When you turn the ignition switch to the START (III) position, you do not hear the normal noise of the engine trying to start. You may hear a clicking sound, a series of clicks, or nothing at all. Check these things:
Check the transmission interlock. The transmission must be in Park or neutral or the starter will not operate.
Turn the ignition switch to the ON (II) position. Turn on the headlights, and check their brightness. If the headlights are very dim or do not come on at all, the battery is discharged. See Jump Starting
on page
278
Turn the ignition switch to the START (III) position. If the headlights do not dim, check the condition of the fuses. If the fuses are OK, there is probably something wrong with the electrical circuit for the ignition switch or starter motor. You will need a qualified technician to determine the problem. See Emergency Towing
on page
285
If the headlights dim noticeably or go out when you try to start the engine, either the battery is discharged or the connections are corroded. Check the condition of the battery and terminal connections (see page can then try jump starting the vehicle from a booster battery (see page
). You

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.
1.
To jump start your vehicle: 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.

Jump Starting
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.
5.
6.
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.

Connect the second jumper cable to the negative ( ) terminal on the booster battery. Connect the other end to the grounding strap as shown. Do not connect this jumper cable to any other part of the engine.
2008 Pilot 07/05/09 11:51:21 31S9V650 0285
If the Engine Overheats
The pointer of your vehicle’s temperature gauge should stay in the midrange under most conditions. 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.
280
Steam and spray from an overheated engine can seriously scald you.
Do not open the hood if steam is coming out.
1.
2.
Safely pull to the side of the road. Put the transmission in Park, and set the parking brake. Turn off all accessories, and turn on the hazard warning lights.
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.
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
).
285
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
192
below the MIN mark.
2008 Pilot 07/05/09 11:51:26 31S9V650 0286
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 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.
10.
11.
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 interior temperature 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.
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
285
).
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.
282
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.
191
If necessary, add oil to bring the level back to the full mark on the dipstick (see page
245
).
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 ).
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.
2008 Pilot 07/05/09 11:51:42 31S9V650 0288
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, 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 turn off as you continue driving, have your vehicle checked by your 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 the engine. Those repairs may not be covered by your vehicle’s warranties.
If the malfunction indicator lamp comes on along with the ‘‘D’’ indicator, there is a problem in the automatic transmission control system.
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.
Malfunction Indicator Lamp
If the battery in your vehicle has been disconnected or gone dead, these codes may be erased. It takes 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 5 times, the readiness
codes are not set. If possible, do not
take your vehicle for a state
emissions test until the readiness
Emissions
codes are set. Refer to
Testing
for more information (see
305

2008 Pilot 07/05/09 11:51:49 31S9V650 0289
Brake System Indicator
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.
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.
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
285
Emergency ).
on page
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 the next time you stop at a service station (see page
252
).
If the fluid level is low, take your vehicle to a dealer, and have the brake system inspected for leaks or worn brake pads.

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.
The only way you can safely tow your vehicle is with flat-bed equipment. The operator will load your vehicle on the back of a truck. Any other method of towing will damage the drive system. When you contact the towing agency, inform them a flat-bed is required.

Checking and Replacing Fuses
If something electrical in your
vehicle stops working, the first thing
you should check for is a blown fuse.
Determine from the chart on pages
, or the diagram on the
289
fuse box lid, which fuse or 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.

1.
Turn the ignition switch to the LOCK (0) position. Make sure the headlights and all other accessories are off.
2.

Check each of the large fuses in the primary under-hood fuse box by looking through the top at the wire inside. Remove the screws with a Phillips-head screwdriver.
4.
Check the smaller fuses in the under-hood fuse box and all the fuses in the interior fuse boxes by pulling out each fuse with the fuse puller.
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.
The fuse puller is in the primary under-hood fuse box.

Fuses
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.
288
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.
If the driver’s power window fuse is removed, the AUTO function of the driver’s window may be disabled. You should reset the AUTO feature, (see page
95
).
ExceptforLXmodels 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 digit code (see page
141
).
Trailer Fuses If a trailer light is burned out, check if these fuses are blown when you replace the light bulbs:
Primary under-hood fuse box
fuses 5, 7, and 24
Interior driver’s side fuse box: 10
Interior passenger’s side fuse box:
10
If those fuses are OK, but the trailer lights still do not work, there are two blown 7.5 amp fuses in the trailer hitch wiring. To access the 7.5 amp fuses: 1.
Open the tailgate and remove the cargo floor lid. Pull out the bottom of the tailgate rubber seal. Remove rear trim panel by pulling up on the inside edge of the rear trim panel, and unhooking the four clips and tabs. After replacing fuses, and reinstall the rear trim panel in the reverse order of removal.

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.
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.

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
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
and/or
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.

Emissions Controls
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.

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.
