The wheel wrench has a hook that allows you to pull the hoist cable towards you to assist in reaching the spare tire. Be sure the hoist end of the extension connects to the hoist shaft (E). The ribbed square end of the extension is used to lower the spare tire. 4. Turn the wheel wrench (H) counterclockwise to lower the spare tire to the ground. Continue to turn the wheel wrench until the spare tire can be pulled out from under the vehicle. If the spare tire does not lower to the ground, the secondary latch is engaged causing the tire not to lower. See "Secondary Latch System" later in this section. 6. When the tire has been lowered, tilt the retainer (D) at the end of the cable so it can be pulled up through the wheel opening. 7. Put the spare tire near the flat tire. 5-96
