vhile using them. Your vehicle also has
:he flow-through ventilation system
iescribed later in this section.
3FF: Press to turn the blower off. Air
vi11 still come from the outlets at the
loor. Press any function button to turn
.he system on.
remperature Control Lever: This lever
:hanges the temperature of the air
:oming through the system. The higher
.he lever setting, the warmer the air.
8: Selects the force of air you want.
Press
LO to lower the fan speed, HI to
raise it.
Air Conditioning
On very hot days, open the windows
long enough to let hot inside air escape.
This reduces the time it takes for your
vehicle to cool down, which should help
fuel economy.
There are three
air conditioning settings:
MAX: Provides maximum cooling or
quick cool-down on very hot days. This
setting also helps prevent outside odors
from entering your vehicle.
This setting recirculates much of the air
inside your vehicle, and it should not be
used for long periods because the air
may become too cold and dry. This
setting is not recommended if an
occupant is smoking.
NORM: Use for normal cooling on hot
days. This setting brings in outside air, cools
it and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use on cool, but
sunny days. This setting brings in
outside air, but directs it in two ways.
The cool air is directed to the upper
portion of your body through the
instrument panel outlets, but most
warmed air is directed through the
heater ducts and a little to the defrost
and side window vents. At times this
temperature difference may be more
apparent than others.
Heating and Ventilation
When you don’t need to cool the
outside air, use these next settings. You
can leave the air as it is or heat it.
The air conditioner compressor doesn’t
run in these settings. This reduces the
engine load, resulting in improved fuel
economy (gas mileage).
VENT: For mild outside temperatures,
when little heating or cooling is needed,
push
VENT. Air flow is through the
instrument panel outlets. Slide the
temperature control lever to a
comfortable level.

HEAT: When outside temperatures are
cold, push
HEAT. Slide the
temperature control lever to a
comfortable level. For maximum
heating, slide it all the way to the right.
This setting will send
most of the
heated air through the ducts near the
floor. The rest will come out of the
defroster vents and side window
defogger vents.
There are two settings for clearing your
windows. For each setting, adjust-the
temperature control as desired. The air
conditioner compressor will run in
these settings to remove,moisture
from-
the air when the temperature is above
freezing.
This setting allows half of
the air to flow to the floor
heater ducts, and half to go
8Qjfl
to the~windshield and side window
vents located in the windshield pillars.
Use this setting to warm passengers
while keeping the windshield clear. The
DEF setting directs 90% of the
air
through the defroster vents and the side
window vents, and
10% to the floor. To
rapidly defrost the windshield, slide
the temperature control .lever all the
way to WARM and press the DEF
button.
Adjust the fan to the highest speed.

(OPTION)
This system allows you to set the
temperature
you want. It also lets you
choose automatic air flow and direction
control, or air flow and direction
settings you select. Your vehicle also
has the flow-through ventilation system
described later in this section.
The digital screen displays the outside
temperature, the inside temperature
setting and the fan speed.
When you select the
AUTO mode, the
air conditioner compressor
will operate
if the outside temperature is above
freezing.
The air conditioner compressor also
operates in
DEFOG, DEF (Defrost) and
BI-LEV (Bi-Level)
when the
outside temperature is above freezing.
COOL/WARM: Sets the interior
temperature you want. Press
COOL to
lower the inside temperature setting;
press
WARM to raise the setting. The
temperature you set will be displayed on
the digital screen.
Once you set the temperature, the
system will try to maintain the set
temperature, whether. you are using the
heating or cooling controls.
Your system has an interior
temperature sensor that dete.cts
increased interior temperature caused
by sunlight. To keep you comfortable, it
reduces the interior temperature by as
much as
5°F (3°C) below the setting on
the digital screen.
AUTO: To allow the system to
automatically control the temperature,
air distribution and fan speed:
1. Set the temperature you want with
the
COOL/WARM switch.
2. Press the AUTO switch. The AUTO
symbol will appear on the digital
screen.
The system will approach the
temperature you select as quickly as
possible.
For most efficient operation,
just set the system temperature where
you would like it and drive away.
You may notice a delay of three or four
minutes before the blower comes on.
OUTS TEMP: Press to have the
outside temperature displayed
on the
digital screen. Press
again to return to
the inside temperature setting.
If the system is left in the outside
temperature mode, the outside
temperature will be displayed except
when changing the inside temperature
setting using the
COOL/WARM
switch. The display will return to the
outside temperature setting in about
five seconds.

Use the following controls when the
system is not set on
AUTO:
8: Press.the top of the switch to raise
the fan speed, the bottom of the switch
to lower the fan speed. The fan symbol
and bar graph will be displayed on the
digital screen.
When the
AUTO switch is pressed, the
fan symbol will go out and the fan will
return to automatic operation.
If the Fahrenheit (F") or Celsius (C")
symbol begins to flash, or flashes when
you turn on the ignition, it indicates an
electrical problem with your air
conditioning system. The flashing will
continue for about two minutes. It
means you should have your system
serviced.
Directional Controls
When the following buttons are pressed,
an indicator light will glow above the
button.
BI-LEV (Bi-Level): Use on cool, but
sunny days. This setting brings in the
outside air, but directs it in
two ways.
The cool air is directed to the upper
portion of your body through the instrument
panel outlets, but most
warmed air is directed through the
heater ducts and a little to the defrost
and side window vents. At times this
temperature difference may be more
apparent than others.
You may notice a delay of three or four
minutes before the blower comes on.
UPPER: Press to direct air flow
through the instrument panel outlets
only.
LOWER Press to direct 90% of the air
flow through the heater ducts, and
10%
of the air flow through the windshield
defroster vents.
DEFOG: Press to direct half the air to
the windshield, and the other half
through the heater ducts.
DEF (Defrost): Press to direct 90% of
the air to the windshield and side
window vents, and
10% to the floor.
The fan will automatically go to high.
For a lower fan speed, press the fan
switch.
OFF: Press to turn off the system.
Some air will still come from the outlets
at the floor.

sound may come and go or be heard all
the time your vehicle is moving (except
when you are pushing
on. the brake
pedal firmly).
NOTICE:
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climates
may cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean something
is wrong with your brakes.
Brake linings should always be replaced
as complete axle sets.
Brake Pedal Travel-
See your dealer if the brake pedal does
not return to normal height, or if there
is a rapid increase in pedal travel. This
could be a sign
of brake trouble.
Brake Adjustment
Every time you male a moderate brake
stop, your disc brakes adjust for wear. If
you rarely make a mo.derate or heavier
stop, then your brakes might not adjust
correctly.
If you drive in that way, then
- very carefully - make a few
moderate brake stops about every
1,000
miles (1 600 km) , so your brakes will
adjust properly.
Replacing Brake System Parts
The braking system on a modern
vehicle is complex. Its many parts have
to be of top quality and work well
together
if the vehicle is to have really
good braking. Vehicles we design and
test have top-quality
GM brake parts in
them, as your Oldsmobile does when it
is new. When you replace parts of your
braking system
- for example, when
your brake linings wear down and you have
to have new ones put in
- be sure
you get new genuine
GM replacement
parts.
If you don’t, your brakes may no
longer work properly. For example, if
someone puts.in brake linings that are
wrong for your vehicle, the balance
between your front and rear brakes can
change, for the worse; The braking
performance you’ve come to expect can
change in many other ways if someone
puts in the wrong replacement brake
parts.

Service & Appearance Care
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
