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.
NOTICE:
Raising your vehicle with the jack improperly
positioned will damage the vehicle or may allow
the vehicle to fall
off the jack. Be sure to fit the
jack lift head into the proper location before
raising
your vehicle.
Do not jack up the vehicle with people in or near
the vehicle.
7. Raise the vehicle by rotating the ratchet clockwise.
Make sure the
UP mark faces you. Raise the vehicle
far enough off the ground
so there is enough room
for the spare tire to fit.
8. Remove all the wheel nuts and take off the flat tire.

3.
Put the flat tire on the ground at the rear of the
vehicle, with the valve stem pointed down.
Tilt retaining bar downward and through the wheel
opening. Make sure it is fully seated across the
underside of the wheel. Attach the ratchet, with the
UP side facing you, to the extension.
Put the
flat end of the extension on an angle through
the hole in the rear door frame, above the bumper.
Turn the ratchet clockwise until the tire is against the
underside
of the vehicle.
You will
feel two “clicks” when the tire is up all the
way. Try to move the tire with your hands to make
sure it is securely in place.
The compact spare is for temporary use only. Replace
the compact spare tire with a full-size tire
as soon as
you can. See “Compact Spare Tire” in the Index. See
the storage instructions label to restore your compact
spare properly.
Return the jacking equipment
to its proper location.

Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi
(420 Wa).
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 posted speed limits for
distances up to
3,000 miles (5 000 km), so you can
fini.sh 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:
I
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.

Windshield Wiper Blade Replacement
To replace your windshield
wiper blade ‘inserts, lift
the wiper arm away‘from
the windshield.
Pinch the two tabs on the wiper arm and slide
the ins1 ert
out of the blade. Slide the new one in place. Make sure
the tabs are locked into position. See “Normal
Maintenance Replacement
Parts” in the Index for the
proper type of replacement blade.
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 wai-ranty booklet
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 air-out and a serious
accident. See “Loading Your Vehicle” in
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 Certificatioflire label, which is on the rear edge of
the driver’s door, 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 1 mile (1.6 km).
NOTICE:
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:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
NOTICE: (Continued) NOTICE: (Continued)
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.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
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.
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
CertificatiodTire label. Make certain that all wheel nuts
are properly tightened. See “Wheel
Nut Torque” in
the Index.
’ A CAUTIO1
Rust or dirt on a wheel, or on the parts to which
it
is fastened, can make 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 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. (See
“Changing
a Flat Tire” in the Index.)

Traction -- A, B, C
The traction grades, from highest to lowest, are A, B,
and C, and they represent the tire’s ability to stop on wet
pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.
Temperature -- A, B, C
The temperature grades are A (the highest), B, and C,
representing
the tire’s resistance to the generation of
heat and its ability
to dissipate heat when tested under
controlled conditions
on a specified indoor laboratory
test wheel. Sustained high temperature can cause
the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead
to sudden tire failure.
The grade
C corresponds to a level of performance
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades
B and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that
is properly inflated and not
overloaded. Excessive speed, underinflation, or excessive loading, either
separately or in combination.
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory
to give you the longest tire life
and best overall performance.
In most cases, you will
not need to have your wheels
aligned again. However, if
you notice unusual tire
wear or your vehicle pulling one way or the other, the
alignment may need to be reset.
If you notice your
vehicle vibrating when driving
on a smooth road, your
wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose,
the wheel,
wheel bolts and wheel
nuts should be replaced. If the
wheel leaks air, replace
it (except some aluminum
wheels, which can sometimes be repaired). See your
GM dealer if any of these conditions exist.
Your dealer will know
the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as
the one it replaces.
