To make sure that the catalytic converter and other emission control components continue to work properly: • Use only the specified fuel listed. • Avoid running out of fuel. • Do not turn off the ignition while your vehicle is moving, especially at high speeds. • Have the items listed in your scheduled maintenance guide performed according to the specified schedule. The scheduled maintenance items listed in the scheduled maintenance guide are essential to the life and performance of your vehicle and to its emissions system. If other than Ford, Motorcraft or Ford-authorized parts are used 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. Do not park, idle, or drive your vehicle in dry grass or other dry ground cover. The emission system heats up the engine compartment and exhaust system, which can start a fire. Illumination of the "Check Engine" light, charging system warning light or the temperature warning light, fluid leaks, strange odors, smoke or loss of engine power, could indicate that the emission control system is not working properly. 256
