{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. 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 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. 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. 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. 5-84
