Introduction Warning symbols on your vehicle When you see this symbol, it is imperative that you consult the relevant section of this guide before touching or attempting adjustment of any kind. Protecting the environment We must all play our part in protecting the environment. Correct vehicle usage and the authorized disposal of waste, cleaning and lubrication materials are significant steps towards this aim. Information in this respect is highlighted in this guide with the tree symbol. BREAKING-IN YOUR VEHICLE Your vehicle does not need an extensive break-in. Try not to drive continuously at the same speed for the first 1,000 miles (1,600 km) of new vehicle operation. Vary your speed frequently in order to give the moving parts a chance to break in. Drive your new vehicle at least 500 miles (800 km) before towing a trailer. Additionally, during the first 500 miles (800 km) that you tow a trailer, do not drive over 50 mph (80 km/h) and do not make starts at full throttle. This style of driving will help the engine and other parts of your vehicle wear-in at the heavier loads. Do not add friction modifier compounds or special break-in oils during the first few thousand miles (kilometers) of operation, since these additives may prevent piston ring seating. See Engine oil in the Maintenance and Specifications chapter for more information on oil usage. SPECIAL NOTICES Emission warranty The New Vehicle Limited Warranty includes Bumper-to-Bumper Coverage, Safety Restraint Coverage, Corrosion Coverage, and 6.0L Power Stroke Diesel Engine Coverage.

For a detailed description of what is covered and what is not covered, refer to the Warranty Guide that is provided to you along with your Owner's Guide. 5 2004 F150 (f12) Owners Guide (post-2002-fmt) USA English (fus)
