Engine Emission Control

• Incorrect fuel for climatic conditions. • Incorrect engine oil viscosity for climactic conditions. Note: Some vehicles have a lifetime fuel filter that is integrated with the fuel tank. Regular maintenance or replacement is not needed. Note: If these checks do not help you correct the concern, have your vehicle checked as soon as possible. Noise EmissionsWarranty, Prohibited Tampering Acts and Maintenance On January 1, 1978, Federal regulation became effective governing the noise emission on trucks over 10,000 lb (4,536 kg) Gross Vehicle Weight Rating (GVWR). The preceding statements concerning prohibited tampering acts and maintenance, and the noise warranty found in the Warranty Guide, are applicable to complete chassis cabs over 10,000 lb (4,536 kg) GVWR. CATALYTIC CONVERTER WARNINGS Do not park, idle or drive your vehicle on dry grass or other dry ground cover. The emission systemheats up the engine compartment and exhaust system, creating the risk of fire. The normal operating temperature of the exhaust system is very high. Never work around or attempt to repair any part of the exhaust system until it has cooled. Use special care when working around the catalytic converter. The catalytic converter heats up to a very high temperature after only a short period of engine operation and stays hot after the engine is switched off.

WARNINGS Exhaust leaks may result in entry of harmful and potentially lethal fumes into the passenger compartment. If you smell exhaust fumes inside your vehicle, have your vehicle inspected immediately. Do not drive if you smell exhaust fumes. Your vehicle has various emission control components and a catalytic converter that enables it to comply with applicable exhaust emission standards. To make sure that the catalytic converter and other emission control components continue to work properly: • Do not crank the engine for more than 10 seconds at a time. • Do not run the enginewith a spark plug lead disconnected. • Do not push-start or tow-start your vehicle. Use booster cables. See Jump Starting the Vehicle (page 292). • Use only the specified fuel listed. • Donot switch the ignitionoffwhen your vehicle is moving. • Avoid running out of fuel. • Have the items listed in scheduled maintenance information performed according to the specified schedule. Note: Resulting component damage may not be covered by the vehicle Warranty. The scheduled maintenance items listed in scheduledmaintenance informationare essential to the life and performance of your vehicle and to its emissions system. If you use anything other than Ford, Motorcraft or Ford-authorized parts for maintenance replacements or for service of components affecting emission control, such non-Ford parts should be equivalent to genuine Ford Motor Company parts in performance and durability.
