4. Raise the vehicle by turning the jack handle to the
right. 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.
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.

/I 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 to the
left. Lower the jack completely.

10. Use the wrench to
tighten the wheel nuts
firmly in
a crisscross
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.
Storing a Flat or Spare Tire and Tools
A 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 Nom). 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.

If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help
you get out when you’re stuck, but
you must use caution.
A 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.
I
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 “Tire Chains”
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. Shift the transfer
case into
4HI. 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.
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 you do need to be towed out, see
“Towing Your Vehicle”
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.

often
to check the lubricant. See “Periodic Maintenance

you’ll need to add some lubricant. Add enough lubricant
to raise
the level to the bottom of the filler plug hole.
Refer to the Maintenance Schedule to determine what
kind
of lubricant to use. See “Recommended Fluids and
Lubricants” in the Index.
