SAFETY AND ENVIRONMENT PROTECTION
Warning symbols in this guide
How can you reduce the risk of personal injury to yourself or others? In
this guide, answers to such questions are contained in comments
highlighted by the warning triangle symbol. These comments should be
read and observed.
Warning symbols on your vehicle
When you see this symbol, it is
imperative that you consult the
relevant section of this guide before
touching or attempting adjustment
of any kind.
Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste, cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. See Engine oilin the
Maintenance and Specifications chapter for more information on oil
usage.

Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your dealer immediately.
Anti-lock brake system:
Illuminates indicating an ABS fault.
If the lamp stays on for more than a
few seconds, then an ABS fault is
indicated, have the system serviced
immediately. Normal braking is still functional unless the brake warning
light also is illuminated.
Check gage: Illuminates when any
of the following conditions has
occurred:
• The engine coolant temperature
is high.
• The engine oil pressure is low.
• The fuel gauge is at or near empty.
• The charging system is malfunctioning.
Air bag readiness: If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also
sound when a malfunction in the supplemental restraint system has been
detected.
Safety belt: Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Anti-theft system: Flashes when
the Securilock Passive Anti-theft
System has detected a fault.

Never remove the coolant reservoir cap while the engine is
running or hot.
Tachometer: Indicates the engine
speed in revolutions per minute.
Driving with your tachometer
pointer continuously at the top of
the scale may damage the engine.
Engine oil pressure gauge:
Indicates engine oil pressure. If the
pointer drops to the red section
when the engine is running, stop
your vehicle as soon as possible,
shut off the engine and check the
oil tank level. Add oil if necessary.
Do not continue to operate your
engine as long as the pointer is in the red section. Otherwise, your
engine may be severely damaged.
If the gauge indicates zero or very low oil pressure (needle in the
red section) stop the vehicle and engine as soon as safe to do so
and check the engine oil tank level.
After running, the engine may be hot. Allow the engine to cool
before handling any components.
Voltmeter gauge: Measures the
battery charging voltage. If the
pointer moves above or below the
normal operating range under
normal vehicle operation, have your
vehicle ’s electrical system checked.

hot wax treatments used by commercial car washes, tree sap, or other
organic contamination. To clean these items, please follow these tips:
•The windshield, rear windows and side windows may be cleaned with
a non-abrasive cleaner such as Motorcraft Ultra Clear Spray Glass
Cleaner (ZC-23), available from your dealer.
• Do not use abrasives, as they may cause scratches.
• Do not use fuel, kerosene, or paint thinner to clean any parts.
• Wiper blades can be cleaned with isopropyl (rubbing) alcohol or
windshield washer solution. Be sure to replace wiper blades when they
appear worn or do not function properly.
Do not use sharp objects, such as a razor blade, to clean the
inside of the rear window or to remove decals, as it may cause
damage to the rear window defroster ’s heated grid lines.
INSTRUMENT PANEL AND CLUSTER LENS
Clean the instrument panel with a damp cloth, then dry with a dry cloth.
• Avoid cleaners or polish that increase the gloss of the upper portion of
the instrument panel. The dull finish in this area helps protect the
driver from undesirable windshield reflection.
Do not use chemical solvents or strong detergents when cleaning
the steering wheel or instrument panel to avoid contamination of
the air bag system.
•
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.
SAFETY BELTS
For safety belts:
• Remove dust and loose dirt with a vacuum cleaner.
• Remove light stains and soil with Motorcraft Extra Strength
Upholstery Cleaner (ZC-41).
• If grease or tar is present on the material, spot-clean the area first
with Motorcraft Spot and Stain Remover (ZC-14).
• Never saturate the safety belts with cleaning solution.
• Do not use household cleaning products or glass cleaners, which can
stain and discolor the fabric and affect flame retardant abilities.
