If you do not see steam or spray, leave the engine running, and check the high temperature indicator. If the high heat is due to overloading, the engine should start to cool down almost immediately. If it does, wait until the high temperature indicator goes off, then continue driving.
4.
If the high temperature indicator stays on, turn off 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 (manual) or Park (automatic), 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 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.
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 high temperature indicator goes off 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.

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.
139
If necessary, add oil to bring the level back to the full mark on the dipstick (see page
187
).
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

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.
2008 Fit 07/06/28 20:46:21 31SAA610 0236
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.
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.
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
Malfunction Indicator Lamp
these codes are set. If they are not set, the test cannot be completed.
If the battery in your vehicle 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.
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 an emissions test until the readiness codes are set. Emissions Testing Refer to more information (see page

Brake System Indicator
U.S.
Canada
Brake System Indicator (Red)
The brake system indicator (red) 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 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
238
Emergency ).
on page
If you must drive the vehicle a short distance in this condition, drive slowly and carefully.
If the brake system indicator (red)
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
195
).
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.

BLOWN
5.
Look for a blown wire inside the fuse. If it is blown, replace it with one of the spare fuses of the same 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 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.
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.
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 technician.
If the radio fuse is removed, the audio system will 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

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.
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.
246
2008 Fit 07/06/28 20:48:34 31SAA610 0252
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) Explanation 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

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 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
252
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- 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.

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.
Three Way Catalytic Converter
Keep the engine well maintained.
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.

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.
254
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.
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.
