FORD 2002 Explorer v.3 - Manual (Page 238)

Tire change procedure
To 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.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
Refer to the tire changing instruction sheet for detailed tire change
instructions.
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
2. Place gearshift lever in P (Park)
or in the reverse gear (manual
transmission) and turn engine OFF.
When one of the rear
wheels is off the ground,
the transmission alone will not
prevent the vehicle from moving
or slipping off the jack, even if the
transmission is in P (Park)
(automatic transmission) or
reverse (manual transmission).
3. Block the diagonally opposite
wheel.
4. Use the tip of the lug wrench to
remove any beauty cap by twisting
the tip under the cap. The carpeted
floor lid can be used as a kneeling
pad.
