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 ). 370


on page


6.


If you don’t find an obvious leak, check the coolant level in the radiator reserve tank (see page ). Add coolant if the level is 269
below the MIN mark.


360


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.


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.


9.


Start the engine, and set the temperature control dial to maximum heat. 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.


11.


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 370


).


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.


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 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.


267


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


312


).


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 370


Emergency Towing ).


on page


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.


361


2009 Civic Coupe Table Of ContentsMain Menu 08/07/08 11:33:30 31SVA630 0367 


Malfunction Indicator Lamp


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. Tightening the cap will not turn the indicator off immediately; it can take several days of normal driving.


362


If the indicator comes on repeatedly, even though it may turn off as you continue driving, have your vehicle checked by the 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


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 may be erased. It can take several 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


for 388


).

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


322


).


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 and the VSA system indicator (if equipped) 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 370


Emergency ).

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

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.


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.

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:



Flat-bedEquipment loads your vehicle on the back of a truck. transport your vehicle.


This is the best way to


The operator



The tow


Wheel-liftEquipment truck uses two pivoting arms that go under the front tires and lift them off the ground. The rear tires remain on the ground. way to tow your vehicle.


This is an acceptable


370


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 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.


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).


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.


2009 Civic Coupe Table Of ContentsMain Menu 08/07/08 11:34:37 31SVA630 0376 


Emergency Towing


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.


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 located 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.


To access the VIN in the engine compartment, slide the lid on the back of the engine compartment. Make sure to close the lid before closing the hood.

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.


379


2009 Civic Coupe Table Of ContentsMain Menu 08/07/08 11:36:03 31SVA630 0385 


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

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 three or four systems: PGM-FI, ignition timing control, exhaust gas recirculation (DX, Canadian DX-G, LX, EX and EX-L), 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 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
