17. Lay the flat tire near the rear of the
vehicle with the valve stem down.
Slide the cable retainer through the
center
of the wheel and raise the flat
tire until you hear the hoist
mechanism click twice. This means
the wheel is firmly stored against
the underside of the vehicle.
When storing the spare tire, be certain
to turn the spare so the valve stem is
near the rear
of the vehicle. This will
help you to check and maintain tire
pressure in the spare.
Push against the tire to be certain it is
stored firmly.
18. Replace all jacking tools as they
were stored in the jack storage
compartment and replace the
compartment cover.
Be sure to also store the nylon nut caps.
When you replace the compact spare
with a full-size tire, replace the nylon
nut caps over the wheel nuts. Tighten
them “hand tight” using the folding
wrench (see step
7).
Storing a jack, a tire or other

Compact Spare Tire
Although the compact spare 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 Pa). The compact spare is
made to go 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.
Your anti-lock brake system warning
light may come on when you are driving
with a compact spare. See the
Index
under Anti-Lock Brake System Warning
Light.

spare can get caught on the rails.
That can damage the tire and
wheel, and maybe other parts
of
your vehicle. And don’t
mix your compact
spare or
wheel with other wheels
or tires. They
won’t fit. Keep your spare
and its wheel
together.

The CertificatiodTire label is found on
the rear edge of the driver's door.
The label shows the size
of your original
tires and the inflation pressures needed
to obtain the gross weight capacity of
your vehicle. This is called the
GVWR
(Gross Vehicle Weight Rating). The
GVWR includes the weight of the
vehicle,
all occupants, fuel and cargo.
The CertificatiodTire label also tells
you the maximum weights for the front
and rear axles, called Gross Axle
Weight Rating (GAWR). To find out the
actual loads on your front and rear
axles, you need to go to a weigh station
and weigh your vehicle. Your dealer can
help you with this. Be sure to spread out your load equally on both sides
of the
centerline.
Never exceed the
GVWR for your
vehicle, or the Gross Axle Weight
Rating (GAWR) for either the &ont or
rear axle.
And, if you do have a heavy load, you
should spread
it out.
Electronic Level Control
On vehicles equipped with optional
electronic level control, the rear of the
vehicle
is automatically kept level as you
load or unload your vehicle. For more
about
this option see the Index under
Electronic Level Control.

I Tires
We don’t make tires. Your new vehicle
comes with high quality tires made
by a
leading tire manufacturer. These tires
are warranted by the tire manufacturers
and their warranties are delivered with
every new Oldsmobile.
If your spare tire
is a different brand than your road tires,
you will have a tire warranty folder from
each
of these manufacturers.
Poorly maintained and improperly used tires are dangerous.
I * Overloading your tires can cause averheating as a result of bo much
fiction. You could have an air-out and a serious accident. See the Index
under Loading Your Wick.
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.

Inflation-Tire Pressure
The CertificatiodTire 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 a
mile. 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:
Too much flexin1
Too much heat
Tire overloadine
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air
(overinflation), you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road
I
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. Simply looking at
the tires will not tell you the pressure,
especially if you have radial tires-
which may look properly inflated even if
they’re underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.

Tire lnspection and Rotation
ro make your tires last longer, have them
[nspected and rotated at the mileages
recommended in the Maintenance
Schedule. See the
Index under
Ycheduled Maintenance Services.
Use this rotation pattern. After the tires
nave been rotated, adjust the front and

When lt's Time for New Tires
One way to tell when it's time for new
tires is to check the treadwear
indicators, which will appear when your
tires have only
2/32 inch (1.6 mm) or
less
of tread remaining.
You need a new tire if:
You can see the indicators at three

The tire has a bump, bulge or split.
The tire has a puncture, cut, or other
damage that can't be repaired well
because of the size or location of the
damage.

Temperature-A, B, C (CONT)
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.
Those grades are molded on the
sidewalls of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles may vary with respect to these
grades, all such tires meet General
Motors performance standards and have
been approved for use on General Motors vehicles.
All passenger type
(P Metric) tires must conform to Federal
safety requirements in addition to these
grades.
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. If wheel nuts keep
coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If
the wheel leaks air out, replace it
(except some aluminum wheels, which
can sometimes be repaired). See your
Oldsmobile 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.
If you need
to replace any of your
wheels, wheel bolts, or wheel nuts,
replace them only with
new GM
original equipment parts.
This way, you
will be sure you have the right wheel,
wheel bolts, and wheel nuts for your Oldsmobile model.

A Word About Maintenance
We at General Motors want to help you keep your vehicle in
good working condition. But we don’t know exactly how
you’ll drive
it. You may drive very short distances only a
few times a week. Or
you may drive long distances all the
time in very hot, dusty weather. You may use your vehicle in
making deliveries.
Or you may drive it to work, to do
errands or in many other ways.
Because of all the different ways people use their
GM vehicles,
maintenance needs vary. You may even need more frequent
checks and replacements than you will find in the schedules
in this part. So please read this part and note how you drive.
If you have any questions on how to keep your vehicle in
good condition, see your Oldsmobile dealer, the place many
GM owners choose to have their maintenance work done.
Your dealer can be relied upon to use proper parts and
practices.
your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures are
important. Improper vehicle maintenance or the removal of
important components can significantly affect the quality of
the air we breathe. Improper fluid levels or even the wrong
tire inflation can increase the level of emissions from your
vehicle.
To help protect our environment, and to help keep
your vehicle
in good condition, please maintain your vehicle
properly.
