To release the spare tire from the secondary latch, do the following: 4. Lower the jack by turning the folding wrench counterclockwise. Keep lowering the jack until the compact spare tire is resting on the folding wrench. 1. Place the jack under the vehicle, ahead of the rear bumper. Position the center lift point of the jack under the center of the compact spare tire. 2. Turn the folding wrench clockwise to raise the jack until it lifts the secondary latch device under the wheel plate. 3. Keep raising the jack until the compact spare tire stops moving upward and is held firmly in place. This lets you know that the secondary latch has released. 5. Grasp the compact spare tire with both hands and pull it out from under the vehicle. 6. Reach under the vehicle and remove the folding wrench and jack. 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. 5-82
