RWARNING 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. RWARNING On vehicles without original equipment floor covering or insulation, do not let passengers ride in your truck in a manner that allows contact between skin and the metal floor. If other than Ford or Motorcraft or Ford authorized remanufactured parts are used for maintenance, replacement, or for the service of components affecting emissions control, the owner should be assured that such parts are warranted by their manufacturer to be equivalent to genuine Ford Motor Company parts in performance and durability. Please consult your warranty information booklet for complete warranty information. Watch for fluid leaks, strange odors, smoke, loss of oil pressure, the charge warning light, the check engine light, or the temperature warning light. These sometimes indicate that the emission system is not working properly. Do not make any unauthorized changes to your vehicle or engine. Changes that cause more unburned fuel to reach the exhaust system can increase the temperature of the engine or exhaust system. 303
