Ford 1999 F-150 Automobile User Manual


 
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 charging system warning light, Check Engine
indicator light or the temperature warning light, fluid leaks, strange
odors, smoke or loss of oil pressure, 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 your “Warranty Guide” for 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 diagnostic (OBD-II) system. If your “Check Engine/Service Engine
Soon” light is on, refer to the description in the Warning Lights and
Chimes section of the Instrumentation chapter. Your vehicle may not pass
the I/M test with the “Check Engine/Service Engine Soon” light on.
If the vehicle’s powertrain system or its battery has just been serviced,
the OBD-II system is reset to a “not ready for I/M test” condition. To
ready the OBD-II system for I/M testing, a minimum of 30 minutes of city
and highway driving is necessary as described below:
First, at least 10 minutes of driving on an expressway or highway.
Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
