This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine is too
hot! It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and

MODE CONTROL: The right control knob changes
the functions
of your system.
VENT: Use when outside temperatures are mild, and
little heating or cooling is needed. Air flow is through
the instrument panel outlets.
Set the center control knob
to the temperature desired.
BI-LEV: 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 slightly
warmer air is directed through the heater ducts and
defroster vents. At times this temperature difference
may be more apparent than others.
HEAT This setting brings heated air through the heater
ducts, and some through the windshield defroster vents.
If you have the optional engine coolant heater (engine
block heater) and
use it during cold weather, 0°F
(- 1 8’ C) or lower, your heating system will more quickly
provide heat because the engine coolant is already
warmed. See “Engine Coolant Heater (Engine Block
Heater)” in the Index.
DEFOG: This setting divides air flow equally between
the heater ducts and the windshield defroster vents.
DEF: This setting directs air through the
windshield defroster vents located on top
of the
instrument panel.
Defogging Windows
To defog the windshield, turn all three control knobs to
the far right.

Air Conditioning System (Option)
The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also has the flow-through ventilation system described
later in this section.
Air Conditioning
Your system has three air conditioner settings in
addition to the standard climate control system. Before using
your air conditioner
on very hot days, open the
windows long enough to let hot inside air escape. This
reduces the amount of work your air conditioner's
compressor will have
to do, which should help fuel
economy.
MAX: Use for maximum cooling. This setting
recirculates much of the air inside your vehicle
so it
maximizes your air conditioner's performance and your
vehicle's fuel economy.
NORM: Use for normal cooling on hot days. This
setting cools outside air and directs it through the
instrument panel outlets.
BI-LEV: 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 slightly
warmer air is directed through the heater ducts and
defroster vents. At times this temperature difference
may be more apparent than others.
The air conditioner compressor is enabled in all three air
conditioning positions.

Hill and Mountain Roads

or rolling terrain. .ins
is different
from
If you drive regularly in steep country, or if you’re
planning
to visit there, here are some tips that can make
your trips safer and more enjoyable.

Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transaxle. These parts can work hard on mountain
roads.
Know how to go down hills. The most important
thing to know is this:
let your engine do some of the
slowing down. Shift
to a lower gear when you go
down a steep or long hill.
4-21

When You Are Ready to Leave After
Parking on a
Hill
1. Apply your regular brakes and hold the pedal down
while
you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine
oil, belt, cooling system, and brake adjustment.
Each
of these is covered in this manual, and the Index
will help
you find them quickly. If you’re trailering, it’s
a
good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

The coolant level should be at or above FULL COLD. If
it isn’t, you may have a leak in the radiator
hoses, heater
hoses, radiator, water pump or somewhere else in the
cooling system.
r
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on check to
see if the electric engine fan is running. If the engine is
overheating, the fan should be running. If it isn’t, your
vehicle needs service.
How to Add Coolant to the Coolant Surge
Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD, add a 50/50 mixture of clean
water (preferably distilled) and a proper antifreeze at the
coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap,
is cool
before you do it.
(See “Engine Coolant” in the Index for
more information about the proper coolant mix.)
5-15

NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So use the recommended coolant.
1. You can remove the coolant surge tank pressure cap
when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose,
is no
longer hot. Turn the pressure cap slowly about
one-quarter turn to the left and then stop.
5-17

Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir
is
filled with hydraulic clutch fluid.
It isn’t a good idea to “top off’ your clutch fluid. Adding
fluid won’t correct
a leak.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
Refer to the Maintenance
Schedule to determine how
often you should check the
fluid level in your clutch
master cylinder reservoir
and for the proper fluid. See
“Owner Checks and
Services” and
“Recommended Fluids and
Lubricants” in the Index.
How to Check
If you can see fluid in the reservoir, the level is
acceptable.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low.
If you have a problem with
engine overheating, see “Engine Overheating”
in the
Index.
The proper coolant for your Oldsmobile will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F ( 128 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.

Used Replacement Wheels
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling,
speedometer/odometer calibration, headlamp aim, bumper height, vehicle ground clearance,
and tire or tire chain clearance to the
body and
chassis.
