2. Position the jack under the vehicle. If the flat tire is
on the front of the vehicle, position the jack on the
frame behind the flat tire.
If the flat tire is on the
rear, position the jack on the rear axle between the
spring and
the shock absorber.
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.
/i CAUTIOL.

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.

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.
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.
6. Replace the wheel nuts
with the rounded end
of
the nuts toward the
wheel. Tighten each
wheel nut by hand
using the wheel wrench
until the wheel
is held
against the hub.

7. Lower the vehicle by rotating the ratchet
and wheel
wrench to the left. Lower the jack completely.
8. Tighten the nuts firmly
in a crisscross sequence
as shown by rotating
the wheel wrench
to
the right.
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 the
proper torque. See "Capacities and
Specifications"
in the Index.

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.
9. Put the wheel trim back on. For vehicles with plastic
wheel
nut caps, tighten the caps until they are
finger-tight, then tighten them an additional one-half
of a turn with the ratchet and wheel wrench.
Storing a Flat or Spare Tire and Tools
A 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 flat tire where the spare tire was stored.

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.

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. I
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. If
you have a
four-wheel drive vehicle, shift into
4HI. Then shift back
and forth between
REVERSE (R) and a forward gear
(or with a manual transmission, between FIRST
(1) or
SECOND (2) and REVERSE (R)), 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 your vehicle has
them.
If you do need to be towed out, see “Towing
Your Vehicle”
in the Index.
Using the Recovery Hooks
Your vehicle may be 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.

The recovery hooks, when used, are under a lot of
force. Always pull the vehicle straight out. Never
pull on the hooks at
a sideways angle. The hooks
could break off and you or others could be
injured from the chain or cable snapping back.
NOTICE:
Never use the recovery hooks to tow the vehicle.
Your vehicle could be damaged and
it would not
be covered
by warranty.
