indicator off immediately; it can take several days of normal driving.

254

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 you keep driving with the malf unction indicator lamp on, you can damage your vehicle’s emissions controls and engine. Those repairs may not be covered by your vehicle’s warranties.

If your vehicle has an automatic transmission, the malfunction indicator lamp may also come on with the ‘‘D’’ indicator.

To check if they are set, turn the ignition switch to the ON (II) position, 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 five 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 Emissions Testing information (see page

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 thenexttimeyoustopataservice station (see page

215

).

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

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.

Brake System Indicator

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 262

Emergency ).

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

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

4.

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

5.

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

Main MenuTable of ContentsstFUSE PULLER

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.

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.

Fuses

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.

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).

Main Menust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 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.

Main MenuTable of Contentsst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 vehicle tires must conform to Federal Safety Requirements in addition to these grades.

−

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.

271

Main MenuTable of Contentsst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.

−

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.

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

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.

Main MenuTable of Contentsst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 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

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 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-
