•It is especially important to wash the vehicle regularly during the
winter months, as dirt and road salt are difficult to remove and cause
damage to the vehicle.
•Immediately remove items such as gasoline, diesel fuel, bird droppings
and insect deposits because they can cause damage to the vehicle’s
paintwork and trim over time. Use Bug and Tar Remover, ZC-42,
which is available from your authorized dealer.
•Remove any exterior accessories, such as antennas, before entering a
car wash.
•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.
•If your vehicle is equipped with running boards, do not use
rubber, plastic and vinyl protectant products on the running
board surface, as the area may become slippery.
Exterior chrome
•Wash the vehicle first, using cool or lukewarm water and a neutral pH
shampoo, such as Motorcraft Detail Wash (ZC-3-A).
•Use Custom Bright Metal Cleaner (ZC-15), available from your
authorized dealer. Apply the product as you would a wax to clean
bumpers and other chrome parts; allow the cleaner to dry for a few
minutes, then wipe off the haze with a clean, dry rag.
•Never use abrasive materials such as steel wool or plastic pads
as they can scratch the chrome surface.
•After polishing chrome bumpers, apply a coating of Motorcraft
Premium Liquid Wax (ZC-53-A), available from your authorized dealer,
or an equivalent quality product to help protect from environmental
effects.
WAXING
Applying Motorcraft Paint Sealant (ZC-45) to your vehicle every six
months will assist in reducing minor scratches and paint damage.
•Wash the vehicle first.
•Do not use waxes that contain abrasives; use Motorcraft Premium
Liquid Wax (ZC-53-A), which is available from your authorized dealer,
or an equivalent quality product.
•Do not allow paint sealant to come in contact with any non-body
(low-gloss black) colored trim, such as grained door handles, roof

•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
•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.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
intervals listed inscheduled maintenance information.The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -34°F (-36°C). Coolant concentration
testing is possible with a hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014–R1060). The level of coolant
should be maintained at the “FULL COLD” level or within the “COLD
FILL RANGE” in the coolant reservoir. If the level falls below, add
coolant per the instructions in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•Freeze protection down to -34°F (-36°C).
•Boiling protection up to 265°F (129°C).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.

swallowed can cause death or permanent injury. If fuel is swallowed,
call a physician immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be visible for hours.
•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
•Be particularly careful if you are taking “Antabuse” or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
When refueling always shut the engine off and never allow
sparks or open flames near the filler neck. Never smoke while
refueling. Fuel vapor is extremely hazardous under certain conditions.
Care should be taken to avoid inhaling excess fumes.
The flow of fuel through a fuel pump nozzle can produce static
electricity, which can cause a fire if fuel is pumped into an
ungrounded fuel container.

•Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
•Have the items listed inscheduled maintenance information
performed according to the specified schedule.
The scheduled maintenance items listed inscheduled maintenance
informationare 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
indicator, 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.
An improperly operating or damaged exhaust system may allow exhaust
to enter the vehicle. Have a damaged or improperly operating exhaust
system inspected and repaired immediately.
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.
On board diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the On
