12. Reinsert the jack handle into
the jack. Lower the 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.
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
under the spare.
13. Disconnect the jack handle
from the jack and 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 end
of the extension into the hoist
shaft hole in the bumper and
turn the wheel wrench
counterclockwise to lower the
spare the rest of the way.
14. Tilt the tire retainer at the end
of the cable and pull it through
the wheel opening. Pull the tire
out from under the vehicle.
15. If the cable is hanging under
the vehicle, turn the wheel
wrench clockwise to raise
the cable.
Have the hoist assembly
inspected as soon as you can.
A spare or flat tire can not be
stored using the hoist
assembly until it has been
replaced.
