side wall and down to release the tabs securing the
top of the cover.

counterclockwise.

blocks off the bolt.

the pouch.

5-24 Removing the Flat Tire and Installing the
Spare Tire
1. Before you start, block the front and rear of the tire
farthest away from the one being changed. Then put
your spare tire near the flat tire.

socket to loosen all the wheel nuts. Don't remove
them yet.
3. The jack has a bolt on the end. Attach the socket end
of the extension to the jack bolt.

CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to fit the
jack lift head into the proper location before
raising the vehicle.7. Raise the vehicle by turning the ratchet clockwise.
Make sure the UP mark faces you. Raise the vehicle
far enough off the ground so there is enough room
for the spare tire to fit.
8. Remove all the wheel nuts and take off the flat tire.

9. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later, if you need to, to get all the rust
or dirt off.
CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.
10. Put on the spare tire. Put the nuts on by hand.
Make sure the cone
-shaped end is toward the
wheel. Tighten each nut by hand until the wheel
is held against the hub. If a nut can't be turned
by hand, use the extension and see your dealer
as soon as possible.

CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come off. This could lead to an accident.
Be sure to use the correct wheel nuts. If you have
to replace them, be sure to get new GM original
equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to
100 lb
-ft (140 N´m).
NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification.
13. Remove the wheel blocks.
NOTICE:
Wheel covers won't fit on your compact spare.
If you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.
Storing a Flat or Spare Tire and Tools
CAUTION:
Storing a jack, a tire or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
1. Put the flat tire on the ground at the rear of the
vehicle, with the valve stem pointed down.
2. Tilt the retainer plate downward and through the
wheel opening. Make sure it is fully seated across the
underside of the wheel. Attach the ratchet, with the
UP side facing you, to the extension.
