AUTO-START-STOP (IF EQUIPPED)
The system helps reduce fuel consumptionby automatically stopping and restartingthe engine when your vehicle has stopped.The engine restarts automatically whenyou release the brake pedal.
In some situations, your vehicle may restartautomatically, for example:
•To maintain interior comfort.
•To recharge the battery.
Note:Power assist steering turns off whenthe engine is off.
Note:If your vehicle is flex fuel capable,Auto-Start-Stop will be inhibited for a shorttime after a refuel event while the systemis verifying the fuel type being used.
WARNING: Apply the parkingbrake, shift into park (P), switch theignition off and remove the key beforeyou leave your vehicle. Failure to followthis instruction could result in personalinjury or death.
WARNING: Apply the parkingbrake, shift into park (P), switch theignition off and remove the key beforeyou open the hood or have any serviceor repair work completed.

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 thevehicle from the engine and exhaustsystem heat and noise. On vehicles withno original equipment floor coveringinsulation, do not carry passengers in amanner that permits prolonged skincontact with the metal floor. Failure tofollow these instructions may result infire 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
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a shortperiod of engine operation and stays hotafter the engine is switched off.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust 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 293).
•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.
