•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 dry groundcover. The emission system heats up theengine compartment and exhaust system,creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system is veryhigh. Never work around or attempt to repairany part of the exhaust system until it hascooled. Use special care when workingaround the catalytic converter. The catalyticconverter heats up to a very hightemperature after only a short period ofengine 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 your vehicle,have your vehicle inspected immediately. Donot drive if you smell exhaust 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 264).
•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.

If you use oil and fluids that do not meet thedefined specification and viscosity grade,this may lead to:
•Component damage, which the vehiclewarranty does not cover.
•Longer engine cranking periods.
•Increased emission levels.
•Reduced engine performance.
•Reduced fuel economy.
•Degraded brake performance.
We recommend Motorcraft motor oil for yourvehicle. If Motorcraft oil is not available, usemotor oils of the recommended viscositygrade that meet API SN requirements anddisplay the API Certification Mark for gasolineengines. Do not use oil labeled with API SNservice category unless the label alsodisplays the API certification mark.

An oil that displays this symbol conforms tocurrent engine, emission system and fueleconomy performance standards of ILSAC.
Do not use supplemental engine oil additivesbecause they are unnecessary and couldlead to engine damage not covered by yourvehicle warranty.
Note:We recommend using DOT 4 LowViscosity (LV) High Performance Brake Fluidor equivalent meeting WSS-M6C65-A2. Useof any fluid other than the recommendedfluid may cause degraded brakeperformance and not meet our performancestandards. Keep brake fluid clean and dry.Contamination with dirt, water, petroleumproducts or other materials may result inbrake system damage and possible failure.
Note: Automatic transmissions that requireMERCON® LV transmission fluid should onlyuse MERCON® LV transmission fluid. Theuse of any other fluid may causetransmission damage.
