ratchet
to the hook near the end of the jack handle
(as illustrated) with the DOWN marking facing you.
Insert the other end through the hole in the rear
bumper and into the hoist shaft.
Turn the ratchet to lower the spare tire
to the ground.
Continue to
turn the ratchet until the spare tire can be
plrlled out from under the vehicle.
When the tire has been lowered.
tilt the retainer at
the end
of the cable so it can be pulled up through
the wheel opening.
Put the spare tire near the flat tire.

The tools you'll be using include the jack (A), the jack
handle extension
(B), the jack handle (C), the wheel
wrench
(D) and the ratchet (E).
If the flat tire is on the rear of the vehicle, you'll need
the jack handle extension
also.
Attach the jack handle (and
jack handle extension, if
needed) to the jack.

If your vehicle has wheel
nut caps, use the wheel
wrench and ratchet
to
remove them. Turn the
wheel wrench
counterclockwise,
with
DOWN fdcing you. to
remove the wheel nut caps.
Then take
off the hub cap.
If the wheel also has a trim ring, LISI: the wheel wrench
to pry along the edge and remove
it.
If the wheel has a smooth center piece or a center piece
with recessed nuts, place the wheel wrench in the slot on
the wheel and gently pry
out.
Removing
the Spare w Flat Tire and Inst-'
1. Use the ratchet and
wheel wrench to loosen
all the wheel nuts. Turn
the wheel wrench
counterclockwise, with
DOWN fdcing you. to
loosen the wheel nuts.
Don't remove the wheel
nuts yet.
2. Position the jack under the vehicle.
Getting under a vehicle when it isjacked 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.

4. Remove all the wheel
nuts and take off the
flat tire.
5. 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 A CAUTIO^:
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.

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 turn
with the ratchet and wheel wrench.
Storing a Flat or Spare Tire aqd Tools
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.
For an underbody spare tire carrier, stow
the tire under
the rear of the vehicle
in the spare tire carrier. To stow
the tire:
1.
2.
3.
4.
5.
Put the tire on the ground at the rear of the vehicle
with the valve stem pointed down and
to the rear.
Tilt
the retainer downward and through the wheel
opening. Make sure that the retainer is
fully seated
across the underside
of the wheel.
Attach the ratchet,
with the UP mark facing you,
near the hook at the end of the jack handle. Insert the
other end, on an angle, through the hole
in the rear
bumper and
into the hoist shaft.
Raise
the tire fully against the underslue 01 le
vehicle. Continue turning the ratchet
until mere are
two “clicks”
or “ratchets.” The spare tire hoist
cannot
be over-tightened.
Grasp and push against
the tire to be sure it is stored
securely and
does not move.

Tires
We don’t make tires. Your new vehicle comes with
high-quality tires made by a leading tire manufacturer.
If you ever have questions about your tire warranty and
where
to obtain service, see your GM Warranty bookJet
for details. Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause overheating
as a result of too much friction. You could
have an airout and a serious accident. See
“Loading Your Vehicle”
m the Index.
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to
be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents.
If your
tread is badly worn, or if your tires have
been damaged, replace them.

Inflation -- Tire Pressure
The Certification/Tire label. which is on the rear edge of
the driver's door, or on the incomplete vehicle document
in the cab, shows the correct inflation pressures for your
tires when they're cold. "Cold" means your vehicle has
been sitting for at least three hours or driven no more
than
I mile (I .6 km).
You can operate some vehicles at reduced inflation
pressures
only when you'll be carrying reduced loads.
On those vehicles, the minimum cold inflation pressures
for a typical reduced load are printed on the Improved
Ride Tire Pressure label located
on the driver's door.
Weigh the vehicle to find the load on each tire and see
the label for the
minimum cold inflation pressures for
that load.

Don't let anyone tell you that underinflation or
overinflation is
all right. It's not. If your tires
don't have enough air (underinflation), you can
get the following:
NOTICE: (Continued)
NOTICE: (Continued)
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
if your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When
to Check
Check your tires once
a month or more. Also, check the
tire pressure of the spare tire,

How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may
look
properly inflated even when they’re underinflated.
Be sure
to put the valve caps back on the valve
stems. They help prevent leaks
by keeping out dirt
.and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 000 to 13 000 km) for any signs of unusual wear. If
unusual wear
is present, rotate your tires as soon as
possible and check wheel alignment. Also check for
damaged tires or wheels. See “When It’s Time for New
Tires” and ‘‘Wheel Replacement” later
in this section for
more information.
If your vehicle has dual rear wheels,
also see “Dual ‘Tire Operation” later
in this section.

The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals.
If
your vehicle has single rear wheels, always use one of
the correct rotation patterns
shown here when rotating
your tires.
If your vehicle has front [Ires with different load ranges
or tread designs (such as all season vs. on/off road) than
the rear tires, don’t rotate your tires front to rear.

If your vehicle has dual rear wheels and the load range
and tread design for your front tires is the same as your
rear tires. always
use one of the correct rotation patterns
shown here when rotating your tires.
11 If your vehicle has dual rear
Q
wheels and the load range
or tread design for
your
~ front tires is different from
your rear tires, always use
the correct rotation pattern shown here when rotating
your tires.
The dual tires are rotated
as a pair, and the inside rear
tires become the outside rear tires.
When
you install dual wheels, be sure the vent holes in
the inner and outer wheels on each side are lined up.
After the tires have been rotated, adjust the front and rear
inflation pressures as shown on the Certificatiomire
label. Make certain that
all wheel nuts are properly
tightened. See “Wheel
Nut Torque” in the Index.
