To continue changing the flat tire, see Removing the Flat Tire and Installing the Spare Tire on page 5-77. Do the following to check the cable: 1. Check under the vehicle to see if the cable is visible. 2. If it is not visible, see Secondary Latch System on page 5-82. If it is visible, first try to tighten the cable by turning the lug wrench clockwise until you hear two clicks or feel it skip twice. You cannot over-tighten the cable. 3. Loosen the cable by turning the wrench counterclockwise three or four turns. 4. If the spare tire has not lowered, tighten the cable all the way and then loosen it at least two times. If the spare tire did lower to the ground, continue with Step 5 under "Removing the Spare Tire (Vehicles with the Rear Convenience Center)" listed previously. 5. If you still cannot lower the spare tire to the ground, see Secondary Latch System on page 5-82. If the spare tire will not lower, the secondary latch could be engaged. 5-76
