RUNNING OUT OF FUEL
Running out of fuel can cause damage notcovered by the vehicle Warranty.
If your vehicle runs out of fuel:
•Add a minimum of 1.3 gal (5 L) of fuel torestart the engine.
•You may need to switch the ignition fromoff to on several times after refueling toallow the fuel system to pump the fuelfrom the tank to the engine. Whenrestarting, cranking time takes a fewseconds longer than normal.
Note:If your vehicle is on a steep slope,more fuel may be required.
Filling a Portable Fuel Container
WARNING: Flow of fuel through afuel pump nozzle can produce staticelectricity. This can cause a fire if you arefilling an ungrounded fuel container.
Use the following guidelines to avoidelectrostatic charge build-up, which canproduce a spark, when filling an ungroundedfuel container:
•Only use an approved fuel container totransfer fuel to your vehicle. Place thecontainer on the ground when filling it.
•Do not fill a fuel container when it isinside your vehicle (including the cargoarea).
•Keep the fuel pump nozzle in contactwith the fuel container when filling it.
•Do not use a device that holds the fuelpump nozzle lever in the fill position.
Adding Fuel From a Portable FuelContainer
WARNING: Do not insert the nozzleof a fuel container or an aftermarket funnelinto the fuel filler neck. This may damagethe fuel system filler neck or its seal andcause fuel to run onto the ground.
WARNING: Do not try to pry open orpush open the capless fuel system withforeign objects. This could damage the fuelsystem and its seal and cause injury to youor others.
WARNING: Do not dispose of fuel inthe household refuse or the public sewagesystem. Use an authorized waste disposalfacility.
When refueling the vehicle fuel tank from afuel container, use the fuel filler funnelincluded with your vehicle. See Fuel FillerFunnel Location (page 200).

FUEL CONSUMPTION
Advertised Capacity
The advertised capacity is the maximumamount of fuel that you can add to the fueltank after running out of fuel. Included in theadvertised capacity is an empty reserve. Theempty reserve is an unspecified amount offuel that remains in the fuel tank when thefuel gauge indicates empty.
Note:The amount of fuel in the emptyreserve varies and should not be relied uponto increase driving range.
Fuel Economy
Your vehicle calculates fuel economy figuresthrough the trip computer average fuelfunction.
The first 1,000 mi (1,500 km) of driving is thebreak-in period of the engine. A moreaccurate measurement is obtained after2,000 mi (3,000 km).
Impacting Fuel Economy
•Incorrect tire inflation pressures.
•Fully loading your vehicle.
•Carrying unnecessary weight.
•Adding certain accessories to yourvehicle such as bug deflectors, rollbarsor light bars, running boards and skiracks.
•Using fuel blended with alcohol. SeeFuel Quality (page 200).
•Fuel economy may decrease with lowertemperatures.
•Fuel economy may decrease whendriving short distances.
•You may get better fuel economy whendriving on flat terrain than when drivingon hilly terrain.

EMISSION LAW
WARNING: Do not remove or alterthe original equipment floor covering orinsulation between it and the metal floorof 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 metal floor.Failure to follow these instructions mayresult in fire or personal injury.
U.S. federal laws and certain state lawsprohibit removing or rendering inoperativeemission control system components. Similarfederal or provincial laws may apply inCanada. We do not approve of any vehiclemodification without first determiningapplicable laws.
Tampering with emissions controlsystems including related sensorsor the Diesel Exhaust Fluid systemcan result in reduced engine power and theillumination of the service engine soon light.
Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative by anyperson 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 to theultimate purchaser or while it is in use.
•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 excessive exhaustsmoke, 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 for climacticconditions.
Note:Some vehicles have a lifetime fuel filterthat is integrated with the fuel tank. Regularmaintenance or replacement is not needed.
Note:If these checks do not help you correctthe concern, have your vehicle checked assoon as possible.
Noise Emissions Warranty, ProhibitedTampering Acts and Maintenance
On January 1, 1978, Federal regulationbecame effective governing the noiseemission on trucks over 10,000 lb (4,536 kg)Gross Vehicle Weight Rating (GVWR). Thepreceding statements concerning prohibitedtampering acts and maintenance, and thenoise warranty found in the Warranty Guide,are applicable to complete chassis cabs over10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNING: Do not park, idle or driveyour vehicle on dry grass or other dryground cover. The emission system heatsup the engine compartment and exhaustsystem, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system is veryhigh. 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.
WARNING: Exhaust leaks may resultin entry of harmful and potentially lethalfumes into 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 applicable exhaustemission standards.
To make sure that the catalytic converter andother emission control components continueto 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 328).
•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.

Engine Emission Control

The scheduled maintenance items listed inscheduled maintenance information areessential to the life and performance of yourvehicle and to its emissions system.
If you use anything other than Lincoln,Motorcraft or Lincoln-authorized parts formaintenance replacements or for service ofcomponents affecting emission control, suchnon-Lincoln parts should be equivalent togenuine Lincoln Motor Company parts inperformance and durability.
Illumination of the service engine soonindicator, charging system warning light orthe temperature warning light, fluid leaks,strange odors, smoke or loss of enginepower could indicate that the emissioncontrol system is not working properly.
An improperly operating or damaged exhaustsystem may allow exhaust to enter thevehicle. Have a damaged or improperlyoperating exhaust system inspected andrepaired immediately.
Do not make any unauthorized changes toyour vehicle or engine. By law, vehicleowners and anyone who manufactures,repairs, services, sells, leases, tradesvehicles, or supervises a fleet of vehicles arenot permitted to intentionally remove anemission control device or prevent it fromworking. Information about your vehicle’semission system is on the Vehicle EmissionControl Information Decal located on or nearthe engine. This decal also lists enginedisplacement.
Please consult your warranty information forcomplete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects the environmentby making sure that your vehicle continuesto meet government emission standards. TheOBD-II system also assists a servicetechnician in properly servicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected a malfunction.Temporary malfunctions may cause theservice engine soon indicator to illuminate.Examples are:
1. Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in the fuel—theengine may misfire or run poorly.
3. The fuel fill inlet may not have closedproperly. See Refueling (page 202).
4. Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank with goodquality fuel, properly closing the fuel fill inletor letting the electrical system dry out. Afterthree driving cycles without these or anyother temporary malfunctions present, theservice engine soon indicator should stay offthe next time you start the engine. A drivingcycle consists of a cold engine startupfollowed by mixed city and highway driving.No additional vehicle service is required.

Engine Emission Control

If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II may nothave symptoms that are apparent, continueddriving with the service engine soon indicatoron can result in increased emissions, lowerfuel economy, reduced engine andtransmission smoothness and lead to morecostly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programs toinspect the emission control equipment onyour vehicle. Failure to pass this inspectioncould prevent you from getting a vehicleregistration.
If the service engine soon indicatoris on or the bulb does not work,your vehicle may need service.See On-Board Diagnostics.
Your vehicle may not pass the I/M test if theservice engine soon indicator is on or notworking properly (bulb is burned out), or ifthe OBD-II system has determined that someof the emission control systems have notbeen properly checked. In this case, thevehicle is not ready for I/M testing.
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 the vehicleis not ready for I/M testing. To determine ifthe vehicle is ready for I/M testing, turn theignition key to the on position for 15 secondswithout cranking the engine. If the serviceengine soon indicator blinks eight times, itmeans that the vehicle is not ready for I/Mtesting; if the service engine soon indicatorstays on solid, it means that your vehicle isready for 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, youcan perform the following driving cycleconsisting of mixed city and highway driving:
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 least eighthours with the ignition off. Then, start thevehicle and complete the above drivingcycle. The vehicle must warm up to itsnormal operating temperature. Oncestarted, do not turn off the vehicle untilthe above driving cycle is complete.
If the vehicle is still not ready for I/M testing,you need to repeat the above driving cycle.
