1999 FORD MUSTANG check engine

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,
ªService Engine Soonº 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 ªWarranty Guideº 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 ªCheck Engine/Service Engine Soonº light is
on, refer to the description in theWarning Lights
and Chimessection of theInstrumentation
chapter. Your vehicle may not pass the I/M test with
the ªCheck Engine/Service Engine Soonº light on.
Maintenance and care
169

If the vehicle's powertrain system or its battery has
just been serviced, the on-board diagnostics system
is reset to a ªnot ready for I/M testº condition. To
ready the on-board diagnostics system for I/M
testing, a minimum of 30 minutes of city and
highway driving is necessary as described below:
²First, at least 10 minutes of driving on an
expressway or highway.
²Next, 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.
EXTERIOR BULBS
Replacing exterior bulbs
Check the operation of the following lamps
frequently:
²Headlamps
²Tail lamps
²Brakelamps
²High-mount brakelamp
²Turn signals
²Backup lamps
²License plate lamp
Do not remove lamp bulbs unless they will be
replaced immediately. If a bulb is removed for an
extended period of time, contaminants may enter
the lamp housings and affect performance.

required or the axle assembly has been submerged
in water. The axle lubricant should be changed any
time the rear axle has been submerged in water. Fill
6 mm to 14 mm (1/4 inch to 9/16 inch) below
