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 lights.
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 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.

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.
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 pointer 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.

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.

276
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.
188
If necessary, add oil to bring the level back to the full mark on the dipstick (see page
232
).
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
285
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 MenuTable of Contentsst05/07/28 14:02:46 31SDP630 0280
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.
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 (see page ). Tightening the cap will not turn the indicator off immediately; it takes several days of normal driving.
186
Malfunction Indicator Lamp
If the indicator comes on repeatedly, even though it may turn off as you continue driving, have the vehicle checked by the 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.
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 with the ‘‘D’’ indicator.
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.
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 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 Emissions Testing information (see page
State for more ).

If you must drive the vehicle a short distance in this condition, drive slowly and carefully.
If the ABS indicator and the VSA system indicator come 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
on page ).

Brake System Indicator
U.S.
Canada
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

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

Look for a blown wire inside the fuse. If it is blown, replace it with oneofthesparefusesofthesame rating or lower.
282
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 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 mechanic.
If the driver’s power window fuse is
removed, the AUTO function of the
driver’s window will be disabled. To
reset the AUTO function, see page

If the radio fuse is removed, the audio system will disable itself. Thenexttimeyouturnonthe radio you will see ‘‘CODE/COdE’’ in the frequency display. Use the preset bars to enter the code (see page

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.

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.
294
−
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.

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. Grade C corresponds to a level of performance that 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 overloaded. Excessive speed, underinflation, 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. Controlling the production of NOx, CO, and HC is important to the environment. Under certain conditions of sunlight and climate, NOx and HC react to form photochemical ‘‘smog.’’ Carbon monoxide does not contribute 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.

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 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
