Be especially careful when
inspecting or servicing your
vehicle. Here are some general
precautions for your safety:
²Do not work on a hot engine.
²If you must work with the
engine running, avoid wearing
loose clothing or jewelry that

could get caught in moving
parts. Take precautions with
long hair.
²Do not work on a vehicle with
the engine running in an
enclosed space, unless you are
sure you have enough
ventilation.
²Keep all lit cigarettes, open
flames and other lit material
away from the battery and all
fuel related parts.
If you disconnect the battery, the
engine must ªrelearnº its idle
conditions before your vehicle will
drive properly, as explained in
Batteryin this chapter.

CHECKING AND ADDING
ENGINE OIL
Use WSS-M2C153±F motor oil
CERTIFIED FOR GASOLINE
ENGINES by the American
Petroleum Institute.
Engine oils with an SAE 5W-30
viscosity and displaying the
American Petroleum Institute
certification mark are preferred for
your vehicle. They provide the best
engine performance, fuel economy
and engine protection for all
climates down to ±25ÉC (-15ÉF).
Do not use:
²ªnon-detergentº oils
²oils labeled API SA, SB, SC, SD,
SE, SF or SG
²additional engine oil additives,
oil treatments or engine
treatments
Additional engine oil additives, oil
treatments or engine treatments
are never needed and could, under
certain conditions, lead to engine
damage which is not covered by
your Ford warranty.
Synthetic engine oils which are
CERTIFIED and of the preferred
viscosity may be used in your
engine. The engine oil and oil filter
must still be changed according to
the ªService Guideº.
Checking the engine oil
Check the engine oil each time you
fuel your vehicle.

Using snow tires and chains
Snow tires must be the
same size and grade as the
tires you currently have on your
vehicle.
The tires on your vehicle have
all-weather treads to provide
traction in rain and snow. However,
in some climates, using snow tires
and chains may be necessary. Ford
offers snow chains as a Ford
approved accessory and
recommends use of these or their
equivalents. See your dealer or
qualified service technician for
more information on tire chains for
your vehicle. Follow these
guidelines when using snow tires
and chains:
²Install chains securely, verifying
that the chains do not touch any
wiring, brake lines or fuel lines.
²Install the chains on the rear
tires only.
²Drive cautiously. If you hear the
chains rub or bang against the
vehicle, stop and retighten
Maintenance and care

them. If this does not work,
remove the chains to prevent
vehicle damage.
²Avoid overloading your vehicle.
²Remove the tire chains when
they are no longer needed. Do
not use chains on dry roads.
²The suspension insulation and
bumpers will help prevent
vehicle damage. Do not remove
these components from the
vehicle when using snow tires
and chains.
If equipped with 110 cm (17 inch)
tires, your vehicle will not
accommodate snow chains. Consult
your dealer for information on
other Ford approved methods of
traction control.
IMPORTANT FUEL
INFORMATION
Important safety precautions
Do not overfill the fuel
tank. The pressure in an
overfilled tank may cause
leakage and lead to fuel spray
and fire.
If you do not use the
proper fuel cap, the
pressure in the fuel tank can
damage the fuel system or cause
it to work improperly in a
collision.

Maintenance and care

The fuel system may be
under pressure. If the fuel
cap is venting vapor or if you
hear a hissing sound, wait until it
stops before completely
removing the cap.
Automotive fuels can
cause serious injury or
death if misused or mishandled.
Observe the following guidelines
when handling automotive fuel:
²Extinguish all smoking materials
and any open flames before
fueling your vehicle.
²Always turn off the vehicle
before fueling.
²Automotive fuels can be harmful
or fatal if swallowed. If fuel is
swallowed, call a physician
immediately, even if no
symptoms are immediately
apparent. The toxic affects of
fuel may not be visible for
hours.
²Fuels can also be harmful if
absorbed through the skin. If
fuel is splashed on the skin,
promptly remove contaminated
clothing and wash skin
thoroughly with soap and water.
²If fuel is splashed in the eyes,
remove contact lenses, flush
with water for 15 minutes and
seek medical attention.
²Be particularly careful if you are
taking ªAntabuseº or other
