GMC 2007 Acadia - Manual (Page 463)

Removing the Flat Tire and
Installing the Spare Tire
1. It is recommended that you do a safety check
before preceding. See Changing a Flat Tire
on page 458 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.
3. Loosen the wheel nuts — but do not
remove them — using the lug wrench.
For wheels with a wheel lock key, use the
wheel lock key between the lock nut and
lug wrench. The key is supplied in the front
passenger door pocket.
Notice: If your vehicle has wheel locks and an
impact wrench is used to remove the wheel
nuts, the lock nut or wheel lock key could be
damaged. Do not use an impact wrench to
remove the wheel nuts if your vehicle has
wheel locks.
