2000 FORD MUSTANG warning light

BRAKES
Your service brakes are self-adjusting. Refer to the
scheduled maintenance guide for scheduled
maintenance.
Occasional brake noise is normal and often does not
indicate a performance concern with the vehicle's
brake system. In normal operation, automotive brake
systems may emit occasional or intermittent squeal
or groan noises when the brakes are applied. Such
noises are usually heard during the first few brake
applications in the morning; however, they may be
heard at any time while braking and can be
aggravated by environmental conditions such as
cold, heat, moisture, road dust, salt or mud. If a
ªmetal-to-metal,º ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking,
the brake linings may be worn-out and should be
inspected by a qualified service technician.
Anti-lock brake system (ABS)
On vehicles equipped with an anti-lock braking
system (ABS), a noise from the hydraulic pump
motor and pulsation in the pedal may be observed
during ABS braking events. Pedal pulsation coupled
with noise while braking under panic conditions or
on loose gravel, bumps, wet or snowy roads is
normal and indicates proper functioning of the
vehicle's anti-lock brake system. The ABS performs a
self-check after you start the engine and begin to
drive away. A brief mechanical noise may be heard
during this test. This is normal. If a malfunction is
found, the ABS warning light will come on. If the
vehicle has continuous vibration or shudder in the
steering wheel while braking, the vehicle should be
inspected by a qualified service technician.

The ABS operates by
detecting the onset of
wheel lockup during
brake applications and
compensates for this
tendency. The wheels
are prevented from
locking even when the brakes are firmly applied. The
accompanying illustration depicts the advantage of
an ABS equipped vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with
loss of front braking traction.
ABS warning lamp
ABS
TheABSwarning lamp in the instrument cluster
momentarily illuminates when the ignition is turned
to the ON position. If the light does not illuminate
momentarily at start up, remains on or continues to
flash, the ABS needs to be serviced.
With the ABS light on,
the anti-lock brake
system is disabled and
normal braking is still
effective unless the brake warning light also remains
illuminated with parking brake released. (If your
brake warning lamp illuminates, have your vehicle
serviced immediately.)
Using ABS
²In an emergency or when maximum efficiency
from the ABS is required, apply continuous force
on the brake. The ABS will be activated
immediately, thus allowing you to retain full
steering control of your vehicle and, providing
there is sufficient space, will enable you to avoid
obstacles and bring the vehicle to a controlled
stop.
²The Anti-Lock system does not decrease the time
necessary to apply the brakes or always reduce
P!

If it is necessary to use the above procedure to
move the gearshift lever, it is possible that a fuse
has blown or the vehicle's brakelamps are not
operating properly. Refer toFuses and relaysin the
Roadside emergencieschapter.
Do not drive your vehicle until you verify
that the brakelamps are working.
If your vehicle gets stuck in mud or snow it may be
rocked out by shifting from forward and reverse
gears, stopping between shifts, in a steady pattern.
Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at
normal operating temperature or damage to
the transmission may occur.
Do not rock the vehicle for more than a few
minutes or damage to the transmission and
tires may occur or the engine may overheat.
Always set the parking brake fully and make
sure the gearshift is latched in P (Park).
Turn off the ignition whenever you leave your
vehicle.
If the parking brake is fully released, but the
brake warning lamp remains illuminated, the
brakes may not be working properly. See your
dealer or a qualified service technician.

²Have 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 ªService Engine Soonº 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 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.
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.
