Radio frequency information
The Federal Communications Commission (FCC) and the Canadian Radio
and Telecommunications Commission(CRTC) establish the frequencies
AM and FM stations may use for their broadcasts. Allowable frequencies
are:
AM 530, 540±1600, 1610 kHz
FM 87.7, 87.9±107.7, 107.9 MHz
Not all frequencies are used in a given area.
Radio reception factors
Three factors can affect radio reception:
²Distance/strength.The further an FM signal travels, the weaker it is.
The listenable range of the average FM station is approximately 40 km
(24 miles). This range can be affected by ªsignal modulation.º Signal
modulation is a process radio stations use to increase their
strength/volume relative to other stations.
²Terrain.Hills, mountains and tall buildings between your vehicle's
antenna and the radio station signal can cause FM reception problems.
Static can be caused on AM stations by power lines, electric fences,
traffic lights and thunderstorms. Moving away from an interfering
structure (out of its ªshadowº) returns your reception to normal.
²Station overload.Weak signals are sometimes captured by stronger
signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.
The audio system automatically switches to single channel reception if it
will improve the reception of a station normally received in stereo.
Audio system warranties and service
Refer to the ªWarranty Guideº for audio system warranty information.
If service is necessary, see your dealer or a qualified technician.

(ACC) position. The
THEFTlight in
the instrument cluster will flash
every two seconds when the vehicle
is armed.
Automatic disarming
Switching the ignition to the 3 (ON) position with acoded keydisarms
the vehicle. The
THEFTlight will illuminate for three seconds and then
go out. If the
THEFTlight stays on for an extended period of time or
flashes rapidly, have the system serviced by your dealership or a
qualified technician.

All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag SRS is
provided.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
National Highway Traffic Safety Administration (NHTSA)
recommends a minimum distance of at least 25 cm (10 inches)
between an occupant's chest and the driver air bag module.
Never place your arm over the air bag module as a deploying air
bag can result in serious arm fractures or other injuries.
Steps you can take to properly position yourself away from the air bag:
²Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
²Recline the seat slightly (one or two degrees) from the upright
position.
Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.
Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln Mercury dealer.
Modifications to the front end of the vehicle, including frame,
bumper, front end body structure and non-Ford tow hooks may
effect the performance of the air bag sensors increasing the risk of
injury. Do not modify the front end of the vehicle.

The SRS consists of:
²driver and passenger air bag modules (which include the inflators and
air bags).
²side air curtains (if equipped). Refer toSide air bag systemlater in
this chapter.
²one or more impact and safing sensors.
²a readiness light and tone.
²diagnostic module.
²and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAir bag readiness
section in theInstrumentationchapter. Routine maintenance of the air
bag is not required.
A difficulty with the system is indicated by one or more of the following:
²The readiness light will either
flash or stay lit.
²The readiness light will not
illuminate immediately after
ignition is turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced at
your dealership or by a qualified technician immediately. Unless serviced,
the system may not function properly in the event of a collision.
Side air curtain system (if equipped)
Do not attempt to service, repair, or modify the air bag
Supplemental Restraint System, its fuses or the seat cover on a
seat containing an air bag. See your Ford or Lincoln Mercury dealer.

The fact that the air curtains did not inflate in a collision does not mean
that something is wrong with the system. Rather, it means the forces
were not of the type sufficient to cause activation. Side air curtains are
designed to inflate in side-impact collisions, not roll-over, rear-impact,
frontal or near-frontal collisions, unless the collision causes sufficient
lateral deceleration.
Several air bag system
components get hot after
inflation. Do not touch them after
inflation.
If the side air curtain has deployed,the air curtain will not
function again. The side air curtain system (including the
A, B and C pillar trim) must be inspected and serviced by a
qualified technician in accordance with the vehicle service
manual.If the air curtain is not replaced, the unrepaired area will
increase the risk of injury in a collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAir bag readiness
section in theInstrumentationchapter. Routine maintenance of the air
bag is not required.
A difficulty with the system is indicated by one or more of the following:
²The readiness light (same light as for front air bag system) will either
flash or stay lit.
²The readiness light will not illuminate immediately after ignition is
turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a collision.

For best results, plug the heater in at least three hours before starting
the vehicle. Using the heater for longer than three hours will not harm
the engine, so the heater can be plugged in the night before starting the
vehicle.
To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is present in exhaust
fumes. Take precautions to avoid its dangerous effects.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
Have the exhaust and body ventilation systems checked whenever:
²the vehicle is raised for service.
²the sound of the exhaust system changes.
²the vehicle has been damaged in a collision.
WARNING:Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemicals known to
the State of California to cause cancer and birth defects or other
reproductive harm. In addition, certain fluids contained in vehicles and
certain products of component wear contain or emit chemicals known
to the State of California to cause cancer and birth defects or other
reproductive harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Improve vehicle ventilation by keeping all air inlet vents clear of snow,
leaves and other debris.

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 lampABS
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 four wheel
ABS is required, apply continuous force on the brake. The four wheel
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 stopping distance. Always leave enough
room between your vehicle and the vehicle in front of you to stop.
²We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
