Tire change procedure
1. Turn engine off and block the
wheel that is diagonally opposite of
the flat tire using the wheel chock,
if equipped.If the vehicle is a
4x4,lock the manual hub on the
wheel.
2. Remove the jack, jack handle, lug wrench and spare tire from the
stowage locations.
3. Use the tip of the lug wrench to remove any wheel trim.
4. Loosen each wheel lug nut one-half turn counterclockwise but do not
remove them until the wheel is raised off the ground.
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 R (Reverse) (manual transmission). To help 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, you or someone else could be
seriously injured.
