Safety belt extension assembly
If the safety belt is too short when fully extended,
there is a 20 cm (8 inch) safety belt extension
assembly that can be added (part number 611C22).
This assembly can be obtained from your dealer at
no cost.
Use only extensions manufactured by the same
supplier as the safety belt. Manufacturer
identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if
the safety belt is too short for you when fully
extended.
Do not use extensions to change the fit of the
shoulder belt across the torso.
Safety belt maintenance
Inspect the safety belt systems periodically to make
sure they work properly and are not damaged.
Inspect the safety belts to make sure there are no
nicks, tears or cuts. Replace if necessary. All safety
belt assemblies, including retractors, buckles, front
seat belt buckle assemblies, buckle support
assemblies (slide bar-if equipped), shoulder belt
height adjusters (if equipped), shoulder belt guide
on seatback (if equipped), child safety seat tether
bracket assemblies (if equipped), LATCH child seat
tether anchors and lower anchors (if equipped), and
attaching hardware, should be inspected after a
collision. Ford Motor Company recommends that all
safety belt assemblies used in vehicles involved in a
collision be replaced. However, if the collision was
minor and a qualified technician finds that the belts
do not show damage and continue to operate
properly, they do not need to be replaced. Safety

amounts of sodium hydroxide may be present which
may irritate the skin and eyes, but none of the
residue is toxic.
While the system is designed to help reduce serious
injuries, contact with a deploying air bag may also
cause abrasions, swelling or temporary hearing loss.
Because air bags must inflate rapidly and with
considerable force, there is the risk of death or
serious injuries such as fractures, facial and eye
injuries or internal injuries, particularly to occupants
who are not properly restrained or are otherwise out
of position at the time of air bag deployment. Thus,
it is extremely important that occupants be properly
restrained as far away from the air bag module as
possible while maintaining vehicle control.
The SRS consists of:
•driver and passenger air bag modules (which
include the inflators and air bags)
•one or more impact and safing sensors
•a readiness light and tone
•a diagnostic module
•and 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.
Several air bag system components get hot
after inflation. Do not touch them after
inflation.
If the air bag has deployed,the air bag will
not function again and must be replaced
immediately.If the air bag is not replaced, the
unrepaired area will increase the risk of injury in a
collision.

STARTING
Positions of the ignition
1. ACCESSORY, allows
the electrical
accessories such as the
radio to operate while
the engine is not
running.
2. LOCK, locks the
steering wheel, automatic transmission gearshift
lever and allows key removal. For vehicle equipped
with a manual transmission, you must depress the
ignition release lever to release the key.
3. OFF, shuts off the engine and all accessories
without locking the steering wheel. This position
also allows the automatic transmission shift lever to
be moved from the P (Park) position without the
brake pedal being depressed.
In the ignition OFF position, the automatic
transmission shift lever can be moved from
the P (Park) position without the brake pedal
depressed. To avoid unwanted vehicle movement,
always set the parking brake.
4. ON, all electrical circuits operational. Warning
lights illuminated. Key position when driving.
5. START, cranks the engine. Release the key as
soon as the engine starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain
control system. This system meets all Canadian
Interference-Causing Equipment standard
requirements regulating the impulse electrical field
strength of radio noise.
When starting a fuel-injected engine, avoid pressing
the accelerator before or during starting. Only use

To release the parking
brake, the brake handle
may need to be pulled
up slightly to release
pressure before
pushing in the button.
Push the button on the
end of the parking
brake handle and push the handle down as far as
possible. Driving with the parking brake applied will
cause the brakes to wear out quickly and reduce fuel
economy.
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.

ABSwarning 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
•In 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.
•The anti-lock system does not reduce stopping
distance. Always leave enough room between your
vehicle and the vehicle in front of you to stop.
•We recommend that you familiarize yourself with
this braking technique. However, avoid taking any
unnecessary risks.
Hydraulic brake booster system (Hydroboost)
The Hydroboost system receives fluid pressure from
the power steering pump to provide power assist
during braking.
The sound of the pump operating may be heard by
the driver, but this is a normal characteristic of the
system.
For Hydroboost-equipped vehicles operating under
normal conditions, the noise of the fluid flowing

3. Start the vehicle.
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 the ignition to the LOCK position and remove
the key 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.

water as soon as possible. Water alone (without
engine coolant) can cause engine damage from
corrosion, overheating or freezing.
•Do not use alcohol, methanol or brine or any
engine coolants mixed with alcohol or
methanol antifreeze (coolant).Alcohol and
other liquids can cause engine damage from
overheating or freezing.
•Do not add extra inhibitors or additives to
the coolant.These can be harmful and
compromise the corrosion protection of the
engine coolant.
•Do not mix with recycled coolant unless from
a Ford-approved recycling process (seeUse of
Recycled Engine Coolantsection).
To reduce the risk of personal injury, make
sure the engine is cool before unscrewing
the coolant pressure relief cap. The cooling system
is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
If you must remove the pressure relief cap or
radiator cap (depending upon engine application),
follow these steps to avoid personal injury:
1. Before you remove the cap, turn the engine off
and let it cool.
2. When the engine is cool, wrap a thick cloth
around the cap. Slowly turn cap counterclockwise
until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been
released, use the cloth to turn it counterclockwise
and remove the cap.
Engine coolant refill procedure-3.8L V6 engine
Note:Use the following procedure when refilling the
cooling system of a vehicle equipped with a 3.8L V6
engine. Failure to follow this warning may result in
damage to the engine and engine cooling system.

when filling an ungrounded fuel container:
•Place approved fuel container on the ground.
•DO NOT fill a fuel container while it is in the
vehicle (including the cargo area).
•Keep the fuel pump nozzle in contact with the
fuel container while filling.
•DO NOT use a device that would hold the fuel
pump handle in the fill position.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with
a 1/8 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/8
of a turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with
the notches on the filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it
stops.
“Check Fuel Cap”illuminates when the ignition is
turned to the ON position to ensure your bulb is
working. When this light turns on, check the fuel
filler cap. Continuing to operate the vehicle with the
Check Fuel Cap light on, can activate the Service
Engine Soon warning. When the fuel filler cap is
properly re-installed, the light(s) will turn off after a
period of normal driving.It may take a long
period of time for the system to detect an
improperly installed fuel filler cap.
If you must replace the fuel filler cap, replace
it with a fuel filler cap that is designed for
your vehicle. The customer warranty may be
void for any damage to the fuel tank or fuel
system if the correct genuine Ford or
Motorcraft fuel filler cap is not used.

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“Service Engine Soon”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 yourWarranty Guidefor complete
emission warranty information.
