11. Remove the jack handle and insert the hoist end of
the extension through the hole in the rear bumper.
Turn the wheel counterclockwise one turn or
until the wheel retainer assembly falls out.

jack by turning the wheel wrench counterclockwise.
Keep lowering the jack until the spare tire slides
off the jack or is hanging by the cable.
{ CAUTION:
Someone standing too close during the
procedure could be injured by the jack. If the
spare tire does not slide off the jack completely,
make sure no one is behind you or on either
side of you as you pull the jack out from the
spare.

carefully remove the jack. Use one hand to push
against the spare while firmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, insert the
hoist handle, extension and wheel wrench into the
hoist shaft hole in the bumper and turn the wheel
wrench counterclockwise to lower the spare the rest
of the way.
