FORD 2003 Mustang v.2 - Manual (Page 186)

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 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 diagnostics system.
If your “Check Engine/Service Engine Soon” light is
on, refer to the description in the Warning lights
and chimes section of the Instrument cluster
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 on-board diagnostics system
is reset to a “not ready for I/M test” condition. To
