To continue changing the flat tire, see Removing the
Flat Tire and Installing the Spare Tire on page 5-77.

be engaged.

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.
