7. Install the bolt cover (if equipped).
8. Reinstall the harness retaining clip into the front of the air filter
assembly.
BRAKE FLUID CHECK
Fluid levels between the MIN and MAX
lines are within the normal operating
range; there is no need to add fluid. If
the fluid levels are outside of the
normal operating range, the
performance of the system could be
compromised; seek service from your
authorized dealer immediately.
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an
electric power steering (EPS) system.
There is no fluid reservoir to check or
fill.
FUEL FILTER
Your vehicle is equipped with a
lifetime fuel filter that is integrated
with the fuel tank. Regular
maintenance or replacement is not
needed.
WASHER FLUID CHECK
WARNING
If you operate your vehicle in
temperatures below 40°F (5°C),
use washer fluid with antifreeze
protection. Failure to use washer fluid
with antifreeze protection in cold
weather could result in impaired
windshield vision and increase the risk
of injury or accident.
Note: The front and rear washer
systems are supplied from the same
reservoir.
Add fluid to fill the reservoir if the level
is low. Only use a washer fluid that
meets Ford specifications. See
Capacities and Specifications
(page 329).
State or local regulations on volatile
organic compounds may restrict the
use of methanol, a common
windshield washer antifreeze additive.
Washer fluids containing
non-methanol antifreeze agents
should be used only if they provide
cold weather protection without
damaging the vehicle’s paint finish,
wiper blades or washer system.

Maintenance

If you see any corrosion on the battery
or terminals, remove the cables from
the terminals and clean with a wire
brush. You can neutralize the acid with
a solution of baking soda and water.
When a battery replacement is
required, the battery should only be
replaced with a Ford recommended
replacement battery that matches
the electrical requirements of the
vehicle.
Because your vehicle’s engine is
electronically-controlled by a
computer, some engine control
settings are maintained by power
from the low voltage battery. Some
engine computer settings, like the idle
trim and fuel trim strategy, optimize
the driveability and performance of
the engine. Some other computer
settings, like the clock and radio
station presets, are also maintained
in memory by power from the low
voltage battery. When a technician
disconnects and connects the low
voltage battery, these settings are
erased. Complete the following
procedure in order to restore the
settings:
1. With the vehicle at a completestop, set the parking brake.
2. Shift the transmission into P.
3. Turn off all accessories.
4. Step on the brake pedal and start the vehicle. 5. Run the engine until it reaches
normal operating temperature.
While the engine is warming up,
complete the following: Reset the
clock. See Audio System (page
124). Reset the power windows
bounce-back feature. See
Windows and Mirrors (page 88).
Reset the radio station presets.
See Audio System (page 124).
6. Allow the engine to idle for at least one minute. If the engine turns off,
step on the accelerator to start the
engine.
7. While the engine is running, step on the brake pedal and shift the
transmission to N.
8. Allow the engine to run for at least one minute by pressing on the
accelerator pedal.
9. Drive the vehicle at least 10 miles (16 kilometers) to completely
relearn the idle and fuel trim
strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy,
the idle quality of your vehicle may be
adversely affected until the engine
computer eventually relearns the idle
trim and fuel trim strategy.
Note: Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized standards
for disposal. Call your local authorized
recycling center to find out more about
recycling automotive batteries.

CLEANING THE EXTERIOR
Wash your vehicle regularly with cool
or lukewarm water and a neutral pH
shampoo, such as Motorcraft® Detail
Wash.
• Never use strong household
detergents or soap, such as dish
washing or laundry liquid. These
products can discolor and spot
painted surfaces.
• Never wash a vehicle that is “hot to the touch” or during exposure
to strong, direct sunlight.
• Dry your vehicle with a chamois or soft terry cloth towel in order to
eliminate water spotting.
• Immediately remove items such as gasoline, diesel fuel, bird
droppings and insect deposits
because they can cause damage
to your vehicle’s paintwork and
trim over time. Use Motorcraft Bug
and Tar Remover.
• Remove any exterior accessories, such as antennas, before entering
a car wash.
Note: Suntan lotions and insect
repellents can damage any painted
surface; if these substances come in
contact with your vehicle, wash off as
soon as possible.
288
Vehicle Care

To clean these items, follow these
tips:
• You can clean the windows with anon-abrasive cleaner such as
Motorcraft Ultra-Clear Spray Glass
Cleaner.
• You can clean the wiper blades with isopropyl rubbing-alcohol or
Motorcraft Premium Windshield
Wash Concentrates in the U.S., or
Premium Quality Windshield
Washer Fluid in Canada. Be sure
to replace wiper blades when they
appear worn or do not function
properly.
• Do not use abrasives, as they may cause scratches.
• Do not use fuel, kerosene, or paint thinner to clean any parts.
If you cannot remove those streaks
after cleaning with the glass cleaner
or if the wipers chatter and move in a
jerky motion, clean the outer surface
of the windshield and the wiper
blades using a sponge or soft cloth
with a neutral detergent or
mild-abrasive cleaning solution. After
cleaning, rinse the windshield and
wiper blades with clean water. The
windshield is clean if beads do not
form when you rinse the windshield
with water.
Note: Do not use sharp objects, such
as a razorblade, to clean the inside of
the rear window or to remove decals,
as this may cause damage to the rear
window defroster’s heated grid lines.CLEANING THE INTERIOR
WARNINGS
Do not use cleaning solvents,
bleach or dye on the vehicle’s
safety belts, as these actions may
weaken the belt webbing.
On vehicles equipped with
seat-mounted airbags, do not
use chemical solvents or strong
detergents. Such products could
contaminate the side airbag system
and affect performance of the side
airbag in a collision.
For fabric, carpets, cloth seats, safety
belts and seats equipped with side
airbags:
• Remove dust and loose dirt with a vacuum cleaner.
• Remove light stains and soil with Motorcraft Professional Strength
Carpet & Upholstery Cleaner.
• If grease or tar is present on the material, spot-clean the area first
with Motorcraft Spot and Stain
Remover. In Canada, use
Motorcraft Multi-Purpose Cleaner.
• If a ring forms on the fabric after spot cleaning, clean the entire area
immediately (but do not
oversaturate) or the ring will set.
• Do not use household cleaning products or glass cleaners, which
can stain and discolor the fabric
and affect the flame retardant
abilities of the seat materials.
291
Vehicle Care

If the leather cannot be completely
cleaned using a mild soap and water
solution, the leather may be cleaned
using a commercially available leather
cleaning product designed for
automotive interiors.
Note:To check for compatibility, first
test any cleaner or stain remover on an
inconspicuous part of the leather.
You should:
• remove dust and loose dirt with a vacuum cleaner.
• clean spills and stains as quickly as possible.
• check for compatibility by first testing any cleaner or stain
remover on an inconspicuous part
of the leather.
Do not use the following products as
these may damage the leather:
• oil/petroleum-based leather conditioners.
• household cleaners.
• alcohol solutions.
• solvents or cleaners intended specifically for rubber, vinyl and
plastics.
CLEANING THE ALLOY
WHEELS
Note: Do not apply a cleaning
chemical to warm or hot wheel rims
and covers.
Note: Some automatic car washes
may cause damage to the finish on
your wheel rims and covers. Note:
Industrial-strength or
heavy-duty cleaners in combination
with brush agitation to remove brake
dust and dirt, could wear away the
clear coat finish over a period time.
Note: Do not use hydrofluoric
acid-based or high caustic-based
wheel cleaners, steel wool, fuels or
strong household detergents.
Note: If you intend parking your vehicle
for an extended period after cleaning
the wheels with a wheel cleaner, drive
your vehicle for a few minutes before
doing so. This will reduce the risk of
increased corrosion of the brake discs.
Alloy wheels and wheel covers are
coated with a clear coat paint finish.
To maintain their condition we
recommend that you:
• Clean the wheels weekly using Motorcraft Wheel and Tire Cleaner.
Apply using manufacturer's
instructions.
• Use a sponge to remove heavy deposits of dirt and brake dust
accumulation.
• Rinse thoroughly with a strong stream of water when you have
completed the cleaning process.
• To remove tar and grease, use Motorcraft Bug and Tar Remover.

Vehicle Care

VEHICLE STORAGE
If you plan on storing your vehicle for
an extended period of time (30 days
or more), read the following
maintenance recommendations to
make sure your vehicle stays in good
operating condition.
All motor vehicles and their
components were engineered and
tested for reliable, regular driving.
Long term storage under various
conditions may lead to component
degradation or failure unless specific
precautions are taken to preserve the
components.
General
• Store all vehicles in a dry,ventilated place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they require regular maintenance to
protect against rust and damage.
Body
• Wash your vehicle thoroughly toremove dirt, grease, oil, tar or mud
from exterior surfaces, rear-wheel
housing and underside of front
fenders.
• Periodically wash your vehicle stored in exposed locations.
• Touch-up exposed or primed metal to prevent rust. • Cover chrome and stainless steel
parts with a thick coat of auto wax
to prevent discoloration. Re-wax
as necessary when your vehicle is
washed.
• Lubricate all hood, door and trunk lid hinges, and latches with a light
grade oil.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and solvents.
Engine
• The engine oil and filter should bechanged prior to storage, as used
engine oil contain contaminates
that may cause engine damage.
• Start the engine every 15 days. Run at fast idle until it reaches normal
operating temperature
• With your foot on the brake, shift through all the gears while the
engine is running.
Fuel system
• Fill the fuel tank with high-qualityfuel until the first automatic
shutoff of the fuel pump nozzle.
294
Vehicle Care

Note:During extended periods of
vehicle storage (30 days or more), fuel
may deteriorate due to oxidation. Add
a quality gas stabilizer product to your
vehicle's fuel system whenever actual
or expected storage periods exceed 30
days. Follow the instructions on the
additive label. your vehicle should then
be operated at idle speed to circulate
the additive throughout the fuel
system.
Cooling system
• Protect against freezing temperatures.
• When removing your vehicle from storage, check coolant fluid level.
Confirm there are no cooling
system leaks, and fluid is at the
recommended level.
Battery
• Check and recharge as necessary.Keep connections clean.
• If storing your vehicle for more than 30 days without recharging
the battery, it may be advisable to
disconnect the battery cables to
ensure battery charge is
maintained for quick starting.
Note: If battery cables are
disconnected, it will be necessary to
reset memory features.
Brakes
• Make sure brakes and parking brake are fully released.
Tires
• Maintain recommended airpressure.
Miscellaneous
• Make sure all linkages, cables,levers and pins under your vehicle
are covered with grease to prevent
rust.
• Move vehicles at least 25 feet (8 meters) every 15 days to lubricate
working parts and prevent
corrosion.
Removing Vehicle From
Storage
When your vehicle is ready to come
out of storage, do the following:
• Wash your vehicle to remove anydirt or grease film build-up on
window surfaces.
• Check windshield wipers for any deterioration.
• Check under the hood for any foreign material that may have
collected during storage
(mice/squirrel nests).
• Check the exhaust for any foreign material that may have collected
during storage.
• Check tire pressures and set tire inflation per the Tire Label.
• Check brake pedal operation. Drive your vehicle 15 feet (4.5 meters)
back and forth to remove rust
build-up.
295
Vehicle Care

Each tire, including the spare
(if provided), should be
checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label. (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label,
you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a Tire
Pressure Monitoring System (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires
is significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to
tire failure. Under-inflation also
reduces fuel efficiency and tire tread
life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale. Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS
malfunction indicator is combined
with the low tire pressure telltale.
When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent the
TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.
The tire pressure monitoring system
complies with part 15 of the FCC rules
and with RSS-210 of Industry Canada.
Operation is subject to the following
two conditions: (1) This device may
not cause harmful interference, and
(2) This device must accept any
interference received, including
interference that may cause undesired
operation.
