Near each wheel well is a notch in the frame which
the jack head fits in. The front notch is
9 inches
(23 cm) back from the front wheel well. The rear
notch is
8 inches (20cm) forward from the rear wheel
well.
If your vehicle has flared side moldings, both
front and rear notches are

the wheel wells.
Position the jack and raise the jack head until it fits
firmly into the notch in the vehicle’s frame nearest
the flat tire. Put the compact spare tire near
you.

carefully pull the wheel cover from the wheel. Then
remove the flat tire.
7. 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.

firmly in a criss-cross sequence, as shown.
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.
Don’t try to put
a wheel cover on your compact spare
tire.
It won’t fit. Store the wheel cover and wheel nut
caps 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.

Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after
a the. Check
the inflation pressure regularly. It should be
60 psi
(420 Pa).
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.

Downloaded from www.Manualslib.com manuals search engine When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 Pa).
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 rotated every 6,000 to 8,000 miles
(10
000 to 13 000 km). Any time you notice unusual
wear, 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.
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.

When rotating your tires, always use the correct rotation
pattern shown here.
Don’t include the compact spare tire in your tire rotation. \
After the tires have been rotated, adjust the front and
rear inflation pressures
as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” in
the Index.
