Anti-Lock Brake System Warning light
With anti-lock, this light will go on
when you
start your engine and may stay
on for three seconds or
so. That’s
normal.
If the light doesn’t come on,
have
it fixed so it will be ready to warn
you if there is a problem.
If the light stays on or comes on when
you’re driving, stop
as soon as possible
and
turn the key off. Then start the engine
to reset the system.
If the light still stays
on, or comes on again while you’re
driving, your Oldsmobile needs service. Unless the regular brake system waming
light is
also on, you will still have brakes,
but not anti-lock brakes.
If the regular
brake system warning light
is also on,
see
Brake System Warning Light earlier
in this part.
If the anti-lock brake system warning
light ever flashes, your anti-lock
brake
system is still working but needs
service.
The anti-lock brake system warning
light
may also come on when you are
driving with a compact spare tire.
If this
happens, the light
means you won’t have
anti-lock until you replace
the compact
spare with a full-size tire.
If the warning
light stays on after you replace the
compact spare with
a full-size tire, or if
it comes on again when you’re driving,
your Oldsmobile needs service.

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
- equipment in the passenger
compartment
of the vehicle could
cause injury. In a sudden stop or
~dlision, loose equipment could
>trike someone. Store all these in
the proper place.

Problems on the Road
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.
Don’t use your compact spare on some

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. 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.

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

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

or snagged deep enough to show cord
or fabric.
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.

Buying New Tires
To find out what kind and size of tires
you need, look at the Certification/Tire
label. The tires installed on your vehicle
when it was new had a Tire Performance
Criteria Specification (TPC Spec)
number
on each tire’s sidewall. When
you get new tires, get ones with that
same
TPC Spec number. That way, your
vehicle will continue to have tires that
are designed to give proper endurance,
handling, speed rating, traction, ride
and other things during normal service
on your vehicle.
If your tires have an all-
season tread design, the TPC number
will be followed by a
“MS” (for mud
and snow).
If
you ever replace your tires with those
not having a
TPC Spec number, make
sure they are the same size, load range,
speed rating and construction type (bias,
bias-belted or radial)
as your original
tires. Mixing tires could
cause
you
to lose control while driving.
If you mix tires of different sizes
or types (radial and bias-belted
tires), the vehicle may not handle
properly, and you could have a
crash. Be sure to use the same size
and type tires on all four wheels.
It’s all right
to drive with your
compact spare, though.

developed for use on your vehicle.
Uniform Tire Quality
Grading
The following information relates to the
system developed by the United States
National Highway Traffic Safety
Administration which grades tires by
treadwear, traction and temperature
performance. (This applies only to
vehicles sold
in the United States.)

Used Replacement Wheels Tire Chains
Using the wrong replacement
b wheels, wheel bolts, or wheel
nuts on your vehicle can be
dangerous. It could affect the
braking and handling
of your
vehicle, make your tires lose air
and make you lose control. You
could have a collision in which you
)r others could be injured. Always
lse the correct wheel, wheel bolts,
1 and wheel nuts for replacement.

The wrong wheel can also cause
problems with bearing life, brake cooling, speedometer/odometer
calibration, headlight aim, bumper
height,
vehicle ground clearance,
adtire
or tire chain clearance to

Putting a used wheel on your
vehicle is dangerous. You
can t
know how it’s been used or
how many miles it’s been driven. It
-ould fail suddenly and cause an
,ccident. If
you have to replace a
wheel, use
a new GM original
equipment wheel.
e
Use tire chains only when y
must. Use only SAE Class ‘23’’
type chains that are the proper size
for your tires. Install them on the
front tires and tighten them as
tightly as possible with the ends
securely fastened. Drive slowly
and follow the chain manu-
facturer’s instructions. If
you can
hear the chains contacting your
vehicle, stop and retighten them.
If
the contact continues, slow down
until it stops. Driving too fast with chains on will damage your
vehicle.
