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.

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 250).
•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 167).
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.

SelectShift Automatic™ Transmission (If
Equipped)
Your vehicle is equipped with a SelectShiftAutomatic transmission. The SelectShiftAutomatic transmission gives you the abilityto change gears up or down (without aclutch) as desired.
In order to prevent the engine from runningat too low an RPM, which may cause it tostall, SelectShift still automatically makessome downshifts if it has determined thatyou have not downshifted in time. AlthoughSelectShift makes some downshifts for you,it still allows you to downshift at any time aslong as the SelectShift determines thatdamage will not be caused to the enginefrom over-revving.
Note:Engine damage may occur if youmaintain excessive engine revving withoutshifting.
SelectShift does not automatically upshift,even if the engine is approaching the RPMlimit. It must be shifted manually by pressingthe + button. Notice should be taken of theshift indicator lamp, which alerts you whento shift to make sure you achieve the highestlevel or efficiency and fuel economy.
If equipped with the toggle on the gearshiftlever, press the + toggle switch on the sideof the gearshift lever to activate SelectShift.
•Press the (+) button to upshift.
•Press the (-) button to downshift.
If equipped with steering wheel paddles,pull the + paddle on the steering wheel toactivate SelectShift.
•Pull the right paddle (+) to upshift.
•Pull the left paddle (–) to downshift.
SelectShift in drive (D):
•Provides a temporary manual mode forperforming more demanding maneuverswhere extra control of gear selection isrequired (for example, when towing orovertaking). This mode will hold aselected gear for a temporary period oftime dependent on driver inputs (forexample, steering or accelerator pedalinput).

SelectShift in sport (S):
•Provides a permanent manual gearselection where full control of gearselection is required.
To exit SelectShift mode shift thetransmission into another gear (for example,drive [D]).
Upshift to the recommended shift speedsaccording to the following chart:
Upshifts when accelerating (recommended forbest fuel economy)
Shift from:
15 mph (24 km/h)1 - 2
25 mph (40 km/h)2 - 3
40 mph (64 km/h)3 - 4
45 mph (72 km/h)4 - 5
50 mph (80 km/h)5 - 6
The instrument cluster displays your currentlyselected gear. If a gear is requested but notavailable due to vehicle conditions (lowspeed, too high engine speed for requestedgear selection), the current gear will flashthree times.
Note:At full accelerator pedal travel, thetransmission automatically downshifts formaximum performance.
Note:In low traction conditions, you can pullaway in second gear using SelectShift. Toperform this operation, select drive (D) orsport (S) mode and press the + toggle (ifequipped) or pull the + paddle (if equipped)until 2 is displayed on the cluster. Yourvehicle is now ready to move in 2nd gear.
Brake-Shift Interlock
WARNING: Do not drive your vehicleuntil you verify that the brake lamps areworking.
WARNING: When doing thisprocedure, you need to take thetransmission out of park (P) which meansyour vehicle can roll freely. To avoidunwanted vehicle movement, always fullyapply the parking brake prior to doing thisprocedure. Use wheels chocks ifappropriate.
WARNING: If the parking brake isfully released, but the brake warning lampremains illuminated, the brakes may notbe working properly. Have your vehiclechecked as soon as possible.
Note:For some markets this feature will bedisabled.
Your vehicle is equipped with a brake-shiftinterlock feature that prevents moving thegearshift lever from park (P) when the ignitionis in the on position and the brake pedal isnot pressed.

If you cannot move the gearshift lever out ofpark (P) position with the ignition in the onposition and the brake pedal pressed, amalfunction may have occurred. It is possiblethat a fuse has blown or your vehicle’s brakelamps are not operating properly. See FuseSpecification Chart (page 262).
If the fuse is not blown and the brake lampsare working properly, the followingprocedure will allow you to move thegearshift lever from park (P):
1.Apply the parking brake, turn the ignitionoff and remove the key.
2. Remove the access plug on the side ofthe center console.
3. Apply the brake pedal. Using a suitabletool (for example, a screwdriver), pushthe brake-shift interlock override leverforward while pulling the gearshift leverout of park (P) and into neutral (N).
4. Install the access plug on side of thecenter console.
5. Apply the brake pedal, start the vehicle,and release the parking brake.
Automatic Transmission AdaptiveLearning
This feature may increase durability andprovide consistent shift feel over the life ofyour vehicle. A new vehicle or transmissionmay have firm shifts, soft shifts or both. Thisoperation is considered normal and does notaffect function or durability of thetransmission. Over time, the adaptivelearning process fully updates transmissionoperation.
If Your Vehicle Gets Stuck In Mud orSnow
Note:Do not rock the vehicle if the engineis not at normal operating temperature ordamage to the transmission may occur.
Note:Do not rock the vehicle for more thana minute or damage to the transmission andtires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow,you may rock it out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.

USING ALL-WHEEL DRIVE
All-wheel drive uses all four wheels to powerthe vehicle. This increases traction, enablingyou to drive over terrain and road conditionsthat a conventional two-wheel drive vehiclecannot. The AWD system is active all the timeand requires no input from the operator.
Note:Your AWD vehicle is not intended foroff-road use. The AWD feature gives yourvehicle some limited off-road capabilities inwhich driving surfaces are relatively level,obstruction-free and otherwise similar tonormal on-road driving conditions. Operatingyour vehicle under other than thoseconditions could subject the vehicle toexcessive stress which might result indamage which is not covered under yourwarranty.
Note:When an AWD system fault is present,the warning Check AWD displays in theinformation display. The AWD system is notfunctioning correctly and defaults tofront-wheel drive. When this warningdisplays, have your vehicle serviced at anauthorized dealer.
Note: The AWD OFF message may alsoappear in the information display if the AWDsystem overheats and defaults to front-wheeldrive. This may occur if the vehicle isoperated in extreme conditions withexcessive wheel slip, such as deep sand. To resume normal AWD function as soon aspossible, stop the vehicle in a safe locationand stop the engine for at least 10 minutes. After the engine has been restarted and theAWD system has adequately cooled, theAWD OFF message will turn off and normalAWD function returns. If the engine is notstopped, the AWD OFF message turns offwhen the system cools and normal AWDfunction returns.

Operating AWD Vehicles WithMismatched Tires
WARNING: Only use replacementtires and wheels that are the same size,load index, speed rating and type (such asP-metric versus LT-metric or all-seasonversus all-terrain) as those originallyprovided by Ford. The recommended tireand wheel size may be found on either theSafety Compliance Certification Label(affixed to either the door hinge pillar,door-latch post, or the door edge thatmeets the door-latch post, next to thedriver's seating position), or the Tire Labelwhich is located on the B-Pillar or edge ofthe driver's door. If this information is notfound on these labels, then you shouldcontact your authorized dealer as soon aspossible. Use of any tire or wheel notrecommended by Ford can affect thesafety and performance of your vehicle,which could result in an increased risk ofloss of vehicle control, vehicle rollover,personal injury and death.
WARNING: The use ofnon-recommended tires and wheels couldcause steering, suspension, axle, transfercase or power transfer unit failure. If youhave questions regarding tire replacement,contact your authorized dealer as soon aspossible.
Major dissimilar tire sizes between the frontand rear axles (for example, 17 inch lowprofile tires on the front axle and 22 inch highprofile tires on the rear axle) could cause theAWD system to stop functioning and defaultto front-wheel drive or damage the AWDsystem. However, the AWD system iscapable of tolerating any combination of newand worn tires of the same original tire size. For example, using 3 worn tread tires and 1new tread tire all of the same original tiresize, can be tolerated by the AWD system.
Driving In Special Conditions With All-Wheel Drive (AWD)
AWD vehicles are equipped for driving onsand, snow, mud and rough roads and haveoperating characteristics that are somewhatdifferent from conventional vehicles, both onand off the highway.
When driving at slow speeds in deep sandunder high outside temperatures, use a lowgear when possible. Lower gear operationwill maximize the engine and transmissioncooling capability.
Under severe operating conditions, the A/Cmay cycle on and off to protect overheatingof the engine.
Basic operating principles in specialconditions
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•Be extremely careful when driving onpavement made slippery by loose sand,water, gravel, snow or ice.
