EMISSION LAW
WARNING
Do not remove or alter the originalequipment floor covering orinsulation between it and the metalfloor of the vehicle. The floor covering andinsulation protect occupants of the vehiclefrom the engine and exhaust system heatand noise. On vehicles with no originalequipment floor covering insulation, do notcarry passengers in a manner that permitsprolonged skin contact with the metalfloor. Failure to follow these instructionsmay result in fire or personal injury.
U.S. federal laws and certain state lawsprohibit removing or rendering inoperativeemission control system components.Similar federal or provincial laws mayapply in Canada. We do not approve of anyvehicle modification without firstdetermining applicable laws.
Tampering with emissionscontrol systems includingrelated sensors or the DieselExhaust Fluid system can result in reducedengine power and the illumination of theservice engine soon light.
Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative byany person other than for purposes ofmaintenance.
•Repair or replacement of any device orelement of the design incorporated intoa new vehicle for the purpose of noisecontrol prior to its sale or delivery tothe ultimate purchaser or while it is inuse.
•The use of the vehicle after any personremoves or renders inoperative anydevice or element of the design.
The U.S. Environmental Protection Agencymay presume to constitute tampering asfollows:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturerspecifications.
If the engine does not start, runs rough,experiences a decrease in engineperformance, experiences excess fuelconsumption or produces excessiveexhaust smoke, check for the following:
•A plugged or disconnected air inletsystem hose.
•A plugged engine air filter element.
•Water in the fuel filter and waterseparator.
•A clogged fuel filter.
•Contaminated fuel.
•Air in the fuel system, due to looseconnections.
•An open or pinched sensor hose.
•Incorrect engine oil level.

•Incorrect fuel for climatic conditions.
•Incorrect engine oil viscosity forclimactic conditions.
Note:Some vehicles have a lifetime fuelfilter that is integrated with the fuel tank.Regular maintenance or replacement is notneeded.
Note:If these checks do not help youcorrect the concern, have your vehiclechecked as soon as possible.
Noise Emissions Warranty,Prohibited Tampering Acts andMaintenance
On January 1, 1978, Federal regulationbecame effective governing the noiseemission on trucks over 10,000 lb(4,536 kg) Gross Vehicle Weight Rating(GVWR). The preceding statementsconcerning prohibited tampering acts andmaintenance, and the noise warrantyfound in the Warranty Guide, areapplicable to complete chassis cabs over10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNINGS
Do not park, idle or drive your vehicleon dry grass or other dry groundcover. The emission system heats upthe engine compartment and exhaustsystem, creating the risk of fire.
The normal operating temperatureof the exhaust system is very high.Never work around or attempt torepair any part of the exhaust system untilit has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a short periodof engine operation and stays hot after theengine is switched off.
WARNINGS
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your vehicle inspectedimmediately. Do not drive if you smellexhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicableexhaust emission standards.
To make sure that the catalytic converterand other emission control componentscontinue to work properly:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 190).
•Use only the specified fuel listed.
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Resulting component damage maynot be covered by the vehicle Warranty.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.
If you use anything other than Ford,Motorcraft or Ford-authorized parts formaintenance replacements or for serviceof components affecting emission control,such non-Ford parts should be equivalentto genuine Ford Motor Company parts inperformance and durability.

Your vehicle may not pass the I/M test ifthe service engine soon indicator is on ornot working properly (bulb is burned out),or if the OBD-II system has determinedthat some of the emission control systemshave not been properly checked. In thiscase, the vehicle is not ready for I/Mtesting.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that thevehicle is not ready for I/M testing. Todetermine if the vehicle is ready for I/Mtesting, turn the ignition key to the onposition for 15 seconds without crankingthe engine. If the service engine soonindicator blinks eight times, it means thatthe vehicle is not ready for I/M testing; ifthe service engine soon indicator stays onsolid, it means that your vehicle is readyfor I/M testing.
The OBD-II system checks the emissioncontrol system during normal driving. Acomplete check may take several days.
If the vehicle is not ready for I/M testing,you can perform the following driving cycleconsisting of mixed city and highwaydriving:
1.15 minutes of steady driving on anexpressway or highway followed by 20minutes of stop-and-go driving with atleast four 30-second idle periods.
2.Allow your vehicle to sit for at leasteight hours with the ignition off. Then,start the vehicle and complete theabove driving cycle. The vehicle mustwarm up to its normal operatingtemperature. Once started, do not turnoff the vehicle until the above drivingcycle is complete.
If the vehicle is still not ready for I/Mtesting, you need to repeat the abovedriving cycle.

GENERAL INFORMATION
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out. Have thesystem checked by an authorized dealer.

Anti-Lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
If it illuminates when you aredriving, this indicates amalfunction. Your vehiclecontinues to have normal braking withoutthe anti-lock brake system function. Haveyour vehicle checked as soon as possible.
It also momentarily illuminates when youswitch the ignition on to confirm the lampis functional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the system checkedby an authorized dealer.

If it illuminates when your vehicle ismoving, make sure the parking brake isdisengaged. If the parking brake isdisengaged, this indicates low brake fluidlevel or a brake system fault. Have yourvehicle immediately checked.
It also momentarily illuminates when youswitch the ignition on to confirm the lampis functional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the system checkedby an authorized dealer.
