5. Turn the wheel wrench (E) counterclockwise to lower the spare tire (H) 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 on page 519 for more information. 6. Use the wheel wrench hook that allows you to pull the hoist cable towards you, to assist in reaching the spare tire. 7. Tilt the tire retainer (G) at the end of the cable when the tire has been lowered, so it can be pulled up through the wheel opening. 8. Put the spare tire near the flat tire. 512
