FORD 2010 Edge v.2 - Manual (Page 252)

Tire change procedure
WARNING: When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the vehicle is in P (Park).
WARNING: To help prevent the vehicle from moving when you
change a tire, be sure to place the transmission in P (Park), set
the parking brake and 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. Remove wheel cover (if
equipped) with the lug wrench tip
and loosen each wheel lug nut
one-half turn counterclockwise but
do not remove them until the wheel
is raised off the ground.
