If the anti-lock brake system warning
light stays on longer than normal after
you’ve started your engine, turn the
ignition
off. Or, if the light comes on
and stays on when you’re driving, stop
as soon as possible and turn the ignition
off. Then start the,engine again to reset
the system. If the light still stays on, or
comes on again while you’re driving,
your Oldsmobile needs service. If the
light
is on but not flashing and the
regular brake system warning light isn’t
on, you still have brakes, but you don’t
have anti-lock brakes.
SERVICE
ENGINE SOON
Malfunction. Indicator Lamp
(Service Engine Soon Light)
A computer monitors operation of your
fuel, ignition and emission control
systems. This light should come on
when the ignition is on, but the engine
is not running, as a check to show you
it is working.
If it does not come on at
all, have it fixed right away. If it stays
on, or it comes on while you are driving,
the computer is indicating that you
have a problem.
You should take your
vehicle in for service soon.

Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi
(105kPa) pressure-type cap and
must be tightly. installed

How To Check Power Steering
When you replace your radiator premre
cap, an
AC@ cap is recommended.
Thermostat
Engine coolant temperature is
controlled by a thermostat in the engine
coolant system. The thermostat stops
the flow of coolant through the radiator
until the coolant reaches a preset
temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
Fluid
-
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
When the engine compartment is hot,
the level should be at the
H mark.
When the engine compartment is
cool, the level 'should be at the
C
mark.

test course. For example, a tire graded
150 would wear one and a half (1 1/2)
times as well on the government course
as a tire graded
100. The relative
performance of tires depends upon the
actual conditions
of their use, however,
and may depart significantly from the
norm due to variations in driving habits,
service practices and differences
in road
characteristics and climate.
Traction - A, B, C
The traction grades, from highest to
lowest are:
A, B, and C. They represent
the tire’s ability to stop onwet
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 (straight-
ahead) 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.
These 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, replace it (except
