Windshield wiper blades
Check the wiper blades at least twice a year or when they seem less
effective. Substances such as tree sap and some hot wax treatments used
by commercial car washes reduce the effectiveness of wiper blades.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both the windshield and
wiper blades using undiluted windshield wiper solution or a mild
detergent. Rinse thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or other solvents.
Changing the wiper blades
To replace the wiper blades:
1. Pull the wiper arm away from the
windshield and lock into the service
position.
2. Turn the blade at an angle from
the wiper arm. Push the lock pin
manually to release the blade and
pull the wiper blade down toward
the windshield to remove it from the
arm.
3. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.

Automatic disarming
Switching the ignition to the 4 (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.
Key information
Your vehicle is supplied withtwo
coded keys.Only acoded keywill
start your vehicle. Spare coded keys
can be purchased from your
dealership. Your dealership can
program your key or you can ªdo it
yourselfº, refer toProgramming
spare keys.
Large metallic objects, electronic
devices on the key chain that can be
used to purchase gasoline or similar
items, or a second key on the same
key ring as thecoded keymay
cause vehicle starting issues. If
present, you need to keep these
objects from touching thecoded
keywhile starting the engine. These
objects and devices cannot damage
thecoded key,but can cause a
momentary NOÐSTART condition if
they are too close to the key during
engine start. If a problem occurs,
turn ignition OFF and restart the
engine with all other objects on the
key ring held away from the ignition key. Check to make sure thecoded
keyis an approved Lincolncoded key.

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 systems or its fuses. See your Ford or
Lincoln Mercury dealer.
The front passenger air bag is not designed to offer protection to
occupants in the center front seating position.
Modifications to the front end of the vehicle, including frame,
bumper, front end body structure and tow hooks may affect the
performance of the air bag sensors increasing the risk of injury. Do not
modify the front end of the vehicle.
Additional equipment may affect the performance of the air bag
sensors increasing the risk of injury. Please refer to the Body
Builders Layout Book for instructions about the appropriate installation
of additional equipment.
Seating and safety restraints
134

The RCM (restraints control 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 toAir bag readinesssection
in theInstrument clusterchapter. 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 bag system (if equipped)
Do not place objects or mount equipment on or near the air bag
cover on the side of the seatbacks of the front seats or in front
seat areas that may come into contact with a deploying air bag. Failure
to follow these instructions may increase the risk of personal injury in
the event of a collision.
Do not use accessory seat covers. The use of accessory seat
covers may prevent the deployment of the side air bags and
increase the risk of injury in an accident.
Do not lean your head on the door. The side air bag could injure
you as it deploys from the side of the seatback.
Seating and safety restraints
137

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.
All occupants of the vehicle including the driver should always
wear their safety belts even when an air bag SRS is provided.
How does the side air bag system work?
The side air bag system consists of
the following:
²An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
²A special seat cover designed to
allow airbag deployment.
²The same warning light,
electronic control and diagnostic
unit as used for the front air
bags.
²Two crash sensors located under
the outboard side of the front
seats, attached to the floor.
Side air bags, in combination with seat belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated, even if the respective seat is not
occupied. The air bag was designed to inflate between the door panel
and occupant to further enhance the protection provided occupants in
side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates air bag inflation.
Seating and safety restraints
138

The fact that the air bags 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 bags 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 bag has
deployed,the air bag will
not function again. The side
air bag system (including the
seat) must be inspected and
serviced by a qualified
technician in accordance with
the vehicle service manual.If
the air bag 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 side
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.

4. Make sure the parking brake is
set.
5. Turn the key to 4 (ON) without
turning the key to 5 (START).
If there is difficulty in turning the
key, firmly rotate the steering wheel
left and right until the key turns
freely. This condition may occur
when:
²front wheels are turned
²front wheel is against the curb
²steering wheel is turned when getting in or out of the vehicle
Make sure the corresponding lights illuminate or illuminate briefly. If a
light fails to illuminate, have the vehicle serviced.
²If the driver's safety belt is fastened, the
light may not illuminate.

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
