FORD 2012 Expedition v.2 - Manual (Page 295)

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 the
wheels (both front or both rear) on the opposite end of the vehicle
from the wheel being changed. If on a grade, block both opposite
wheels on the downward side of the hill.
WARNING: If the vehicle slips off the jack, you or someone else
could be seriously injured.
WARNING: On vehicles equipped with air suspension, turn off
the Air Suspension system prior to jacking, hoisting or towing
your vehicle.
WARNING: Turn off the running boards (if equipped) before
jacking or placing any object under the vehicle. Never place your
hand between the extended running board and the vehicle. A moving
running board may cause injury.
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 and changing the
wheel.
Note: Passengers should not remain in the vehicle when the vehicle is
being jacked.
If your vehicle is equipped with air suspension, refer to Message center
in the Instrument Cluster chapter for instructions on turning the air
suspension system off.
Refer to the instruction sheet (located in the rear floor compartment
behind the 3rd row seat with the jack tray tools assembly kit) for
detailed tire change instructions.
