Tilt the retainer at the end of the cable and pull it through the wheel opening. Pull the tire out from under the vehicle. 12. If the cable is hanging under the vehicle, turn the wheel wrench in the hoist shaft hole in the bumper clockwise to raise the cable back up. Have the hoist assembly inspected as soon as you can. You will not be able to store a spare or flat tire using the hoist assembly until it has been repaired or replaced. To continue changing the flat tire, return to Step 2 of "Removing the Spare Tire and Tools" earlier in this Section. If the spare tire is hanging from the cable, insert the jack handle, extension and wheel wrench into the hoist shaft hole in the bumper, on an angle, and turn the wheel wrench counterclockwise to lower the spare the rest of the way. 5-24
