Follow these instructions to lower the spare tire: 1. One side of the ratchet has an UP marking. The other side has a DOWN marking. Assemble the ratchet to the hook near the end of the jack handle (as illustrated) with the DOWN marking facing you. Insert the other end through the hole in the rear bumper and into the hoist shaft. If your two-door utility model has a jack cover, turn the wing nut counterclockwise and take the cover off. 2. Turn the ratchet to lower the spare tire to the ground. Continue to turn the ratchet until the spare tire can be pulled out from under the vehicle. 3. When the tire has been lowered, tilt the retainer at the end of the cable so it can be pulled up through the wheel opening. 4. Put the spare tire near the flat tire. To take the jack out, turn the wing nut counterclockwise and take it and the retainer off. Take the jack and storage box out and take the tools out of the box. Your vehicle may have a pair of emergency gloves secured to the jack. You can use them when changing the tire, or during other emergency situations. Remember to replace them with the jack, so you will have them if needed later. 5-24
