•Be certain to wash or wipe your hands clean if you have been in
contact with certain products such as insect repellent and suntan
lotion in order to avoid possible damage to the interior painted
surfaces.
•Do not use household or glass cleaners as these may damage the
finish of the instrument panel, interior trim and cluster lens.
WARNING:Do not use chemical solvents or strong detergents
when cleaning the steering wheel or instrument panel to avoid
contamination of the airbag system.
If a staining liquid like coffee/juice has been spilled on the instrument
panel or on interior trim surfaces, clean as follows:
1. Wipe up spilled liquid using a clean, white, cotton cloth.
2. Wipe the surface with a damp, clean, white cotton cloth. For more
thorough cleaning, use a mild soap and water solution. If the spot cannot
be completely cleaned by this method, the area may be cleaned using a
commercially available cleaning product designed for automotive
interiors.
3. If necessary, apply more soap and water solution or cleaning product
to a clean, white, cotton cloth and press the cloth onto the soiled
area–allow this to set at room temperature for 30 minutes.
4. Remove the soaked cloth, and if it is not soiled badly, use this cloth to
clean the area by using a rubbing motion for 60 seconds.
5. Following this, wipe area dry with a clean, white, cotton cloth.
INTERIOR
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 MotorcraftProfessional Strength
Carpet & Upholstery Cleaner (ZC-54).
•If grease or tar is present on the material, spot-clean the area first
with MotorcraftSpot and Stain Remover (ZC-14). In Canada, use
MotorcraftMulti-Purpose Cleaner (CXC-101).
•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.

Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems, try a different brand of unleaded gasoline. If the problems
persist, see your authorized dealer.
Do not add aftermarket fuel additive products to your fuel tank. It
should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. These products have not been approved for your engine and
could cause damage to the fuel system. Repairs to correct the effects of
using an aftermarket product in your fuel may not be covered by your
warranty.
Many of the world’s automakers approved the World-Wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-Wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-Wide Fuel Charter.
Cleaner air
Ford endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality, per the recommendations in theChoosing the right
fuelsection.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
•You may need to cycle the ignition from off to on several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.
•Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8L) may be required.
•The service engine soon
indicator may come on. For more
information on the service engine soon
indicator, refer to
Warning lights and chimesin theInstrument Clusterchapter.
