2003 FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS warning

•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 “Service Engine Soon” 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.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult yourWarranty Guidefor complete emission warranty
information.
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If your “Check Engine/Service Engine
Soon” light is on, refer to the description in theWarning lights and
chimessection of theInstrument clusterchapter. Your vehicle may not
pass the I/M test with the “Check Engine/Service Engine Soon” light on.

SERVICING YOUR TIRES
Tire inflation information
This vehicle is equipped with a tire that is an all-steel radial. All-steel
radial tires utilize steel cords in the sidewalls, and also require increased
inflation pressures of up to 95 psi (refer to the Certification Label for
recommended tire pressure). As such, they cannot be treated like normal
light truck tires. Tire service, including adjusting tire pressure, must be
performed by personnel trained, supervised and equipped according to
Federal Occupational Safety and Health Administration (OSHA)
regulations. For example, during any procedure involving tire inflation,
the technician or individual must utilize a remote inflation device, and
insure that all persons are clear of the trajectory area.
WARNINGAn inflated tire and rim can be very dangerous if
improperly used, serviced or maintained. To avoid serious injury,
never attempt to re-inflate a tire which has been run flat or seriously
under-inflated without first removing the tire from the wheel assembly for
inspection. Do not attempt to add air to tires or replace tires or wheels
without first taking precautions to protect persons and property.
Tire rotation
Because your vehicle’s tires perform different jobs, they often wear
differently. To make sure your tires wear evenly and last longer, rotate
them as indicated in the scheduled maintenance guide. If you notice that
the tires wear unevenly, have them checked.
Your front tires should be rotated from side to side. If the spare tire is
used in the rotation, the pattern should be; left front to right front; right
front to the spare and the spare to left front.
Do not rotate the dual tires.
