Rear Tire Changing Procedure
1. Do a safety check before proceeding. See Changing
a Flat Tire on page 6-84 for more information.
2. Using the wheel wrench, loosen all the wheel nuts
on the rear tire. Do not remove them yet.
3. Position the jack on the rear position and raise the
jack lift head to fit over the car flange under the
down arrow markings on the rocker panel.

Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under a
vehicle when it is supported only by a jack.
