5-21 Removing the Spare Tire and Tools
The jacking equipment you'll need is stored along the
driver's side inner rear quarter panel. In some cases, you
may have to remove the spare tire in order to reach the
jack. Your vehicle is also equipped with work gloves
and a plastic ground mat to assist in the changing of a
flat tire.
To remove your jack cover,
pull up on the latch(es) on
the cover. Remove the
wheel blocks, jack and
wheel wrench.
The following instructions explain how to remove
the spare tire, depending on where it is mounted on
your vehicle.
NOTICE:
Never remove or restow a tire from/to a stowage
position under the vehicle while the vehicle is
supported by a jack. Always tighten the tire fully
against the underside of the vehicle when restowing.
To remove the
underbody
-mounted spare,
insert the chisel end of the
wheel wrench, on an angle,
into the hole in the rear
bumper. Be sure the chisel
end of the wheel wrench
connects into the hoist shaft.
Turn the wheel wrench counterclockwise to lower the
spare tire. Keep turning the wheel wrench until the spare
tire can be pulled out from under the vehicle.

When the tire has been completely lowered, tilt the
retainer at the end of the cable and pull it through the
wheel opening. Pull the tire out from under the vehicle.
NOTICE:
To help avoid vehicle damage, do not drive the
vehicle before the cable is properly stored.
If you have an inside-mounted spare tire, the tire must
be removed in order to have access to the jack storage.
To remove an inside
-mounted spare tire, reach into your
tire's cover and unscrew the wing nut at the center of the
wheel. Remove it and the retainer. Unhook the tire from
the mounting bracket and remove the cover.
To remove a rear
-mounted spare tire, first make sure
that the carrier arm is fully
-latched to the endgate. Then
remove the spare tire cover.
The locking wheel nut can
be removed by snapping the
rubber weather cover off the
face of the lock case.
Insert the key and pull the
lock case straight off. It is
not necessary to turn
the key.
Put the spare tire near the flat tire.

The tools you'll be using include the jack (A) and wheel
wrench (B). Your vehicle may also have an optional hub
cap removal tool.Position the chisel end of your wheel wrench, or hub cap
removal tool (if equipped), in the notch of the hub cap
and pry off the hub cap.
Some of the molded plastic hub caps have imitation
wheel nuts molded into them. The wheel wrench won't
fit these imitation nuts, so don't try to remove them with
the socket end of the wheel wrench.

If you have individual wheel nut caps that cover each
nut, they must be removed in order to get to the wheel
nuts. Use the socket end of the wheel wrench to remove
the wheel nut caps.
Your wheel nut caps may attach your hub cap to the
wheel. Remove these wheel nut caps before you take off
the hub cap.
Removing the Flat Tire and Installing the
Spare Tire
1. Using the wheel wrench, loosen all the wheel nuts.
Don't remove them yet.

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.

4. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the spare tire
to fit.
5. Remove all the wheel nuts and take off the flat tire.
6. 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.
7. Place the spare on the wheel mounting surface.
8. 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 wheel
wrench and see your dealer as soon as possible.
9. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.

10. Use the wrench to
tighten the wheel nuts
firmly in a crisscross
sequence as shown.
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.
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.
