It also illuminates momentarily 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 your authorized dealer.
Powertrain Malfunction/ReducedPower/Electronic Throttle Control
Illuminates when a powertrainor an 4WD fault has beendetected. Contact yourauthorized dealer as soon as possible.
Service Engine Soon
If the service engine soonindicator light stays illuminatedafter the engine is started, itindicates that the On-Board Diagnostics(OBD-II) system has detected amalfunction of the vehicle emissionscontrol system. Refer to On-BoardDiagnostics (OBD-II) in the Fuel andRefueling chapter for more informationabout having your vehicle serviced. SeeEmission Control System (page 196).
If the light is blinking, engine misfire isoccurring which could damage yourcatalytic converter. Drive in a moderatefashion (avoid heavy acceleration anddeceleration) and have your vehicleserviced immediately.
WARNING
Under engine misfire conditions,excessive exhaust temperaturescould damage the catalyticconverter, the fuel system, interior floorcoverings or other vehicle components,possibly causing a fire. Have your vehiclechecked as soon as possible.
The service engine soon indicator lightilluminates when the ignition is first turnedon prior to engine start to check the bulband to indicate whether the vehicle is readyfor Inspection/Maintenance (I/M) testing.
Normally, the service engine soon light willstay on until the engine is cranked, thenturn itself off if no malfunctions arepresent. However, if after 15 seconds theservice engine soon light blinks eight times,it means that the vehicle is not ready forI/M testing. See Emission ControlSystem (page 196).
Stability Control
Illuminates when the system isactive. If it remains illuminatedor does not illuminate when youswitch the ignition on, this indicates amalfunction. During a malfunction thesystem will switch off. Have the systemchecked by your authorized dealerimmediately. See Using StabilityControl (page 227).
Stability Control Off
Illuminates when you switch thesystem off. It will go out whenyou switch the system back onor when you switch the ignition off. SeeUsing Stability Control (page 227).
Transmission Tow/Haul (If Equipped)
Illuminates when the tow/haulfeature has been activated. If thelight flashes steadily, have thesystem serviced immediately, damage tothe transmission could occur.

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:
•Use only the specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while yourvehicle is moving, especially at highspeeds.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
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.
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 damagedexhaust system may allow exhaust toenter the vehicle. Have a damaged orimproperly operating exhaust systeminspected and repaired 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 vehiclesare not permitted to intentionally remove
an emission control device or prevent itfrom working. Information about yourvehicle’s emission system is on the VehicleEmission Control Information Decallocated on or near the engine. This decalalso lists engine displacement.
Please consult your warranty informationfor complete 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 theenvironment by making sure that yourvehicle continues to meet governmentemission standards. The OBD-II systemalso assists a service technician in properlyservicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate. Examples are:
1. Your vehicle has run out of fuel—theengine may misfire or run poorly.
2. Poor fuel quality or water in thefuel—the engine may misfire or runpoorly.
3. The fuel fill inlet may not have closedproperly. See Refueling (page 192).
4. Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank withgood quality fuel, properly closing the fuelfill inlet or letting the electrical system dryout. After three driving cycles without theseor any other temporary malfunctions

EMISSION CONTROL SYSTEM
- DIESEL
Oxidation Catalytic Converter andDiesel Particulate Filter System (If
Equipped)
WARNING
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 diesel oxidationcatalytic converter or the diesel particulatefilter. The diesel oxidation catalyticconverter and the diesel particulate filterheat up to very high temperatures afteronly a short period of engine operation andremain hot after you switch the engine off.
Your vehicle has a diesel particulate filter.The diesel particulate filter is an inline filterin the exhaust system that reduces carbonemissions by trapping exhaust particlesbefore they reach the tailpipe. The dieselparticulate filter looks similar to atraditional exhaust catalyst and is part ofthe exhaust system under your vehicle. Thefilter couples to a diesel oxidation catalystthat reduces the amount of harmfulexhaust emitted from the tailpipe. As sootgathers in the system, it begins to restrictthe filter. The system must periodicallyclean the soot that gathers inside the filter.This is carried out in two ways, passiveregeneration and active regeneration. Bothmethods occur automatically and requireno actions from the driver. During eitherone of these regeneration methods,although you may notice a change inexhaust tone. At certain times, theinformation display shows variousmessages related to the diesel particulatefilter. See Information Messages (page128).
Diesel Particulate Filter Maintenance
You must properly maintain your vehicle'sdiesel particulate filter in order for it tofunction properly.
Do not disregard maintenance messagesthat appear in the information display.Failure to follow the instructions of aninformation message may degrade vehicleperformance and could lead to enginedamage that may not be covered by thevehicle Warranty.
Failure to perform active or operatorcommanded regeneration when instructedcould result in a clogged diesel particulatefilter. If the diesel particulate filter fillsbeyond the regeneration threshold, yourvehicle disables the ability for active andoperator commanded regeneration. Thiscould result in irreversible damage to thediesel particulate filter requiringreplacement that may not be covered bythe vehicle Warranty.
Passive Regeneration
In passive regeneration, the exhaustsystem temperature and constituentsautomatically clean the filter by oxidizingthe soot. Cleaning automatically occursduring normal vehicle operating conditionsdue to driving patterns.
Active Regeneration
Once the diesel particulate filter is full ofexhaust particles, the engine controlmodule commands the exhaust system toclean the filter through active regeneration.Active regeneration requires the enginecomputer to raise the exhaust temperatureto eliminate the particles. During cleaning,the particles convert to harmless gasses.Once cleaned the diesel particulate filtercontinues trapping exhaust particles.

CLEANING THE EXHAUST -
6.7L DIESEL
WARNINGS
Failure to maintain the functionalholes, in the tailpipe section of theexhaust, clean and free of debris orforeign material may result in the holesbecoming blocked or plugged. Do notmodify or remove the tail-pipe section.Blocked or plugged holes orremoval/modification of the system couldresult in elevated exhaust gastemperatures which may result invehicle/property damage or personalinjury.
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 diesel oxidationcatalytic converter and/or the dieselparticulate filter (DPF). The dieseloxidation catalytic converter and/or theDPF heats up to a high temperature afteronly a short period of engine operation andcan stay hot even after the engine is turnedoff. Failure to follow these instructions mayresult in personal injury.
The visible holes in the exhaust tip and theholes under the shield just inboard of theright rear tire(s) are functional. The holesneed to be kept clear of mud/debris orforeign material to maintain properfunction of the exhaust system. Clean andremove debris or foreign material if presentas needed. Spraying with a hose duringregular washing of vehicle should helpkeep holes clean and clear of debris orforeign material.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmentalfallout can result in windshield and wiperblade contamination. Dirty windshield andwipers will result in poor windshield wiperoperation. Keep the windshield and wiperblades clean to maintain windshield wiperperformance.
