Roadside Emergencies
6. Lift the vehicle so the tire is no further than 1 inch (2.5 cm) off the
ground when installing the spare tire.
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). To prevent the vehicle
from moving when you change the tire, be sure that the parking brake
is set and the diagonally opposite wheel is blocked. If the vehicle slips
off the jack, someone could be seriously injured.
