Removing and Replacing Styled Polycast Wheel
Ornaments
To remove a wheel ornament, insert the tapered end of the jack
handle between the ornament and wheel and pry the ornament
from the wheel.
To install the polycast wheel center ornament, you should insert
one side of the ornament into the center of the wheel opening
and strike the opposite side with the palm of your hand until
the ornament is seated in the opening.
Anti-Theft Wheel Lug Nuts (If equipped)
If your vehicle has this option, one of the lug nuts on each
wheel locks and must be unlocked with a special key. If you
lose the key, send the registration card to the manufacturer (not
to the dealer) to get a replacement key.
NOTE: If you lose your lug wrench/lug nut key assembly, see
your nearest Ford or Lincoln/Mercury dealer who has
access to a master set of keys.
NOTE: DO NOT USE A POWER IMPACT WRENCH ON
THE LUG NUT KEY.
