Mercury Mariner Hybrid 2007 - Manual (Page 239)

Tire change procedure
When one of the front wheels is off the ground, the transaxle
alone will not prevent the vehicle from moving or slipping off the
jack, even if the vehicle is in P (Park).
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.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
1. Park on a level surface, activate
hazard flashers and set parking
brake.
2. Place gearshift lever in P (Park),
turn engine off, and block the
diagonally opposite wheel.
3. Remove the spare tire, jack and
lug wrench.
