the folding wrench clockwise until you hear two
clicks or feel it skip twice. You cannot over-tighten
the cable.
3. Then 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 4 under "Removing the Spare Tire
(Vehicles without the Rear Convenience Center)"
earlier in this section.
5. If you still cannot lower the spare tire to the ground,
see "Secondary Latch System" later in this section.
