Removing the Spare Tire and Tools
Lift and remove the cover. (See “Compact Spare Tire”
later in this section for more information about the
compact spare.) You will find
the jacking instructions
label on the underside of the tire cover. Turn the wing
nut
counterclockwise and
remove it. Then lift off the
adapter and remove the
spare tire.
Remove the jack and wheel wrench
from the trunk.
Your vehicle’s jack and wheel wrench are store in
a
foam tray.

The tools you'll be using include the jack (A) and wheel
wrench
(B).
Removing the Flat Tire and Installing the
Spare Tire
1. Remove the wheel nut caps, if your vehicle has them
(you may need to use the wheel wrench to loosen
and remove them, if your fingers do not fit into this
small area).
2. On some models, a cover plate must be removed to
find the wheel nuts. Carefully use the wedge end
of
the wheel wrench to pry it off.

3. Then use the wheel wrench to loosen all the wheel
nuts. Don’t remove them yet.

the flat tire. Put the compact spare tire near
you.

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.
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 your vehicle.
1 NOTICE: I
Do not jack or lift the vehicle using the oil pan.
Pans could crack and begin to leak fluid.
5. Raise the vehicle by rotating the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the spare tire
to
fit.
6. Remove all of the wheel nuts.

7. Remove the wheel cover from the wheel, if your
vehicle has them. Then take
off the flat tire.
8. Remove any rust or dirt
from the wheel bolts, mounting surfaces and
spare wheel.
A CAUTION:
Rust or dirt on the w , 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.

11. Tighten the wheel nuts
firmly in a criss-cross
sequence, as shown.
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.
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). Don’t
try to put
a wheel cover on your compact spare
tire. It won’t fit. Store the wheel cover and wheel nut
caps in the
trunk until you have the flat tire repaired
or replaced.

I 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 the Flat Tire and Tools
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.
Store the flat tire in the compact spare tire compartment.
Place the tire in the compartment, then secure the
adapter, extension (aluminum wheels only) and wing
bolt. Store the jack and wheel wrench
in the foam tray.
