children’s reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil fromyour hand could cause the bulb to
break the next time the headlamps are operated.

bulb’s plastic base facing upward. Turn the bulb slightly to align the
grooves in the plastic base with the tabs in the lamp assembly.

The air bags inflate and deflate
rapidly upon activation. After air bag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder or sodiumcompounds which
may irritate the skin and eyes, but
none of the residue is toxic.
While the SRS is designed to help
reduce serious injuries, contact with
a deploying air bag may also cause
abrasions, swelling or temporary
hearing loss. Because air bags must
inflate rapidly and with considerable
force, there is the risk of death or
serious injuries such as fractures, facial and eye injuries or internal
injuries, particularly to occupants who are not properly restrained or are
otherwise out of position at the time of air bag deployment. It is
extremely important that occupants be properly restrained as far away
from the air bag module as possible while maintaining vehicle control.
The SRS consists of:
•driver and passenger air bag modules (which include the inflators and
air bags)
•one or more impact and safing sensors
•a readiness light and tone
•a diagnostic module
•and the electrical wiring which connects the components
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (including the impact
sensors), the systemwiring, the air bag systemreadiness light, the air
bag back up power and the air bag ignitors.
Several air bag systemcomponents get hot after inflation. Do not
touch themafter inflation.
If the air bag has deployed,the air bag will not function
again and must be replaced immediately.If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.

When replacing full size tires, never mix radial bias-belted, or
bias-type tires. Use only the tire sizes that are listed on the
Certification or Tire Label. Make sure that all tires are the same size,
speed rating, and load-carrying capacity. Use only the tire combinations
recommended on the label. If you do not follow these precautions,
your vehicle may not drive properly and safely.
Make sure that all replacement tires are of the same size, type,
load-carrying capacity and tread design (e.g., “All Terrain”,
“Touring”, etc.), as originally offered by Ford.
Failure to follow these precautions may adversely affect the
handling of the vehicle, and increase the risk of loss of vehicle
control, vehicle rollover and/or personal injury.
Tires that are larger or smaller than your vehicle’s original tires may also
affect the accuracy of your speedometer.
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, you may need to use snow
tires and chains. If you need to use snow tires and chains, it is
recommended that steel wheels are used of the same size and
specifications as those originally installed.
Follow these guidelines when using snow tires and chains:
•Do not use tire chains on aluminum wheels. Chains may chip the
wheels.
•SAE Class S chains may be used on P185/65R14 tires.
•Do not use tire chains with 38 cm(15 inch) wheel/tire options. Using
chains on this size tire may cause damage to steering, suspension
and/or body components.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
