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.

5-26 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.
NOTICE:
An aluminum wheel with a flat tire should always
be stored under the vehicle with the hoist.
However, storing it that way for an extended
period could damage the wheel. To avoid this,
have the wheel repaired as soon as possible.
Follow this diagram to store the spare or flat tire.

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 transmission 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 transmission back
and forth, you can destroy your transmission.
For information about using tire chains on your vehicle,
see ªTire Chainsº in the Index.

5-29 Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels. 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 transmission 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. Or, you can use your
recovery hooks if your vehicle has them. If you do need to
be towed out, see ªTowing Your Vehicleº in the Index.
Using the Recovery Hooks
Your vehicle is equipped with recovery hooks. The
recovery hooks are provided at the front of your vehicle.
You may need to use them if you're stuck off
-road
and need to be pulled to some place where you can
continue driving.
