Lincoln 2009 MKZ - Manual (Page 222)

Tire change procedure
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 both the front and rear of
the wheel diagonally opposite the
flat tire. For example, if the left
front tire is flat, block the right rear
wheel.
2. Remove the center ornament (if
equipped) from the wheel. Loosen
each wheel lug nut one-half turn
counterclockwise but do not remove
them until the wheel is raised off
the ground.
