•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.

Motor oils of the recommended viscositygrade that display the API CertificationMark for gasoline engines are alsoacceptable. Do not use oil labeled withAPI SN service category unless the labelalso displays the API certification mark.
Note:Automatic transmissions that requireMERCON® LV transmission fluid shouldonly use MERCON® LV transmission fluid.
An oil that displays this symbol conformsto current engine, emission system andfuel economy performance standards ofthe International Lubricants SpecificationAdvisory Committee (ILSAC).
Note:Do not use more than 1.1 qt (1 L) ofthe alternative engine oil betweenscheduled service intervals.
Using oil and fluids that do not meet thedefined specification and viscosity grademay lead to:
•Component damage which may not becovered by the vehicle Warranty.
•Longer engine cranking periods.
•Increased emission levels.
•Reduced engine performance.
•Reduced fuel economy.
•Reduced brake performance.
Do not use supplemental engine oiladditives because they are unnecessaryand could lead to engine damage that maynot be covered by the vehicle Warranty.
Alternative Engine Oil forExtremely Cold Climates
To improve engine cold start performance,we recommend that you use the followingalternative engine oil where the ambienttemperature reaches -22°F (-30°C) orbelow.
