2000 FORD MUSTANG headlamp

Important safety precautions
A computer system controls the engine's idle
revolutions per minute (RPM). When the engine
starts, the idle RPM runs faster to warm the engine.
If the engine idle speed does not slow down
automatically, have the vehicle checked. Do not
allow the vehicle to idle for more than 10 minutes at
high engine RPM.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled
their safety belts. For more information on safety
belts and their proper usage, refer to theSeating
and safety restraintschapter.
2. Make sure the headlamps and vehicle accessories
are off.
If starting a vehicle with an automatic transmission:
²Make sure the
parking brake is set.
²Make sure the gearshift is in P (Park).
If starting a vehicle with a manual transmission:
²Make sure the parking brake is set.
²Push the clutch
pedal to the floor.

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.
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.

To install the new bulb:
Handle a halogen headlamp bulb carefully
and keep out of children's reach. Grasp the
bulb only by its plastic base and do not touch the
glass. The oil from your hand could cause the bulb
to break the next time the headlamps are
operated.
1. With the flat side of the new bulb's plastic base
facing upward, insert the glass end of the bulb into
the lamp assembly. You may need to turn the bulb
left or right to align the grooves in the plastic base
with the tabs in the lamp assembly. When the
grooves are aligned, push the bulb into the lamp
assembly until the plastic base contacts the rear of
the lamp assembly.
2. Install the bulb retaining ring over the plastic base
until it contacts the rear of the socket by rotating
clockwise until you feel a ªstop.º
3. Connect the electrical connector into the plastic
base until it snaps, locking it into position.
4. Install the headlamp on vehicle by aligning the
lamp with the rear snap retainers, push to seat and
secure with two retainer pins.
5. Turn the headlamps on and make sure they work
properly. If the headlamp was correctly aligned
before you changed the bulb, you should not need to
align it again.
