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.
8. Place the spare on the
wheel
-mounting surface.
9. Replace the wheel nuts
with the rounded end of
the nuts toward the
wheel. Tighten each nut
by hand until the wheel
is held against the hub.
If a nut cannot be
tightened by hand,
use the wheel wrench
and see your dealer
right away.

10. Lower the vehicle by turning the wheel wrench
counterclockwise. Lower the jack completely.
11. Using the wheel
wrench, tighten the
wheel nuts firmly in
a criss
-cross 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.
12. Store the wheel cover in the trunk until you have
the flat tire repaired or replaced.
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.
When the flat tire has been repaired or replaced,
install the wheel cover. Be sure to position the
alignment pin on the cover with the notch in the
wheel. Apply pressure around the edge of the cap to
snap it in place.
Storing the Flat 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.
After you've put the compact spare tire on your vehicle,
you'll need to store the flat tire in the trunk.
Store the flat tire as far forward in the trunk as possible.
Store the jack and wheel wrench in their compartment in
the trunk. For storage, the jack must be raised until the
screw end is flush with the edge of the jack.

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.
Store the compact spare tire and tools as shown in
the diagram.
The compact spare is for temporary use only. Replace
the compact spare tire with a full size tire as soon as you
can. See ªCompact Spare Tireº later in this section.

Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be 60 psi
(420 kPa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
spare tire is correctly inflated. The compact spare is
made to perform well at speeds up to 65 mph (105
km/h) for distances up to 3,000 miles (5 000 km), so you
can finish your trip and have your full
-size tire repaired
or replaced where you want. Of course, it's best to
replace your spare with a full
-size tire as soon as you
can. Your spare will last longer and be in good shape in
case you need it again.
NOTICE:
When the compact spare is installed, don't take
your vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts of your vehicle.
Don't use your compact spare on other vehicles.
And don't mix your compact spare tire or wheel with
other wheels or tires. They won't fit. Keep your spare
tire and its wheel together.
NOTICE:
Tire chains won't fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don't use tire chains on your
compact spare.

If You're Stuck: In Sand, Mud,
Ice or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you don't want to spin
your wheels too fast. The method known as ªrockingº
can help you get out when you're stuck, but you must
use caution.
CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transaxle or other parts of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you're
stuck, spin the wheels as little as possible. Don't
spin the wheels above 35 mph (55 km/h) as shown
on the speedometer.
NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires. If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
For information about using tire chains on your vehicle,
see ªTire Chainsº in the Index.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will clear
the area around your front wheels. You should turn your
traction control system off. (See ªTraction Control Systemº
in the Index.) If your vehicle has traction control, you should
turn the system off. (See ªTraction Control Systemº in the
Index.) Then shift back and forth between REVERSE (R)
and a forward gear, spinning the wheels as little as possible.
Release the accelerator pedal while you shift, and press
lightly on the accelerator pedal when the transaxle is in gear.
By slowly spinning your wheels in the forward and reverse
directions, you will cause a rocking motion that may free
your vehicle. If that doesn't get you out after a few tries, you
may need to be towed out. If you do need to be towed out, see
ªTowing Your Vehicleº in the Index.
