Lincoln 2011 Town Car - Manual (Page 208)

WARNING: To help prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block (in
both directions) the wheel that is diagonally opposite (other side and
end of the vehicle) to the tire being changed.
WARNING: If the vehicle slips off the jack, you or someone else
could be seriously injured.
WARNING: Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack or changing the
wheel.
Note: Passengers should not remain in the vehicle when the vehicle is
being jacked.
1. Block the diagonally opposite
wheel.
2. Locate pry off notch (if
equipped) and remove the center
ornament from the aluminum wheel

nut wrench that came with your
vehicle. Insert and twist the handle,
then pry against the wheel.
