GMC 2008 Acadia - Manual (Page 390)

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 5-81.
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 did lower to the ground, continue
with Step 5 under “Removing the Spare Tire” listed
previously.
5. If you still cannot lower the spare tire to the ground,
see Secondary Latch System on page 5-81.
Removing the Flat Tire and
Installing the Spare Tire
1. Do a safety check before proceeding. See Changing
a Flat Tire on page 5-72 for more information.
2. If the vehicle has a wheel cover, loosen the plastic
nut caps with the wheel wrench. They will not come
off. Then, using the flat end of the wheel wrench,
pry along the edge of the cover until it comes off. Be
careful; the edges may be sharp. Do not try to
remove the cover with your bare hands.
Store the wheel cover securely in the rear of the
vehicle until you have the flat tire repaired or
replaced.
If your vehicle has aluminum wheels, remove the
wheel nut caps using the wheel wrench.
